摘　　要：电能质量监测是保障电力系统安全稳定运行的重要手段。受成本与技术限制,现有电能质量监测装置的配置往往难以满足实际需求。针对这一问题,提出了一种基于状态估计的电能质量监测点优化配置方法,并设计了一种改进的智能优化算法用于求解。在此基础上,进一步考虑了实际电网的拓扑结构与运行约束,提出了一套切实可行的监测点优化配置策略。通过IEEE标准测试系统和实际电网案例的仿真分析,验证了所提方法的有效性和优越性。Power quality monitoring is an important means to ensure the safe and stable operation of the power system.Due to cost and technical constraints,existing monitoring device configurations often fail to meet practical needs.To address this issue,this paper proposes a method for optimizing the configuration of power quality moni-toring points based on state estimation and designs an improved intelligent optimization algorithm to solve the problem.Furthermore,considering the topology and operational constraints of the actual power grid,a feasible strategy for optimizing the placement of monitoring points is presented.The effectiveness and superiority of the proposed method are verified through simulation analysis using both the IEEE standard test system and real-world powergrid cases.
