Abstract

Unlike previous research which didn't consider opportunistic maintenance between dependent power equipment in power system, opportunistic maintenance strategy is modeled and the impact of opportunistic maintenance strategy on maintenance scheduling of transmission bays is investigated in this paper. According to the economic dependence within a transmission bay, the concept of selective opportunistic maintenance is proposed. In the selective opportunistic maintenance problem, when the equipment in a transmission bay fails, decisions have to be made on whether other equipment is preventively maintained. Firstly, in order to determine the optimal inspection rates and opportunistic maintenance strategy for power equipment, the availability function of the transmission bay is derived. And then, expected system outage cost incurred from equipment maintenance or failure are quantified. Finally, the system maintenance scheduling model is given, with the goal of minimizing the system outage cost. Case studies on typical transmission bays reveal feasibility of the proposed model.

考虑选择性机会性维修策略的传动箱维修计划

不同于以往的研究没有考虑电力系统中相互依赖的电力设备之间的机会检修，本文建立了机会检修策略模型，研究了机会检修策略对输电机组检修计划的影响。根据传动舱内的经济依赖性，提出了选择性机会检修的概念。在选择性机会性维护问题中，当一个传动舱内的设备发生故障时，必须决定是否对其他设备进行预防性维护。首先，为了确定电力设备的最优检查率和机会检修策略，推导了传动箱的可用性函数。然后，对设备维护或故障引起的预期系统停机成本进行量化。最后，给出了以系统停机成本最小为目标的系统维护调度模型。对典型传动箱的实例分析表明了该模型的可行性。
