Аналіз режимів трансформаторів і синхронних генераторів

Abstract

In master's work the analysis of work of possible operational and emergency modes of power transformers: idle and short circuit, normal operation mode, considered issues of reloading capacity and parallel work of transformers and their economic modes of work. The main modes of synchronous generators operation are considered, calculations of the coefficients of the static stability of the hydrogenerator, calculations of the transition process during the switching off of the power line, as well as calculations on the influence of the voltage Uk of the transformer on the currents of the breach occurring in the electrical network have been made. The issues of ensuring the safety of personnel at the installation of power transformers are considered. The calculation of the optimal mode of operation of two transformer substations based on the minimum of losses of active power is given.
