摘　　要：在实现碳达峰和碳中和目标的背景下,新能源电力系统的接入导致电网的不稳定性增加。在此情况下,抽水蓄能电站对于保障电力系统的安全稳定运行至关重要。然而,传统的检修方案已不适应新型电力系统对抽水蓄能机组的功能要求,检修计划和检修规律与当前电网负荷调整窗口期存在一定矛盾。为此,针对抽水蓄能电站的柔性检修项目决策,提出了一套包含状态评估、趋势预警和系统开发的技术方案。最终形成的项目决策模块建设方案可以综合评估柔性检修的必要性、等级、项目、工期等,有效提升了检修效率,并增强了抽水蓄能电站在新型电力系统中的可靠性和服务能力。该研究成果已成功应用于某电厂,为抽水蓄能电站的检修决策提供了科学合理的指导。In the context of achieving carbon peak and carbon neutrality goals,the integration of new energy power systems has led to increased instability of the power grid.In this case,the pumped-storage power stations are crucial for ensuring the safe and stable operation of the power system.However,the traditional maintenance plan is no longer suitable for the functional requirements of pumped-storage units in the new power system,and there is a certain contradiction between the maintenance plan and rules and the current load adjustment window period of the power grid.Therefore,a technical solution including state assessment,trend warning,and system development is proposed for the flexible maintenance project decision-making of pumped-storage power stations.The final project decision-making module construction plan can comprehensively evaluate the necessity,level,project and duration of flexible maintenance,effectively improve maintenance efficiency,and enhance the reliability and service capabilities of pumped-storage power stations in the new power system.The research results have been successfully applied to actual power plants,and provide scientific and reasonable guidance for maintenance decisions of pumped-storage power stations.
