Design a Centralized Protection Scheme in Micro-gride Power Systems
Authors: , , ,
Abstract: Distributed generators is now widely used in electrical power networks, in some cases it works seasonally, and some types works at special weather conditions like photo voltaic systems and wind energy, and because of this continuous change in generation condition which requires adaptive protection system that can adaptive its setting according to generation changes , central protection unite can be used to control the active setting group of protection relay according to generation capacity, a proposed method for selecting suitable backup relay is used, which leads to decrease relays tripping time and increase system stability.
