Rotary power flow controller performance in power systems part II - RPFC performances in a transmission corridor

This part II of the work proposes the performance study of the RPFC operating in a two-line transmission corridor. The part I has presented the RPFC model and its implementation in SPS/Matlab. The present paper presents the simulation results of the RPFC operating in the corridor during the post-contingency period, when one of the two lines is out of service. From the RPFC model and the RPFC control system, derived in part I, this paper first determines the model of the electrical corridor equipped with the RPFC, and then implements the entire model including the RPFC control system, in the SPS/Matlab. The obtained results provide the behavior of the RPFC, as well as that of the corridor during the post-contingency period. The work analyzes, among other parameters, the influence of the RPST number of poles on the RPFC performances. Finally, the utilization of the RPFC, associated with the shunt capacitive compensation, allows restoring the post-contingency power flow conditions to be equal to those of the pre-contingency period.
