【摘要】：相较于传统变电站,智能变电站的整个过程层已实现网络化。无论是一次系统的实际运行数据,还是二次设备之间的相互通信,都以报文的形式进行传输,但是报文不同于传统的测量值,比较复杂,要求运行维护人员对IEC61850规约相当熟悉才能分析,这给数字化变电站的运行、维护及事故原因判断、检修等日常工作带来了极大的不便。本论文目的就是研究智能变电站对网络报文分析系统的功能需求,设计一种可以对过程层主要报文类型(SV、GOOSE)进行捕捉、记录并完成分析的软件。主要研究内容及成果如下:首先,对传统变电站的局限性做出了分析,并介绍了IEC61850标准、特点以及关键技术,对比了智能变电站与传统型变电站的优缺点。针对过程层主要的两种报文类型(SV、GOOSE)都从结构、帧格式以及通信模式等方面做了详细的分析。接着,对软件设计做了总体性的概述,并将其按照不同的功能分为捕获,存储,解析,历史数据检索,分析处理等多个模块。接着针对各个模块进行了流程设计,并提出了实现方法。然后针对目前大容量储存方式存在的一些弊端,采用了一种较为新颖的多硬盘多分区的循环储存方式,有效避免了频繁读写导致的硬盘受损。最后通过搭建测试环境,对所设计功能模块进行了模拟测试,测试结果得出本文所设计的网络报文记录分析软件可以较好的完成相应的功能。
[Abstract]:Compared with traditional substation, the whole process layer of intelligent substation has been networked. Both the actual operation data of the primary system and the communication between the secondary devices are transmitted in the form of message, but the message is different from the traditional measurement value and is more complex. The operation and maintenance personnel are required to be familiar with IEC61850 protocol before analyzing, which brings great inconvenience to the operation, maintenance, accident reason judgment, repair and other daily work of digital substation. The purpose of this paper is to study the functional requirements of the network message analysis system in intelligent substation, and to design a software which can capture, record and complete the analysis of the main message types in the process layer. The main research contents and results are as follows: firstly, the limitations of traditional substation are analyzed, and the IEC61850 standard, characteristics and key technologies are introduced, and the advantages and disadvantages of intelligent substation and traditional substation are compared. The two main message types in the process layer are analyzed in detail, such as structure, frame format and communication mode. Then, the software design is summarized, and it is divided into capture, storage, analysis, historical data retrieval, analysis and processing modules according to different functions. Then, the process of each module is designed, and the implementation method is put forward. Then, aiming at some disadvantages of the current mass storage mode, a novel multi-disk and multi-partition cyclic storage mode is adopted, which can effectively avoid the damage of hard disk caused by frequent reading and writing. Finally, by setting up a test environment, the designed functional modules are simulated and tested. The test results show that the network message recording and analysis software designed in this paper can accomplish the corresponding functions better.
