The present invention provides a mixed type unified power flow controller, which comprises a reactor unit, a capacitor unit, a first converter, a second converter, a series transformer and a shunt transformer. The reactor unit and the capacitor unit are connected in series with a power transmission line. The two ends of a reactor are connected in parallel with a first switching device. The two ends of a capacitor are connected in parallel with a second switching device. The first converter and the second converter are connected. The other end of the first converter is accessed to the series transformer. The other end of the second converter is accessed to the shunt transformer. A winding on the other side of the series transformer is connected with the power transmission line. The above winding on the other side is connected in parallel with a third switching device. Compared with the prior art, the mixed type unified power flow controller significantly reduces the required capacity of the converter, saves the cost and realizes the current limiting function at the same time.
