SMALL TURBINE UNIT REPLACING REDUCING VALVE IN WATER SUPPLY SYSTEMS OF HYDROPOWER PLANTS

摘要

This paper is on the selection of the type of a small turbine unit, which can replace the reducer and stabilize the operation in water supply systems of hydropower plants. In high-head large-sized plants, a small turbine unit can be adopted as pressure relief installation, converting the energy of water into electric power. At the same time, a stable water pressure can be achieved for the water system at the exit. In this paper, a hydropower plant is taken as an example. This scheme is suitable for the main water supply system and its operation is simpler than the pump system. The present study is of practical value to many high-head plants.
