This paper deals the application of Generalized Average models of custom power device, dynamic voltage restorer (DVR) for power system transient's analysis within dynamic phasor approach. The dynamic phasor models of DVR are evaluated through simulation of realistic network model of 3 machines 9 bus WECC system. The continuous-time large signal models of DVR under a fault condition captured the phasor dynamics of key wave forms. We demonstrate that the increase transient stability and improve power quality response of dynamic phasor model of DVR, is closely hugged with the detail time domain EMTP simulation. Numerical simulation of phasor dynamics with larger size steps through solving differential equation is also faster than that of EMTP. Both EMTP and theoretical framework of dynamic phasor models has been simulated using Simulink/Matlab dynamic system modelling software. 2007.
