Commonly, Distance protection function and its settings are designed for grids largely dominated by synchronous generators. Nevertheless, today’s renewable generator farms such as; photovoltaic systems, Type 3 and Type 4 wind turbines are interconnected to the grid through partial or full-scale power electronic (PE) voltage source converters (VSC). They have the capability of fast switching in order to control their output power if necessary during an event. The control strategy and the electric circuit are substantially important in the short-circuit current characteristic in PE-based generators, In fact, it differs significantly from the conventional synchronous generators behavior which do not use PE interfaces. This paper examines the performance of the distance protection function in four different brand commercial relays in a Hardware in the Loop (HiL) environment with diverse type of faults and scenarios. The tests reveal the strengths and weaknesses of the relays. The results shown in this paper can be used as an overview of the actual protection devices performance in the present and forthcoming scenarios. The work is part of the EU project MIGRATE dealing with Massive Integration of Power Electronic Equipment. |
