【Abstract】 A novel method to detect real-time reactive power was presented based on wavelet transform. The method could simply detect power-factor of power system by discrete collected date of power system voltage and current. By calculating the fundamental component of power system voltage and current, the real-time data could be obtained. Numerical simulation was given to demonstrate the effectiveness of the proposed method.更多还原
