摘　　要：在对不平衡电流保护的电容器组中的故障电容器进行更换后,往往需要对电容器组进行重新调平,若调平方案不合适,则需要耗费大量人力物力。为了提高调平的效率,首先分析了不平衡电流的影响因素,结合实际工程需要,得出调平方案的优化目标;然后基于此目标设计了基于遗传算法的调平方法计算方案。结果表明应用遗传算法可以在保证调平效果的基础上,得到工程量较小的电容器装置调平方案,提高调平工作效率。After replacing the faulty capacitor in the capacitor bank for unbalanced current protection,it is often necessary to level the capacitor bank again.If the leveling scheme is not suitable,it will take a lot of manpower and material resources.For improving the leveling efficiency,the influencing factors of the unbalanced current are analyzed firstly,and the optimization objective of the leveling scheme in combination with the actual engineering needs.Then,the calculation scheme of the leveling method based on genetic algorithm is designed on the basis of this objective.The results show that application of the genetic algorithm can,on the basis of assuring the leveling effect,obtain the leveling scheme of capacitor device with less work and improve the working efficiency.
