Engineering - Power Engineering

In 1999, after the war in Kosovo, new developments took place affecting the electrical infrastructure, the same as other infrastructures in Kosovo. Households began to concentrate in the city and its suburb areas. This situation led to an increased demand for electric energy supply. On the other hand, the existing network was not designed to respond to such a flux of increased of customers.
This Capstone Project addresses an important problem regarding the power quality which is very common in Kosovo. It describes the context of power quality in distribution systems and deals more specifically with the corresponding diagnostics and implementation. It develops a precise and effective technique and method for the analysis how to improve a quality of electrical energy in Kosovo. The challenge of this project was to upgrade the existing design of network, and bring and build a new design of distribution system electric energy in Prishtina, saving energy which is being lost in distribution networks and improve the stability of particularly the electrical energy in Prishtina area.
This project involves technical and managerial prospects for solving the problems which are facing KEK employees and the customers in northern Prishtina. Moreover, the project provides experiences from other countries for making comparison with those in Kosovo.
The distribution network situation during 90’s in Kosovo was as a status quo. Due to the political situation there was no interest to invest in Kosovo. This resulted in gradual deterioration of the distribution network area.
This project based on the very latest studies, on increasing the reliability of quality of power energy supply up to the last customer. This project also considers the reduction of technical losses. The main goals of this project concerns the need for increasing the high level of voltage, necessary number of lines, substations and improve low voltage networks.
If it is possible to establish a scale of human needs, giving importance to the achievements of modern time and the way of living of modern human being, then for sure the electrical energy would take one of the top positions.
