Wind power generation simulation system based on brushless synchronous generator

Abstract

The invention relates to a wind power generation simulation system based on a brushless synchronous generator. In the technical scheme, a frequency converter 2 is connected with a power grid 1 and is used for controlling an electric motor 3 of a simulation blade, a brushless synchronous wind power generator is connected behind the electric motor 3, the current from the generator flows to the power grid 1 through a full-power rectification inverter circuit 5 based on AFE, and the whole system forms a closed-loop circuit. A control system 6 is used for controlling the frequency converter 2 and the full-power rectification inverter circuit 5 so as to complete the system control. The simulation system adopts the brushless synchronous wind power generator without slip ring or electric brush, thereby improving the system reliability and safety. Simultaneously, due to the full-power rectification inverter circuit based on the AFE, the simulation system not only can eliminate the higher-order harmonics and improve the power factor, but also can not be affected by fluctuations of the power grid, thereby achieving good dynamic properties.

Description

technical field [0001] The invention belongs to the field of wind power generation simulation systems, and relates to a wind power generation simulation system, in particular to a wind power generation simulation system based on a brushless synchronous generator. Background technique [0002] Since our country entered the research and development stage of wind power technology, wind power technology has made great progress and improvement in both scientific research and design and manufacturing, but the fact now is that the core technology of wind power has not been adopted by our country. As far as we know, the level of wind power generation is not high, so it is necessary to strengthen the research of wind power technology, but there are not many simulation systems for wind power generation in China, especially there is no wind power generation simulation system based on brushless synchronous generators. Moreover, due to the limitations of wind farms, wind turbine test inv...

Problems solved by technology

[0002] Since our country entered the research and development stage of wind power technology, wind power technology has made great progress and improvement in both scientific research and design and manufacturing, but the fact is that the core technology of wind power has not yet been adopted by our country. As far as we know, the level of wind power generation is not high, so it is necessary to strengthen the research of wind power technology, but there are not many domestic wind power simulation systems, especially there is no wind power simulation system based on brushless synchronous generators

Moreover, due to the limitations of wind farms, wind turbine test investment costs, site conditions, etc., the actual research on various characteristics and control schemes of wind power generation systems is greatly restricted.
