| 摘 要： | 从理论上推导出电力系统中的非线性负荷在吸收系统基波功率的同时向系统发出谐波,从而成为系统的谐波源。并从功率方向着手,根据非线性负荷的不同作用机理建立不同的仿真模型分别验证了两种不同类型的非线性负荷谐波功率流向。实验结果表明,非线性负荷使系统电压、电流发生畸变,向系统发出谐波功率,从而验证了理论分析的正确性。

| Abstract: | In theory, non-linear load absorbs fundamental power from the power system, and injects harmonic power into the system as the harmonic source of the power system. From the view of power direction, this paper validates harmonic power directions of two kinds of non-linear load through respective models according to different function mechanisms. Test results show that non-linear load distorts system voltage and current and injects harmonic power into system, which proves the correctness of theoretical analysis. |
