Patent ID: 7002259

Claim:
A method of controlling a number of mechanically coupled electrical generators connected to a common rotor of a wind turbine, comprising: testing (at block 206 ) to determine if a rate of increase of wind speed is above a high rate limit for a number of generators connected online to a utility line; adding (at block 208 ) one generator to said utility line, upon a condition that said rate of increase of wind speed/load is determined to be above said high limit for said number of generators online; determining (at block 210 ) if a maximum number of generators are connected to said utility line; and, maintaining a region 3 run loop by modulating torque (at block 318 ), upon conditions that (1) said maximum number of generators are connected to said utility line (block 210 ), (2) no loads are above set limits (block 314 ), and (3) power is not below an adjustment threshold (block 316 ).
