Abstract
- Basic operational concepts of the single current source converter (CSC)-based STATCOM are studied in this paper. The space vector modulation scheme is adopted to control switching functions of the CSC. Capitalizing on anticipated new switch technology, the reduced-size LC filter is examined and design guidance is given. A filter current compensation method to reduce the error between command and response current is proposed under steady-state operation condition by use of phasor analysis. A loss compensation control is introduced that allows operation without a charging converter to maintain a desired value of current through the dc inductor. A DSP-based lab model is built to validate the concepts of the space vector modulated STATCOM and the control scheme proposed in this paper. The experimental results are satisfactory in that a low distortion line current results for steady-state operation. [Copyright &y& Elsevier]
