Study on Optimization Plan of Water Diversion System with High-head and Small Flow Hydropower Station

The water diversion system is an important part of the hydropower station with high-head,small flow and long water diversion line.The Reliability of water diversion system should be taken more attention to in designing.Through the comparation of three plans,the plan of whole tunnel drawing is adopted.This plan can not only make sure the engineering safely operation,but also be valuabe to the environment and water protect.
