Trajectory sensitivity analysis is used to find the best places for installation of thyristor controlled series capacitors (TCSC) to improve transient stability of the power system. Based on the rotor angles of generators, an equivalent angle (δeq) is defined by determining accelerating and decelerating machines, and then using trajectory sensitivities of this angle with respect to the impedances of the transmission lines in the post-fault system, appropriate locations for placing TCSC will be found. Severity of the faults is also considered in this calculation. This method is applied to the IEEE 3-machine 9-bus test system to find the priorities of the transmission lines for installation of TCSC. Simulation with industrial software verifies the obtained results.
