description: This final qualifying work of the bachelor is devoted to the design of the electrical part of a thermal power plant operating on pulverized coal using the necessary equipment and technical and economic solutions. Tasks solved during the design: Selection of the main equipment necessary for the operation of the power plant of a given power and the main scheme of the power plant (Selection of generators, transformers and communication autotransformers). Comparison of the options for the structural schemes of the station and the choice of the most profitable scheme based on the results of the technical and economic analysis. Calculation of short-circuit currents at selected points. Selection of switching devices, live parts and measuring current and voltage transformers. Review of the composition of mechanisms and electric motors for their own needs. Assessment of the operation of the power plants own needs in emergency or repair modes, namely, verification of the success of self-start. Calculation of the start-up time of the most powerful PEN unit from the working TSN. Solving the problems of regulating the productivity of mechanisms for own needs. As a result, the main equipment and structural diagram were selected from the point of view of economic feasibility. Then the calculation of short-circuit currents was made, according to the results of which electrical devices and current-carrying parts were selected. In addition, TSN and RTSN were selected, electromechanical processes in the power supply systems for their own needs were investigated. Ultimately, the main electrical connection diagram, filling scheme, plan and section of the 330 kV outdoor switchgear are presented, as well as options for regulating the performance of some mechanisms of the power plants auxiliary needs are proposed.
