The aim of the work was to design the electrical part of the state district power station using modern equipment and technical solutions. Tasks that were solved during the design: 1) selection of the block diagram of the station, the main electrical equipment, switchgear diagrams; 2) calculation of currents of symmetric and asymmetric short circuits at characteristic points of the circuit; 3) selection of electrical apparatus, conductors, measuring current and voltage transformers; 4) selection of equipment and technical solution for the software and hardware complex of the system for measuring, accounting and controlling the quality of electric energy. Calculations substantiating the decisions made were carried out using the software "Mathcad 15", "Excel", "RastrWin3", vector diagrams of currents and voltages during short circuits were built using "Excel". The graphic part of the work was done in the AutoCad 2019 program. The result of the work is a project of the electrical part of the GRES, including an explanatory note with explanatory calculations, drawings of the main electrical connection diagram of the GRES, the design of the 110 kV switchgear, and the block diagram of the software and hardware complex of the automated system. |
