摘　　要：为有预见性地防御直流偏磁危害,在新建直流接地极初期应对直流接地极进行优化选址。考虑母线电压、发电机功率以及变压器因直流电流额外消耗的无功功率等参数,提出了基于人工蜂群算法的直流接地极优化选址方法,并量化了直流电流对交流电网的影响,最终通过IEEE 118节点及某实际电网两个工程算例验证了人工蜂群优化选址方法的可行性。研究结果为直流接地极优化选址、防御直流偏磁危害、降低直流电流对交流系统的影响提供了可能。In order to defense DC bias harm foreseeably,it＇s necessary to optimize location at the beginning of constructing a new DC grounding electrode.This paper puts forward the location optimization method of grounding electrode based on artificial colony algorithm and quantifies the impact of DC current on AC power grid by considering the bus voltage,generator power and the extra consumption of reactive power of transformer caused by direct current.Finally,the feasibility of artificial colony algorithm for location optimization is verified by IEEE 118 node system and two engineering examples of a practical power network.The research results can be used to optimize DC grounding electrode location,defense DC bias harm and reduce the impact of DC current on AC power grid.
