摘　　要：分析了阻抗匹配平衡变压器在阻抗匹配条件下的三相-两相对称变换关系,利用对称分量法,计算了阻抗匹配平衡变压器对电力系统的负序影响,在Matlab/simulink环境中建立阻抗匹配平衡变压器的模型并仿真,仿真结果直观清晰地阐明了阻抗匹配平衡变压器的运行特性。The three-phase to two-phase symmetrical transformation of balance transformer is analyzed under impedance matching condition. Using symmetrical components method,negative phase sequence influence on power system is calculated. Finally, based on the previous theory analysis, an simulation model of balance transformer is constructed in Simulink and characteristic Simulation is made. The simulation result is very vusual and easy to understand.
