摘要
无源滤波器组的参数设计通常均针对系统单一工况(通常为最大工况)进行。当系统运行在其他工况时,有可能无论退出哪一组滤波器的运行均无法同时满足系统的无功补偿和谐波治理要求。为此基于系统的3种典型工况(最大、平均和最小工况)对无源滤波器组进行优化设计,确定合理参数,以在最小的投资费用下达到谐波治理与无功补偿的最优匹配。算例结果验证了该方法的可行性。
Parameters of passive filter （PF） group are usually designed according to single operating mode, in general the maximum operation mode. When power system is being operated in other operation mode, it is impossible to meet the requirement of power system in reactive power compensation and harmonic elimination simultaneously when whichever filter group is out of service. For this reason, based on three kinds of typical operation mode, namely the maximum, average and minimum mode, the optimization design of PF group is performed and reasonable parameters are determined to achieve the optimal matching between harmonic elimination and reactive power compensation by the lowest investment cost. The feasibility of the proposed method is verified by simulation results.
