| With the development of substation automation technology, the structure of modern grid becomes more and more complicated and Digital Substation will be the development trend for future substation. IEC61850Standard does not only improve the performance, but also put forward a new problem about how to monitor substation online. And the development of Smart Grid makes the communication network message of substation’s process layer, bay level and station level become the primary mean of IED message interchange and share. The situation of intellectual equipment and communication network will affect the communication quality of the whole substation. Sending, receiving and communication network abnormity might result in serious accidents.Data transmission among Smart Substations mainly depend on fiber network communication, so it is able to use Digital Signal Analyzer to record the entire communication process, effectively monitor network message, record and analysis, which can detect fault in advance and provide basis for diagnosis and maintenance of accidents. Pre-test should be done before integrated with substation. This paper studies the IEC61850fiber digital signal analysis system and designs test system for related study items as well as imitate data transmitting, which could be used as analyzer analyzing and displaying network messages of substation. Through analyzing and testing each module’s context, it is able to finish the verification of Test Analyzing System. The major contents include:1. Analyze IEC61850standard deeply, and explain the standard’s technical features, realization process and application;2.Through analyzing the IEC61850protocol optical signal testing system functions, design a testing system of the overall structure, configuration and application analysis;3. Research the message of IEC61850standard, introduce test software which contains MFC, PACP formats;4. Complete the program of test software, realize simulation transmit-receive of sampling value which meets IEC61850standard, the analysis of offline data and display. The testing of analyzer function is finished;Through the research and testing of analyzer test system, complete analysis and diagnosis of monitoring data about intelligent substation and providing relevant data for other test devices, which effectively guarantees the healthy status of the whole substations and facilitates of Smart Grid. |
