All the voltage and current measurements for the converter in Figure 1 are processed using the following Clarke and Park transformation formulae: Clarke transform: (a) = ( Park transform: upcoswt -sin wtfal fallsin wt coswt fpl where wt is equal to the phase angle of grid phase voltage. Their fa and fo components for the measured three phase currents flowing into the grid are- (10 XF) and (22.5 XF) A respectively where P=0.42. The RMS phase voltage for the grid is 230 V and it is based on 50 Hz. Assume the effect of current harmonics can be ignored. a) Determine if Ig is leading or lagging the phase A grid voltage and by how much? b) Determine the three phase active power delivered to the grid and the power factor measured at the grid. c) Determine the values of Land R if the fa and fd components for the converter output voltage are 8 and (330 + 10 x F) V respectively where Fhas the value given above.
