基于Matlab的转桨式恒速风电机组三相短路故障分析

Analysis of Three-phase Short-circuit Fault in Wind Turbine With Fixed Speed and Rotatable Paddle Based on Matlab

针对定速转桨风电机组,基于Matlab建立发电机的数学模型,阐述对于并网运行过程中发生的三相短路故障仿真和分析,在基本风及渐风输入模式下产生的特征参数变化及对系统稳定性的影响。

This paper takes the fixed-speed wind generator as the research object. It establishes a mathematical model of the generator based on Matlab and simulates and analyzes the three-phase short-circuit fault occurring in the process of grid-connected operation so as to further explore the change of characteristic parameters and its influence on system stability under basic wind and gradual wind input mode.
