摘要
为了保证风力发电系统并网点电压稳定,以及实现无功功率补偿和功率因数校正,研究了基于静止无功发生器(SVG)的直驱永磁同步风力发电系统控制策略。建立了风力涡轮机、直驱永磁同步电机以及PWM变换器的数学模型,给出了各个接口变换器的控制策略以及无功电流检测技术。搭建了系统仿真平台,对研究的控制策略进行了仿真验证。
In order to guarantee the stability of the grid-connected voltage of wind power generation system,and achieve reactive power compensation and power factor correction technology,this paper studied the control strategy of direct driven permanent magnet synchronous wind power generation system based on static var compensator(SVG). The mathematical models of wind turbine,direct drive permanent magnet synchronous motor and PWM converter were established,and the control strategy of each interface converter and the technique of reactive current detection were presented. Finally,the simulation platform was built up,and the control strategy was verified by the simulation.
