本文基于现有主流风力发电系统的一些不足,提出一种新型变量泵控定量马达的风力发电系统。该系统采用主调变量泵变量机构,比例调速阀从旁协助的复合调速方法,以达到发电机稳频发电的目的。根据系统数学模型和参数,进行Matlab仿真研究,经试验调试表明,本系统在风速的变化下,可实现马达转速稳定,保证了发电频率的稳定性。

Based on shortcomings of existing mainstream wind power generation system,this paper presents a new type of wind power generation system with constant-displacement motor controlled by variable-displacement pump variable.The system uses the main variable variable pump variable mechanism,proportional speed control valve from the side to assist the composite speed control method to achieve the purpose of generator frequency stabilization.Matlab Simulink research is built on the foundation of the system mathematical model and parameters.The test shows that the system can keep the stability of motor rotating speed and the power generation frequency under a shift in wind speed.
