Firstly, capacitive compensation is set on the transformer side of the distribution room to reduce the electricity cost by improving the power factor, avoiding reactive power penalty and obtaining reactive power reward. Second, the inductive load of the motor is set up on the local side capacitance compensation, which reduces the electricity cost by reducing the starting and running current. Third, capacitive filter device is set to remove harmonics of the system, which reduces harmonic energy consumption and reduces electricity costs. In addition, the above three measures also reduce equipment investment by improving efficiency, while reducing carbon dioxide emissions.
