为保障水电厂安全运行,根据水电厂设备设施构成要素,系统分析其风险,建立涵盖水轮机及其辅助设备、发电机及其辅助设备、计算机监控系统及自动装置、电气一次设备、电气二次设备、水工建筑物及金属结构、机具与防护设施等因素在内的评价指标体系。采用欧氏距离定义样本差异,标准化处理属性特征值,通过聚类迭代,开发水电厂设备设施风险的动态分级方法。研究结果表明:水电厂设备设施故障风险在每年的第2,3季度明显大于第1,4季度,并且随着时间推移,各季度设备设施故障风险同比有增加的趋势,风险分级结果与设备设施故障的变化趋势基本吻合。
In order to ensure the safe operation of hydropower plants, according to the elements of hydropower plant equipment and facilities, the risks are analyzed systematically, and the hydropower plants and their auxiliary equipment, generators and their auxiliary equipment, computer monitoring systems and automatic devices, electrical primary equipment, electrical secondary equipment , Hydraulic structures and metal structures, machinery and protective equipment and other factors, including the evaluation index system. The Euclidean distance is used to define the sample differences and standardize the attribute eigenvalues. Through the clustering iteration, a dynamic grading method is developed for plant facility risks of hydropower plants. The results show that the risk of equipment and facilities failures in hydropower plants is significantly greater than that of the first and the third quarters of each year in the first and the third quarters of each year, and as time goes on, the risk of equipment and facilities failures in each quarter tends to increase year-on-year. The risk rating results, The trend of failure basically agrees.
