Abstract

The invention discloses a single-channel multi-level hydraulic power generation technology. A single headrace channel (1) is provided with two or more water turbines (2). The cross section area, corresponding to the headrace channel, of the downstream water turbines is n times of the cross section area, corresponding to the headrace channel, of the previous-level water turbines, wherein n is shown in the specification. The downstream water turbines are installed at the position corresponding to the foremost end of the headrace channel. A transition section between the part, corresponding to the headrace channel, of the previous-level water turbines and the part, corresponding to the headrace channel, of the downstream water turbines is a gradual expansion section (3) with the cross section area gradually increased. According to the implementation expectation of the technology, the hydraulic power generation efficiency can be improved by 90%-99%, the hydraulic power generation cost is reduced by 50%-60%, the proportion of hydraulic power generation in an energy structure is changed, and an outstanding function is achieved.

Description

[0001] Technical field [0002] The invention belongs to the technology of hydropower generation, and relates to a method of sequentially installing two or more water turbines in a single water diversion channel along the flow direction of the water head. Connected, multi-stage hydroelectric generating units are expected to improve the utilization of water energy. Background technique [0003] At present, a water turbine is installed in a single diversion channel of existing hydroelectric power generation, and the water turbine is connected with the generator set through a rotating shaft, (the branch canal can be treated as a single canal), that is, the single-canal primary hydropower generation. In the process of hydropower generation, due to the water level difference, the potential energy, potential energy and kinetic energy of the head of the diversion channel drive the turbine to rotate, and the water energy E 水 (The energy before flowing into the turbine) is converted i...
