Water Turbine Technical Improvement for Golovnaya Hydro Power Station in Tajikistan |
| |
| Abstract: | In order to solve the problem of the vibration and insufficient output of water turbine in Tajik Golovnaya station, this paper proposes the turbine reconstruction scheme of reducing the runner diameter considering insufficient depth of the draft tube. And then the simulation calculation is implemented on the whole flow passage of water turbine with CFD analysis method. The results show that the hydraulic performances of water turbine including energy index, hydraulic stability and cavitation performance meet the requirements of power plant. |
