摘　　要：该文介绍一种利用功率电子调压器实现配电网络电压补偿的方法,并结合电力电子调压器的特点,给出一种基于功率电子调压器的配电网络电压补偿方法。首先,将电力电子调压设备等效为节点的功率注入模型,利用微粒群算法对当值节点的有功、无功进行优化,也就是节点注入额外的能量,然后利用额外的能量进行潮流计算,从而得到补偿电压和相角。通过对IEEE33节点等效模型的实例计算,表明该方法能显著降低电压损失,同时将功率优化和潮流计算相分离,可以降低计算复杂度,提高计算精度。In this paper,a method of using power electronic voltage regulator to realize voltage compensation of distribution network is introduced,and according to the characteristics of power electronic voltage regulator,a voltage compensation method of distribution network based on power electronic voltage regulator is presented.First of all,the power electronic voltage regulating equipment is equivalent to the power injection model of the node,and the particle swarm optimization algorithm is used to optimize the active and reactive power of the node,that is,the node injects additional energy,and then the extra energy is used to calculate the power flow.Thus the compensation voltage and phase angle are obtained.The calculation of the IEEE33 node equivalent model shows that this method can significantly reduce the voltage loss and,by separating the power optimization from the power flow calculation,can reduce the computational complexity and improve the computational accuracy.
