The main purpose of the work: design of the electrical part and auxiliary needs of the condensation power plant 6x200 MW. Results of work: 1. Selected the main equipment and the main scheme of the power plant 2. Calculated three-phase short-circuit currents 3. Selected switching devices, measuring transformers, current conductors 4. The transformers for auxiliary needs of the first and second stage transformers were selected, the short-circuit currents in the main sections were calculated, the cables and switches were selected. 5. The calculation of the success of the self-start, the start-up time of the most powerful mechanism was made, the ways of regulating the mechanisms of auxiliary needs were selected. according to the specified conditions. The final result of the work is the design of the electrical part of the gas-and-oil condensation power plant 6 * 200 MW with drawings of the main circuit of the electrical part and the layout of electrical equipment. |
