A Protection Method For An Electrical Collection System

Abstract: The present disclosure relates to a method for protecting an electrical power collection system comprising an electrical grid being electrically coupled to an electrical branch, the electrical branch comprising a plurality of switches for connecting or disconnecting the electrical branch at respective positions on the electrical branch, wherein a distributed energy resource is electrically coupled to a node on the electrical branch. The method comprises: detecting a fault occurrence on the electrical branch based on a monitored voltage and/or current of the electrical branch; limiting, based on the detecting a fault occurrence, a power flow from the electrical branch to the electrical grid; adjusting, based on the detecting a fault occurrence, a voltage and/or current on the electrical branch; determining a fault location based on the adjusted voltage and/or current on the electrical branch; and disconnecting a portion of the electrical collection system based on the determined fault location. The present disclosure also relates to a respective controller and system.
