The topic of the graduate qualification work: «Electrical part of a dust-coal CPP with a capacity of 6*300 MW» The work carried out the design of the electrical part of the dust-coal power plant with six units of 300 MW each. During the design, the following tasks were solved: 1. Selection of basic electrical equipment. 2. Feasibility study of two structural schemes and the choice of the most profitable. 3. Calculation of short-circuit currents at characteristic points of the circuit. 4. The choice of switching devices, measuring transformers, and current-carrying parts. 5. Calculation of electromechanical processes in the auxiliary system: calculation of the success of self-start, the start-up time of the most powerful unit, the choice of a method for regulating the performance of three mechanisms of auxiliary needs according to the given conditions. The result of the work is the main circuit of electrical connections, filling scheme, plan, and section of the 500 kV switchgear. |
