摘　　要：针对配电网检修的对象选取主观性强、可靠性评估采用历史平均数据等问题,提出基于状态监测的配电网可靠性检修选择模型及算法。根据设备状态监测量与故障率的关系,建立了以检修前后系统平均停电频率、系统平均停电时间、系统缺电量的变化量最大为目标,以预算成本和人力资源为约束条件的多目标配电网可靠性检修选择模型,基于规格化法向约束方法高效准确获得完整且均匀分布的Pareto前沿,采用模糊选择策略确定最优折中解。对RBTS-BUS6系统的计算表明,所提出模型及算法能够有效求解配电网可靠性检修问题。In allusion to the subjective selection of maintenance objects and historical data based reliability assessment, a reliability-centered maintenance selection model for distribution network based on condition monitoring is put forward, and the solving algorithm is given. According to the quantitative relationship between condition monitoring variables of equipment and its failure rate, a multi-objective reliability-centered maintenance selection model, which maximizes variation of system average interruption frequency, system average interruption duration and expected energy not supplied with the constraints of budgets and human resources, is established; the normalized normal constraint method is employed to solve the model, and obtains fast and precisely Pareto frontier where the distribution of optimal solutions becomes uniform; the fuzzy selection strategy is used to determine the best compromise solution. The numerical results of RBTS-BUS6 system validate the effectiveness of the proposed reliability-centered maintenance selection model and the solving algorithm.
