摘　　要：基于RT-LAB仿真平台,分别搭建了永磁直驱风电机组的CPU仿真模型和CPU+FPGA仿真模型,对比了两种模型的差异,介绍了状态空间节点(SSN)算法、普约维奇方法及其提升仿真效率的原理,并就产生的不同仿真步长,对比分析了其对仿真结果的影响。定量研究了模型产生的接口延时,确定了接口延时与仿真器、仿真步长间的关系。仿真结果表明:对于开关频率较小的直驱风电机组,可通过CPU模型实现仿真,且引入SSN算法可进一步提升仿真效率;但CPU+FPGA模型的仿真步长更精细,接口延时更小,仿真结果更理想。Based on the RT-LAB simulation platform,CPU simulation model and FPGA simulation model of the direct-drive wind turbine generator are established and the differences between the models are compared.This paper introduces the principle of the State Space Node(SSN)algorithm and Pejovic method,and researches on the effects of different simulation step sizes on the simulation results.This paper quantitatively studies the interface delay generated by the model and gives the relationship between the interface delay and the simulator and simulation step size.The simulation result shows that wind turbine generator with low switching frequency can be achieved through the CPU model,and SSN algorithm can further improve the simulation efficiency.However,the simulation step size of the FPGA model is finer,the interface delay is smaller and results are more ideal.
