Abstract :
In order to prevent coal power system fault for safety production, a novel power quality real time monitor is researched in this paper. According to the coal power system special characteristics and safety production standard, the harmonic of the coal power system is analyzed first based on the wavelet theory, and then the monitoring system is designed with ARM LPC2132 as the client computer to fulfill the common power parameter data acquisition. The whole monitoring system is composed of the signal transform module, data processing module, communication module, host computer interfaces and their function modules. The system software is designed with the platform of LabWindowns/CVI. The research result shows that the power quality monitor can detect the harmonic states in real time.
