description: The purpose of the work was to design the electrical part of the state district power station using the experience gained over the years of the development of electric power industry, modern technical solutions and relevant equipment. Tasks that were solved during the design: 1. Selection of basic electrical equipment and determination of the structural scheme of power plant. 2. Calculation of symmetrical short circuit currents at characteristic points of the circuit. 3. Selection of switching devices, conductors, measuring current and voltage transformers. 4. Calculation of asymmetric short circuit currents at selected points of the circuit. 5. Consideration of the protection of the generator-transformer block. 6. Development of drawings of the main circuit scheme of the electrical connections of the power plant and switchgear design. For the selected optimal structural scheme, a feasibility was carried out, turbogenerators, power transformers, auxiliary transformers, autotransformers and switchgear were selected. Circuit breakers, disconnectors, busbars, cables, measuring currents and voltage transformers were selected based on the calculation of three-phase short circuit currents. The equipment was tested under conditions of continuous operation in normal mode, for thermal and electrodynamic resistance during short circuits, for switching ability. The protection of the generator-transformer block was considered in accordance with the PUE. The result of the work is the design of the electrical part of the state district power station, including an explanatory note with substantiating calculations, drawing of the main circuit scheme of the GRES (SDPP) and the design of the 110 kV switchgear.
