摘要
本文针对多谐波源构成的多目标、非线性强耦合系统,从宏观层面上研究谐波源传导、输电线路传递、多谐波源叠加等耦合机理.为此,本文首先建立了多谐波源耦合模型;其次深入分析城市电网谐波耦合机理,多层次剖析谐波传导、谐波放大、谐波叠加等耦合因子及其特性.在此基础上,采用导纳矩阵对角化思路研究了多谐波源的解耦方式和解耦目标,为多谐波源的责任区分、谐波源治理提供清晰的思路.最后,通过应用案例及仿真验证了理论及算法的可行性.
Aiming at multi-objective, nonlinear and strong coupling system which is composed of the multi harmonicsources, the harmonic transmission and multi harmonic superposition coupling mechanism is studied in this paper form the macro level. Therefore, first of all, the city grid coupled harmonic source model is established through the language of Mathematics; Secondly, the coupling factors such as harmonic wave, harmonic amplification, harmonic superposition and their characteristics are analyzed in many levels. On this basis, the decoupling method and decoupling target of multi harmonic sources is also analyzed by the idea of using admittance matrix. Finally, the feasibility of the theory and algorithm is verified by simulation and experiment.
