摘　　要：由于常规继电保护方法不能有效提升电网运行状态,导致保护可靠性低、保护范围小,因此研究了基于自适应粒子群的配电网继电保护定值多目标优化方法。通过设计保护动作判据,配置保护采样信息完整传输的联动装置和应用自适应粒子群算法优化参数来进行继电保护。实验结果表明,在遇到继电故障时,采用自适应粒子优化算法计算出的电流保护整体动作时间最短,验证了所提出电网继电保护定值多目标优化保护方法的有效性。Because the conventional relay protection methods can not effectively improve the operation state of the power grid,resulting in low reliability and small protection range,a multi-objective optimization method for relay protection settings of distribution network based on adaptive particle swarm optimization is studied.The relay protection is carried out by designing protection action criteria,configuring the linkage device for complete transmission of protection sampling information and applying adaptive particle swarm optimization algorithm to optimize parameters.The experimental results show that the overall operation time of current protection calculated by the adaptive particle optimization algorithm is the shortest when encountering relay faults,the effectiveness of the proposed multi-objective optimization protection method for power network relay protection setting is verified.
