| 摘 要： | 给出了无源滤波装置参数设计的建模方法。根据Thevenin定理与Norton定理对无源滤波装置在基波与谐波下的工作状态分别建模分析。基于数值方法，分析了电网电抗及电网频率摄动时流入滤波装置各通道基波电流的变化过程。通过符号计算，给出了流入电网及各滤波通道谐波电流的表达式。数值分析与现场实测结果表明，应用该文所给方法设计的滤波装置后进入电网的谐波符合国家GB／T-14549-93标准，功率因数由原来的0．82提高到0．94。

| Abstract: | A modeling method of designing parameter of passive power device is presented. The work conditions of passive power device were modeled and analyzed according to Thevenin theorem and Norton theorem, respectively. Under the perturbation of source impedance and frequency of the power system, changes in fundamental current of inject into every filter of passive power device was analyzed based on numerical method. Expressions of harmonic current of inject into every filter of passive power device were given through character calculation. The numerical analysis and practice measure show that, the harmonic currents of inject into power system accord with national criterion GB/T-14549-93 and its power factor is increased to 0.94 from before 0.82. |
