Tasks that were solved during the design: 1) Selection of the main equipment and the main scheme of the power plant. 2) Feasibility study to select the most profitable structural scheme. 3) Calculation of short-circuit currents at characteristic points. 4) Selection of switching devices, live parts, busbars and measuring current and voltage transformers. 5) The choice of power plant equipment according to the composition of mechanisms and electric motors for their own needs. 6) Verification of the successful self-start of the most powerful electric motor of the station. 7) Calculation of the start time from the working TSN. 8) Selection of possible options for regulating the performance of   mechanisms for own needs. The design of the electrical part of the station has been carried out. The main electrical equipment, the most cost-effective structural diagram of the power plant, live parts, busbars were selected. Short-circuit currents are calculated. The main scheme of electrical connections has been developed, as well as a diagram of the station's own needs, filling scheme, plan and section of outdoor switching substation-330 kV are presented. |
