- Abstract
In the light of the study of the influence of electromagnetic looped networks on the reliability of power supply is studied, and the calculation method for overload rate of in - lines connected to the Infinite systems and tie - lines between substations is studied in this paper. According to the connection between two or more 220 kV substations, the model of the overload probability model of the in - lines and the tie - lines is analyzed. According to the uncertainty of load variation, the correlation analysis between the load rate and the overload rate of the electromagnetic looped networks is carried out under a certain load level. The reliability calculation method of overload rate of the in - lines and tie - lines in electromagnetic looped networks between substations is presented. In this paper, an electromagnetic loop network between two 220 kV substations in a large power grid is taken as a study example. The calculation and analysis of the overload probability of the in - lines and the tie - lines under various operating modes are carried out. The influence of operation of electromagnetic loop networks on power supply reliability is revealed.
