Abstract
In order to evaluate power quality more accurately, this paper presents a three-layer distributed online power quality monitoring system (PQMS), which uses the General Packet Radio Service (GPRS) wireless network as its communication channel. This PQMS consists of three parts: the power quality monitor (PQM), the monitoring software (MS) in upper computer and the web platform (WP). The PQM which is designed on the structure of DSP (Digital Signal Processor) + CPLD (Complex Programmable Logic Device) ensures the realtime and precise monitoring. Then the MS collects and analyzes the monitoring data. At the same time, GPRS network provides the communication channel for PQM and MS. The WP provides the monitoring data and the analysis results through internet, and supervisors can monitor and manage the power quality from a long distance. The detail design and its realization of each part are explained. Precision test of the PQM and field monitoring results with the PQMS are also discussed.
