摘　　要：针对电力系统负荷预测误差、机组随机停运及风电场出力波动性问题,采用半不变量法求解系统风险度指标,安排电力系统机组检修计划。以各检修时段风险度方差最小为目标函数,建立了含风电场的电力系统发电机组检修计划模型,给出了基于半不变量法的机组检修计划的计算步骤,并以国内某实际电网为例进行了验证。结果表明,该方法能充分考虑电力系统的不确定性,降低了负荷预测误差及风电场出力波动对机组检修计划带来的影响。According to the uncertainty of load forecasting, random outage of generator and intermitteney of wind power, the heuristic algorithm of generator maintenance scheduling based on minimum cumulative risk is proposed. A novel generator maintenance scheduling model based on equivalent risk principle is presented, which takes the minimum of risk standard variance of all the maintenance period as planning objective. The implementation of generator maintenance scheduling is given on the basis of semi-invariant method. The numerical results obtained from ease studies of an actual China Power Grid, validate the correctness and effectiveness of the proposed new model and algorithm.
