摘　　要：顶盖排水系统是水电机组辅机系统之一,对水电厂安全运行起着重要作用,评估顶盖排水系统健康状态是保证机组安全运行的必要措施,运用层次分析法将顶盖排水系统分解为多个层次,结合数据挖掘提取表征系统健康状态的状态特征参数,并建立健康样本,运用AHP权重法赋权,构建基于健康基准值偏离程度的健康评估模型,实现水轮机顶盖排水系统健康状态评估,结合实际水电站顶盖排水系统实际运行数据,验证了该方法的有效性和可行性。The roof drainage system is one of the important auxiliary systems of hydropower units.It plays an important role in the safe opera⁃tion of hydropower plants.Evaluating the health status of the roof drainage system is a necessary measure to ensure the safe operation of the unit.The drainage system is decomposed into multiple levels,combined with data mining to extract the state characteristic indicators that characterize the health state of the system and establish health samples,use the AHP weight method to give weights and build a health assess⁃ment model based on the degree of deviation of the health reference value to accomplish the turbine roof drainage system.The health status as⁃sessment,combined with the actual operation data of the roof drainage system of the actual hydropower station,verifies the effectiveness and feasibility of the method.
