AI Technical Summary
In existing compressed air energy storage systems, the compressor has a long start-up time, making surge problems difficult to avoid. Furthermore, the release of high-pressure gas after the filling process results in low efficiency and fails to meet the response speed requirements of the power grid for peak shaving.
It adopts a multi-stage compressor system, equipped with a pressure sensor, anti-surge valve, check valve and controller. The controller adjusts the opening of the gas supply valve to quickly raise the compressor inlet gas pressure to the preset value. The multi-stage compressor starts synchronously, and high-pressure gas is retained through the check valve and outlet regulating valve to reduce losses.
It shortens the compressor start-up time, improves system response speed and stability, reduces high-pressure gas loss, and enhances system efficiency and lifespan.
