Pressure-bearing type hydro-turbine generator set

Abstract

The invention provides a pressure-bearing type hydro-turbine generator set. The pressure-bearing type hydro-turbine generator set comprises a hydro-turbine, a generator and power grid co-frequency equipment, wherein the front end and the rear end of a hydro-turbine body are correspondingly provided with pressure water pipes, namely a pressure water inlet pipe and a pressure water outlet pipe correspondingly, a rotatable turbofan rotating wheel is installed in the hydro-turbine, the potential energy output end of the hydro-turbine is sequentially connected with the direct current generator, thepower grid co-frequency synchronous conversion equipment and transformer-comprising power grid connection equipment, the pressure water outlet pipe is connected with a pressure relief type hydro-turbine generator set, and the pressure relief type hydro-generator set drives the rotating wheel to generate electricity by adopting an impact or mixed flow mode. The pressure-bearing type hydro-turbinegenerator set is suitable for being additionally arranged in all high-water-head hydro-power generation stations. The pressure-bearing type hydro-turbine generator set can output electric energy as long as rotation can be achieved, and then can be connected to the grid perfectly as long as the electricity energy output can be achieved, and the pressure-bearing type hydro-turbine generator set is different from a synchronous generator which has the defects that the connection to the grid can be achieved only when the synchronous rotating speed is achieved, and when the synchronous rotating speed can't be achieved, the invalid output is caused.

Description

technical field [0001] The invention belongs to the field of hydropower equipment. It relates to a water turbine generator set, in particular to a pressure bearing type hydraulic turbine generator set. Background technique [0002] At present, my country needs energy-saving and environment-friendly generator sets to meet the people's electricity needs. The hydropower generators invented before and the wind power generators have a small power generation, and most of them are expensive, and they can't meet the electricity demand. [0003] When the existing hydropower generating units are used, it is necessary to build a dam, and the hydroelectric generator is arranged at the bottom of the dam, such as figure 1 , use the pressure water flow to generate high-speed pressure water column to push the water bucket on the runner, realize the high-speed rotation of the runner to generate potential energy and release the pressure to do work, realize the alternating current generated ...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the cost of building a dam to stop water is high, and all hydropower stations regardless of the water flow rate use this method, which is a one-time work.
