Abstract

The UPFC is the most powerful power flow controller recently, and because of the exchange of active power between the shunt and series parts, they have to be located at the same place. This paper presents a new concept to transmit power without the common dc link of the UPFC, which gives the possibility of the separated UPFC. The exchange of active power is through the existing transmission line but at a different frequency, which is independent from the fundamental frequency component. The results of steady-state analysis of the separated UPFC are also presented.
