基于VisSim的SCIG风力发电机组动态模型建模与研究

给出了基于鼠笼型感应发电机(SClG)的风力发电机组的五阶与三阶动态模型,其中五阶模型包括定子、转子模型及简化的传动系统模型;忽略定子暂态过程后,得到包括转子模型及简化的传动系统模型的三阶模型.在VisSim仿真软件上实现了上述两种模型的建模,并针对各自的响应特征进行了仿真比较.仿真结果验证基于VisSim的SCIG风力发电机组建模的正确性,同时也为风力发电机组的仿真研究提供了一个新的途径.

Modeling and Simulation of Squirrel-Cage Induction Generator Wind Turbine Using VisSim

In this paper,the 5th and 3rd order models of SCIG wind turbine were discussed respectively. The 5th order model included the drive train, the stator and the rotor models. The 3rd order model comprised the rotor model and the drive train with the ststor transients being neglected. These two types of SCIG wind turbine were modeled utilizing VisSim, and their responses were compared. The simulation resulta demonstrate that the model of SCIG wind turbine using VisSim is cor-rect,and the VisSim provides a new method for the simulation of SCIG wind turbine.
