摘要
介绍了应用于低压配电系统中的无功自动补偿控制策略。通过检测线路电压、无功功率、功率因数等变量,采用5区图控制原理,根据线路不同特性,细分了电压优先无功控制、电压控制、时间控制、电压时间控制、功率因数控制等5种不同的控制策略进行电容器投切,有效地维持了系统电压的水平。
This paper introduced reactive power automatic compensation control strategy used in low voltage power distribution system, by detecting the line voltage, reactive power, power factor and other variables, using five district map control principle, according to the different characteristics of the line, using five different control strategies such as voltage reactive power control priority, voltage control, time control, voltage time control, power factor control for capacitor switching, it can keep the voltage level effectively.
