The topic of the graduate qualification work: «Selection of equipment and calculation of steady-state and transient modes of 220/110 kV power supply system».In this work a general study of 220/110 kV power supply system was carried out: such aspects as the selection of optimal equipment, calculation and testing of static and dynamic stability were considered.In the process of performing this work, the following tasks were solved:1.Selection and verification of transmission line wires and transformers suitable for a given power system;2. Calculation of the steady-state operation mode of the electric power system elements «manually» and with the help of the «RastrWin3» program on the computer;3. Determination of currents and voltages at unbalanced short-circuit «manually» and with the help of «EMTP» program on the computer;4.Analysis of dynamic stability of electric power system with the help of «Dymola» program.The result of this work is a list of equipment capable of ensuring the reliable operation of the power system, as well as measures that can be taken to increase the dynamic stability of the system. |
