Abstract:

The inertia dynamometer is an important test equipment for the main shaft brake of wind turbine generator system. Currently, the capacity of large-scale wind turbine generator system has already reached 6 MW in China, and existing inertia dynamometers can only complete the 3 MW or lower test. This article introduces the latest development of the inertia dynamometer for main shaft brake of 6 MW large-scale wind turbine generator systems. The working principle, structure and solutions for key technology of the inertia dynamometer are described. This inertia dynamometer system is not only be used for wind turbine brake, it is also used for industrial brake, heavy truck brake and marine windlass brake testing, thus increasing the investment benefit. Primary test results show that this inertia dynamometer fulfils functional requirements.

Key words: mechanical design, wind turbine generator, brake, inertia dynamometer
