摘要
以等风险度原则为基础,以各检修时段风险度方差最小为目标函数,建立了发电机组检修计划模型,提出了最小累积风险度法。该启发式求解方法采用半不变量法结合Gram-Charlier级数展开法求解系统的风险度,通过寻找检修区间内累积风险度最小的区间确定待检修机组的检修位置。以IEEE-RTS系统为算例的机组检修计划结果验证了最小累积风险度法的有效性。
Based on equal risk algorithm principle,the paper establishes generating unit maintenance scheduling model using object function of maintenance period risk algorithm minimum variance,and proposes minimum cumulative risk algorithm.The algorithm adopts cumulant and Gram-Charlier series expansion method to solve risk algorithm of system,as well as determines maintenance position through searching minimum cumulative risk range in maintenance region.The unit maintenance scheduling using IEEE-RTS as algorithm example has proofed the effectiveness of minimum cumulative risk algorithm.
