The actual operation effect of the wind turbine online diagnosis system in the wind farm
Inner Mongolia Huadian Huitengxile Wind Power Company Huitengxile Wind Farm has a total of 120 wind turbines, including 30 Huarui FL1500 wind turbines, and 90 Gemei 850 wind turbines on December 1, 2007. The whole day was put into production.
After more than one year of operation, the mechanical faults of wind turbines are more to better grasp the operation status of important mechanical components of wind turbines. Inner Mongolia Huadian Huitengxile Wind Power Co., Ltd. and Beijing Tangzhi Technology Development Co., Ltd. have started JK07460 wind power since 2008. Application cooperation of the unit online fault diagnosis system (hereinafter referred to as JK07460 system). JK0746. The core technology of the system is "general resonance-resonance demodulation fault diagnosis technology", including vibration and shock composite sensor technology, hardware information processing technology for resonance demodulation, fault impact monitoring analysis and diagnosis technology, vibration monitoring analysis and diagnosis technology and axial direction. Instigation monitoring analysis and diagnostic techniques. .
The airborne equipment of the JK07460 system is installed in the nacelle of the wind turbine, including vibration shock sensor, displacement sensor, airborne host, pre-processor and related connecting cables to realize information collection and preliminary diagnosis, and the collected information is wireless. Or wired to the central control room host computer. The fault diagnosis expert system software is installed on the main computer of the central control room to realize information collection, diagnosis reasoning, alarm output, data management and other functions, and can control the airborne equipment to realize on-board software maintenance and remote upgrade. A central control room host computer and fault diagnosis expert system software can perform diagnostic analysis and storage on data of multiple onboard devices.
After more than two years of on-site testing, the diagnostic system has withstood the test system of the severe cold weather in Inner Mongolia and has found several fault cases. According to the automatic alarm of the online fault diagnosis system and the data analysis report provided by Tang Zhi Technology, the Huitengxile wind field has solved the safety hazards of the wind turbine group in time for the maintenance and repair of some of the faults found.
Case 1 unit gearbox gear failure
On February 10, 2010, the Gl19 wind turbine frequently reported that the gearbox oil temperature was high and the oil pump motor failed. The Tangji Technology's JK07460 system analysis showed that the gearbox gears were seriously worn and the sun gear and the high-speed shaft secondary parallel gear had been Online automatic alarm. The maintenance personnel went to the site to check that the oil pump motor was damaged and the wind turbine unit resumed operation after replacing the oil pump motor. March 2, 201. Online fault detection system.
