同步相量测量单元静动态自动测试系统的研究与开发

摘要

同步相量测量单元(phasor measurement unit,PMU)的量测性能是其能否更好地服务于电力系统的关键,在对 PMU静动态测试方案、性能评估方法研究的基础上,基于 MATLAB 软件与 OMICRON 测试仪开发了PMU静动态自动测试系统,主要功能模块包括信号发生模块、相量提取模板、误差分析模块等。采用所开发的PMU静动态自动测试系统对国内主流厂家的 PMU装置进行了测试,测试结果验证了所开发系统的正确性及准确性。该系统具有较高的实用性,可对入网 PMU装置进行检测,严把质量关,确保电力系统的安全稳定运行。%Measuration performance of phasor measurement unit is key to well serve power system. Based on studying static and dynamic testing scheme of PMU and performance evaluation method,a kind of static and dynamic automatic testing sys-tem of PMU was developed on account of MATLAB software and OMICRON tester of which main functional modules in-cluded signal generation module,phase extraction module and error analysis module,and so on. The developed testing sys-tem was used for testing PMU devices of main manufacturers in domestic and results verified validity and accuracy of the sys-tem. Meanwhile,this system was of high practicability to detect access PMU devices,strictly control quality and ensure safe and stable operation of the power system.
