The topic of the final qualifying work: "Design of the electric part of thehydroelectric power station with a capacity of 2997 MW on the Angara River.Production of operational switches".The paper considers the design of a hydroelectric power station, the prototype ofwhich was the Boguchanskaya hydroelectric power station, part of the Angarsk cascadeof the Siberian. Based on the location and specifics of this station, the main powerelectrical equipment is selected.According to the results of calculations of short-circuit currents, switchingdevices and current-carrying parts are selected. Taking into account the studiedunfavorable seismic features of the terrain, 220 kV ELK-16 and 500 kV ELK-3 CRUby ABB production were selected for high voltage, and HECSâ100 and SRNV seriesCRU by EZOIS for station-wide own needs were selected for generator voltage. Whenchoosing cables, preference is given to cables with insulation made of cross-linkedpolyethylene.The paper provides an overview of switching in a high-voltage switchgear withthe distribution of dispatching objects according to the method of control, introduction,as well as the passage of commands for the output-input of equipment, including allparticipants in the switching process. |
