本发明涉及一种智能变电站间隔层模拟自验收系统及方法，属于智能变电站技术领域。The invention relates to a simulation self-acceptance system and method for an intelligent substation interval layer, and belongs to the technical field of intelligent substations.
背景技术Background technique
调度系统是电网运行和控制的中枢，它对电网运行方式的改变和控制要通过变电站进行执行，调度系统通过和变电站之间的数据通道和通讯来实现对变电站的监视和控制。因此，变电站与调度系统之间数据传输的准确性是保证电网稳定运行的关键基础之一。The dispatching system is the center of power grid operation and control. It changes and controls the operation mode of the power grid through the substation. The dispatching system realizes the monitoring and control of the substation through the data channel and communication with the substation. Therefore, the accuracy of data transmission between the substation and the dispatching system is one of the key foundations to ensure the stable operation of the power grid.
当前从智能变电站与调度系统之间核对信息方式采用的是：一次设备→过程层设备→间隔层装置→站端监控系统→调度主站系统的流程，这个过程由于通讯链路复杂、中间环节较多、系统数据库制作人员水平不一等原因，存在调试过程易出错、检查环节较多、调度信息传动效率低下等技术问题。比如：在新建变电站建设过程中，首先由站端系统建设人员根据设计院蓝图制作变电站监控系统的信息点表，再由各级电网调度人员根据站端提供的信息点表挑选形成调度系统的信息点表，最后将该点表返回给站端建设人员制作远动机的各级调度转发表，实际的传动过程中都是由站端调试人员实际动作一次设备或保护与调度系统进行信号传动。此对点操作的不足之处在于：由于在此之前站端监控系统都已与实际一次设备进行了信号传动，再次传动造成重复工作；在一个新站建设周期中由于调度系统通道建设的延后，与调度系统对点过程一般都在建设末期进行，造成了该传动的过程时间紧任务重，极大的加重了系统运维人员的工作负担；另外，在老旧变电站的站控层系统改造的过程或调度系统的升级改造的过程中，如果要更换系统或进行站内系统的升级，必然牵涉到要重新制作各级调度转发表，此时由于站内一次设备都是运行设备，更换后无法进行对应信号的传动，只能进行部分位置信息的核对和遥测数据的核对，其他数据必须留待相关间隔停电检修才能完成，存在电力系统安全运行隐患。Currently, the method of checking information between the smart substation and the dispatching system is: primary equipment → process layer equipment → bay layer device → station monitoring system → dispatching master station system. There are many reasons, such as the different levels of system database production personnel, and there are technical problems such as error-prone debugging, many inspection links, and low efficiency of dispatching information transmission. For example: in the process of building a new substation, firstly, the station-side system construction personnel make the information point table of the substation monitoring system according to the blueprint of the design institute, and then the power grid dispatchers at all levels select and form the information of the dispatching system according to the information point table provided by the station end Point table, and finally return the point table to the construction personnel at the station to make dispatching and forwarding tables at all levels of the telemotor. In the actual transmission process, the commissioning personnel at the station actually operate the primary equipment or the protection and dispatching system for signal transmission. The shortcomings of this point-to-point operation are: because the station-side monitoring system has carried out signal transmission with the actual primary equipment before, the transmission again causes repeated work; in a new station construction period, due to the delay in the construction of the dispatching system channel , the point-to-point process with the dispatching system is generally carried out at the end of the construction period, resulting in tight time and heavy tasks for the transmission process, which greatly increases the workload of the system operation and maintenance personnel; in addition, the transformation of the station control layer system in the old substation In the process of upgrading or upgrading the dispatching system, if you want to replace the system or upgrade the system in the station, it will inevitably involve remaking the dispatching and forwarding tables at all levels. For the transmission of the corresponding signal, only part of the position information and telemetry data can be checked, and other data must be left for the relevant interval power outage maintenance to complete, and there are hidden dangers in the safe operation of the power system.

5、启动命令接收虚拟IED设备的链路启动：在第3步结束后，模拟系统会根据已经过人工确认的比对后的验收卡自动生成模拟对点信息库，接着模拟系统将启动对点命令接收虚拟IED设备的链路，在远动机接收到调度端自验收模块发过来的对应自动对点启动的预置令后，远动机将通过与间隔层的网络接口发送给模拟系统，模拟系统判断下发的对应启动命令接收虚拟IED设备的DO对象来进行相关遥测、遥信自验收的流程启动。5. Start the command to receive the link start of the virtual IED device: after the third step, the simulation system will automatically generate the simulation point-to-point information database according to the compared acceptance card that has been manually confirmed, and then the simulation system will start the point-to-point The command receives the link of the virtual IED device.
