POWER SYSTEM SECURITY AND CONTINGENCY ANALYSIS OF THE TRANSMISSION GRID OF UGANDA
View/
Open
The power system of Uganda is dynamic in nature and is subject to various changes that can affect it negatively. It has over the last two years suffered from at least two major blackouts that have been attributed to various generation, transmission, distribution and load capacities problems on the network. The major source of power in Uganda is electricity and these blackouts result into serious financial implications for the government, investors and private citizens as well. This is because when a blackout occurs, production of goods and services is slowed down or even stopped. In line with the National Development Plan and vision 2040, Uganda is setting up twenty two industrial parks across the country to increase the production capacity of Uganda. With this, various new generation stations such as Isimba and Karuma have been set up, together with extra transmission lines. This implies a proper study to ensure power security needs to be carried out with a rationale of having a stable and reliable power grid regardless of the additional generation or electric load. The study was carried out using contingency analysis in the Digsilent power factory environment. Both the current and future transmission network with predicted load as of 2025 models were developed and subjected to the N-1 contingency criteria. At this level of contingency, the idea is to have a stable power network even in the event of loss of one system asset. Basing on the results from the network security and contingency analysis of the network as is, it can be conclude that the network is stable and N-1 contingency levels are satisfied. However, when additional industrial loads, generation stations and lines are added as predicted to be in 2025, the network does not converge for N-1 contingency analysis on some assets. Further examination of these results points out that that the violations occur on the Lira, Karamoja and Arua Industrial parks connected to Opuyo bus bar as well as Luzira and Mukono Industrial parks connected to Namanve bus bar. It can also be concluded that under the continuous loading case on some of the lines, the loading exceeded the overloading limit under contingency scenarios and as such require extra capacity. This therefore informs the transmission system planners which transmission lines need upgrade in terms of capacity or can be considered in the first phase of transmission lines expansion. This eventually offers an overriding method to maintain the system security so as there is high reliability and integrity in the power system. (1.069Mb)
