摘要
配电网的电压质量直接影响用户电气设备的正常运行。电力系统故障,系统运行方式的改变,配电线路的规划设计不当,用户电气设备的功率因数、无功功率及有功功率的变化等因素都会导致配电网电压产生波动。通过对上述影响配电网电压质量的原因进行分析,找出提高配电网电压质量切实可行的方法。
The voltage quality in distribution network would affect directly normal operation of the utility＇ s electric equipment. Such factors as fault in power system, variation of operation mode, improper planning design of distribution line, variation of power factor, reactive and active power of the utility＇s electrical equipment can cause voltage fluctuation in distribution network. The feasible method on improving voltage quality in distribution network is found out by way of analyzing the reason which affects the voltage quality in above distribution network.
