5. SIMULATION RESULTS <strong>AND</strong> CASE STUDIES Mustafa İNCİ • Single Phase Unbalance Voltage Sag • Two Phase Unbalance Voltage Sag • Three-phase balanced Voltage Sag 5.2.1.1. Case 1: Single Phase Voltage Sag The great number of faults is single-phase line to ground fault (SLGF). In this case, single phase to ground fault is analyzed. This fault occurs on Phase-C. The phase voltage decreases to 70% from its nominal value during the period of 0.3-0.4 s. In this fault, phase jump occurs between source-side and load-side voltages. Phase jump is compensated by using presag compensation method. Figure 5.5. Simulation results for Case 1 89
5. SIMULATION RESULTS <strong>AND</strong> CASE STUDIES Mustafa İNCİ Figure 5.6. DC link voltage for Case 1 DC link capacitor voltage is kept at reference value (1.7 kV) by DC-DC Converter. DC link capacitor voltage (V cap ) varies between 1.655-1.68 kV band when the voltage sag occurs as it is seen from Figure 5.6. As soon as the sag is finished, dc link voltage (V c ) returns to its steady state value. 90
