Stability Analysis of Online Power System with Wide Area Measurement System Using Matlab /Simulink

Wide-Area Measurement Systems (WAMS) provide the opportunity of utilizing remote signals from different locations for the enhancement of online power system stability. However, in wide area power system resulting from large extension and interconnection with neighbor grids, classical systems based on local independent measurements and decisions are not able to consider the overall power grid disturbances and then they are not able to avoid the blackout. The advanced measurement and communication technologies in these systems may provide better ways to detect rapidly these disturbances and protect the overall grid from the propagation of the fast-cascading outages. Indeed, the observability of the wide area power system dynamics becomes feasible through the use of these recent developed technologies. Using wide area real-time synchro-phasor measurement system based on Phasor Measurement Units (PMUs), different types of wide area protection, emergency control and optimization systems can be designed and implemented.
