摘要
针对配电线路谐波电压放大问题,提出了含多个有源滤波器的配电线路谐波补偿优化调度方法。利用传输线理论分析了配电线路谐波电压放大现象,给出了多APF谐波补偿控制方法,建立了谐波治理优化调度模型,利用单目标遗传算法对逆变器谐波补偿参数进行优化。仿真结果表明,采用本文提出的优化调度方法,各节点谐波电压畸变均小于给定参考值,谐波补偿效果良好。
An optimization dispatch method for harmonic compensation in distribution feeders using multiple APFs is proposed to suppress harmonic voltage propagation. The phenomenon of harmonic voltage propagation along distribution feeder is analyzed by using the transmission line theory, and a control strategy for APF-based harmonic compensation is provided. An optimization dispatch model of harmonic compensation is established and the single objective genetic algorithm is used to optimize the harmonic compensation parameters of inverters. The simulation results show that the proposed algorithm can optimize the harmonic compensation parameters and reduce the total harmonic distortion of node voltages to rated values.
