Description

Technical field: [0001] The invention belongs to the field of higher education instruments and equipment for wind power generation. It is used for the experiment and teaching of the two major wind power generator sets of permanent magnet synchronous and squirrel cage asynchronous, and can conduct experiments on the key components of the whole machine and the wind power generation system. Background technique: [0002] Most of the early wind turbines were squirrel-cage asynchronous wind turbines, which had the advantages of simple structure, low price, convenient maintenance, and large speed variation range, and were suitable for the development and application of early wind power generation. At present, the three types of generators with the highest market share in large wind turbines are doubly-fed induction generators, permanent magnet synchronous generators and electric excitation synchronous generators. Due to the advantages of high power generation efficiency, good rel...
