摘　　要：根据西南地区某省电网公司通报的水电机组跳闸和非计划停运等资料,对水电机组发生跳闸和非计划的停运次数、停运时长、故障原因等数据进行统计分析,从中找出对机组发供电设备可靠性影响较大的风险因素,进而掌握生产运行、设备检修维护过程中的薄弱环节,制定针对性的预防措施,为今后强化水电机组运维管理提供依据和参考。Based on the information on the trips and unplanned shutdowns of hydroelectric units reported by a certain provincial power grid company in the southwest region of China,statistical analysis is conducted on the number of trips and unplanned shutdowns,duration o£shutdowns,and causes o£equipment malfunction o£hydroelectric units.From this,risk factors that have a significant impact on the reliability of power generation and supply equipment are identified,and weak links in production operation and equipment maintenance processes are grasped.Targeted preventive measures are formulated based on these findings,serving as a basis and reference for strengthening the operation and maintenance management of hydropower units in the future.
