Simulink & Modeling of Multi-Machine Systems with STATCOM/UPFC

This paper shows the model of multimachine system with STATCOMandUPFC FACTS controllerin MATLAB and done the simulation this is quite similar to the real-world system, and analyse their response through simulation and MATLAB. The STATCOM andUPFC simulations demonstrate howthe voltage swing is dampened out and how the values of various UPFC parameters change. In this paper shows the simulation model of multimachine (3-machine 9-bus) system. Analysis has been done by connecting FACTS Devices (STATCOM & UPFC) one at a time devices at different locations when three phase fault occurs. Graphs are plotted for all locations with STATCOM& UPFC in MATLAB for angle $\delta$ w.r.t time in seconds.
