description: The theme of final qualification work: Â«Influence of motors load on the checking conditions to heating cables up to 1000 VÂ». The goal of this work was the considering the issue of the relevance of accounting for make-up from motors in 0.4 kV networks during a short-circuit in various cases. Tasks which were solved during educational designing: 1. The selection of the main power electrical equipment and the choice of the structural circuit of the power plant, including the choice of the structural circuit of own needs 0.4 kV. 2. Calculation of currents of a three-phase symmetric short-circuit at characteristic points of a power plant with voltages above 1000 V. 3. Designing figures of the main electrical circuit of the power plant and circuit of own needs 0.4 kV. 4. Calculation of short-circuit currents of various types in networks with voltages below 1000 V by iterative method using specialized software. 5. Improvement of the software-computing module for calculating the heating cable lines in networks above 1000 V based on Microsoft Access. 6. Analysis of the influence of the motors load on the checking conditions to heating cables up to 1000 V. The result of the work is a finished project of CPP which includes an explanatory note with the necessary calculations, figures of the main electrical circuit of the CPP and the circuit own needs 0.4 kV, a Microsoft Access-based program for calculating short-circuit currents and heating cable lines in networks below 1000 V, and also the calculations that were performed in this software and the conclusions on them.
