description: The subject of the graduate qualification work is Â«Design of the electric part of the coalfired condensation power plant with a capacity of 5*300 MWÂ». This work is devoted to the design of a condensation power plant with a capacity of 5*300 MW. The research set the following goals: 1. The choice of the structural electrical circuit and basic power equipment. 2. The calculation of the short-circuit currents. 3. The choice of switching and measuring equipment, as well as conductors. 4. Consideration of the power plant's own needs system. 5. The study of electromechanical processes, including self-start, start-up, as well as regulation of the performance of auxiliary mechanisms. 6. Design the main electrical circuit of the power plant indicating its own needs, the filling scheme, plan and section of the switchgear According to the initial data, generators, step-up transformers, as well as autotransformers were selected. Different variants of the structural electrical circuits based on the number of units of the power plant were considered, and depending on the results of the technical and economical analysis the final version of the electrical circuit was selected, according to which the main electrical circuit was designed. Furthermore, the short-circuit currents were calculated, the values of which were subsequently used to select the necessary electrical equipment (devices and conductors). We also consider the stationâs system of own needs, for which equipment was also selected, which was later reflected on the main circuit. In addition, the calculations of the self-start and start-up time of the most powerful unit were done. Using selected mechanisms as an example, various ways of regulating productivity were considered and the most suitable ones were chosen.
