Abstract
An identification method of conducted electromagnetic disturbance from electrical equipment is proposed. Single supply dual power supply network is modeled by the method. The network model is nonhomogeneous differential equation of conducted electromagnetic disturbance. It is tested that the two switching power supplies of the carrier frequency are 30 and 40 kHz on power supply network. The experimental result shows that norm of nonhomogeneous term is 9.59 × 1013 and 3.03 × 1013 in the conducted electromagnetic disturbance differential equations, and the method is effective to achieve the identification of the switching power supply and independent of load fluctuations. The method has a good recognition effect and a small amount of calculation. Using the approach helps improve the flexibility and intelligence of the smart grid demand forecasting.
