| 摘 要： | 根据生产、安装、调试双馈风力发电机过程中所积累工程经验,在实验室条件下,设计了一套双馈风力发电机物理-数学仿真平台,并在其上实现新型的LVPWM控制方法.该仿真平台利用MATLAB的外部接口技术,通过MODBUS总线将变流器、风力发电控制系统所实时生成数据整合起来,避免了SIMULINK模块只反映接口特性而无法反映器件内部特性的缺点.实验结果表明,变速恒频双馈风力发电机的动、静态特性都能真实地反映出来,验证了LVPWM控制的优越性,并实现了实验平台并网的设计目标.

| Abstract: | The design and implementation of a new semi-physical simulation platform on doubly-fed induction wind turbine was discussed.In the proposed simulation platform,a novel sensorless vector control method of DFIG was established.The simulation platform implements data integrity of convertor with dual-DSP as controller and wind power control system with PLC as controller through MODBUS.The simulation platform avoids the drawback of using SIMULINK module alone which merely reflects the specification of interface but not the component interior characteristics.The experimental results showed that the platform possessed excellent simulation characteristics,which can truly reflect the static and dynamic performance of DFIG. |
