Development of a digital model for Oman electrical transmission main grid

Abstract

This paper describes the development of a digital computer model representing the main electric transmission system in Oman. A commercially available DIgSILENT power system computation package is employed. A brief description of system is given, which includes generating units, transformers, transmission lines and loads. The system is connected with a number of internal industrial plants to exchange electric power in addition to the interconnection between Oman and UAE. The model is used to perform computer studies such as load flows, short circuit analysis, stability, transient responses, etc. The simulation results are used for evaluating system performance and strategic planning purposes. Sample results are presented to show the capabilities of developed model.
