新一代智能变电站电子式电压互感器异常分析
Anomalies analysis on electronic voltage transformer in new generation smart substation
摘要
Abstract
This paper introduces abnormal conditions of electronic voltage transformers among start-up process for new generation smart substation in Anhui.By analyzing the recorded waveform data on site, it is speculated that there are anomalies in voltage converters.Comparing the new waveforms with old ones of voltage converters from the waveform, the speculation is demonstrated.With the spectral analysis of waveforms using S-transform, it is further determined that poor performance of voltage converter directly leads to the above anomalies.Finally, some reform measures are proposed to prevent this kind of anomalies.关键词
