摘　　要：随着地区电网的用电负荷不断增加,电网经常出现超计划用电或设备重载运行情况。在分析负荷电压特性的基础上,建立负荷的ZIP模型,寻找变电站有功负荷和负荷母线电压之间的变化规律,通过投切电容或调节变压器档位的方法调节电压,最终达到减载的目的。现场运行情况表明,本文提出的方法是有效的,可以通过调节电压而不切除负荷的方法实现减载,保证了供电质量。Along with the power load steady increase in regional power network,it often happens that die power grid runs beyond its schedule or the power device works beyond its safety restriction.Based on the analysis of voltage characteristics,ZIP model is set up.A method of soft load shedding is given by studying the relation between load real active power and its corresponding voltage.The field running results show that this method is effective,can realize load shedding through regulating voltage without load shedding.
