摘　　要：针对交流滤波器配置容量按照换流站无功消耗计算公式整定存在一定偏差的问题,提出一种基于反函数抛物线插值确定交流滤波器配置容量的方法。该方法借助潮流计算确定3组交流滤波器配置容量和交直流系统无功交换量数据,并根据交直流系统要求的无功交换量,采用反函数抛物线插值确定所需交流滤波器配置容量。与目前工程上采用的反复试探法和线性插值法相比,所提方法只需3次潮流计算,耗时少且精度较高。计算验证了该方法的可行性。Aimed at the problem that there exists deviation in the AC filter capacity configuration according to the reactive power consumption by a converter station determined by the corresponding calculation formula,a method is proposed to determine the configuring capacity of AC filter based on inverse function parabolic interpolation,which determines three groups of data about the AC filter configuring capacity and the reactive power exchange required by the AC/DC system by means of power flow calculation.According to the reactive power exchange required by the AC/DC system,the inverse function parabolic interpolation is used to determine the required AC filter configuring capacity.Compared with the trial-and-error method and linear interpolation method used in engineering at present,the proposed method only needs three times of power flow calculation,takes less time,and has a higher precision.In addition,its feasibility is verified by calculation results.
