description: The topic of the final qualification work: "Selection of equipment and calculation of electrical modes of the 330/220 kV electric power system".
This work is devoted to the selection of equipment, calculation of the steady state and transient processes in the electric power system, as well as the analysis of its dynamic stability.
Tasks that were solved in the course of this work:
1. Preliminary selection and verification of power line sections and transformer parameters.
2. Calculation of the steady state mode of the EPS analytically and using the RASTR software package.
3. Determination of currents and voltages at an asymmetric short circuit (transient process).
4. Calculation of dynamic stability in this EES and application of measures to improve it using the Dymola software package.
As a result, we have selected and tested (based on reliability considerations) elements of the network. Calculated steady-state operation mode of the power plant, to achieve which various means were applied (voltage regulation under load, voltage regulation on the generator, compensating devices). The short-circuit mode is calculated using a special method of symmetrical components, which greatly simplifies this calculation. The dynamic stability of the resulting circuit is analyzed and measures to increase it are shown (the method of parallel electric braking was used). As a result, our system and the measures applied in it will allow us to reliably supply the consumer with electricity and maintain stability in the event of disturbances, which will ensure uninterrupted supply.
