Patent number: 11326580Abstract: A system for controlling a generator rotor locking pin, comprising a fixed locking pin and a rotor formed with a locking hole, and further comprising a detection reference component synchronously rotating with the rotor and formed with a detection hole, the detection hole radially corresponding to the locking hole; an optical quantity detection component fixed with respect to the rotor; and a control component configured to output a first control instruction to a rotor driving component according to a position signal of the detection hole obtained by the optical quantity detection component. The detection hole is used as an object to be detected, so that the circumferential relative position relationship of the locking hole with respect to the locking pin can be accurately determined, to output the first control instruction to the rotor driving component, thereby accurately centering the locking pin and the locking hole along with the rotation of the rotor.Type: GrantFiled: May 3, 2018Date of Patent: May 10, 2022Assignee: JIANGSU GOLDWIND SCIENCE & TECHNOLOGY CO., LTD.Inventors: Endi Zhai, Hongfeng Li, Kang Li, Xingang Zhang, Ye Li

Patent number: 11162473Abstract: A control method for a hydraulic control turning system of a generator rotor includes: establishing a length relationship table between multiple hydraulic cylinders of the hydraulic control turning system; selecting a reference hydraulic cylinder; acquiring current lengths of the multiple hydraulic cylinders when the multiple hydraulic cylinders are located at error correction positions; and adjusting lengths of the other hydraulic cylinders corresponding to a next driving stroke to conform with the length relationship table. With such an arrangement, the accumulated dimension error between the hydraulic cylinders may be dynamically corrected during the turning operation, thereby ensuring that the turning pins are accurately aligned with the pin holes in the generator, and the corresponding turning operation is performed after the generator set is locked. Based on this, a control device for a hydraulic control turning system of a generator rotor is further provided.Type: GrantFiled: April 20, 2018Date of Patent: November 2, 2021Assignee: JIANGSU GOLDWIND SCIENCE & TECHNOLOGY CO., LTD.Inventors: Wei Cheng, Hongfeng Li, Pengyang Li, Endi Zhai, Xingang Zhang, Ye Li
