锦屏二级水电站避沙运行方式风险分析及管控措施研究

Research on Risk Analysis and Control Measures of Sediment Avoidance Operation Mode of Jinping-ⅡHydropower Station

在库区水流泥沙含量较高时,锦屏二级水电站需采取避沙运行方式,以降低泥沙对机组运行的不利影响。但避沙运行期间的特殊工况也将对电站的安全稳定运行提出严峻考验,故针对锦屏二级水电站的避沙运行方式进行了风险分析,最后提出的对应管控措施可有效应对电站避沙运行过程中可能产生的各种风险。

When the sediment content in the reservoir area is high,Jinping-ⅡHydropower Station needs to adopt the sediment avoidance operation mode to reduce the adverse impact of sediment on the operation of units.The special conditions during the sediment avoidance operation will also become a severe test for the safety and stability of operation,therefore,a risk analysis is carried out for the sediment avoidance operation mode of Jinping-ⅡHydropower station,and the corresponding control measures proposed at the end can effectively deal with various risks that may arise during the sediment avoidance operation.
