Application of Single Pole Auto-Reclosing in Medium Voltage Distribution Networks for Improving Integration of Distributed Generation

This paper is divided into three parts. The first part presents a bibliographical survey about the advances to date in the area of protection of medium voltage (MV) distribution networks with distributed generation (DG). The second part discusses the transient stability of distributed synchronous generators, and the application of single pole auto-reclosing (SPAR) scheme in MV distribution networks. In the third part of this paper, dynamic simulation studies are performed and presented in order to evaluate transient stability of DG during three-phase and single-phase-to-ground faults. Additionally, results of simulation of the SPAR scheme applications on a MV distribution network with DG are presented. For this investigation, a MV test feeder with DG units has been used, and studies have been performed based on a digital computer simulation approach
