description: This work is devoted to the design of the electrical part of a small HPP with the development of an algorithm that allows the power supply of the station's own needs from a backup source. Tasks that were solved in the course of the work: 1) overview of opportunity and legal regulation on the use of electricity from renewable sources in Russia and abroad; 2) design of the electrical part of the station, including the selection of switching devices and the development of the main circuit of electrical connections; 3) development of an algorithm for the introduction of a diesel generator for power supply auxiliary mechanisms. During the design process, a preliminary selection of power equipment and current-carrying parts was made for calculating the three-phase short-circuit current at characteristic points on the switchgear busbars. The choice of switching devices for each switchgear is justified, as well as plans for the placement of equipment for 10 kV and 0.4 kV switchgear are given. In the LOGO!Soft has developed an algorithm for introducing a backup power source for the station's auxiliary mechanisms in the event of a power loss from the main power source of the 10 kV switchgear.
