description: The subject of the graduate qualification work is Â« Selection of equipment and calculation of steady-state and transient power systems 330\110 kV Â». The research set the following goals:
1. Selection of appropriate equipment (power transformers, autotransformers, overhead lines, etc.) with verification according to permissible standards.
2. Calculation of the steady state of the electric power system manually and using the RastrWIN3 software.
3. Calculation of currents of an asymmetric short circuit at the point indicated by the teacher.
4. Ð¡alculation of the dynamic stability of the system, as well as increasing in dynamic stability.
At the beginning of the work, equipment was selected and checked according to acceptable standards. Further, with calculating of steady state, measures were taken to install reactive power compensation devices and regulate on-load tap-changers of transformers and autotransformers. Subsequently, asymmetric short-circuit currents (single-phase) at the end of the second overhead line were calculated. To sum up, the dynamic stability of the system was calculated, and measures were taken to increase it.
