摘　　要：研究了配电网的无功优化方法,以有功网损最小为目标,建立了无功优化的数学模型。针对配电网呈辐射状、节点多、计算量大的特点,提出了先用最大节约网损的算法找出待补偿的节点,再结合混沌的遍历性和粒子群的快速性等优点,采用混沌粒子群算法求解补偿容量的配电网无功优化方法。以一个实际的配电系统为算例,初步验证了所提算法的有效性。The reactive power optimization of distribution system is researched. Taking the minimized sum of electrical energy loss for objective function, a model for reactive power compensation is established. Contraposing to the feature of distribution systems, radial system and numerous nodes, the methods are presented that firstly uses a new algorithm to locate the nodes to be compensated, and then combines with Chaos and PSO, applies chaos particle swarm optimization to calculate capacitors size of locations. The effectiveness of the presented algorithm is verified by the results of calculation examples.
