Transfer function of the voltage sourced inverter

Nouri, H.; Davies, T. S.; Mukhedkar, R. A.

Abstract

This letter offers a state space representation of a voltage sourced inverter that forms the building block of modern flexible ac transmission systems (FACTS), such as STATCOM, SSSC, and UPFC. The representation includes consideration of the output phase, firing angle, and the conduction period. This model is used to devise a control algorithm of the dc link voltage and the output voltage. The concepts are demonstrated with a case study using PSCAD and MATLAB.

• Additional Information: Additional Information : This paper describes the state space representation of the voltage sourced inverter that forms the building block of modern Flexible AC Transmission Systems (FACTS), for devising the control algorithm of the dc link voltage and the output voltage. The method can also be used for inclusion of FACTS Devices in Power Flow solution. The outcome of this work has been exploited by Areva (Staffs, contact Dr R Mukhedkar) for its robustness, reliability and applicability to HVDC commercial projects.
