供电电源系统电能质量稳定性监测方法
Monitoring Method for Power Quality Stability of Power Supply System
摘要
Abstract
Monitoring the power quality of power supply system is an effective method for ensuring the safe opera-tion of power system and user-side equipment.To ensure the power quality of power supply system,a monitoring method for its power quality stability is studied.Based on the Hilbert-Huang transform(HHT)algorithm,the harmonic frequency and amplitude of the power quality signal frame of power supply system are monitored,and the disturbance time ampli-tude and frequency of the power quality disturbance signal are detected,so as to realize the power quality stability of monitoring system.The frame loss rate,accuracy and transmission delay of the monitored power quality signals under different pressures(with different numbers of power quality signal frames)were tested by experiments,and results show that the proposed method can realize the monitoring of power quality.关键词
