大型多功能风电机组主轴制动器惯性试验台的研制

Multi-functional inertia dynamometer for main shaft brake of large scale wind turbine generator

针对我国大型风力发电机组容量已达6MW,而现有风力发电制动器惯性试验台只能完成3MW制动器测试的问题,作者研制了可用于6MW大型风力发电机组主轴制动器测试的惯性试验台。介绍了该试验台的工作原理、结构及关键技术的解决措施。该试验台不仅可用于风力发电机组制动器测试,还可用于工业制动器、重型卡车制动器、船舶锚绞机制动器的测试,提高了设备的投资效益。初步实测表明,该新型试验台可以达到设计的功能要求。

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.
