Embodiment Construction
[0017] The invention has been described herein in terms of specific exemplary embodiments. Appropriate substitutions or modifications will be apparent to those skilled in the art without departing from the scope of the present invention. The exemplary embodiments are illustrative only, and not limiting of the scope of the invention, which is defined by the appended claims.
[0018] The compressed air energy storage power generation system of the embodiment of the present invention, see figure 1 , including compressor 1, cooler 2, first storage tank 3, hydraulic pump / engine unit 4, second storage tank 5, dehumidifier 6, heat exchanger 7, combustor 8, gas turbine 9, generator 10 and seal Liquid storage tank 11.
[0019] The compressor 1 compresses the external air to store electricity, and when the electricity load is low, the motor uses the low electricity to drive the compressor 1 to operate, thereby storing energy in the compressed air. The compressor 1 can be a single com...

The invention discloses a compressed air energy-storing and peak-shaving power generation system which comprises a compressed air storing tank used for storing trough electric power, and a sealed liquid storing tank. The compressed air storing tank stores energy in an electric power trough and releases energy to generate power through a gas turbine in an electric power crest. Sealed liquid located in the sealed liquid storing tank is input into the compressed air storing tank through the sealed liquid storing tank, and therefore a liquid sealing layer between a sealed air interface and a stored water interface in the compressed air storing tank is formed. The amount of volatizing stored water entering compressed air is reduced, and corrosion and damage to subsequent parts are avoided.
Description
technical field [0001] The invention relates to an energy storage power generation device, in particular to a gas turbine energy storage power generation system used to meet peak load regulation. Background technique [0002] As a basic social industry, the electric power industry is one of the lifeline industries for national development. With the rapid development of China's economy and society, the demand for electricity is increasing day by day, and the construction of China's electric power industry has entered a period of rapid development. With the advancement of science and technology and the promotion of social needs, the power grid is evolving from traditional transmission, transformation, and distribution to an energy carrying and energy game platform whose main function is to meet the optimal allocation of social resources. Under the background of energy structure adjustment, as the power system has higher and higher requirements for safe, efficient, and stable ...
