Multi-sensor cooperative wind driven generator yaw brake pad wear detection system and method

Abstract

The invention discloses a multi-sensor cooperative wind driven generator yaw brake pad wear detection system and method. The system comprises a temperature measurement module, an alarm brake cable switching value detection module, an early warning brake cable switching value detection module, an alarm brake cable analog quantity detection module, an early warning brake cable analog quantity detection module, a PLC control module, a display module and a remote transmission module. The PLC control module is used for measuring the temperature of the brake pad through the preset temperature measurement module, meanwhile, information provided by the early warning brake cable switching value detection module, the alarm brake cable switching value detection module, the early warning brake cable analog quantity detection module and the alarm brake cable analog quantity detection module is researched and judged, the current physical state of the brake pad is comprehensively judged, and the information is displayed through the display module in real time and is transmitted to a wind power plant monitoring system through the remote transmission module, so that intelligent yaw brake pad wear detection based on cooperation of a multi-sensor technology is realized, defects of the brake pad are found in time, and the inspection accuracy and efficiency of the brake pad are improved.

Description

technical field [0001] The invention belongs to the technical field of wind power generator brake pad wear detection, and in particular relates to a multi-sensor cooperative wind power generator yaw brake pad wear detection system and method. Background technique [0002] As the largest power source in new energy power generation, wind power has become the main force in new energy power generation due to its advantages of being unaffected by sunlight and easy to install. The yaw system of the wind power generator is an important system to exert the efficiency of wind power generation. The wind measurement system adjusts the nacelle to the position aligned with the wind direction according to the wind direction and wind speed parameters, so that the output of wind power generation is optimal at this position, and the yaw system simultaneously Shoulder the function of stably aligning with the wind direction and adjust the cabin angle in real time. When the yaw system is out o...

AI Technical Summary

Problems solved by technology

After the brake pads of the yaw system are worn out over time, if they are not replaced in time, the normal operation of the yaw system will be affected. Complete failure is not conducive to the safe and stable operation of wind power generation. After the brake system fails, the wind turbine will stop due to failure, which will cause economic loss to the power plant and will indirectly increase carbon emissions for the society.

[0003] The existing wind power yaw brake pad technology has the following defects and deficiencies: (1) The remaining life of the yaw brake pad is completely manually identified. Potential safety hazards of wind turbine nacelle equipment; (2) At present, there is no automatic detection product for brake pads in the yaw system, and the use scenarios of yaw brake pads are different from other types of brake pads. In the limited space on site, at a limited inspection angle In this situation, the staff cannot clearly observe the use of the brake pads; (3) The detection method of the brake pads in other technical fields is single, and it is difficult to comprehensively evaluate the wear of the brake pads
