在对换相开关治理低压台区三相不平衡的有效性进行研究的基础上,提出了一种基于分析三相不平衡节点电气参数等数据以确定换相开关安装位置及优先级的方法。通过工程实际应用换相开关,验证得出换相开关能够缓解三相不平衡问题的结论。通过对应用换相开关的典型台区进行仿真分析,得出换相开关能够降低线损率的结论。

Based on the research of the effectiveness of phase-change switch in the treatment of three-phase imbalance in low voltage substation area,the new method is proposed to determine the installation location and priority of phase-change switches by analyzing the electrical parameters and other data of three-phase imbalance nodes.Through the practical application of phase-change switch in the project,the three-phase unbalance problem can be relieved.Through the simulation analysis of the typical substation area where the phase-change switch is applied,the line loss rate can be decreased.
