description: Purpose of work: designing the electrical part of IES using modern equipment and technical solutions. Tasks that were solved during the design: 1. The choice of basic electrical equipment and structural diagram of the station. 2. Calculation of short circuit currents at characteristic points of the circuit. 3. The choice of electrical apparatus, conductors, measuring transformers of current and voltage. 4. Development of drawings of the main circuit of the electrical connections of the station and the design of the switchgear. 5. A review of the composition of mechanisms and electric motors of their own needs. 6. The calculation of the success of self-launch. 7. Calculation of the start-up time from the working transformer of auxiliary needs. 8. The choice of regulating the performance of mechanisms. When carrying out the work, the optimal structural scheme of the IES and the main equipment (generators, block transformers, communication autotransformer) were selected for economic feasibility. After that, the calculation of short-circuit currents at different voltages was carried out for the further selection of current-carrying p arts and electrical apparatus of the station (switches, disconnectors, buses, current leads, measuring transformers of current and voltage, cable lines). Electromechanical processes in auxiliary power supply systems are investigated. You have chosen working and backup transformers. The conditions for successful self-start of TSN and RTSN are calculated. The regulation of the productivity of mechanisms is determined. The result of the work is the design of the electric part of the IES, including an explanatory note with the rationale for the calculations, drawings of the main electrical connections of the power plant and the design of the 220 kV switchgear.
