Control system and method of power generator rotor locking pin

Abstract

The invention discloses a control system of a power generator rotor locking pin. The control system of the power generator rotor locking pin comprises the fixedly-arranged locking pin and a rotor witha locking hole, and further comprises a detection standard part, an optical quantity detection component and a control component; the detection standard part and the rotor can rotate synchronously; adetection hole is formed in the detection standard part; the detection hole and the locking hole correspond to each other in the radial direction; the optical quantity detection component is fixedlyarranged relative to the rotor; and the control component outputs a first control command to a rotor drive component according to the position signal, obtained by the optical quantity detection component, of the detection hole. The detection hole serves as a to-be-detected object, and the circumferential relative angle relation of the locking hole relative to the locking pin can be accurately determined, so that the first control command is output to the rotor drive component, and thus the locking pin and the locking hole are accurately aligned along with rotation of the rotor. In addition, the aligning treatment efficiency is greatly improved by the scheme while the accurate aligning precision is obtained. On the basis, the invention further provides a control method of the power generator rotor locking pin.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a control system and method for a generator rotor locking pin. Background technique [0002] With the development of large-scale wind power generating units, it is more and more difficult to install the blades of the unit, and the way of installing the blades separately has gradually become a trend. During the individual installation of the blades, the hub of the generator set is required to perform rotational cooperation (that is, turning work) to cooperate with the installation operation of the blades. [0003] As we all know, during the single-blade hoisting process, the generator rotor needs to be locked at the same time. Usually, the locking pin is used to realize the locking between the existing barring system and the generator rotor. The locking pin is fixed on the fixed shaft of the generator, and a matching locking hole is provided on the generator rotor, ...

AI Technical Summary

Problems solved by technology

[0004] At present, the alignment of the existing rotor locking pins is mainly done based on the observation of the operator. There are inevitable deviations in the naked eye observation, it is difficult to ensure the accurate alignment of the locking pins and the locking holes, and the processing time of the alignment cannot be effectively controlled.

[0005] In view of this, it is urgent to optimize the design of the existing barring system to effectively solve the problem that the centering accuracy of the locking pin of the barring system cannot be precisely controlled, so as to ensure that subsequent operations such as blade installation can be carried out quickly and reliably
