Description
Summary:The Tunisian power system rely more on tie line power interchange. Unstable inter-area oscillations restrict power transfer between areas and may endanger the system security. In this paper we perform a study on the oscillation phenomena in the interconnected Tunisian power system and their detection by the global positioning system. The detection of the frequency is based on the equivalent relation machine rotor speed-terminal voltage angle. The placement of the phasor measurement units (PMUs) is optimized by the Recursive Security N Algorithm and several power exchanges events are simulated. The results of this paper can help solve some of the existing interconnection problems and demonstrate how to improve the operation of the overall system behaviour by phasor measurement technology.
