Interphase power controller adapted to the operating conditions of networks

This paper introduces a new family of interphase power controllers (IPC) for which the useful portion of the P_r-δ_sr characteristics are shifted as the power transfer level is increased. Thus, the power characteristics of a specific IPC application can be adapted to the operating conditions of the power network. The response of the IPC is compared to those of the two conventional technologies used in building it: the phase-angle regulator; and series compensation. It is shown how the natural response of the IPC regulates active power passively, without the need for control action. Also, reactive power can be controlled independently of active power slowing for better voltage control. The new IPC retains the inherent qualities of previous IPCs
