Abstract: The cable recovery operation will cause the cable structural deformation. Due to different recovery methods, there are different deformation states such as coil, reel and bending. Theses states cause differences in cable distribution parameters, which have influences on the main line voltage loss in long-distance power supply. The problems of existing analytical calculation of cable distribution parameters are complicated implementation process, limited extraction accuracy of distribution parameters and not being applicable to large deformation in the cable recovery process. In order to solve the above problems, this paper proposes a method to analyze the changes of cable distribution parameters in the process of cable recovery by using ANSYS and the working principle of monorail crane and cable car. The influence of cable car recovery method and monorail crane recovery method on cable distribution parameters and heat dissipation is analyzed. The influence of the cable recovery method on the long-distance power supply of the fully mechanized working face is analyzed by using ETAP. The analysis results show that the coil, reel, and bending deformation of the cable caused by the recovery operation will cause small changes in the capacitance value, the conductance value and the resistance value, and cause significant reduction of the inductance value. When the monorail recovery method is adopted, the cable deformation is greater and the inductance value per unit length is smaller with a drop of up to 29%. Compared with the cable car recovery method, the monorail crane recovery method has more advantages in terms of automation, cable heat dissipation and main line voltage loss. The changes in cable distribution parameters lead to changes in main line voltage loss. With the increase in cable recovery distance, the total voltage loss of each main line of the long-distance power supply system shows a decreasing trend as a whole. There is an increase in some parts of the main line, which influences the longest power supply distance and equipment carrying capacity.
