Topic of the final qualifying work: "Electrical part of a gas turbine thermal power plant with power units with a capacity of 4x160, 100 and 300 MW".The work is devoted to the development of a project for the electrical part of a thermal power plant with power units with a capacity of 4x160, 100 and 300 MW using modern equipment and technical solutions, as well as methods for diagnosing cable lines.Tasks that were solved during the design:1) selection of the main electrical connection diagram of the TPP;2) calculation of short circuit currents;3) selection of switching devices and current-carrying parts;4) analysis of diagnostic methods for cable lines.In the course of designing, the choice of the main power equipment of the thermal power plant was made, a feasibility study was made for the choice of 110 and 220 kV outdoor switchgear circuits, three-phase short-circuit currents were calculated, according to which a further selection of electrical devices and conductors for 220, 110 and 10 kV switchgear was made.The paper also considers the experience of using cables with oil-impregnated insulation and XLPE insulation, as well as the experience of their diagnostics, methods for detecting damage and repairing.The result of the work is a project for the electrical part of a thermal power plant with power units of 4x160, 100 and 300 MW, containing an explanatory note with calculations, the main electrical connection diagram of the thermal power plant, as well as materials on diagnostic methods for cable lines. |
