BACK TO BACK CONVERTER COMPRISING OF EDLC AND WIND POWER GENERATION SYSTEM USING THEREOF

摘要

PURPOSE: A back to back converter including an EDLC and a wind power generation system applying the same are provided to reduce an amount of power loss by omitting a power conversion apparatus such as a DC/DC converter and an inverter. CONSTITUTION: A generator side converter(220) converts poly-phase AC power to DC power. An EDLC unit(230) stores all or a part of the DC power converted in the generator side converter. The EDLC unit outputs DC power in a predetermined size. A system side converter(240) converts the DC power transferred from the EDLC unit to AC power. A control unit(250) controls the system side converter using system side standard active power and system side standard reactive power.
