description: Six units of 200 MW each are to be installed at the plant. In the domestic power systems, the share of condensing power plants is about half of the generated energy. The capacity of generators installed at CES is steadily increasing. Power units of 500, 800 and 1000 MW have been put into operation. The installed capacity of modern CHPPs reaches several million kilowatts. The buses of such power plants link several power plants and transfer power from one part of the power system to another. All this leads to the fact that large CHPPs play a very important role in the power system. CHPPs have a number of peculiarities: - it is built near a fuel deposit; - feeds most of the power into the system at elevated voltages; - operates on free schedule of power generation; - low maneuverability; - has a low efficiency, about 30-40%. Communication with the power system is carried out by overhead lines of two voltage classes: 220 kV and 500 kV. The explanatory note contains: - selection of generators, step-up transformers, coupling autotransformers, operating and standby auxiliary transformers; and also, transmission lines. - Calculation of short-circuit currents on the 220 kV and 500 kV switchgear busbars, on generator outputs, and auxiliary busbars; - choice of switching devices, busducts, current carrying parts. The drawings present: - structural diagram of power plants; - Power plant schematic diagram of electrical connections; - Layout of equipment on the territory of the power plant; - Substitution diagram and its transformation to calculate short-circuit currents.
