Power System Security and Contingency Analysis of the transmission grid of Uganda.

View/Open

The power system of Uganda is dynamic, subject to changes that can adversely affect it. The power system of Uganda has suffered some blackouts overtime and since the major source of power in Uganda is electricity, the blackouts result into serious financial implications. When power loss occurs, production of goods and services is slowed down or even stopped. In line with the National Development Plan and vision 2020, Uganda is setting up 22 industrial parks to increase the production capacity of Uganda. With these, power network infrastructure is being expanded necessitating an analysis of the power system to determine power system security.The study was carried out using contingency analysis in the Digsilent power factory environment. Both the current and future transmission network were modeled and analyzed for N-1 contingencies such that the network retains stability in the event of a contingency. The results showed that the current transmission network is stable and N-1 contingency levels are satisfied. However, with the planned modifications, the network does not converge for N-1 contingency levels for all elements with some lines in the base case. Interventions such as increasing the number of lines and addition of lines were designed to ensure proper loading in the base case as well as ensuring N-1 contingency levels in the event of a contingency.
