摘要/Abstract

摘要： 由于不同频次的谐波具有不同的相序特性，提出计及谐波相序特性的配电网谐波潮流改进算法。首先分析各频次谐波的相序特性，然后推导变压器的谐波相序模型，综合考虑变压器联结方式、联结组别和中性点接地阻抗等对谐波潮流分析的影响；并讨论其他元件的谐波相序模型。在此基础上，实现MATLAB程序化的分相序谐波潮流分析。最后，以IEEE33节点系统和某个含光伏电站的实际配电网系统为例，通过计算并与不计及相序特性的潮流计算结果及PSCAD的仿真结果进行对比，证明了所提方法的有效性和准确性。

Abstract: As different order harmonics have different phase sequence characteristics, this paper proposes an improved calculation method of harmonic power flow for distribution network. Firstly, we analyze the phase sequence characteristics of harmonics. Next, we deduce the transformer models under different harmonic phase sequence with taking the impacts of transformers winding connection modes, connection set and neutral point grounding impedance on harmonic power flow into account; and discuss the calculation model of other electrical elements of distribution system with considering phase sequence. On this basis, the harmonic power flow with different phase sequences in MATLAB we analyzed. Finally, taking the IEEE 33-bus system and a practical distribution network including photovoltaic power station as examples, the power flow with or without considering phase sequence characteristics was calculated and the results were compared with the simulation results in PSCAD, which verify the feasibility and correctness of the proposed method.

Key words: harmonic power flow, phase sequence characteristics, transformer, distribution network
