Title:
SINGLE-TUNNEL MULTI-LEVEL HYDROELECTRIC POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/188119
Kind Code:
A3
Abstract:
A single-tunnel multi-level hydroelectric power generation device. Two or more hydro turbines (2) are installed in a single diversion tunnel (1). The sum of the cross-sectional areas of the diversion tunnel (1) sections corresponding to the downstream hydro turbines is the formula (I) multiplied by the sum of the cross-sectional areas of the diversion tunnel (1) sections corresponding to the upstream hydro turbines. The downstream hydro turbines are mounted at the frontmost position of the corresponding diversion tunnel (1). The transition section from the diversion tunnel (1) corresponding to an upstream hydro turbine to the diversion tunnel (1) corresponding to a downstream hydro turbine is a divergent section (3), the cross-sectional area whereof increases gradually. The device can improve the generating efficiency and generating capacity by 80-99%. The hydroelectric power cost is reduced and the effect of the noise on the surroundings is reduced during the hydroelectric power generation process.
