Abstract:
Oil Industry has become the most important part of Sudan Economy and is playing the main role for country incomes.
White Nile Petroleum Operating Company (WNPOC) is one of the Oil Operating Companies which has been producing crude oil since 2006; one of its running fields is Mala fields which comprise the following sub fields:
Mala Main,
Mala North,
Mala East and
Mala South East.
When these fields were commissioned and started-up, there appeared continuous power outages in the Electrical Distribution System. One of the causes of these outages is due to unsatisfactory performance of protective devices. As a result of that, continuous power interruptions and oil production deferment have taken place.
The objective of this project is to investigate the problems of the unsatisfactory performance of protective devices in the aspects of relay settings and enable of additional relay features. The investigation is done by using reputed software named “Electrical Transient and Analysis Program (ETAP)”.
The Data Gathering and Single Line Diagram (SLD) were established and ETAP software was used to model the SLD and entered required data of the equipment and then verified, after that have to run Short Circuit Study and Relay Co-ordination study and finalized with analysis and discussion for the obtained outcomes and results.
