New Protection Schemes for Ground Faults in Micro-Grids

Abstract:

In this paper,the protection schemes for phase-to-ground and multi-phase faults in micro-grids is proposed, accounting for the facts of new topology and operating characteristics of micro-grids.The definition of this protection schemes is to find solutions in a short term. For this reason the proposed solutions make use of traditional or commercially available protective switching and sensing devices, as well as automation techniques. Traditional technologies employed by this protection schemes can allow to find practical solutions to protect micro-grid feeders instead of a high number of inverted-interfaced generators resorting to different protection schemes ,and achieve minimum operating costs.
