[0004] In 2010, the article "Improving the Response Speed of Rotating Generators by Increasing the Speed and Magnetic Flux" published in the journal [Mechanical Science and Technology] analyzed and concluded that the effect of increasing the response speed of the generator by reducing the starting wind speed of the generator is limited. When the load of the generator is heavy or the output voltage is high, the response speed of the generator cannot be improved
[0005] Typical physical energy storage technology Flywheel energy storage. During energy storage, the motor drives the flywheel to rotate at a high speed. The flywheel stores electrical energy in the form of kinetic energy. When the energy needs to be released, the high-speed rotating flywheel drives the motor to generate electricity to complete the energy conversion from kinetic energy to electrical energy. process, the flywheel energy storage power generation technology responds quickly, but its loss is relatively large

The invention relates to an impulse turbine energy storage quick-response power generation system and method, and belongs to the technical field of energy storage power generation. According to the method, mechanical kinetic energy is stored by driving a turbine to rotate at a high speed, a generator is driven to generate power by utilizing the mechanical kinetic energy generated by turbine speedreduction during energy release, and power is supplied to a load through power conversion. The invention provides the novel energy storage power generation method. Rapid power supply to the instantaneous pulse load can be realized. The control of the turbine and power generation is decoupled. When the turbine rotates, the loss is small, and the energy storage efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of energy storage power generation systems, and in particular relates to a shock turbine energy storage quick response power generation system. Background technique [0002] Turbine power generation technology driven by steam turbine or gas turbine has the advantages of continuous high power output and reliable operation. It is widely used in power stations, ships, aircraft and other occasions. It is an important means of power generation in the world at present. In turbine power generation technology, the turbine converts thermal energy and pressure potential energy into kinetic energy, and then the generator converts kinetic energy into electrical energy. Among them, the steam turbine uses the superheated steam generated by the boiler to drive the turbine to expand and do work, and the gas turbine uses the air to pass through the compressor and the combustion chamber to obtain high-temperature and high-pre...
