description: The purpose of the final qualification work is to develop an electrical power supply system for the repair and mechanical workshop of an industrial enterprise. During the development of the power supply of the repair and mechanical shop, electrical loads were calculated, an optimal power supply scheme was drawn up, a subgroup breakdown of consumers was performed taking into account the requirements of reliability of power supply, the required transformer power and the power of compensating devices were calculated, 0.4 kV cable lines were designed, followed by checking them for overload, voltage loss and thermal resistance to short-circuit currents, three-phase short-circuit currents are calculated. On the tires of the electric receivers, the recharge from the electric motors of power machines is taken into account. The calculation of short-circuit currents is carried out in order to ensure the selection and verification of equipment and protection devices (automatic machines). During the development of the WRC, the entire written and calculated part was developed based on the current versions of regulatory and technical documentation and on the relevant requirements for technical and economic indicators. Special attention is paid to the regulatory and technical documentation and the norms of technical and economic indicators in order to ensure the maximum capacity of the projected power grids and ensure the proper quality of the supplied electric energy to the consumer.
