New Balancing Algorithm for Double Star Capacitor Bank Based on Targeting Function

提出了一种基于靶向的双星形电容器组电容值调平衡新算法。首先通过建立靶向函数确定每轮调平衡的靶心点,然后利用打靶函数进行全覆盖的精确打靶处理,最后按照预先设置的标准不平衡率计算出一组最优调平衡策略,从而实现电容器组调平衡的目的。该算法已经形成了实用化程序并进行了实际应用,取得了良好效果,验证了本算法的有效性和实用价值。该算法具有计算量小、收敛速度快、置换策略最优化的优点,具有良好的应用前景和推广价值。

A new balancing algorithm for double star capacitor bank based on targeting function is proposed in this paper.Firstly,the target center-point is determined by the targeting function,and then the shooting function is used to perform full-coverage and accurate shoot-processing in each round.According to the preset standard unbalance ratio,an optimal set of balancing strategies is finally calculated to achieve the purpose of balance of the double star capacitor bank.Practical program based on the balancing algorithm is formed and applied to practice,which achieves good results and the effectiveness and practical value of the algorithm is verified.This algorithm has the advantages of small amount of calculation,fast convergence and optimal substitution strategy,and has good application prospect and promotion value.
