Reactive power control system based on magnetically controlled reactor

为了改善电网无功功率不平衡导致的电网电压巨大波动、功率因数低落等问题,设计了一种基于磁阀式可控电抗器的无功控制系统。该系统采用多变量控制策略,通过控制电抗器的输出感性无功,实现功率因数控制、母线无功功率和母线电压的连续调整。试验结果表明,多变量控制策略能有效应用于系统目标参数控制,达到了预期的效果。

In order to solve problems of fluctuation of voltage and low power factor caused by imbalance of reactive power of power grid,a kind of reactive power control system based on magnetically controlled reactor was designed.The system uses multi-variable control strategy,and can accomplish regulation of power factor,reactive power as well as voltage of busbar by controlling output reactive power of magnetically controlled reactor.The experiment result proves that the multi-variable control strategy can be applied to target parameter control effectively,and achieves expectant effect.
