New converter for interfacing PMSG based small-scale wind turbine with residential power network

This paper presents a new converter topology for interfacing a permanent magnet synchronous generator based variable speed wind turbine with a residential power network. The theory of wind energy conversion is analyzed first. Then an example of wind velocity distribution and normalized energy yield is discussed in order to formulate requirements for choosing a power converter. A new topology of an interfacing converter is analyzed and simulation results of a lossless model are presented. Simulation results of the proposed converter prove that its utilization in wind power applications is beneficial.
