多谐波源的谐波电流耦合及解耦策略研究
Research on harmonic current coupling and decoupling strategy of multi-harmonic sources
摘要
Abstract
According to the adverse effects of the multi-harmonic coupling on the power grid, first of all, this paper established the coupling admittance model of multi-harmonic sources, and then, combined with the model for harmonic analysis of transmission and coupling factor analysis. Secondly, according to the coupling relationship between harmonic sources, the decoupling method is proposed in this paper based on SVD (singular value decomposition), which is used to decouple the coupling factor matrix, thus weakening the interaction between harmonic sources. Finally, the decoupling strategy is applied in harmonic transmission and harmonic responsibility partitioning, and the MATLAB / Simulink simulation is carried out through the examples and IEEE 13 node system. The results show that the decoupling algorithm can be used for guidance of harmonic control device allocation optimization and gets more precise responsibility distinguish results, which verifies the validity and feasibility of the theory and algorithm.关键词
