【摘要】：随着现代电力系统技术的改革逐渐加深，数字化、智能化将会是电力系统的发展方向。而电力系统的数字化、智能化则意味着现代电力系统的变电站的也应朝着数字化、智能化的方向发展。通信是智能化变电站的基础，IEC61850作为一种通信规范则规定了变电站中的各IED之间的管理与通信，实现各个IED装置的无缝连接。变电站层、间隔层以及过程层是基于IEC61850规范划分的变电站通信体系。安全稳定控制装置作为二次设备存在于变电站的间隔层，为了使安全稳定控制装置能够适应智能化变电站的发展，安稳装置的通信模块就必须依据IEC61850规约进行改造，对于安稳装置与变电站层即与监控主站的通信研究则具有十分重要的意义。本文为了实现安稳装置与监控主站的通信，首先建立了安全稳定控制装置的IEC61850模型，并且分析安全稳定控制装置的功能，按照功能建立逻辑节点，其次对安稳数据进行分类，最后根据IEC61850标准的数据建模方法，将各种功能逻辑节点组合为安全稳定控制装置模型；并对安稳装置与监控主站的通信服务模型进行了详细的分析。在完成安稳装置与监控主站的通信模块的设计之前，需对安稳装置与监控主站的通信过程进行分析，，包括研究安全稳定控制装置的IEC61850模型与MMS（制造报文规范）的映射关系、MMS的抽象语法描述（ASN.1）以及MMS通信的报文解析，最后通过Qt编程完成安稳装置与监控主站的通信模块的设计，并实现与IEC61850客户端的连接完成了安稳装置与监控主站的数据传出。
[Abstract]:With the reform of modern power system technology deepening, digitization and intelligence will be the development direction of power system. The digitalization and intelligentization of the power system means that the substation of the modern power system should also develop towards the direction of digitalization and intelligentization. Communication is the foundation of intelligent substation, IEC61850, as a communication standard, stipulates the management and communication between the IED in the substation, and realizes the seamless connection of each IED device. Substation layer, interval layer and process layer are substation communication systems based on IEC61850 specification. As a secondary device, the safety and stability control device exists in the interval layer of the substation. In order to make the safety and stability control device adapt to the development of the intelligent substation, the communication module of the safety and stability device must be modified according to the IEC61850 protocol. It is of great significance to study the communication between the stable device and the substation layer and the monitoring master station. In order to realize the communication between the safety and stability device and the monitoring master station, the IEC61850 model of the safety and stability control device is established, and the function of the safety and stability control device is analyzed, the logical node is established according to the function, and the safety and stability data are classified. Finally, according to the data modeling method of IEC61850 standard, the various functional logic nodes are combined into the security and stability control device model, and the communication service model between the security device and the monitoring master station is analyzed in detail. Before completing the design of the communication module between the stabilizer and the monitoring master station, the communication process between the stabilizer and the monitoring master station should be analyzed. Including studying the mapping relationship between the IEC61850 model of the safety and stability control device and the IEC61850 (Manufacturing message Specification) and the abstract syntax description of the MMS (ASN.1) and the message analysis of the MMS communication. Finally, the design of the communication module between the stabilizer and the monitoring master station is completed by QT programming. And the connection with the IEC61850 client completes the data transmission of the stabilizer and the monitoring main station.
