摘要

供配电系统一旦出现三相不平衡问题，就会对线路、变压器和电力设备造成损坏。分析了三相不平衡问题产生的原因和危害，总结了三相不平衡问题的管理方法。最后，决定采用有源电力滤波器对三相不平衡负载进行补偿。并通过MATLAB Simulink仿真软件库对三相不平衡状态下的无功补偿和谐波控制进行仿真，从示波器上得到三相电压波形图和电压幅值，根据结果进行分析。

Analysis and Treatment of Three-Phase Unbalance Problem

Once the three-phase unbalanced problem occurs in the power supply and distribution system, it will cause damage to the lines, transformers and power equipment. This paper analyzes the causes and harms of the three-phase imbalance problem and summarizes the management methods of the three-phase imbalance problem. Finally, it is decided to use the active power filter to compensate the three - phase unbalanced load. And through the simulation software of MATLAB Simulink library of three-phase unbalanced state of reactive power compensation and harmonic control simulation, three-phase voltage from the oscilloscope waveform diagram and the voltage amplitude, according to the result analysis.
