Abstract:

建立了以可靠性为中心的配电线路检修(reliabilitycenteredmaintenance,RCM)策略优化计算模型。该模型的目标是使系统可靠性达到最高,其约束条件为总维修费用不超出预算。RCM优化计算模型是0-1规划问题,因此采用分支界限法对其进行求解,而分支界限法中松弛子问题则采用内点法进行求解。分支界限法能够得到混合优化问题的全局最优解,而内点法的突出优点是全局收敛性好。通过含有6个子系统的辐射型配电网对提出的RCM优化检修算法进行仿真研究,分析了不同检修策略对系统可靠性的影响,并计算出以可靠性为中心的最优检修方案,与其他方案进行比较表明了RCM优化计算模型的可行性。
