Dynamic phasor model of wams enabled transient stability controller

This paper presents the dynamic phasor model of WAMS enabled transient stability controller. In general, when any disturbance is occurs in power system than it contains low frequency oscillations which have to damp quickly for system stability. Primary controls are not able to damp these oscillations. Secondary control with synchronized phasor measurement obtained through PMU as feedback is good choice for damping of such oscillations. Also, Dynamic phasor model of the system can directly take data from PMU and also linearized the system which makes tuning of the controller parameters easy. Due to this reason, dynamic phasor model of secondary controller with PMU data as feedback is present in this paper.
