厂站电能量远方终端电压采集异常故障分析

Analysis of Abnormal Faults of Remote Terminal Voltage Acquisition of Power Station

针对广西某电厂的厂站电能量远方终端电压显示异常故障,搭建试验室模拟测试平台,通过模拟不同相别的电压组合场景对故障现象进行复现。基于故障现象,对故障厂站终端抄读电能表电压瞬时量的流程和用户采集参数的配置文件进行分析,查出故障原因为该文件参数配置异常,并提出了相应整改措施和建议。

In view of the abnormal voltage display of the electric energy remote terminal of a factory station in Guangxi,the laboratory simulation test platform was built.Through the simulation of different phase voltage combination scenes,the fault phenomenon were reappeared.The flow of the voltage instantaneous quantity of the power meter of the fault terminal and the user acquisition parameter were analyzed based on the fault phenomenon.The cause of the malfunction was found to be abnormal configuration of the file parameters.The corresponding treatment measures and suggestions were proposed.
