摘　　要：检修计划编制过程中需要对设定检修方式下的系统运行状态进行安全评估,而目前检修计划编制缺乏必要的安全分析手段,过度依赖经验,难以适应大电网运行控制需要。提出基于母线负荷供应充裕度和等效发电容量损失指标的检修计划评估与安全辅助方法。利用网络拓扑灵敏度分析技术计算满足静态安全约束的母线负荷供应充裕度和等效发电容量损失,并根据该指标评估检修计划的安全性。该方法已在某区域电网检修计划优化管理系统中得到应用,结果表明该方法能够为计划编制人员提供指导性意见。In light of the current status of outage schedule based mostly on experience, security evaluation and optimization method of outage schedule based on bus load supply adequacy （LSA） and equivalent generation capacity loss （EGCL） is proposed with practical engineering computation method studied in detail. Besides, quantization security evaluation and optimization of outage schedule is implemented. By the results of sensitivity analysis based on the net model topology, the load supply adequacy （LSA） and equivalent generation capacity loss （EGCL） are calculated. This method is instructive for the outage schedule and has been applied in integrative optimization and management of outage schedule. The feasibility of this method is proved by engineering application.
