摘要
不饱和隐极同步发电机的特点是直轴同步电抗与交轴同步电抗相等,但在凸极同步发电机中,由于两者不相等,功角特性的表达式有所不同。结合凸极同步发电机的稳态条件,利用发电机的模型推导直轴同步电抗、交轴同步电抗、电枢电阻对其有功功率、电磁功率计算公式,并结合银盘电站发电机的参数使用MATLAB软件进行仿真分析,仿真结果与理论分析相吻合,得出影响凸级同步发电机输出功率的结论。
Unsaturated latent pole synchronous generator is characterized by equal vertical and quadratic synchronous reactance.However,in salient pole synchronous generators,the expression of the power angle characteristics is different because the two are not equal.Combined with the steady-state conditions of salient pole synchronous generator,the generator model was used to derive the calculation formulas of straight axis synchronous reactance,cross-axis synchronous reactance and armature resistance for its active power and electromagnetic power.Combined with the parameters of the generator of Yinpan Power Station,MATLAB software was used for simulation analysis.The simulation results are consistent with the theoretical analysis,and it is concluded that the output power of the salient pole synchronous generator is affected.
