Problems of voltage rise in new Commissioned High voltage 220kv singa -kassala Transmission line

Abstract

The new high voltage 220kv transmission line which Originates from singa substation to kassala new substation – is considered as long transmission line of length 391.9 km. It is commissioned to improve the electrical reliability in Eastern grid. But unfortunately there appeared a problem of voltage rise in the line . the aim of this thesis Is to investigate and suggest solutions to the voltage rise problem so as to keep the voltage within standard limits. The data is collected from Sudanese Electricity transmission line Company (SETC) , and analyzed by using MATLAB program A static var compensation (SVC) is suggested for the solution of this problem . Finally a conclusion and recommendation is made.
