| With the development of technology, some with high-power electronic switchingdevices and microprocessor-based controller modern electrical equipment for powerquality requirements are high, they are extremely sensitive to electromagneticinterference, and with users improve power quality awareness, more and more users tothe electricity sector for the quality of power requirements, in addition, will bringpower quality deterioration such as cause relay malfunction, adding additional loss andother issues, and power companies The need for improved operational efficiency, butalso to seek new ways to improve power quality.Power quality monitoring as a key power quality monitoring plays an importantrole in the operation and management and technical supervision system, but also anecessary condition to ensure good quality of power supply system. Powerful buildpower quality monitoring network, enabling centralized management of power qualityindicators, comprehensive tracking process systems running power quality indexchanges, monitoring power quality sources for running the power grid transientphenomenon and various fault case basis to provide analysis and further createconditions for improving the overall power quality grid security system for safe andeconomic operation of electrical equipment and a variety of electrical equipment,improve power system stability, with significant economic and social benefits.According to the monitoring line selection, the harmonic source user and systembus substation outlet installed power quality monitoring unit, the power qualitymonitoring stations. While establishing the appropriate power supply bureau inKaiping power quality monitoring center management, to communicate throughthe officeLANandsubstationpowerqualitymonitoringunit, consisting of power qualitymonitoring systems. In order to achieve overall system online monitoring andmanagement of field data by monitoring centers, sharing.In this paper, first made a brief introduction of power quality monitoring, powerquality problems of described; then to analyze power quality Kaiping, use the mainpower quality monitoring system, distribution network voltage data analysis, to graspeach line of power quality situation. |
