General wind power converter experimental platform based on double-fed wind driven generator

Abstract

The invention discloses a general wind power converter experimental platform based on a double-fed wind driven generator. The experimental platform comprises an electric motor, a gear mechanism and a double-fed asynchronous wind driven generator, wherein the electric motor is in transmission connection with the gear mechanism, and the gear mechanism is in transmission connection with the double-fed asynchronous wind driven generator. During test experiments of different types of wind power converters, the connection mode of a rotor winding of the double-fed asynchronous wind driven generator is correspondingly changed according to different types of wind power converters, thus, three different wind power converter experiments are carried out only by the general wind power converter experimental platform, and the building cost of the test platform is greatly reduced; and during the test experiments of different types of wind power converters, the corresponding wind power generator is not needed to replace, the experiment preparation time is shortened, and the running efficiency of the wind power converter experimental platform is greatly improved.

Description

technical field [0001] The invention relates to a wind power converter test platform, in particular to a general wind power converter test platform based on a doubly-fed wind power generator. Background technique [0002] When testing the wind power converter on the traditional wind power converter experimental platform, it is necessary to match the corresponding wind power generator according to the type of the wind power converter. The test experiments of squirrel-cage asynchronous wind power converters, wound synchronous wind power converters, and doubly-fed asynchronous wind power converters all require the cooperation of corresponding wind power generators; , the corresponding wind turbines are incompatible with each other. Therefore, the wind power converter experiment platform needs to prepare a variety of wind turbines to adapt to the experiments of various wind power converters, which undoubtedly increases the construction cost of the experiment platform. In addit...
