“…From equation 1, (2) and (3) .. 4If now difference between the system angular frequency and the angular frequency of the mass 2 is given as .…”

“…Series compensation increases the maximum power that can be transmitted, & lowers the effective reactive power (I 2 X) loss. There are many methods proposed in literature for SSR mitigation [2][3] [4][5] [10] [11] etc. This paper proposes that SSR can be mitigated with a proper gating pulse to TCSC.…”
