Compressed air energy storage power station heat exchanger temperature depth coupling control method

The invention discloses a temperature deep coupling control method for a heat exchanger of a compressed air energy storage power station, and belongs to the technical field of energy storage, the method is used for controlling the water side temperature of the heat exchanger of the compressed air energy storage power station, and the method comprises a total amount control method and a partition control method, according to the partition control method, the cold water flow of each heat exchanger is controlled by controlling the opening degree of a water temperature adjusting valve at an outlet of the heat exchanger, the cold water flow of a water pump is controlled through a single-stage PID, the cold water flow of each heat exchanger is controlled through a cascade PID, and the partition control method performs own functions. The interlocking problem of the valves of the heat exchanger and the water pump is solved, the lag problem in the PID control process is solved, and the adjusting speed and the adjustin
