Abstract

The invention discloses a low-voltage and medium-voltage wind power generation simulation experimental platform, which includes a power distribution system, a medium-voltage asynchronous motor and a control system thereof, a coupler, a low-voltage double-feed asynchronous motor and a control system thereof, and an upper computer monitoring system, wherein motor controllers in the low-voltage and medium-voltage wind power generation simulation experimental platform all adopt four-quadrant back-to-back systems, and the two motors operate under an electric power generation mode, so that one platform can be used for simulating wind driven generators of two different voltage classes and types. The low-voltage and medium-voltage wind power generation simulation experimental platform can be used for providing an experimental platform for grid-connected power generation of low-voltage double-feed wind driven generators, can be used for providing fundamental hardware platform support for the correlation technique research for grid-connected power generation of medium-voltage cage type asynchronous motors, and provides experimental foundation for researching key problems in the low and medium voltage wind power generation.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to the field of wind power generation experiment simulation technology, in particular to an experimental platform for low-voltage-medium-voltage wind power generation systems. Background technique [0002] As an effective form of renewable energy utilization, wind power has attracted more and more attention in recent years. However, due to limited conditions, it is unrealistic to verify a large number of actual wind field experiments. In order to efficiently verify the system control strategy, software and hardware , It usually requires preliminary laboratory ground simulation experiment research on the wind power generation system, so the application of the wind power generation laboratory simulation experiment system was born.
