description: The theme of the qualification work is âThe calculation of steady and transient modes in the 220/110 kV power supply systemâ. The object of a study is a two-machine power supply system, which consists of a power system, an electric station and 4 loads.
In the course of this work, the choice of equipment for the electric power system was made. Then the steady state mode was calculated both manually and using the RastrWin program, as a result of which the voltages in all nodes, the power flow distribution in the network, and the power loss in all branches were obtained. The next step was the calculation of currents and voltages of an asymmetric (single-phase) short circuit at the beginning of first power line, voltage of which is 220 kV, and also vector diagrams were built. This calculation was performed by the method of symmetrical components. The final part of the work consisted of the calculation of dynamic stability in the Dymola software, in addition, measures to increase dynamic stability were applied.
The result of the thesis was a designed system that satisfies the requirements of dynamic stability and is able to provide consumers with electricity of the required quality.
