【摘要】：介绍了风电机组模型的完整构成,阐明了各组成部分之间的复杂耦合关系,由此提出风电机组各个部分进行精细化建模所需考虑的因素,并指出现有简化模型忽略的因素及不足。在此基础上,设计了满足精细化要求的基于RTDS与Bladed的实时风电机组联合仿真平台。其中,Bladed的实时性由硬件测试模块保证,将风模型、气动模型、机械部分模型、变桨系统模型和偏航系统模型建立在Bladed中,将风电机组电气部分模型和控制系统模型建立在RTDS中,以发电机转子运动学方程作为机电耦合快、慢时间尺度之间的接口,并借助于PLC实现Bladed和RTDS之间的通信。在此基础上,按照实际机组控制系统架构构建了主控制器和变流器控制器硬件在环的联合仿真,最后通过多组硬件在环仿真充分展现了实时联合仿真平台的独特性能。
[Abstract]:The complete composition of wind turbine model is introduced, and the complicated coupling relationship between each component is clarified. The factors that need to be considered in the detailed modeling of each part of wind turbine are put forward. On the basis of this, a real-time wind turbine simulation platform based on RTDS and Bladed is designed, in which the real-time performance of Bladed is guaranteed by the hardware test module, and the wind model is designed. The pneumatic model, mechanical part model, variable propeller system model and yaw system model are built in Bladed. The electric part model and control system model of wind turbine are built in RTDS, and the rotor kinematics equation of generator is used as electromechanical coupling fast. The interface between slow time scale and the communication between Bladed and RTDS is realized by means of PLC. Based on this, the hardware simulation of main controller and converter controller in loop is constructed according to the structure of actual unit control system. Finally, the unique performance of the real-time joint simulation platform is fully demonstrated by multi-group hardware in-loop simulation.
