The purpose of this work was to design the electrical part of Nuclear power plants with VVER-440 reactors. Tasks that were solved during the design process: 1. Selection of the structural scheme of the station and the main electrical equipment. 2. Calculation of short-circuit currents at characteristic points of the circuit. 3. Selection of switching devices, current-carrying parts, current and voltage measuring transformers. 4. Development of drawings of the main circuit of the electrical connections of the station, the scheme of its own needs, the plan and section of one of the high-voltage switch gears. The first step, based on the initial data, was to select suitable generators and block step-up transformers. Then, two competitive variants of the scheme were formed. Autotransformers were selected for each circuit variant. The third stage was a technical and economic analysis of the scheme options, which showed that the most economical option was the station, in which two combined units with the VVER-440 reactor are connected to the 330 kV distribution device and one unit is connected to 110 kV. The next step was the selection of switchgear circuits of all voltages based on the voltage class, the number of connections and reliability requirements. The number of auxiliary transformers and their standby transformers was chosen: the number of auxiliaries transformer - 6, and standby auxiliaries transformer â 2. Types of TON were selected based on the known composition of their own needs mechanisms. Next, the short-circuit currents were calculated, with the help of which electrical equipment, devices and tires were selected in the future. The next stage was the selection of switching equipment-switches and disconnectors, current-carrying parts-buses and current lines, measuring current and voltage transformers. The final stage was the calculation of the system of own needs of the power plant. The choice of transformers of own needs was made, the short-circuit current was calculated, as well as the thermal pulse on the ON (own needs) sections, switching devices âswitches, current âcarrying parts-cables and buses were selected. The calculation of success self-start, as well as the start-up time of the most powerful unit, and the performance of the ON mechanisms was regulated. |
