respectively each monitoring point (as user's bus), each computer workstation is arranged on respectively to province company electric energy quality monitoring center, city company electric energy quality monitoring center, harmonic wave specific responsibility center, information center etc.The specific works process is as follows: the power quality data of each voltage transmitter, each current transducer, each frequency transmitter, each power transducer, each each monitoring point of power factor transmitter Real-time Collection (comprising voltage data, current data, frequency data, power data, power factor data etc.), and the power quality data that will collect separately by Digital Data Net is sent to data server in real time.Data server carries out real-time collecting to the power quality data received, and by Digital Data Net, the power quality data of collecting is sent to the WEB server in real time.The WEB server carries out Real-Time Sharing to the power quality data received, and by Digital Data Net, the power quality data after sharing is sent to each computer workstation in real time.Each computer workstation represents in real time to the power quality data received, and generates in real time statistic analysis result (comprising form, curve, pie chart, rod figure etc.) according to the power quality data received.The staff of province company electric energy quality monitoring center, city company electric energy quality monitoring center, harmonic wave specific responsibility center, information center etc. is by real time inspection power quality data and statistic analysis result, can find in time the power quality problem of each monitoring point, and take in time corresponding measure to improve the quality of power supply.In this process, the staff of province company electric energy quality monitoring center, city company electric energy quality monitoring center, harmonic wave specific responsibility center, information center etc. can arrange and revise by computer workstation the running parameter of each voltage transmitter, each current transducer, each frequency transmitter, each power transducer, each power factor transmitter in real time, the power quality data that also can collect by computer workstation real-time query data server, the power quality data after also can sharing by computer workstation real-time query WEB server.Based on said process, with existing equipment for monitoring power quality, compare, remote power quality online monitoring system based on wide area network of the present invention has following advantage: one, remote power quality online monitoring system based on wide area network of the present invention adopts Digital Data Net as data transfer platform,
