In this bachelor's work, a study was made of the 110/35 kV power supply system. Power equipment was selected, then the steady-state mode was calculated, first analytically, then using the RastrWin program, when calculating the mode in the RastrWin program, 2 cases were considered: the mode of minimum and maximum loads. Further, using the method of symmetric components, the currents were calculated single phase short circuit. Then we calculated the short-circuit currents in the EMTP program and compared the results. After all this, we proceeded to calculate the dynamic stability of the system, calculated the limiting time to turn off the short circuit to maintain the stability of our system. Further, we optimized our system by adjusting the ARV-SD coefficients, due to which we managed to reduce the time for the drop-down generator to reach the steady state. |
