description: Subject of research: the electrical part of a pulverized coal condensing power plant.Topic of work: The electrical part of a pulverized coal powerplant with a capacity of 4Ã500 MW.The purpose of the work: to select the most technically and economically advantageous electrical part of the power plant, to make a choice of power equipment, switchgear circuits, as well as to check the selected equipment in the system of own needs, according to the specified composition of the mechanisms of own needs.The tasks solved in this work are implemented by the calculation method:1. The electrical part of the condensing power plant has been developed and calculated;2. The structural scheme of the station and the main power equipment were selected: a turbo generator, a block step-up transformer, an autotransformer, transformers of own needs: working and standby;3. The choice of the scheme of own needs is made, taking into account the working and backup power supply;4. A choice of switchgear schemes was made taking into account the number of connections: for the 500 kV RC, a type of "double busbar system with three switches for two connections" (3/2) was selected, for the 200 kV RC, a type of "Double unsectioned busbar system with a bypass busbar system with one switch per connection" was selected.";5. Short-circuit currents at 6 points of the station circuit are calculated. Based on calculations of short-circuit currents, switching devices, current-carrying parts of transformers and voltage generators were selected.6. The calculation of electrical transients in the system of own needs is made. Based on the calculations, switching devices, working and backup transformers of their own needs were selected.7. The possibility of self-start has been checked, as well as its time.The result of the work is a draft of the electrical part of the CPP, including an explanatory note with supporting drawings, drawings of the main circuit of the electrical connections of the station, diagrams of own needs, filling schemes of the SS-500 kV, the plan of the SS-500 kV, the section on the cell of the SS-500 kV.
