5. SIMULATION RESULTS <strong>AND</strong> CASE STUDIES Mustafa İNCİ Figure 5.15. DC link voltage for Case 4 DC link capacitor voltage is kept at reference value (1.7 kV) by DC-DC Converter. DC link capacitor voltage (V cap ) varies between 1.66-1.683 kV band when the voltage sag occurs as it is seen from Figure 5.15. As soon as the sag is finished, dc link voltage (V c ) returns to its steady state value. RMS characteristics of Phase A, Phase B and Phase C voltages are seen in Figure 5.16 when single phase voltage sag occurs on Phase C. 99
5. SIMULATION RESULTS <strong>AND</strong> CASE STUDIES Mustafa İNCİ Figure 5.16. RMS characterisics for Case 4 5.2.2.2. Case 5: Two Phase Voltage Sag A and B phase source voltage decreases to 70% from its nominal value during the period of 0.3-0.4 s. In A and B phases, phase jump occurs between source-side and load-side voltages. DVR operation for double line to ground fault is seen in Figure 5.17. It shows the simulation results of source-side, injected and loadside voltages under double-phase to ground fault. The load voltage is maintained at the desired 1 p.u. as shown in Figure 5.17. 100
