Application of Matrix Converter for Power Flow Control in a Transmission Line

This paper presents a new concept of power flow control in a power system transmission line. Proposed controller, a new FACTS device, consists of two power transformers and a matrix converter as an active control unit. Transformers changing a number of phases from 3 to N and again from N to 3 and an NxN matrix converter is located between them. A special control strategy of such matrix converter has been developed, which enables to control a transmission line current. This paper presents an analysis of an idealized controller with the 6 x 6 matrix converter in frequency domain, just to test new idea.
