Load rate is an important index to measure the safe and stable operation of the power system.In order to reduce the probability of power supply line failure,the calculation method of power supply line load rate in the power system is proposed.Digital twinning technology is used to map and process the high and low time-frequency domain of the power supply line load sig-nal,and the spectral entropy value and characteristics of the power supply line load signal are calculated by using the energy of each node of the power supply line in power system.When the power supply line is running in a normal state,the load data of the power supply line is collected to realize the load rate calculation of the power supply line.The example results show that the load rate of the power supply line can be calculated by the method in this paper,and the calculation error is controlled within 10％.
