Self-inspection method and device for hydraulic control turning system of generator rotor

A self-inspection method for a hydraulic control turning system of a generator rotor, comprising:

• establishing a length dimension relationship table among a plurality of hydraulic cylinders of the hydraulic control turning system;
• selecting a reference hydraulic cylinder and acquiring a reference length dimension when the reference hydraulic cylinder is located at a target working position, wherein the target working position is a position at which a turning pin corresponding to the reference hydraulic cylinder is inserted into an adapted hole;
• and
• performing, by the plurality of the hydraulic cylinders, a function inspection of a motion execution module in sequence based on the reference length dimension and the length dimension relationship table:
• moving to a turning limit position, and inserting the turning pin into the adapted hole and pulling out the turning pin from the adapted hole to determine that the hydraulic control turning system meets a first starting condition.
