| 摘 要： | 电能质量(PQ)因为不同的PQ信号产生了多种分析技术,使得整合多种电能质量监控难度较大。为了解决这个问题,利用prony的PQ分析建立电能质量监控系统,可便捷地分析和检测各类PQ干扰,如基频偏差、谐波、相间谐波、电压波动以及PQ事件。目前,该监控系统已在南方电网中实施应用。

| Abstract: | Power quality(PQ)is difficult to integrate many kinds of power quality monitoring because of many kinds of analysis technology produced by different PQ signals.In order to solve this problem,the PQ monitoring system based on Prony’s PQ analysis can be used to analyze and detect all kinds of PQ interferences,such as fundamental frequency deviation,harmonic,inter phase harmonic,voltage fluctuation and PQ events.At present,the monitoring system has been applied in China Southern Power Grid. |
