Summary This paper deals with the stability analysis of a rotary power flow controller (RPFC). RPFC is a newly presented flexible alternating current transmission system device based on the rotary phase shifting transformer (RPST) configuration. This device comprises a shunt and a series transformer and two RPSTs. In this paper, a linear model is developed for RPFC in the dq‐reference frame. The model includes two RPSTs, shunt, and series transformers. Stability of the device is studied using eigenvalues of the state matrix. Effects of system parameters such as resistance, reactance, and phase difference of the shunt and series transformers and RPSTs on stability are investigated using eigenvalue sensitivity analysis. Simulation results using PSCAD/EMTDC software and analytical results based on eigenvalue analysis are presented to evaluate effects of different parameters on stability of RPFC.
