Power generation system with coal-fired Brayton cycle power generation as base load integrated wind power generation

Abstract

The invention discloses a power generation system for integrated wind power generation by taking coal Brayton cycle power generation as a base load. The power generation system comprises a wind power generator set, an electric heater, an energy storage compressor, a low-pressure CO2 storage tank, a main compressor, a high-pressure CO2 storage tank, a low-temperature heat regenerator, a high-temperature heat regenerator, a coal boiler and a turbine. The system can realize coupling of coal Brayton cycle power generation and wind power generation.

Description

technical field [0001] The invention relates to a power generation system, in particular to a power generation system which uses coal-fired Brayton cycle power generation as the base load and integrates wind power generation. Background technique [0002] my country's electricity is dominated by coal power, and the economic take-off since the reform and opening up has promoted the rapid increase in the capacity of coal-fired units. During the combustion process of pulverized coal, a large amount of dust, nitrogen oxides, sulfur oxides, heavy metals and other pollutants will be emitted, as well as a large amount of greenhouse gases, which has caused great adverse effects on the ecological environment. In addition, coal is a non-renewable energy, which will eventually be exhausted one day. Therefore, energy conservation and emission reduction is the direction that coal-fired power plants must persist in their life cycle. [0003] Due to the excellent physical and thermal pro...

Problems solved by technology

[0004] Wind energy is a clean and renewable energy that is relatively easy to use. The vigorous development of wind power generation can alleviate the problem of environmental pollution in my country. However, due to the randomness and volatility of wind energy, it is difficult for the grid to accommodate large-scale wind power. The phenomenon of wind is becoming more and more prominent

[0005] If the coal-fired Brayton cycle can be coupled with wind power generation, on the one hand, the clean energy of wind energy can be used to further reduce the coal consumption per unit output of the power plant; The power generation of the power plant remains stable, avoiding the phenomenon of wind curtailment due to the inability of the grid to absorb it, but there is no technology that couples coal-fired Brayton rings with wind power generation in the existing public information
