| The Power Quality Monitor System technology is researched; the existing power quality monitoring method and the on line monitoring method are comparative analyzed. The system structure, data structure, monitoring contents and analyzing platform etc. of the power quality on line monitor system are fully analyzed. For the Olympic important power customer and substations, one networking, information, and standard grid power quality monitor system is built, which has uniform and opening monitoring and management platform. The system is a high efficiency power quality management system, which can all-whether monitor the grid power quality indicator. The application of power quality on line monitor system can bring manufacture benefit and social economic benefit. |
