预制化供电模块、供电控制方法及装置、存储介质Prefabricated power supply module, power supply control method and device, and storage medium

技术领域technical field

本公开涉及供电技术领域，尤其涉及一种预制化供电模块、供电控制方法及装置、存储介质。The present disclosure relates to the technical field of power supply, and in particular, to a prefabricated power supply module, a power supply control method and device, and a storage medium.

背景技术Background technique

图1所示为一种N+1的UPS的分布式冗余供电示意图。分布式冗余N+1的UPS，标准分布式冗余缺点是初期部署需要以多套变压器和相应UPS做一次投资，如果初期负载容量较少，分布式冗余投资难以做到灵活性。例如上面配置3套变压器和UPS，实际初期负载需要1台变压器满载的情况下，做分布式冗余(Distributed Redundant)系统初投资较高，总之，分布式冗余N+1的UPS缺点是初期部署需要以多套变压器和相应UPS做一次投资，如果初期负载容量较少，分布式冗余投资难以做到灵活性。Figure 1 shows a schematic diagram of a distributed redundant power supply of an N+1 UPS. Distributed redundancy N+1 UPS, the disadvantage of standard distributed redundancy is that initial deployment requires multiple sets of transformers and corresponding UPS to make one investment. If the initial load capacity is small, it is difficult to achieve flexibility in distributed redundancy investment. For example, three sets of transformers and UPS are configured above. When the actual initial load requires one transformer to be fully loaded, the initial investment of a distributed redundant system is relatively high. In short, the disadvantage of distributed redundant N+1 UPS is the initial Deployment requires an investment of multiple sets of transformers and corresponding UPS. If the initial load capacity is small, it is difficult to achieve flexibility in distributed redundancy investment.

图2是2+1的UPS的分布式冗余供电模块，切换到3+1的UPS的分布式冗余供电模块。从前例的2+1的UPS的分布式冗余，扩容到3+1的UPS的分布式冗余，负载的配电组合分配会变成6种，即AB,AC,AD,BC,BD,CD。如果升级到4+1，则有10种组合。这种设计方式的缺点是，扩容时候的负载分配组合复杂度提升较多，提高设计复杂度以及运营难度。Figure 2 shows the distributed redundant power supply module of the 2+1 UPS, which is switched to the distributed redundant power supply module of the 3+1 UPS. From the distributed redundancy of the 2+1 UPS in the previous example to the distributed redundancy of the 3+1 UPS, the distribution of the load distribution will become 6 types, namely AB, AC, AD, BC, BD, CD. If you upgrade to 4+1, there are 10 combinations. The disadvantage of this design method is that the complexity of the load distribution combination during expansion is greatly increased, which increases the design complexity and operation difficulty.

图2是另一种分布式冗余供电模块，N+1的UPS的供电模组设计方式还有公共冗余(Block Redundant)系统，虽然能够解决分期部署问题，但是因为引入静态切换开关(STS)，整体供电模块成本较高。Figure 2 is another distributed redundant power supply module. The N+1 UPS power supply module design method also has a public redundant (Block Redundant) system. Although it can solve the problem of staged deployment, it is difficult to ), the overall power supply module cost is higher.

具体实施方式Detailed ways

以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.

在后续的描述中，使用用于表示元件的诸如“模块”、“模组”或“电路”的后缀仅为了有利于本公开的说明，其本身没有特定的意义。因此，“模块”、“模组”或“电路”可以混合地使用。In the ensuing description, suffixes such as 'module', 'module' or 'circuit' used to denote elements are used only to facilitate the description of the present disclosure and have no specific meaning per se. Thus, "module", "module" or "circuit" may be used interchangeably.

如图3及图4所示，本公开实施例提供一种预制化供电模块，所述预制化供电模块包括：As shown in FIG. 3 and FIG. 4 , an embodiment of the present disclosure provides a prefabricated power supply module, where the prefabricated power supply module includes:

所述主用变压器配置有M+1的主用不间断电源UPS；其中，所述M+1的主用UPS的输出相互之间构成分布式冗余备份；The main transformer is configured with an M+1 main uninterruptible power supply UPS; wherein, the outputs of the M+1 main UPS form a distributed redundant backup with each other;

连锁开关电路，一个所述连锁开关电路对应于一个所述主用UPS；an interlocking switch circuit, one of the interlocking switch circuits corresponds to one of the main UPSs;

N+1变压器中N主用变压器和1备用变压器。1主用变压器对应于一个供电模块。1备用变压器连接在公共备份回路上，用于对N主用变压器所在供电模块进行供电备份。N+1变压器中的任意一个变压器能够提供的功率容量可等于所连接负载所需的功率容量。Among the N+1 transformers, there are N main transformers and 1 backup transformers. 1 The main transformer corresponds to one power supply module. 1. The backup transformer is connected to the public backup circuit, and is used for power supply backup for the power supply module where the N main transformer is located. The power capacity that any one of the N+1 transformers can provide can be equal to the power capacity required by the connected load.

M+1的UPS中M的UPS能够提供的功率值，可等于一个主用变压器后端所连接负载的总功率容量。其中，M+1的UPS中1的UPS可用于形成分布式冗余备份。In the M+1 UPS, the power value that the M UPS can provide can be equal to the total power capacity of the load connected to the back end of a main transformer. Among them, the UPS of 1 in the M+1 UPS can be used to form a distributed redundant backup.

参考图7所示，在一个主用变压器下方的任意一路负载500kVA且有3路负载，则负载功率容量为1500kVA，而N+1变压器表示，在不考虑UPS效率和变压器输出配电损耗的情况下，变压器为1500kVA*(N+1)，即一个主用变压器的功率容量就是1500kVA，即主用变压器能够提供的功率等于其后端所连接负载所需的负载功率容量。负载功率为1500kVA(500kVA*3)，则UPS配置(2+1)*750kVA，所以是M+1的UPS。在本公开实施例中提供的预制化供电模块中采用的N+1变压器包括：N主用变压器和1备用变压器。每一个主用变压器后连接有M+1的主用的UPS。Referring to Figure 7, if any one of the loads under a main transformer is 500kVA and there are 3 loads, the load power capacity is 1500kVA, and the N+1 transformer means that the UPS efficiency and the transformer output distribution loss are not considered. Below, the transformer is 1500kVA*(N+1), that is, the power capacity of a main transformer is 1500kVA, that is, the power that the main transformer can provide is equal to the load power capacity required by the load connected to the back end. The load power is 1500kVA (500kVA*3), then the UPS is configured with (2+1)*750kVA, so it is an M+1 UPS. The N+1 transformers used in the prefabricated power supply modules provided in the embodiments of the present disclosure include: N main transformers and 1 backup transformers. Each main transformer is connected with M+1 main UPS.

将连锁开关电路设置在主用UPS的后端，具有成本低的特点。The interlock switch circuit is arranged at the back end of the main UPS, which has the characteristics of low cost.

在本公开实施例中，主用UPS为位于主用路径上的UPS。In the embodiment of the present disclosure, the active UPS is a UPS located on the active path.

这M+1的主用UPS的输出可彼此互为备份，构成了分布式冗余备份，通过这种分布式冗余备份确保负载双路持续供电。The outputs of the M+1 main UPS can back up each other to form a distributed redundant backup. Through this distributed redundant backup, the two-way continuous power supply of the load can be ensured.

所述变压器用于将市电电压转换为负载所需的电压。例如，变压器可以将市电电压进行降压后输入电压负载，或将市电电压升压后输入高压负载内。The transformer is used to convert the mains voltage into the voltage required by the load. For example, the transformer can step down the mains voltage and input it into a voltage load, or boost the mains voltage and input it into a high-voltage load.

在M+1的UPS的后端设置有一个造价成本低的连锁开关电路。这个连锁开关电路至少包含第一开关和第二开关。A low-cost interlock switch circuit is arranged at the rear end of the M+1 UPS. This interlock switch circuit includes at least a first switch and a second switch.

参考图3所示，公共备份回路即为图3中的RESERVE POWER BLOCK。图3中的POWERBLOCK-1是主用变压器所在的主用UPS所在主用路径的主供电力模块。Referring to Figure 3, the common backup circuit is the RESERVE POWER BLOCK in Figure 3. The POWERBLOCK-1 in Figure 3 is the main power module of the main path where the main UPS where the main transformer is located is located.

图4为在图3基础上灵活扩展的示意图，可见采用本公开实施例提供的预制化供电模块实现了灵活和简便扩展。图4在图3的基础上增加了POWER BLOCK-2至POWER BLOCK-S。S可为大于或等于2的任意正整数。FIG. 4 is a schematic diagram of flexible expansion on the basis of FIG. 3 . It can be seen that flexible and simple expansion is achieved by using the prefabricated power supply module provided by the embodiment of the present disclosure. Figure 4 adds POWER BLOCK-2 to POWER BLOCK-S on the basis of Figure 3 . S can be any positive integer greater than or equal to 2.

本公开实施例提供的供电模块是一种预制化供电模块，可以为生产厂家预先设置好，购买者直接购买安装即可。The power supply module provided by the embodiment of the present disclosure is a prefabricated power supply module, which can be preset by a manufacturer, and can be directly purchased and installed by a purchaser.

在本公开实施例中，所述预制化供电模块连接的负载可为各种类型的负载。在一些实施例中，所述负载可为IT负载。例如，这种预制化供电模块可应用于数据中心，用于向数据中心的服务器供电。In the embodiment of the present disclosure, the loads connected to the prefabricated power supply module may be various types of loads. In some embodiments, the load may be an IT load. For example, such a prefabricated power supply module can be applied to a data center to supply power to servers in the data center.

本公开实施例提供的电力模块是一种预制化的电力模块，可以简称预制化电力模块。The power module provided by the embodiment of the present disclosure is a prefabricated power module, which may be referred to as a prefabricated power module.

在本公开实施例中，该负载可为任意负载，具体可如图3及图4所示的服务器。若一个服务器有两个电源，该服务器还可以称之为双电源服务器。In this embodiment of the present disclosure, the load may be any load, and specifically may be a server as shown in FIG. 3 and FIG. 4 . If a server has two power supplies, the server can also be called a dual power supply server.

在一个实施例中，备份公共回路上可以上设置有M的UPS，该UPS相对于主用路径上的UPS称之为备份UPS。参考图7所示，一个主路变压器的后端连接有3路500kVA的负载，一个主用变压器后端连接M+1的UPS，例如(2+1)*750kVA的UPS的负载功率容量。而参考图7所示，在公共备用回路上的UPS能够提供的功率容量为1500kVA，因此以750kVA为一个单位，则公共备用回路上是M的UPS。M的UPS能够提供的功率容量，可等于一个主用变压器后端连接的负载的功率容量。M的UPS可以理解为M个单位的UPS。值得注意的是：M的UPS可提供的功率可等于所连接负载的负载功率。In one embodiment, M UPSs may be arranged on the backup common circuit, and the UPSs are called backup UPSs relative to the UPSs on the main path. Referring to Figure 7, the rear end of a main transformer is connected to three 500kVA loads, and the rear end of a main transformer is connected to an M+1 UPS, such as (2+1)*750kVA UPS load power capacity. Referring to Figure 7, the power capacity that the UPS on the common backup circuit can provide is 1500kVA, so taking 750kVA as a unit, the UPS on the public backup circuit is M UPS. The power capacity that M's UPS can provide can be equal to the power capacity of the load connected to the back end of a main transformer. M UPS can be understood as M units of UPS. It is worth noting that the power that M's UPS can provide can be equal to the load power of the connected load.

在一个实施例中，如图3和图4所示，所述预制化供电模块还包括：In one embodiment, as shown in FIG. 3 and FIG. 4 , the prefabricated power supply module further includes:

该外部维修旁路位于主用UPS外，在主用UPS不工作或隔离维护时，可以通过闭合该外部外修旁路上的开关，以导通该外部维修旁路，市电经过变压器输出通过该外部维修旁路向负载供电。The external maintenance bypass is located outside the main UPS. When the main UPS is out of work or isolated for maintenance, the external maintenance bypass can be turned on by closing the switch on the external external maintenance bypass. External maintenance bypass supplies power to the load.

在主用UPS正常工作时，即主用UPS可向负载正常提供电力时，该外部维修旁路上的开关断开，即外部维修旁路断开。When the main UPS is working normally, that is, when the main UPS can supply power to the load normally, the switch on the external maintenance bypass is disconnected, that is, the external maintenance bypass is disconnected.

在一个实施例中，所述预制化供电模块还包括：隔离间。In one embodiment, the prefabricated power supply module further includes: an isolation room.

该隔离间用于隔离供电模组中需要隔离的不同电子器件，从而提高供电安全性。The isolation room is used to isolate different electronic devices that need to be isolated in the power supply module, thereby improving power supply security.

例如，不同的所述变压器位于不同的隔离间内。For example, different said transformers are located in different compartments.

不同的变压器位于不同的隔离间中，该隔离间可为各种类型的隔离间，例如，方舱隔离间或集装箱式隔离间。在隔离间除了放置变压器，还可以放置配电柜，例如，低压配电柜。Different transformers are located in different isolation rooms, which may be various types of isolation rooms, such as shelter isolation rooms or container-type isolation rooms. In addition to placing transformers in the isolation room, power distribution cabinets, such as low-voltage power distribution cabinets, can also be placed.

为了供电安全，还可以在每一个隔离间中设置消防设备，该消防设备包括但不限于消防气瓶。For the safety of power supply, fire-fighting equipment can also be installed in each isolation room, and the fire-fighting equipment includes but is not limited to fire-fighting gas cylinders.

在一些实施例中，不同的UPS位于不同的隔离间内。同样的通过隔离间隔离不同的UPS，达到安全供电的目的。In some embodiments, different UPSs are located in different compartments. In the same way, the purpose of safe power supply is achieved by isolating different UPSs through the isolation room.

此处不同的UPS位于不同的隔离间，此处的UPS包括：主用UPS和备用UPS。即不管是主用UPS还是备用UPS，只要是不同的UPS将被隔离在隔离间。Different UPSs here are located in different isolation rooms, and the UPSs here include: the main UPS and the backup UPS. That is, whether it is the main UPS or the standby UPS, as long as it is a different UPS, it will be isolated in the isolation room.

在一个实施例中，任意一个UPS(即，主用UPS和备用UPS)可包含多个电池组，这些电池组在UPS处于充电模式时，通过UPS内部充电器接收输入电力并存储电力。在UPS处于放电模式时，这些电池组可以将存储的电力释放，从而实现对负载供电。In one embodiment, either UPS (ie, the primary UPS and the backup UPS) may contain multiple battery packs that receive input power and store power through the UPS internal charger when the UPS is in charging mode. When the UPS is in discharge mode, these battery packs can release stored power to power the load.

同样地，在配置有UPS的隔离间内可设置配电柜，例如，低压配电柜。Likewise, a power distribution cabinet, eg, a low-voltage power distribution cabinet, may be provided in the isolation room equipped with the UPS.

同样地，在UPS所在的隔离间内设置消防设备，同样地，这个消防设备包括但不限于消防气瓶。Likewise, fire-fighting equipment is set up in the isolation room where the UPS is located. Likewise, the fire-fighting equipment includes but is not limited to fire-fighting gas cylinders.

在一些实施例中，变压器和UPS位于不同的隔离间内，例如，具体的实现方案可参考图8。In some embodiments, the transformer and the UPS are located in different isolation rooms, for example, reference may be made to FIG. 8 for a specific implementation scheme.

为了进一步提升供电安全，变压器和UPS也将位于不同的隔离间中。To further enhance power supply security, the transformer and UPS will also be located in separate isolation rooms.

参考图8所示，不同的变压器位于不同的隔离间中，该隔离间可为各种类型的隔离间，例如，方舱隔离间或集装箱式隔离间。在隔离间除了放置变压器，还可以放置配电柜，例如，低压配电柜。Referring to FIG. 8 , different transformers are located in different isolation rooms, which may be various types of isolation rooms, such as shelter isolation rooms or container-type isolation rooms. In addition to placing transformers in the isolation room, power distribution cabinets, such as low-voltage power distribution cabinets, can also be placed.

在一些实施例中，不同的UPS位于不同的隔离间内。同样的通过隔离间的隔离不同的UPS，达到安全供电的目的。In some embodiments, different UPSs are located in different compartments. In the same way, the purpose of safe power supply is achieved by isolating different UPSs between the isolation rooms.

如图5所示，本公开实施例提供一种供电控制方法，其特征在于，应用于前述任意一个实施例提供的预制化供电模块中，所述方法包括：As shown in FIG. 5 , an embodiment of the present disclosure provides a power supply control method, which is characterized in that, when applied to the prefabricated power supply module provided by any one of the foregoing embodiments, the method includes:

Use UPS to enter discharge mode and discharge automatically;

S120：若存在所述主用UPS的输入异常，将输入异常的所述主用UPS的所述连锁开关电路切换到第二开关状态。S120: If there is an abnormal input of the main UPS, switch the interlock switch circuit of the main UPS with abnormal input to a second switch state.

任意一个主用UPS后端具有连锁开关电路，至少分别连接在该UPS的输出端和公共备份回路上，如此，连锁开关电路可以在一个主用UPS的主用路径和公共备份回路之间切换。The back end of any main UPS has an interlocking switch circuit, which is at least connected to the output end of the UPS and the common backup circuit, so that the interlocking switch circuit can switch between the main path and the common backup circuit of a main UPS.

连锁开关电路包含至少第一开关和第二开关，且具有第一开关状态和第二开关状态；在第一开关状态下，第一开关闭合且第二开关断开。此时主用UPS向外供电或者变压器输出的电路通过主用UPS的内部旁路提供给负载；因此负载可以获得电力。而在第二开关状态下，第一开关断开和第二开关闭合，此时负载通过公共备用回路获取电力。The interlock switch circuit includes at least a first switch and a second switch, and has a first switch state and a second switch state; in the first switch state, the first switch is closed and the second switch is open. At this time, the main UPS supplies power to the outside or the output circuit of the transformer is supplied to the load through the internal bypass of the main UPS; therefore, the load can obtain power. In the second switch state, the first switch is opened and the second switch is closed, and at this time, the load obtains power through the common backup circuit.

公共备份回路和主用UPS所在路径，均可通过采样电阻进行电流和/或电压的采样，若采样电阻上的电流为零或者电压为零，可认为主用UPS所在路径或公共备份回路异常。当然检测主用UPS所在路径和公共备份回路异常的方式有很多种，具体实现不局限于该中。Both the common backup circuit and the path where the main UPS is located can sample current and/or voltage through the sampling resistor. If the current or voltage on the sampling resistor is zero, it can be considered that the path where the main UPS is located or the common backup circuit is abnormal. Of course, there are many ways to detect the abnormality of the path where the main UPS is located and the public backup circuit, and the specific implementation is not limited to this.

在所述主用UPS的输入时，所述主用UPS自动进入到放电模式，在放电模式下，所述主用UPS将自身存储的电能释放，从而向负载供电。When the main UPS is input, the main UPS automatically enters the discharge mode, and in the discharge mode, the main UPS releases the electric energy stored by itself, thereby supplying power to the load.

在主用UPS的输入异常时，可以通过连锁开关电路的开关状态切换，使得导通的路径从主用UPS的主用路径切换到公共备份回路。若公共备份回路被导通后，备份用的变压器的输出端输出的电力可以从公共备份回路输入负载，实现对负载供电。When the input of the main UPS is abnormal, the switch state of the interlock switch circuit can be switched, so that the conducting path is switched from the main path of the main UPS to the common backup circuit. If the common backup circuit is turned on, the power output from the output end of the transformer for backup can be input to the load from the common backup circuit to supply power to the load.

在一些实施例中，所述若存在所述主用UPS的输入异常，将输入异常的所述主用UPS的所述连锁开关电路切换到第二开关状态，包括：In some embodiments, if there is an abnormal input of the main UPS, switching the interlocking switch circuit of the main UPS with abnormal input to a second switch state includes:

在确定出主用UPS的输入异常且异常持续时长达到第一设定时长，再进行连锁开关电路的开关状态切换，一方面减少主用UPS的输入异常的误判导致的切换，另一方面为了排除了主要UPS的短暂异常可恢复正常导致的频繁切换，会对主用UPS的输入异常进行计时，在主用UPS的输入异常持续时长达到第一设定时长之后，才使得连锁开关电路切换到导通公共备份回路。After it is determined that the input of the main UPS is abnormal and the abnormal duration reaches the first set time, the switch state of the chain switch circuit is switched. Excluding the frequent switching caused by the short-term abnormality of the main UPS and returning to normal, the input abnormality of the main UPS will be timed. After the input abnormality of the main UPS reaches the first set time, the interlock switch circuit will be switched to. Turn on the common backup circuit.

此时第一设定时长可为：根据该第一开关前端连接主用UPS存储的电量和负载的耗电量相关。例如，第一设定时长与主要UPS存储的电量正相关，与负载的耗电量负相关。In this case, the first set duration may be: according to the connection between the front end of the first switch and the main UPS, the stored power is related to the power consumption of the load. For example, the first set duration is positively related to the power stored by the main UPS, and negatively related to the power consumption of the load.

在一些实施例中，所述方法还包括：In some embodiments, the method further includes:

监控各主用UPS的存储电量；Monitor the stored power of each main UPS;

根据所述存储电量和所述负载的平均耗电量，确定所述第一设定时长。The first set duration is determined according to the stored power and the average power consumption of the load.

总之，通过上述方式确定第一设定时长，能够确保通过主用UPS已有的电量实现对负载的不间断供电。In conclusion, by determining the first set duration in the above manner, it can be ensured that the uninterrupted power supply to the load can be achieved by using the existing power of the main UPS.

确定所述UPS的输入异常是否排除；Determine whether the input abnormality of the UPS is eliminated;

确定所述UPS的输入异常排除后维持正常的持续时长是否达到第二设定时长；Determine whether the normal duration of the UPS after the abnormal input of the UPS is eliminated reaches the second set duration;

若所述UPS的输入异常排除后维持正常的持续时长达到所述第二设定时长，将连锁开关电路切换到第二开关状态。If the input abnormality of the UPS is eliminated and the normal continuous duration reaches the second set duration, the interlocking switch circuit is switched to the second switch state.

在主用UPS的输入故障(即异常)一段时间后，还会检测主用UPS的主用路径的异常是否排除，若排除了可以及时切换回主用路径进行供电。After the input fault (ie abnormality) of the main UPS for a period of time, it will also detect whether the abnormality of the main path of the main UPS is eliminated. If it is eliminated, it can be switched back to the main path for power supply in time.

但是为了避免主用路径异常的假性排除，会对排除异常的主用UPS的输入异常排除恢复到正常的持续时长进行计时，若计时达到第二设定时长，说明主用UPS的主用路径异常假性排除的概率比较小，此时连锁开关电路导通的路径可以从公共备份回路切换到主用UPS所在路径。However, in order to avoid the false elimination of the abnormality of the main path, the duration of the abnormal input of the main UPS that has been eliminated and returned to normal will be counted. If the timing reaches the second set time, it indicates the main path of the main UPS The probability of abnormal false exclusion is relatively small. At this time, the path where the chain switch circuit is turned on can be switched from the public backup circuit to the path where the main UPS is located.

第二设定时长可略大于UPS的主用路径异常假性排除的时长，从而减少不必要的切换。The second set duration may be slightly longer than the duration for falsely eliminating the abnormality of the main path of the UPS, thereby reducing unnecessary switching.

如图3所示，本公开实施例提供的预制化供电模块，对负载实现了双电源供电，如此，负载只要有一路电源向其供电时，则负载可以持续工作。As shown in FIG. 3 , the prefabricated power supply module provided by the embodiment of the present disclosure implements dual power supply for the load, so that the load can continue to work as long as there is one power supply to supply power to the load.

故在一些实施例中，所述方法还包括：Therefore, in some embodiments, the method further includes:

一个所述主用变压器的输出异常时，控制异常的所述主用变压器下的至少两个所述主用UPS后端的连锁开关电路等待不同的时长之后，切换到所述第二开关状态。When the output of one of the main transformers is abnormal, the interlock switch circuits at the rear ends of at least two main UPSs under the abnormal main transformer are switched to the second switch state after waiting for different time periods.

例如，一个主用变压器自身异常，导致主用变压器的输出异常；或者，主用变压器后端连接的母线异常，也会导致主用变压器的输出异常。若主用变压器的输出异常，则连接在该主用变压器后端的所有主用UPS的输入都异常，为了对负载持续供电，则会触发主用UPS后端连接的连锁开关电路从第一开关状态切换到第二开关状态。For example, an abnormality of the main transformer itself will cause the output of the main transformer to be abnormal; or, the abnormality of the bus connected to the rear end of the main transformer will also cause the output of the main transformer to be abnormal. If the output of the main transformer is abnormal, the inputs of all the main UPS connected to the back end of the main transformer are abnormal. In order to continuously supply power to the load, the chain switch circuit connected to the back end of the main UPS will be triggered to change from the first switch state. Switch to the second switch state.

为了避免连接在同一个负载上的两个主用UPS的输出都中断，一个主用变压器下的多个连锁开端电路在检测到需要进行状态切换后，等待不同的时长从第一开关状态切换到第二开关状态，从而避免与同一个负载连接的两个连锁开关电路同时处于开关状态切换中导致的负载供电中断现象。In order to avoid the interruption of the outputs of the two main UPS connected to the same load, after detecting the need for state switching, the multiple chain start circuits under one main transformer wait for different time periods to switch from the first switch state to The second switch state, thereby avoiding the phenomenon of load power supply interruption caused by two interlocking switch circuits connected to the same load being in the switching state at the same time.

值得注意的是，连锁开关电路从第一开关状态切换到第二开关状态的等待的时长，不能超过对应主用UPS的电池组能够持续供电的时长，即连锁开关电路等待切换到第二开关状态的时间，需在主用UPS的电池组电量放尽之前结束。It is worth noting that the waiting time for the interlocking switch circuit to switch from the first switching state to the second switching state cannot exceed the duration that the battery pack corresponding to the main UPS can continue to supply power, that is, the interlocking switching circuit waits for switching to the second switching state. The time must end before the battery pack of the main UPS is discharged.

本公开实施例还提供一种供电控制装置，所述装置包括：Embodiments of the present disclosure also provide a power supply control device, the device comprising:

检测模块，用于检测各个主用UPS的输入是否正常；其中，在所述主用UPS的输入正常时，所述控制连锁开关电路处于第一开关状态；所述主用UPS的输入异常时，所述主用UPS进入到放电模式并自动放电；The detection module is used to detect whether the input of each main UPS is normal; wherein, when the input of the main UPS is normal, the control interlock switch circuit is in the first switching state; when the input of the main UPS is abnormal, the The main UPS enters the discharge mode and discharges automatically;

在一个实施例中，所述装置还包括：In one embodiment, the apparatus further includes:

排除模块，用于确定所述主用UPS的输入异常是否排除；An exclusion module, used to determine whether the input abnormality of the main UPS is eliminated;

判断模块，用于确定所述主用UPS的主用输入异常排除后维持正常的持续时长是否达到第二设定时长；a judging module, configured to determine whether the normal duration of the main input of the main UPS after the exception is eliminated reaches the second set duration;

所述切换模块，还用于若所述主用UPS的输入异常排除后维持正常的持续时长达到所述第二设定时长，所述连锁开关电路切换到所述第一开关状态。The switching module is further configured to switch the interlocking switch circuit to the first switch state if the normal duration of the main UPS after the input abnormality is eliminated reaches the second set duration.

在一些实施例中，所述切换模块，还被配置为一个所述主用变压器的输出异常时，异常的所述主用变压器下的多个所述主用UPS后端的连锁开关电路等待不同的时长之后，切换到所述第二开关状态。In some embodiments, the switching module is further configured so that when the output of one of the main transformers is abnormal, the chain switch circuits at the back ends of the plurality of main UPSs under the abnormal main transformer wait for different After the time period, switch to the second switch state.

参考图7所示，本公开实施例提供的预制化供电模块的供电控制方法可包括：Referring to FIG. 7 , the power supply control method of the prefabricated power supply module provided by the embodiment of the present disclosure may include:

判断主用UPS输入是否正常；Determine whether the main UPS input is normal;

若否，则主用UPS放电模式进行主用UPS放电；If not, the main UPS discharge mode is used to discharge the main UPS;

若是，则说明主用UPS处于在线模式，即连接在供电电路中由变压器输出的电力进行供电；If so, it means that the main UPS is in the online mode, that is, it is connected to the power supply circuit to supply power from the power output by the transformer;

若主用UPS处于放电模式，则进一步判断主用UPS放电是否超过对应的预设时长；If the main UPS is in discharge mode, it is further judged whether the discharge of the main UPS exceeds the corresponding preset duration;

若是超过预设时长，切换到公共备份回路。If it exceeds the preset time, switch to the public backup circuit.

有一组变压器的UPS输出作为公共备份，即构成公共备份回路，可以给一组或多组主用变压器模组的UPS作为备份供电。The UPS output of a group of transformers is used as a common backup, that is, a common backup circuit is formed, which can supply one or more groups of UPSs of the main transformer module as a backup power supply.

参考图9所示，主用变压器后端连接有M的主用UPS，在图9所示的预制化供电模块中的M为3。每一路主用UPS后端连接有一个连锁开关电路，即在图9中一路主用变压器后端连接有3路连锁开关电路，分别是连锁开关电路A、连锁开关电路B及连锁开关电路C。Referring to FIG. 9 , the main UPS of M is connected to the rear end of the main transformer, and M is 3 in the prefabricated power supply module shown in FIG. 9 . There is an interlocking switch circuit connected to the back end of each main UPS, that is, in Figure 9, there are 3 interlocking switch circuits connected to the rear end of one main transformer, namely interlocking switch circuit A, interlocking switch circuit B and interlocking switch circuit C.

连锁开关电路的切换过程为先断后通，为避连锁开关电路A、连锁开关电路B及连锁开关C，同时切换到备用UPS上造成负载断电，因此需要限定切换顺序。在正常状态下，公共备份供电模组，例如通过配置可编程逻辑控制器(PLC)等控制，检测每个主用供电模块所在的供电模组的UPS工作状态。设定供电模组下，当UPS处于放电模式下，连锁开关电路A、连锁开关电路B及连锁开关电路C切换到第二开关状态的等待时长分别为：Ta、Tb及Tc。其中，Ta≠Tb≠Tc。Ta、Tb及Tc的计时单位可为秒或者毫秒。The switching process of the interlocking switch circuit is to break first and then make it. In order to avoid the interlocking switch circuit A, the interlocking switch circuit B and the interlocking switch C, and switching to the standby UPS at the same time, the load will be cut off, so the switching sequence needs to be limited. In a normal state, the public backup power supply module, for example, is controlled by configuring a programmable logic controller (PLC) to detect the UPS working state of the power supply module where each main power supply module is located. Under the setting of the power supply module, when the UPS is in discharge mode, the waiting time for the interlock switch circuit A, the interlock switch circuit B and the interlock switch circuit C to switch to the second switch state are Ta, Tb and Tc respectively. Among them, Ta≠Tb≠Tc. The timing units of Ta, Tb and Tc can be seconds or milliseconds.

如果主用UPS还不能恢复正常在线供电状态(例如市电没有恢复或发电机没有正常投入)，则启动切换，切换等待时间不得超过每组主用UPS的电池后备时间，否则会出现电池放电结束仍没切换导致负载断电。If the main UPS cannot restore the normal online power supply status (for example, the mains has not been restored or the generator has not been put into normal operation), start the switching, and the switching waiting time shall not exceed the battery backup time of each main UPS, otherwise the battery discharge will end. The load is powered off due to still not switching.
