Abstract

The integration of distributed generation transforms current distribution networks from vertically operated to horizontally operated. This transition leads to problems related to protection coordination. In the future, new protection philosophies should be applied which guarantee the increase of the during-fault distributed generation availability. The paper presents a protection scheme based on fault transient analysis. It also explicitly describes the concept of integrated protection unit and the IEC61850-9-2 process bus concept. The effectiveness of the protection principle is tested for a converter based doubly fed induction generator wind turbine. Simulation results reveal proper operation of the protection scheme in the case of not sustained fault current contribution.
