Description

Technical Field

[0001] The present invention relates to the technical field of generator set detection, and in particular to a control system and a control method for a generator set stator and rotor internal inspection device. Background Art

[0002] Large hydroelectric generators are key operating mechanisms in the process of hydroelectric power generation. The stator is the main component of the generator. The iron core and winding are key components for the generator to generate a magnetic field and operate normally. The iron core includes slot wedges, corrugated plates, gaskets, and wire rods. The looseness detection of the stator slot wedges is the core to ensure the long-term and stable operation of the generator. For large hydroelectric generators, generator factories often use slot wedges and gaskets or slot wedges, gaskets and corrugated plates combined structures to reinforce the stator wire rods. However, with the long-term operation of the generator, the electromagnetic force of the wire rod continues to act, causing the deformation of the gasket or corrugated plate to gradually decrease, and then the slot wedge becomes loose or falls off, causing major safety hazards. Therefore, it is necessary to detect and maintain the looseness of the generator slot wedges during the maintenance plan to ensure the normal and safe operation of the generator.

[0003] For example, the control system and control method of the internal inspection device of the stator and rotor of a generator set, whose authorization announcement number is CN202410706805.1 and whose publication date is 20241001, includes a communication network established based on Ethernet, and a remote control base station, a controller module, a universal motion drive module, and an information acquisition module. The remote control base station sends control instructions to the controller module through a wired local area network, and receives the status information of the internal inspection device body and the detection results of the generator set for display. The universal motion drive module carries the working tool to control the circumferential, axial, and normal motion of the stator and rotor of the generator. The information acquisition module collects data in real time for detection and control, and executes the narrow gap inspection process, the slot wedge tightness process, and the generator stator and rotor surface cleaning process; the method includes: setting the control process, checking the surface defects of the stator and rotor, judging the tightness of the slot wedge by knocking sound, visually displaying the simulation model, and the detection and cleaning process.

[0004] Although the stator and rotor internal inspection devices mentioned above and in the prior art can realize the inspection of the stator and rotor, the subsequent processing of the inspection data is a slow process, and the problems of the stator and rotor cannot be quickly analyzed, resulting in workers being unable to repair the inspection device with problems in time; at the same time, the inspection device only has the function of detection, and cannot process the stator and rotor with problems.

[0038] The image processing unit is used to process the image data detected by the built-in module, and the image processing unit performs enhancement and optimization processing on the image through a frequency domain enhancement method;

[0039] The data calculation unit includes two types: spectrum contrast model and image contrast model.

[0040] The spectrum comparison module is established by using the sound spectrum comparison technology, and is used to compare the sound data processed by the sound processing unit with the sound data of the stator non-destructive knocking test stored in the data storage unit;

A control system for the internal inspection device of the stator and rotor of a generator set according to claim 7, characterized in that: A pinhole camera (12), a sound collection module (13), a piston cylinder (14) and a Bluetooth connector (15) are respectively installed on the outer wall of one side of the mounting plate (11) by means of bolts. The Bluetooth connector (15) is electrically connected to the pinhole camera (12) and the sound collection module (13) by means of wires. An air intake pipe (25) is plugged into the outer wall of one side of the piston cylinder (14), and the air intake pipe (25) passes through the groove (8). A piston rod (16) is plugged into one end of the piston cylinder (14), and a knocking head (17) is threadedly connected to one end of the piston rod (16).

10. A control method for a generator set stator and rotor internal inspection device, using a generator set stator and rotor internal inspection device control system according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Arrangement inspection device: The prepared built-in module is arranged on the rotor of the generator set, and the process is to fix the support plate (3) on the rotor by rotating the limit bolt (5); S2. Start the test: During the test, the servo motor (9) is started, and the screw rod (10) will slide on the double linear track (7) with the structure composed of the nut (19), the connecting rod (18) and the mounting plate (11). During the sliding process, the air inlet pipe (25) will inflate the piston cylinder (14), and then the piston rod (16) will rise with the knocking head (17). The raised knocking head (17) will knock on the stator, and then the sound collection module will collect the sound generated by knocking on the stator. At the same time, the pinhole camera (12) will shoot the stator and collect the image data of the stator. The subsequently collected data will be transmitted to the communication module through the Bluetooth connector (15). In addition, during the test process, the rotor can be controlled to rotate so that the built-in module moves in a circle, thereby realizing the detection of the stators at other positions in the generator set; S3. Data processing: The data received by the communication module will be transmitted to the processing module, and then the sound processing unit in the processing module can process the transmitted sound data, and the image processing unit can process the transmitted detected image data. The processed data will be transmitted to the data calculation unit, and then the spectrum comparison module can compare the sound data processed by the sound processing unit with the sound data of the stator non-destructive knocking test stored in the data storage unit. If there is a comparison result, it indicates that the stator is not damaged. If there is no comparison result, the stator is damaged. At the same time, the image comparison model first extracts the feature data processed by the image processing unit, and then compares the feature data with the stator non-destructive image data stored in the data storage unit. If there is a comparison result, it indicates that the stator is not damaged. If there is no comparison result, the stator is damaged; S4. Control and management: Based on the above detection results, the processing module will notify the workers to carry out maintenance through the communication module. During the maintenance, the servo motor (9) can be started, and then the screw rod (10) will slide on the double linear track (7) with the structure composed of the nut (19), the connecting rod (18) and the mounting plate (11). During the sliding process, the air source can be filled into the cover body 2 (24) and the cover body 1 (23) through the air supply pipe 1 (21) and the air supply pipe 2 (22). Then the cover body 2 (24) and the cover body 1 (23) will spray air to clean the stator.
