Let the average active power of the equipment to be compensated be \(P_{\text{av}}\), the power factor before compensation be \(\cos\phi_1\), and the power factor after compensation be \(\cos\phi_2\). Then the reactive power compensation capacity is:\(Q = P_{\text{av}}(\tan\phi_1 - \tan\phi_2) = P_{\text{av}}\left( \sqrt{\frac{1}{\cos^2\phi_1} - 1} - \sqrt{\frac{1}{\cos^2\phi_2} - 1} \right)\)Q: Reactive power compensation capacity (kvar);\(P_{\text{av}}\): Average active power of the motor to be compensated (kW);\(\tan\phi_1\): Tangent value of the power factor angle before improvement;\(\tan\phi_2\): Tangent value of the power factor angle after improvement;\(\cos\phi_1\): Power factor before improvement;\(\cos\phi_2\): Power factor after improvement.
