CONTROL GEAR FOR ASYNCHRONIZED SYNCHRONOUS GENERATOR Russian patent published in 2002 - IPC

FIELD: electrical engineering; windmill-electric generating plants operating in parallel with ac mains. SUBSTANCE: control gear that functions to generate desired corrective signals is provided with coordinate converting units 13, 14, 18, 19, amplifiers 15, 22, multiplying units 16, 21, 23, adders 17, 20, 24, 28, 35, 41, cubing unit 25, nonlinear element 26, squarers 27, 34, square-root extracting unit 29, controlled electronic switch 30, voltage setting device 31, comparison gates 32, 38, voltage regulator 33, maximumcurrent setting device 37, current regulator 39, and stator current frequency control device 40. Corrective signals generated by control gear provide for voltage regulation in low-power ac mains in case of changes in wind flow capacity thereby improving active and reactive power control for windmill-electric generating plant. EFFECT: improved quality of active and reactive power control. 1 dwg
