Abstract

This invention relates to one gear double feedback motor experiment analogue system and its method, which comprises wind analogue controller, alternating drag motor, DSP unit, volume collection unit, speed test unit and drive unit, wherein, it uses wind machine property for analogue by use of analogue controller for alternating drag motor operation without wind field environment for wind blow real work property and it gives the experiment great continence; the analogue controller sets rotation speed and torque.

Description

technical field [0001] The invention relates to an experimental simulation system of a wind power generating set, in particular to an experimental simulation system of a variable-speed constant-frequency wind generating set adopting a double-fed generator. Background technique [0002] At present, among the main wind power generation technologies in the world, variable speed constant frequency wind power generation technology is the most optimized technology and will become the development direction of wind power generation technology. The core part of the variable speed constant frequency wind turbine control is the excitation control of the doubly-fed generator. Debugging excitation control of doubly-fed generators on the wind turbine simulation experiment platform is an important link in the development of wind turbines. There are many disadvantages in conducting experiments directly on the wind turbine. First, the wind turbine system is relatively complicated. In additi...
