不将得到的实例作为一个对象添加到页的分层服务器控件树中，而将其作为非用户界面( ui )变量声明来对待。 - First , variable speed constant frequency wind energy convertion theory is described in this paper , then presents a review on the development of wind turbines control and the main types of generator and static converters used to interface variable speed wind turbines to the electric grid . then discuss main circuit constructure and advantage of direct drive wind energy conversion system and introduce pitch - control method for wind power traction and electric power stability . simply aerodynamic characteristic of the turbine is analysised and permanent magnet synchnonous generator math model is established . to convert the variable frequency electricity into utility grid , back to back four - quadrant pwm - vsi is used and three typies of control strategy is presented to capture the maximum wind energy and transmit energy . then simulation is implemented to test the control strategy . in the following chapter a simple ac - dc - ac converter with a dc - dc boosting chopper is proposed to transmit the wind energy into electricity energy and two control strategy is presented
建立了永磁电机和变流器的数学模型,针对双pwm变频器的特点提出了三种控制策略对变流器进行控制,通过变流器交-直-交的变换,将发电机发出的变频变幅值交流电转化为可用的恒定频率的交流电,通过pwm调治能使其输出功率因数为一,并且该控制系统功率因数为可调,能在特殊情况下同电网交换一定的无功功率,并通过对变流器的控制实现了最大风能俘获的功能。最后采用matlab / simulink进行了仿真,取得了良好的仿真效果。在风力发电系统中,采用先进的最大功率俘获算法,能有效的从风中获得最大的能量。
