南告水电厂水轮机转轮更换改造实践

Replacement and remodification of hydraulic turbine runners in Nangao Hydropower Plant

南告水电厂在进行了充分的可行性研究的基础上， 以不改动原有水轮机各种结构和尺寸为条件， 利用科技进步成果， 对水轮机转轮进行了更换改造， 不仅提高了水轮机的效率， 也为今后机组增容打下了良好的基础。

Based on full feasibility study and without changing the original structure and dimensions of the water turbines,the turbine runners in Nangao Hydropower Plant were changed and remodeled with advanced sci tech achievements.The efficiency of the turbines was thereby improved and a good foundation was laid for future capacity expansion of units.
