Control scheme of a superconducting synchronous generator applied to a grid-connected wind power generation system

Wind power generation system is a promising area of application of a superconducting synchronous generator (SCSG). A voltage sourced frequency converter connected to the stator winding of the SCSG and a DC-DC converter for the exciting current are needed for wind energy conversion. This paper describes the operation and control scheme of a superconducting wind power generation system (SCWPGS). The SCSG, voltage sourced frequency converter, and DC-DC converter are modeled and controllers of converters are designed in a power system computer aided design/electromagnetic transients including DC. This paper shows the dynamic performance of the SCWPGS with the proposed control system. The designed control system for the SCWPGS in this paper will possibly be applied to the actual system.
