The theme of the final qualification work: "The electrical part of thepulverized coal-fired power plant with a capacity of 5x320 MW."This work consists in designing the electrical part of a power plant operating onpulverized coal fuel.Tasks to be solved during the design:1. Selection of the optimal structural diagram of the power plant based on theresults of the calculation of power flows.2. Selection of the main electrical equipment of the power plant based on theconditions of the task and the selected block diagram.3. Calculation of short circuit currents at the main points.4. Selection of switching equipment and equipment of current-carrying parts ofthe power plant.5. Review of the composition and evaluation of the operation of the mechanismsof their own needs under the conditions of self-start.6. Calculation of the start time from the working TSN.Based on the results of the work, a block diagram and the main equipment of thepower plant were selected. The calculation of short-circuit currents was made, thanksto which the choice of switching equipment was made. An analysis of the operation ofthe mechanisms of their own needs was made. |
