Abstract

The invention discloses a gas turbine and liquid compressed air energy storage coupling system and method adopting continuous detonation. The gas turbine and liquid compressed air energy storage coupling system comprises a liquid compressed air energy storage system and a gas-steam combined circulation system. Through the multi-coupling of the liquid compressed air energy storage system and the gas-steam combined circulation system, an air compressor is driven by a motor powered by a power grid, heat in the energy storage compression process is stored by a heat conduction oil heat storage tank, heat absorbed in the energy release expansion process is provided by high-temperature heat conduction oil, and released supercritical compressed air is used as fuel air of a gas turbine, dilution air and intake air of an air turbine. Air compressor and turbine decoupling is achieved, the gradient utilization degree of high-temperature exhaust heat of the gas turbine is improved, the operation efficiency of an energy storage peak regulation system is improved, and the overall peak regulation capacity of the system is increased.

Description

technical field [0001] The invention relates to the technical field of energy storage comprehensive utilization, in particular to a gas turbine and liquid compressed air energy storage coupling system and method using continuous detonation. Background technique [0002] At present, the large-scale development and utilization of renewable energy (wind energy, solar energy, water energy, ocean energy, etc.) is imperative, but renewable energy has inherent defects such as low energy density, intermittent, random, etc. Valley filling, safe and stable operation put forward higher requirements. Building large-scale energy storage devices to improve the flexibility and safety of power system operation is an effective way to solve the problem of high proportion of new energy consumption. [0003] Traditional gas turbine combustors use slow combustion to convert chemical energy into thermal energy. Slow combustion is a chemical reaction exothermic process dominated by diffusion phe...
