description: Topic of the final qualification work :" selection of equipment and calculation of electric modes of the 500/220 kV electric power systemÂ»
This work is devoted to the study of operating modes of the electric power system of voltage classes 500/220 kV. During the work was checked and selected cross-sections of the wires overhead lines and transformers parameters calculated by the steady operation of elements of power system manually and with the help of iterative calculations using the software were found currents and voltages when unbalanced single-phase short circuit was the calculation of dynamic stability in tremosine equivalent circuit of single-phase and three-phase short circuit. Determination of the limiting angle and turn-off time.
As a result of the calculation, it was shown that the electric power system is resistant to a standard disturbance such as a single-phase short circuit with a standard duration of 0.16 s and the action of 0.3 s URS. Measures have been proposed to improve dynamic stability in three-phase short circuits, such as setting up an automatic excitation regulator and automatically re-enabling the line. Which generally increased the limit angle and short-circuit cut-off time.
