Analyze Contingencies Present in the Transmission Systems Case of North?West Grid of Tanzania

Janeth Tesha


Abstract: The northwest grid network of TANESCO (Tanzania state power company) suffers the stressful condition caused by factors such as worst climate condition affecting hydropower source (which is 75 % of the total generated units), an over exploitation of the existing transmission system and less or no number of new power system projects, together caused lack of reactive power sources into the system resulting in voltage instability. Research carried in this work observe and record some indication of the severe condition existence, aiming to find methods to relieve this system from voltage instability. The Contingencies present in the Transmission System in the North West Grid of Tanzania were analyzed. And it was found that power faults contribute a lot to the grid outages and therefore the losses. The study proposes that there be Power Generation Capacity Reinforcement and Transmission Line Reinforcement. However the study was limited to hydropower sources only in the country (northern and southern). The research recommends that proper selection, location and economic analysis are needed further to provide the most efficient performances of power system
