<P>PROBLEM TO BE SOLVED: To provide a generated power equalizing device using pitch angle control in all operation regions for equalizing output power in a wind farm having a plurality of wind power generators with pitch angle controllers, and to provide its method. <P>SOLUTION: A wind farm control device is provided for giving a set value to each pitch angle controller. it generates a wind farm output power command value *P<SB>go</SB>, calculates an output power command value P<SB>go-base</SB>for every wind power generator in accordance therewith, subtracts wind farm output power *P<SB>g</SB>therefrom to find a wind farm output power deviation *e, calculates an output allowance Pm for each wind power generator, calculates an output power compensation value P<SB>go-com</SB>for every wind power generator from the wind farm output power deviation *e and the output allowance Pm for each generator, and supplies a value obtained by adding it to the output power command value P<SB>go-base</SB>, as a gross output power command value P<SB>go</SB>, to the pitch angle controller for each wind power generator. <P>COPYRIGHT: (C)2007,JPO&INPIT |
