Abstract

This paper studies the role of controllable series compensation device in the control of critical line powerflow. Through the establishment of the circuit model for the transmission line with controllable series compensationdevice

the power equations are developed; and the power operating range

active power and reactive power curve aredrawn by using analytical methods. Through further analysis

the effect of UPFC plus fixed series capacitor on thetransmission power is analyzed. After economic analysis

the optimal investment scheme of UPFC plus series capaci-tor solution is given. Through the analysis of the key lines in Jiangsu Power Grid

the rationality of the UPFC plus se-ries capacitor scheme is clarified and the validity of the solution procedure is verified.
