description: Subject matter of graduate qualification work: "Transient processes analysis in the networks of generator voltage 20 kV power unit 300 MW". This work is devoted to the analysis of transients that may occur in networks of generator voltage 20 kV, as well as consideration of their impact on the modes of operation of voltage transformers, taking into account their magnetization characteristics. The research set the following goals: 1. Calculation of parameters of a substitution scheme of a generator power unit of an electrical plant. 2. Construction of characteristics of magnetization curves of voltage transformers. 3. Building a mathematical model of the power unit using the simulation environment "MATLAB/Simulink". 4. Analysis of transients in the power unit, their impact on the operating parameters of voltage transformers. The work was performed on the data obtained in the course of the accident by the recorder of emergency events, installed at one of the power units of the power plant. The substitution diagrams for the equipment included in the power unit was calculated. Based on the measured and calculated data, the magnetization characteristics of voltage transformers were constructed, which were subsequently corrected so that the model would reliably reflect the emergency processes that had occurred. Possible technical measures to reduce the chances of occurrence of ferroresonance processes are considered.
