一种油色谱在线监测设备通信仿真方法A communication simulation method for oil chromatography on-line monitoring equipment

技术领域technical field

本发明涉及一种油色谱在线监测设备通信仿真方法，特别是一种基于IEC61850的油色谱在线监测设备通信仿真方法，属于国际标准《变电站通信网络和系统》（IEC61850）的制造报文规范（MMS）在电力系统变电站自动化系统的应用的领域。The invention relates to a communication simulation method for oil chromatography online monitoring equipment, in particular to a communication simulation method for oil chromatography online monitoring equipment based on IEC61850, which belongs to the manufacturing message specification (MMS) of the international standard "Substation Communication Network and System" (IEC61850). ) in the application field of power system substation automation system.

背景技术Background technique

IEC61850标准是国际电工委员会TC57工作组针对解决变电站自动化系统面临的互操作新问题最新指定的《变电站通信网络和系统》系列标准。该标准得到国内外大部分主流厂家的支持，成为全球在变电站自动化领域唯一统一的标准，因此在在线监测油色谱智能电子设备通信中也得到越来越广泛的应用。The IEC61850 standard is the latest "Substation Communication Network and System" series standards designated by the International Electrotechnical Commission TC57 Working Group to solve the new interoperability problems faced by the substation automation system. This standard is supported by most mainstream manufacturers at home and abroad, and has become the only unified standard in the field of substation automation in the world. Therefore, it is also more and more widely used in the communication of intelligent electronic equipment for online monitoring of oil chromatography.

随着基于IEC61850标准一次设备在线监测在智能变电站的推广和应用，作为智能变电站重要特点的智能高级应用如一次设备健康状态评估等功能也在逐步试点应用中。但即使利用实际的在线监测智能电子设备，也很难对一次设备的故障进行模拟，而且一般在实验室很难具备这种条件，这对于跟踪并发现高级应用的问题造成了很大的困难。另一种方法是使用通用IEC61850/MMS服务端仿真，手动产生遥测、遥信量来模拟在线监测智能电子设备的通信行为，但在线监测智能电子设备发出的各模拟量数据间，模拟量与遥信量数据是尤其内在的逻辑关系的，这种逻辑关系正是模拟一次设备故障的关键所在，通用IEC61850/MMS服务端仿真很难满足相应的要求。因此如何简单高效地进行在线监测智能电子设备通信仿真模拟，对相关高级应用进行开发调试，以及在工程测试平台上进行验证是一个亟待解决的问题。With the promotion and application of online monitoring of primary equipment based on the IEC61850 standard in smart substations, intelligent advanced applications such as primary equipment health status assessment, which is an important feature of smart substations, are gradually being applied in pilot applications. But even with the actual on-line monitoring of intelligent electronic devices, it is difficult to simulate the failure of primary equipment, and it is generally difficult to have such conditions in the laboratory, which makes it very difficult to track and find problems in advanced applications. Another method is to use the general IEC61850/MMS server simulation to manually generate telemetry and remote signaling data to simulate the communication behavior of online monitoring intelligent electronic devices. Traffic data has an inherent logical relationship. This logical relationship is the key to simulating a device failure. The general IEC61850/MMS server simulation is difficult to meet the corresponding requirements. Therefore, it is an urgent problem to be solved how to simply and efficiently monitor the communication simulation of intelligent electronic devices online, develop and debug related advanced applications, and verify them on the engineering test platform.

附图说明Description of drawings

图1为本发明的仿真方法流程示意图。Fig. 1 is a schematic flow chart of the simulation method of the present invention.

具体实施方式Detailed ways

下面结合附图对本发明作更进一步的说明。The present invention will be further described below in conjunction with the accompanying drawings.

本发明实施例为一种基于IEC61850的油色谱在线监测设备通信仿真方法，其方法流程图如图1所示，包括如下步骤：An embodiment of the present invention is a communication simulation method for oil chromatography on-line monitoring equipment based on IEC61850. The flow chart of the method is shown in Figure 1, including the following steps:

步骤（1）：仿真启动IEC61850/MMS通信服务；Step (1): Simulate and start the IEC61850/MMS communication service;

步骤（2）：查询预存贮于SQL数据库中的待仿真油色谱在线监测智能电子设备某一次分析的各模拟量的值；Step (2): Query the value of each analog quantity analyzed by the online monitoring intelligent electronic device of oil chromatography to be simulated which is pre-stored in the SQL database;

步骤（3）：使用预配置的遥测越限产生告警规则，自动计算对应的告警遥信状态；Step (3): Use the pre-configured telemetry threshold violation to generate an alarm rule, and automatically calculate the corresponding alarm remote signaling status;

步骤（4）：以IEC61850报告形式发送各模拟量和告警遥信状态；Step (4): Send each analog quantity and alarm remote signaling status in the form of IEC61850 report;

步骤（5）：等待下次数据发送时刻，重复步骤2，直至所有预存数据发送完毕。Step (5): Wait for the next data sending time, repeat step 2 until all pre-stored data is sent.

所述步骤（1）具体是指：使用SQL数据库的按时标列排序查找功能，查找出某一次油色谱分析的各模拟量数据断面。The step (1) specifically refers to: using the SQL database sorting and searching function by time scale to find out each analog data section of a certain oil chromatographic analysis.

所述步骤（3）具体是指：使用预配置的遥测越限产生告警的规则，自动扫描个遥测量的当前模拟值，与各遥测的约越上限或越上上限值进行比较，并根据比较结果对对应的越上限遥信或越上上限遥信进行告警设置。The step (3) specifically refers to: use the pre-configured rules for generating alarms when telemetry exceeds the limit, automatically scan the current analog value of each telemetry, compare it with the approximate upper limit or upper limit value of each telemetry, and based on The comparison result sets an alarm for the corresponding upper limit remote signal or upper limit remote signal.

在线监测智能电子设备发出的各模拟量数据间，模拟量与遥信量数据是尤其内在的逻辑关系的，这种逻辑关系正是模拟一次设备故障的关键所在。一次设备故障时个模拟量信息可存贮于支持SQL的数据库中，针对仿真可使用轻量级的进程内数据库如SQLite，每一个遥测量的信息需包括断面序号、逻辑设备名、数据对象引用、遥测值等信息。Among the analog data sent by the online monitoring intelligent electronic equipment, the analog data and the remote signal data are particularly inherently logical. This logical relationship is the key to simulating a device failure. When a device fails, the analog information can be stored in a database that supports SQL. For simulation, a lightweight in-process database such as SQLite can be used. Each remote measurement information needs to include the section number, logical device name, and data object reference , telemetry values and other information.

由于IEC61850标准规定其中CID（Configured 智能电子设备 Description）文件包含了智能电子设备投运时的完整模型信息，仿真可使用实际被仿真设备的已有CID文件，解析获得该设备对外通信的所有信息和配置，启动IEC61850/MMS通信服务。Since the IEC61850 standard stipulates that the CID (Configured Intelligent Electronic Device Description) file contains the complete model information of the intelligent electronic device when it is put into operation, the simulation can use the existing CID file of the actual simulated device to analyze and obtain all the information and information of the external communication of the device. Configure and start the IEC61850/MMS communication service.

再使用SQL数据库的查找功存贮于数据库中的某一断面的所有遥测量数据，然后使用预配置的遥测越限产生告警的规则，自动扫描个遥测量的当前模拟值，与各遥测的约越上限或越上上限值进行比较，并根据比较结果对对应的越上限遥信或越上上限遥信进行告警设置，以IEC61850报告形式发送各模拟量和告警遥信状态。Then use the search function of the SQL database to store all the telemetry data of a certain section in the database, and then use the pre-configured rules for generating alarms when the telemetry exceeds the limit, automatically scan the current analog value of each telemetry, and the approximate value of each telemetry Compare the upper limit or the upper limit value, and set the alarm for the corresponding upper limit remote signal or upper limit remote signal according to the comparison result, and send each analog quantity and alarm remote signal status in the form of IEC61850 report.

然后判断是否所有预存数据都已发送完毕，如果发送完毕则停止发送；如过还有模拟数据待发送，则进入等待流程，准备进行下一次的故障模拟数据发送。Then judge whether all pre-stored data have been sent, and if the sending is finished, stop sending; if there is still simulation data to be sent, enter the waiting process and prepare for the next fault simulation data transmission.

本发明提供的一种基于IEC61850的油色谱在线监测设备通信仿真方法，可使用普通PC机建立油色谱在线监测智能电子设备仿真系统，用于代替实际在线监测智能电子设备等，产生一次设备的故障状态的在线监测数据，摆脱了智能变电站一次设备健康状态评等高级应用调试时对实际在线监测智能电子设备的依赖，同时简化了这些高级应用投运前调试工作的复杂度。The present invention provides an IEC61850-based communication simulation method for oil chromatography online monitoring equipment, which can use ordinary PCs to establish an oil chromatography online monitoring intelligent electronic equipment simulation system, which is used to replace actual online monitoring of intelligent electronic equipment, etc., to generate primary equipment failures The online monitoring data of status can get rid of the reliance on the actual online monitoring of intelligent electronic devices during the debugging of advanced applications of primary equipment health status rating in smart substations, and at the same time simplify the complexity of debugging work before these advanced applications are put into operation.

以上所述仅是本发明的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润色，这些改进和润色也应视为本发明的保护范围。The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made.
