本发明涉及一种智能变电站的图形化表达方法，具体涉及一种智能变电站防误闭锁逻辑图形化表达方法。The invention relates to a graphical expression method of an intelligent substation, in particular to a graphical expression method of an intelligent substation anti-mislocking logic.
背景技术Background technique
智能变电站作为智能电网的重要建设环节，截止目前国网公司已有1000多座智能变电站建成投运。为了防止误操作，规定了变电站五防运行规程，即是防止误分、合断路器，防止带负荷分、合隔离开关，防止带电挂(合)接地线(接地开关)，防止带接地线(接地开关)合断路器(隔离开关)，防止误入带电间隔五种防误，可分为站控层五防和间隔层五防，智能变电站间隔层五防是由位于间隔层的测控装置实现，间隔层五防是由位于间隔层的测控装置实现。Smart substations are an important part of the construction of smart grids. Up to now, more than 1,000 smart substations have been built and put into operation by State Grid Corporation of China. In order to prevent misoperation, the five-prevention operating procedures of the substation are stipulated, that is, to prevent the wrong opening and closing of the circuit breaker, to prevent the load opening and closing of the isolating switch, to prevent the live connection (closing) of the grounding wire (grounding switch), and to prevent the grounding wire ( Grounding switch) combined with circuit breaker (isolating switch) to prevent accidental entry into the charged interval. , the five defenses at the interval layer are realized by the measurement and control device located at the interval layer.
工程配置保存的五防联闭锁逻辑描述文件为每个厂家采用自己私有的描述方法，描述方法不规范。描述文件格式不一致，常见的描述文件有Word、Excel或AutoCAD等文件格式，有的为逻辑方程表达方式；在站控层系统和间隔层测控装置中的防误闭锁逻辑一般采用文本的方式描述，包含着复杂的语义，非专业人难以理解，不利于防误闭锁逻辑的阅读、查看和调试测试。因此，需要研究防误逻辑图形化表达方法。The five-proof interlocking logic description file saved in the project configuration adopts its own proprietary description method for each manufacturer, and the description method is not standardized. The format of the description file is inconsistent. Common description files include Word, Excel or AutoCAD file formats, and some are expressed in the form of logical equations; the anti-mislocking logic in the station control layer system and the bay layer measurement and control device is generally described in text. Contains complex semantics, which is difficult for non-professionals to understand, and is not conducive to reading, viewing and debugging of the anti-mistake locking logic. Therefore, it is necessary to study the graphical expression method of error prevention logic.
文献《智能化变电站间隔间五防闭锁的实现方式》(电工技术，2014,10：18-19)通过已有的MMS网络，应用GOOSE通信方式，跨间隔采集传输所需要的开入位置等联闭锁信息，通过模型文件建立订阅关系。结合装置自身灵活的PLC逻辑实现五防功能。主要解决测控及测保一体装置间五防闭锁功能的应用，对智能化变电站间隔、跨间隔装置间互相通信新的问题，满足智能化变电站通信和五防要求。The literature "Realization Method of Five-proof Locking Between Intervals of Intelligent Substations" (Electrical Technology, 2014, 10: 18-19) uses the existing MMS network to apply the GOOSE communication method to collect and transmit the opening and closing positions required for transmission across intervals. Blocking information, establish a subscription relationship through the model file. Combined with the flexible PLC logic of the device itself, the five defense functions are realized. It mainly solves the application of the five-prevention locking function between the measurement and control and measurement and protection integrated devices, and solves the new problem of communication between intelligent substation intervals and cross-interval devices, and meets the requirements of intelligent substation communication and five-prevention.
文献《智能变电站虚回路可视化方案研究与应用》(电网与清洁能源,2014,30(10):32～37)提出了一种可视化方案，能够快速解析SCD文件，自动输出单装置虚端子图、装置虚回路图、装置逻辑链路图、网络结构图等图纸，解决由于缺乏可视化工具而导致SCD文件中虚回路“看不见，摸不到”的问题。The document "Research and Application of Virtual Circuit Visualization Scheme in Smart Substation" (Grid and Clean Energy, 2014, 30(10): 32-37) proposes a visualization scheme that can quickly analyze SCD files and automatically output single-device virtual terminal diagrams, Drawings such as device virtual circuit diagrams, device logical link diagrams, and network structure diagrams solve the problem of "invisible and intangible" virtual circuits in SCD files due to the lack of visualization tools.
文献《基于间隔模型的图-库-规则-操作票自动生成方法》(电力系统自动化,2015,39(3):84～89)提出了自动生成五防规则和操作票的方案，其主要思路是：首先，建立包含典型一次间隔和典型二次间隔的典型间隔模型，然后，基于该模型分别研究了一次设备接线图-库自动生成、防误规则自动生成、操作票自动生成的方法。主要解决了人工配置五防联闭锁规则耗时效率低下问题。The document "Graph-Database-Rule-Operation Ticket Automatic Generation Method Based on Interval Model" (Automation of Electric Power Systems, 2015, 39(3): 84-89) proposed a scheme to automatically generate five prevention rules and operation tickets, the main idea of which is It is: firstly, a typical interval model including typical primary interval and typical secondary interval is established, and then, based on this model, the methods of automatic generation of primary equipment wiring diagram-library, automatic generation of error prevention rules, and automatic generation of operation tickets are studied respectively. It mainly solves the problem of time-consuming and inefficient manual configuration of five-defense interlocking rules.
综上，目前在智能变电站防误闭锁、可视化等方面开展了研究，研究的重点内容是防误闭锁逻辑规则自动化生成、智能变电站间隔与多间隔防误闭锁、智能变电站SCD文件虚回路可视化方案等，但是对于智能变电站联闭锁逻辑关系缺少图形化的表达方法。In summary, research has been carried out on anti-mis-locking and visualization of smart substations. The focus of the research is automatic generation of anti-mis-locking logic rules, smart substation interval and multi-interval anti-mis-locking, smart substation SCD file virtual loop visualization scheme, etc. , but there is no graphical expression method for the interlocking logic relationship of smart substations.

所述数据名称是与智能变电站监控系统数据库中数据名称保持一致，智能变电站监控系统数据由导入IEC 61850的信息模型自动生成，在监控系统数据库中采用数据的IEC61850索引reference来表示数据名称，reference应采用通用服务接口ACSI的表示方式，包含数据的功能约束(FC)，控制对象用FCD表示，位置和测量数据用FCDA表示。The data name is consistent with the data name in the intelligent substation monitoring system database. The intelligent substation monitoring system data is automatically generated by the information model imported into IEC 61850. In the monitoring system database, the IEC61850 index reference of the data is used to represent the data name.

所述逻辑树优先级规定所有同一层次上的联接词为同优先级，按先后顺序运算，但规定括号内的优先级比括号外的优先级高，对应存储结构上就是层次越深的优先级越高，可用括号来调整表达式的运算次序。The logic tree priority stipulates that all linking words on the same level have the same priority, and are calculated in sequence, but the priority inside the brackets is higher than the priority outside the brackets, and the corresponding storage structure is the priority of the deeper level The higher the value, the parentheses can be used to adjust the operation order of the expression.
