Coordinated Control of Large Scale Offshore Wind Farms Integrating into VSC-HVDC System

Abstract:

VSC-HVDC has become prior transmission way in delivering off-shore wind power. This paper studies offshore wind system based on DFIG (Doubly Fed Induction Generator) wind turbine. The control strategy of the system during the normal and fault condition are studied. In the normal condition, the GSVSC are operated by controlling constant frequency, voltage and phases. During the fault condition, the GSVSC converted to limit current model and dc voltage link are controlled by DFIG-RSC converter. These control strategies are validated in good performance in PSCAD/EMTDC platform.
