A study on continuous operation of distributed generator with DVR in case of instantaneous voltage drop

In recent years, the distributed generators have come into wide use in the small-scaled power grid, for example in the semiconductor manufacturing factory. And the customers of the generators request the machine to continue operating, during and after the instantaneous voltage sag. This paper introduces the DVR effect, operating with the distributed generators in voltage sag of the power line. The practical examination and the computer simulation was carried out in the small scaled grid.
