Analysis on the Status Quo of On-line Condition Monitoring of Wind Turbines
In recent years, China's wind power industry has developed very rapidly, but the wind power industry is still a new industry in China, and the rise time is still very short. Due to the rapid development of the wind power industry, after the completion of a large number of wind farms, the lack of professional technical management means, wind farm wind turbines face many problems in the daily operation process. For example, wind turbine gearboxes, bearings, generators and other key equipment often fail, but can not be detected and judged in advance, causing huge losses to the wind farm. Therefore, an effective monitoring system must be used to monitor and evaluate the operation of the wind turbines, so that wind farm managers can better manage the wind turbines.
On-line condition monitoring is an emerging cross-over technology developed on large wind turbines. Due to the large size, high degree of automation and complex working conditions of wind turbines, it is necessary to ensure the safety and reliability of the work process. The online condition monitoring system provides real-time visibility into the health of the crew so that appropriate measures can be taken to avoid significant economic losses and social impact. Provide follow-up improvements and optimized designs for wind power equipment manufacturers to provide objective and effective data.
Only by ensuring the stable and reliable operation of wind turbines can we ensure the healthy and rapid development of wind power generation, so that the national energy conservation and emission reduction targets can be implemented.
Compared with the traditional power generation industry, the wind power industry has the following characteristics:
• From a geographical perspective, wind farms are often located in barren hills, deserts, seashores and even seas that are inaccessible to people;
• From the perspective of the operating environment, wind turbines have to withstand high temperatures to low temperatures, from sand to salt spray, and the natural environment is very harsh; China Wind Power Equipment Network
• From the perspective of maintenance strength, the wind power industry is still in its infancy, often lacking experienced maintenance personnel and mature experience; China Wind Power Equipment Network
• From the perspective of power generation efficiency, due to wind conditions, the annual
