摘要
对于三相整流负载对电网产生的谐波影响,利用开关函数法分析了其各次谐波的幅值和相位,并与SIMULINK仿真结果相比较,为改善电网电流品质提供了有效工具。
In this paper, the harmonic influence of three-phase rectifier circuit on the electric network is analyzed, and the amplitude value and phase of each harmonic component is obtained by applying switching function. Compared with the SIMULINK result, it confirms that it can help to improve the quality of currency in the electric network.
