description: The purpose of the work: select the most technically and economically advantageous electrical component of a power plant, determine the power equipment and switchgear circuits, and check the selected equipment within the framework of a system of own needs, taking into account a given set of mechanisms of own needs. The tasks solved in this work are implemented by the calculation method: 1.The electrical part of the condensing power plant has been developed and calculated; 2.The structural scheme of the station and the main power equipment were selected: a turbo generator, a block step-up transformer, an autotransformer, transformers of own needs: working and standby; 3.The choice of the scheme of own needs is made, taking into account the working and backup power supply; 4.A choice of switchgear schemes was made taking into account the number of connections: for the 500 kV RC, a type of "double busbar system with three switches for two connections" (3/2) was selected, for the 220 kV RC 5.Short-circuit currents at 6 points of the station circuit are calculated. Based on calculations of short-circuit currents, switching devices, current-carrying parts of transformers and voltage generators were selected. 6.The calculation of electrical transients in the system of own needs is made. Based on the calculations, switching devices, working and backup transformers of their own needs were selected. 7.The possibility of self-start has been checked, as well as its time. The result of the work is a draft of the electrical part of the CPP, including an explanatory note with supporting drawings, drawings of the main circuit of the electrical connections of the station, diagrams of own needs, filling schemes of theÂ  SG-500 kV, the plan of the SG-500 kV, the section on the cell of the SG-500 kV.
