摘要
Abstract
The reservoir storage of Dayingjiang Hydropower Station IV in Yunnan Province is small, so the sediment can not be regulated effectively. The sediment erosion resulted in serious damage to the hydraulic turbine generator in only one flood season after the operation. The design units carried out a special research and proposed to add a sediment settling treatment pool to the water power system. After the operation of the pool, the sediment amount and sediment gradation at the water intake and tail wa-ter were compared, and the sedimentation ratio, sediment grain in the pool were analyzed as well. The analysis results showed that the sedimentation of the pool was effective, which reduced the sediment passing through the turbine and mitigated the abra-sion of the turbine. No obvious abrasion was discovered during the check of the overflow parts, which have realized high effective operation of the turbine unit.关键词
