The subject of the work is the electrical part of the GRES with a capacity of 3x800 + 3x300 MW. on the example of the Perm GRES. The purpose of the work is to design the electrical circuit of the GRES corresponding to modern design requirements. The following tasks are solved in the work: 1) investigation of the properties of PGU-800 and PTU-800, feasibility study by the method of the reduced costs of the layout of the RC and the development of the main circuit of the electrical connections of the PS; 2) calculation of three-phase short-circuit currents, selection of switching devices and current-carrying parts; 3) development of an automated information and measurement system for electricity metering. Research was held by methods of analyzing literature and regulatory and technical documents, studying and summarizing information on the production and transmission of electric energy. The study resulted into the electrical part of the was developed, a circuit with two bus systems and three switches for two circuits. The advantage of this scheme is that during the revision of any switch, all connections remain in operation. Another advantage of this scheme is its high reliability. The results of the work can be applied to the construction of electrical parts of power plants. |
