Abstract A new type of flexible AC transmission system (FACTS) technology is proposed in this study. A single-core three-phase transformer with tap changers is designed as a controllable transformer with small rated converters. The magnitude and phase angle of the output voltage of the controllable transformer are controlled simultaneously. Thus, real and reactive power of the controllable transformer can be controlled independently. A controller of the controllable transformer is designed to improve the transient stability of a single-machine-infinite-bus system using the direct feedback linearization method. The simulation results show the effectiveness of the proposed controllable transformer and corresponding transient stability enhancement controller.

Key words： keywords：Controllable transformer independent control of voltage magnitude and phase angle dynamic power flow control FACTS tap transient stability
