13.1 Introduction
Among many types of disturbances that can appear in power system, voltage sags can lead to the highest level of undesirable impact on sensitive loads. Short circuit faults, starting up of large loads such as induction motors are the major causes of this voltage sag. For the compensation of the amount of voltage sag, dynamic voltage restorer (DVR) is designed. It is also proposed ...
