| Summary: | Based on the development trend of the next generation power system, a novel flexible excitation system is designed based on three-level voltage source converter, and a matching five-level DC chopping circuit is proposed. An analysis is made of the controlling mode and performance of two DC chopping circuits with excitation current 6-IGBT or 3-IGBT. A simulation model of flexible excitation system is built based on PSCAD. The feasibility of the flexible excitation system with proposed five-level chopping topology and the control performance advantage over conventional self-shunt excitation are analyzed and verified. |
