Cooling capacity calculation method and device, computer equipment and storage medium

The invention relates to a cooling capacity calculation method. The method comprises the following steps: collecting the cooling water outlet pressure of each condenser, and respectively inputting thecooling water outlet pressure of each condenser into a hydraulic calculation model to obtain the cooling tower water feeding flow of each cooling tower; collecting atmospheric parameters, and respectively inputting the atmospheric parameters and the water flow on each cooling tower into the thermal and resistance calculation model to obtain the tower outlet water temperature and the water volumedistribution coefficient of each cooling tower; weighted averaging is conducted on the tower outlet water temperature and the water volume distribution coefficient of each cooling tower, and the towergroup tower outlet water temperature of the cooling tower group is obtained; and collecting the target tower outlet water temperature of the cooling tower group, and obtaining the cooling capacity ofthe cooling tower group acc
