摘　　要：三相负荷不平衡问题严重危害配电网的安全经济可靠运行。在此背景下,提出一种晶闸管无缝换相装置控制策略,实现三相负荷的的均衡分配。首先,建立基于无缝换相装置的配电台区三相负荷不平衡治理系统的数学模型;基于该数学模型,采用向量基因遗传算法求解实现三相不平衡负荷治理,获得台区负载的最佳相别分配方案,通过仿真验证算法可行性;最后,在低压配电台区安装无缝换相装置,通过实验验证了该控制策略的正确性和可行性。The three-phase load imbalance seriously influences the safety,economic and reliable operation of distribution network.On this background,a control strategy of the SCR is proposed in this paper.Firstly,on the basis of the seamless commutation device,a mathematic model of three-phase load imbalance treatment system in distribution network is established.Then,the vector-genetic algorithm is utiliazed to realize the three-phase load imbalance treatment and the optimal phase allocation scheme of the distribution area is obtained.Finally,the feasibility of the algorithm is verified by the simulation.The seamless commutation devices are installed in the low voltage distribution area and the experimental results validate the correctness and feasibility of the proposed control scheme.
