IMPACT OF VOLTAGE PHASE ANGLE CHANGES ON LOW-VOLTAGE RIDE-THROUGH PERFORMANCE OF DG-UNITS
Based on computer simulations of a simplified radial 132,66 and 22 kV system including a 5 MVA hydro power unit,it is concluded that the assessment of the units fault-ride-through (FRT) capability should be based not only on a voltage magnitude profile,but also on the change in the voltage phase angle.It is assumed that erroneous conclusions might be the result when FRT-capability studies are performed for distributed generation without taking into account the influence of the phase-angle change in this context.Further work will be conducted in order to quantify the effect of phase angle influence on the FRT capability of distributed generation units.
