The differential equations are based on basic electromagnetic laws in the stationary αβ 0 reference system for the induction generator. The variable coefficient differential equations were solved numerically with consideration of the magnetizing inductance influenced by the magnetizing currents. 利用三相自激异步发电机αβ0坐标系统模型,从发电机的基本电磁关系出发列写微分方程组,在考虑激磁电流对激磁电感影响的情况下对变系数微分方程用数值法求解。
