    ANALYSISAND IMPROVEMENT OF NABLUS ELECTRICAL DISTRIBUTION NETWORK BY ADDING A NEW CONNECTION POINT IN SARRA VILLAGE AND TWO TRANSFER SUB-STATIONS TO FEED THE NETWORK

    Lack of electric power sources is one of main problems in Palestine since the population increased dramatically and the required electric power exceeded the permissible limit. In fact, since the Israeli-Electric Company is almost the primary source of electricity, therefore the electric power are limited. The Palestinians suffer from a shortage of electric power due to increasing of electrical power demand, but Israel Electric Corporation does not keeping up with the increasing demand. Nablus also suffers from a shortage of electric power due to the existence of new buildings and the sharp increase of population. In addition, the total electric power supplied to Nablus from connection points has the capacity of 65 MW, but electrical loads reached their peak especially in winter. Consequently, North Electrical Distribution company (NEDCO) cuts off some loads from certain areas in Nablus network for periods of time that exceed an hour per day in order to reduce the pressure on the other connection points in the same electrical network because loads exceed the permissible limit. This leads to failure in electrical transformers as well as in transmission lines and devices. At SARRA connection point, which is one of the connection points of Nablus, the capacity of the substation is 80 MW, and the used capacity is 40 MW. In this study, the researcher aims to examine the analysis and improvement of Nablus electrical distribution network by adding a new connection point in SARRA village and two distribution sub-stations to feed the network. There, a distribution substation was added in two areas with a capacity for 20 MW to each substation, named: Nablus Al-Jadida and An-Najah National Hospital. In fact, the electric power capacity has been raised to 105 MW for the city of Nablus. In this study, the problem was solved considerably by providing new areas with electric power and redistributing the loads from other connection points located in the Nablus city, especially in the eastern industrial area, and new overhead and underground electric transmission lines have been established. The value of the electric capacity supplied from the connection points to the city of Nablus has decreased, and there is a possibility of future expansion and supplying areas in the future due to the presence of electric energy capacity at the new connection points, according to the results found in this study. Also, economic feasibility of the project was prepared and the initial cost value has been calculated.
