嵌入式控制在变速恒频风力发电系统的应用

Embedded Control in Variable-speed Constant-frequency Wind-power Generation

变速恒频风力发电技术因其高效性和实用性受到越来越多的重视,为解决实验室环境中模拟风电现场进行风力发电研究的原动机问题,提出了采用鼠笼式异步电机来模拟风轮机的方案。这里还构建了由3台变流器、3块DSP2407A控制板和2台鼠笼式异步电机组成的嵌入式风力发电系统实验平台,对模拟风轮机的电动机和鼠笼式异步风力发电机进行转差频率控制。最后对风轮机运行特性和风力发电机的并网运行进行了实验,实验结果证明,采用该系统进行风力发电系统实验研究是正确有效的。

Now many kinds of technologies applied to wind-power generation are in the ascendant,among which the technology of variable speed and constant frequency（VSCF） is getting increasing recognition for its characteristics of high-efficiency and practicability.The method of emulating wind turbine by squirrelcage induction motor is presented to solve the prime motor issue for the study of wind power generating system in lab.The reliable and integrated labora-tory experimental platform of wind power generation system is constructed.The experimental results verify the validity and feasibility of the model of VSCF wind power generation system platform in the lab.
