Water-cooling power supply control method and system based on power factor correction

The invention discloses a water-cooling power supply control method and system based on power factor correction, and the method comprises the steps: obtaining power supply operation monitoring information, carrying out the power factor calculation according to the power supply operation monitoring information, and carrying out the power factor change analysis; setting performance evaluation indexes, allocating subjective weights and objective weights to the evaluation indexes, performing weight combination to obtain a final evaluation weight, and performing performance evaluation on the target power supply; whether power factor correction needs to be carried out is judged according to a performance evaluation result, a voltage prediction model is constructed, voltage change is predicted, and a compensation coefficient is calculated for control; obtaining power supply temperature monitoring information, analyzing the influence of the power supply temperature on the power supply performance according to the pow
