摘要
提出基于可靠度的输变电设备状态检修优化决策模型。首先,讨论计及检修策略的设备可靠度表达,并基于此对前瞻时间内设备可用度进行求解,从而在给定设备检修策略的前提下,对电网整体的故障风险和检修风险进行量化,最后,以电网总风险最小为目标,计及状态检修的约束条件,形成电网状态检修的数学模型,并采用遗传算法进行求解,通过IEEERTS79系统算例分析表明模型的可行性、有效性。
A methodology for condition-based equipment maintenance optimization is presented based on equipment reliability. Firstly,equipment reliability expression is given considering maintenance strategy during the maintenance scheduling period. Then, equipment instantaneous availability function is obtained.Maintenance strategy, power system failure risk and maintenance risk are calculated.Finally,with constraints of the maintenance taken into account,system maintenance model which is solved by genetic algorithm is established to minimize total power system risk.The IEEE-RTS79 test system is used to verify feasibility and effectiveness of the proposed model.
