Application and Analysis of the Power Quality Online Monitoring System in Guangzhou Power Grid

摘要

In this paper it is introduced about power quality on-line monitoring system operation structure and main function of Guangzhou power grid. Both harmonic voltage overproof reasons of 220kV CongHua substation 10kV bus bar and power system short-term voltage flicker accidents of 220kV BeiShi B line caused by switch fault are analyzed, which base on large data recorded after the application of power quality monitoring system and combine with power equipment running status. Operation status shows power quality on-line monitoring system play some important roles in mastering the real-time power quality of the power grid for management department and supplying high power quality services for the user.
