【摘要】：伴随着智能电网的发展,以及网络通信技术和变电站自动化技术的进步,变电站无人值守已经成为智能变电站建设的趋势。视频信息与环境量信息之间的联动,以及综合自动化系统与视频监控系统之间的信息交互是实现变电站无人值守的基础,是变电站辅助监控系统智能化的核心。但是目前变电站辅助监控系统通信协议种类繁多,联动实现方式具有局限性,随着电网规模的逐渐扩大,联动实现日益复杂,目前缺乏有效的方法对视频联动过程和结果进行测试。因此开展辅助监控系统内部以及与其他子系统之间联动的测试研究具有极强的现实意义和实际应用价值。本文采用事件仿真和协议模拟方式,依据变电站告警事件推送模式,基于IEC60870-5-104远动规约、SIP协议,利用事件注入技术、XML解析技术、网络编程技术等,在Visual Studio 2010开发平台下利用C++编程语言实现视频联动测试。主要工作如下:1)分析了辅助监控系统联动测试实现在智能变电站建设中的重要意义。通过分析现有辅助监控系统联动结构,并对目前联动系统中广泛应用的IEC60870-5-104远动规约和Q/GDW 517.1-2010《电网视频监控系统及接口第1部分:技术要求》进行研究。2)针对辅助系统联动方案,提出模拟仿真测试方法,通过研究事件注入、时序控制等技术,设计了联动协议测试和联动功能性能测试相结合的整体测试架构。3)根据模拟仿真测试方法,在对联动协议研究的基础上,利用接口测试和容错性测试方式,分别从正向协议互通性测试和反向协议容错性测试入手,实现了IEC60870-5-104远动规约测试和电网视频监控系统接口B联动部分协议测试。4)在协议测试基础上,建立告警事件模拟库,利用时序控制方法设计告警事件触发过程,实现模拟事件注入。利用XML解析等技术提取反馈报文信息,分析联动效率、联动准确度等性能指标,完成联动性能测试。5)通过与设备厂家的联调测试,验证了测试方法的正确性和测试系统稳定性,联动测试的实现对无人值守智能变电站辅助监控系统建设具有很好的实际应用价值。
[Abstract]:With the development of smart grid and the progress of network communication technology and substation automation technology, substation unattended substation has become the trend of intelligent substation construction. The linkage between video information and environmental quantity information, and the information interaction between integrated automation system and video surveillance system are the basis of realizing unattended substation, and the core of substation auxiliary monitoring system intelligence. However, at present, there are many kinds of communication protocols in substation auxiliary monitoring system, and the implementation of linkage has limitations. With the gradual expansion of power grid scale, the realization of linkage is becoming more and more complex. At present, there is a lack of effective methods to test the process and results of video linkage. Therefore, it is of great practical significance and practical application value to carry out the test research of the linkage between the auxiliary monitoring system and other subsystems. In this paper, event simulation and protocol simulation are adopted, according to the alarm event push mode of substation, based on IEC60870-5-104 telecontrol protocol, SIP protocol, event injection technology, XML analysis technology, network programming technology and so on, the video linkage test is realized by C programming language under the development platform of Visual Studio 2010. The main work is as follows: 1) the significance of linkage testing of auxiliary monitoring system in the construction of intelligent substation is analyzed. Based on the analysis of the linkage structure of the existing auxiliary monitoring system, the IEC60870-5-104 telecontrol protocol and Q/GDW 517.1 / 2010 "Power Network Video Surveillance system and Interface part 1: technical requirements", which are widely used in the linkage system, are studied. 2) aiming at the linkage scheme of the auxiliary system, the simulation and test method is put forward, and the techniques such as event injection and timing control are studied. The overall test architecture of linkage protocol test and linkage functional performance test is designed. 3) according to the simulation test method, on the basis of the research of linkage protocol, the interface test and fault tolerance test are used to start with the forward protocol interoperability test and the reverse protocol fault tolerance test, respectively. IEC60870-5-104 telecontrol protocol test and power network video surveillance system interface B linkage part protocol test are realized. 4) on the basis of protocol testing, the alarm event simulation library is established, and the alarm event trigger process is designed by using timing control method to realize analog event injection. Using XML analysis and other technologies to extract feedback message information, analyze linkage efficiency, linkage accuracy and other performance indicators to complete the linkage performance test. 5) through the joint test with equipment manufacturers, the correctness of the test method and the stability of the test system are verified. The realization of linkage testing has a good practical application value for the construction of unattended intelligent substation auxiliary monitoring system.
