A New Directional Algorithm-based Approach to Fault Localization for Distribution Networks with High Penetration of Photovoltaic Systems


International audienceAbstract—Traditional fault location and isolation system inFrench distribution network uses nondirectional overcurrentbased fault locators and remotely controlled switches. Althoughstatistics have proved its effectiveness, the rising integration ofdistributed energy resources has considerably challenged thereliability of this system. The objective of this research is todevelop a new directional algorithm that can be integrated intothe existing fault indicators in order to address issues related tothe connection of new distributed generations. The algorithmuses the phase angle of the prefault voltage as reference quantityand that of the negative sequence current as operating quantity.The proposed technique is then deployed to develop a new faultlocation and isolation scheme. In order to evaluate theeffectiveness of the proposed scheme, a Control-Hardware-Inthe-Loop simulation platform which is based on OPAL/RTsimulator and ARM-based computers has been built
