Rehabilitation of the electric power distribution Grid in Taffouh town

Abstract

Electric Utilities seek to meet the power demand and reduce the losses of the electrical network while satisfying a number of constraints. During heavy loadingconditions, so that the voltage variations around 10%. The power loss must also be kept as low as possible and a value around 10% or even less would be acceptable. Power system operators work hard to keep the system working around the nominal values to ensure proper functioning that ensures lower power loss and guarantees a continuity of service that is crucial to private and public sectors alike. This study investigates thoroughly the electrical distribution grid of the Taffouh Town where the electric grid in Taffouh town suffers from many problems technically and distribution suffered by the rest of the cities and villages of the West Bank That's after getting the information necessary to help rehabilitate this grid through the use several analytical programs and device, E-TAP software and Vega 78(power analyzer device). The suggested measures used for rehabilitation are the reactive power compensation using capacitor banks and replacement some of transformer and also the replacement of old wires and cables with new and adequate ones. The study will handle each of these measures collectively; The results obtained will be tabulated, graphed, analyzed, and compared with the values of the current situation. The results have shown that the distribution grid of Taffouh need to be rehabilitated ; Where the network power factor was improved from 0.868 to 0.97, thus reducing 58% of total losses in network and achieving economic feasibility of the project to provide 1018837.25 NIS / year; as a result of improved power factor which cost 33620 Nis for the entire project and reducing voltage drop from 64.99 % to 32.77% for an entire system; highest voltage drop 2.24% of the bus voltage in project after rehabilitation .
