【摘要】：基于有效役龄和故障率函数对电力设备的多级检修方式进行建模,并从可靠性成本/效益角度对发输电系统多级计划检修周期进行协调优化研究。计及故障率随时间的增长效应,以电力设备检修导则中的计划检修等级定义为参照,建立考虑A级完全检修、C级不完全检修条件下的电力设备故障率模型;在此基础上建立系统可靠性指标、系统检修成本、停电成本、C级计划检修周期、A/C级检修周期比率之间的解析表达式。针对以系统检修成本与系统停电成本之和最小为目标的大规模混合整数非线性规划问题,提出融合灵敏度分析和前向/后向差分思想的电网多级计划检修协调优化启发式迭代算法。探讨检修恢复因子变化对电网计划检修优化的影响。RBTS、IEEE-RTS79系统验证了所提算法的有效性。
[Abstract]:Based on the effective service life and failure rate function, the multistage maintenance mode of power equipment is modeled, and the coordinated optimization of the multistage planned maintenance cycle of power generation and transmission system is carried out from the point of view of reliability cost / benefit. Considering the increasing effect of failure rate with time, taking the definition of planned maintenance grade in maintenance guidelines of power equipment as the reference, the failure rate model of power equipment considering the condition of class A complete overhaul and class C incomplete maintenance is established. On this basis, the analytical expressions of system reliability index, system maintenance cost, blackout cost and C class planned maintenance cycle ratio are established. Aiming at the problem of large-scale mixed integer nonlinear programming with the goal of minimizing the cost of system maintenance and outage, A heuristic iterative algorithm for coordination optimization of multilevel planning and maintenance in power network is proposed, which combines sensitivity analysis with forward / backward difference. This paper discusses the effect of the change of maintenance recovery factor on the optimization of grid maintenance. The RBTS IEEE-RTS79 system verifies the effectiveness of the proposed algorithm.
