Yatta’s Medium Voltage Network Analysis and Enhancement

Abstract

This paper presents analysis and proposes solution scenarios for Yatta city (Y.C.) electrical network which experiences maximum demand exceeds the main feeder capacity and an inferior power factor for the industrial loads of the acceptable range. The maximum demand of the first feeder is covered by proposing new interconnection points and the installation of alternative energy source of photovoltaic (PV) generation units. The power factor of the system was improved by installing capacitor banks for industrial loads. As a result of applied solution related to interconnection points, the total load demand was fairly distributed and the transformer’s life time is increased. Due to distributed PV generation, the utility capacity is also increased and the transformers’ life time is increased by 4-5 years. A Simulation model using ETAP is implemented and the network capacity and load flow are studied that verify the proposed solutions. The obtained simulation results demonstrate the technical feasibility of these proposed solutions.
