摘要
针对目前风力发电系统中风机的变速定桨距、变速变桨距等运行方式,介绍了与各种运行方式所对应的控制策略,并详细说明了采用这些控制策略后对风机运行的影响.概括了各种控制策略的选择方法,即针对风机的不同运行方式应采取必要的控制策略来满足风力发电系统的运行要求,尽可能多地捕获风能并将其转换为电能供给电网.进一步明确了风力发电系统中风机的运行控制方法,进而为风力发电主控系统和变流器系统的设计研究提供参考.
In this paper,the different current wind turbine operation modes involving variable-speed fixed-pitch,and variable-speed variable-pitch and their control strategies are introduced.The impact of using these control strategies is also indicated.Finally,this paper suggests the reasonable selection of various control strategies,that is,the adoption of the right control strategies corresponding to different wind turbine operation modes to satisfy the requirements of wind power generation system,and capture the wind energy and convert to grid as much as possible.
