Abstract :
This paper shows that the voltage-source matrix converter has all the features 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 capabilities for: (4) series line reactance compensation using a complex conjugate property, and (5) static VAr compensation. Series reactance compensation gives rise to high synchronization power which improves transient stability. The matrix converter also has the flexiblity to control both the transmitted real power and, independently, the reactive power flows at the sending-end and receiving-end of the transmisson line
