Abstract

Nowadays, wind energy is developing rapidly all around the world. There are many options of wind power generation and collection system configuration. DC wind farm collection grid is preferable due to its small size of passive components and better efficiency with high switching frequency. This paper studies the design and control of wind energy conversion system based on serial parallel LCC current output resonant DC/DC converter. LCC resonant converter has combined the advantages of the series resonant converter (SRC) and parallel resonant converter (PRC). It is found to be the suitable choice for multi-terminal DC micro-grid power transmission to interface multiple wind turbines. Design procedure for the LCC converter is explained and the analysis is verified with simulation results. Experimental work based on wind simulator is presented to verify the feasibility of the wind energy conversion system.
