Voltage-source matrix converter as a controller in flexible AC transmission systems

This paper shows that the voltage-source matrix converter has all the fcatures of an asynchronous intertie, namely (1) frequency changing capability, (2) 360" phase shift range, and (3) bi-directional real power transfer. In addition, it has the cap#abilitiesfo r: (4) series line reactance compensation using a complex conjugate property, and (5) static VAR compensat,ion. Series reactance compensation gives rise to high sync:hronization power which improves transient stability. The matrix converter also has the flexibility to control both the transmitted real power and, independently, the reactive power flows at the sending-end and receiving-end of the transmission line.
