With the development of urbanization, environmental problems are becoming more and more prominent, the supply of traditional fossil energy such as coal is getting tighter, wind power, as a non-polluting, low-cost power industry, power generation is very environmentally friendly, and wind energy contains a huge amount, so it is gradually gaining the attention of countries around the world.
At the same time, due to the application of modern new technologies in the manufacturing, control and management of wind turbines, wind power generation has become one of the most mature technologies and the most promising conditions for large-scale development and commercialization among new energy sources. By replacing coal power generation with clean energy generation, it can effectively reduce coal consumption and CO2 emissions.
A wind turbine, which can be referred to as a wind turbine, is one of the necessary conditions to constitute a wind power plant and is composed of three main parts: the tower, the blades and the generator.
In addition, it also has automatic windward steering, blade rotation angle control and monitoring and protection functions. The wind speed must be greater than 2 to 4 meters per second (depending on the generator), but the wind speed is too strong (about 25 meters per second), and when the wind speed reaches 10 to 16 meters per second, it reaches full capacity.

Since each wind turbine can operate independently, each wind turbine can be regarded as a separate wind power plant, which is a decentralized power generation system.
Since wind turbines are relatively large in size and have many components, regular in-service inspection of each component is necessary to ensure their normal operation.
CCSI has a complete set of inspection solutions for in-service NDT of wind turbines. It can solve the defects and weld detection of wind turbine tower, pitch bearing, blade, main shaft, etc., to the defects and stress detection of various bolts.
The tower is the main bearing structure of wind turbine, and the quality of the tower weld will directly affect the tower bearing strength, so it is necessary to test the weld of the wind turbine tower.
At present, most of the weld seam nondestructive testing of tower in service is carried out by means of conventional ultrasonic testing by means of ropes suspended at high altitude or by building tower escalators. Considering the safety of special high-altitude workers and the low efficiency of conventional ultrasonic methods for inspection, CSCI introduces a set of automatic inspection solutions.
