Improve monitoring system of interconnected oscillation power system based on PMU technology

Interconnected power systems have a very important role between several countries, the conditions of interconnections are strict in order to ensure the good quality of energy transmitted or received. The majority of the technologies that have been installed for system monitoring are based on the SCADA system, the latter does not give good results in real time and the error deviation is significant. This paper proposes a solution for the supervision problem based on the SCADA system; by using PMU technology to measure multiple parameters both with better accuracy and in real time. To validate the proposed approach, the developed PMU based monitoring system is implemented using Simulink/Matlab. Then, its performance is tested by the power system Simulink model under different operating conditions.
