Research And Design Of Real-Time Power Quality Monitoring Instrument

With the rapid development of national economy and science technology,diverse kinds of industry production demand higher power quality. So detecting and analyzing power quality is very significant.The Research and the Analysis about the design of the Real-time Monitoring System for Power Quality are given in the paper.First, a review is introduced, which is about the cause of power quality, the measurement index of power quality and the research status at home and abroad.The detection principle of power quality's indexes are analyzed in detail. The implement methods of power quality's indexes digitalization are also analyzed and compared in paper. It gives the necessary theoretical basis for design of the power quality real-time monitoring system.An equipment of power quality real-time monitoring system is proposed and realized, based on the theoretical research and analysis mentioned above. Finally, the total test and analysis are given, according to the indexes of power quality real-time monitoring system. The test data, from actual measurement, proves that the algorithm methods are correct and reasonable.
