power angle characteristic造句

• The power angle characteristics are acquired and compared with the unsaturated curves . it is concluded that the stability limit of the power angle is less than 90 degree . reactive power regulating curves are calculated and compared with those curves when saturation effect is not considered , the result is that u type curves are deviated to the right
  通过对同步发电机各种运行曲线的计算，在已有文献的基础上更进一步分析了铁磁材料饱和以及磁场畸变对同步发电机运行特性和参数的影响；求出了空载特性曲线和零功率负载特性曲线，在不同的电枢电流下计算得到的波梯电抗不同；求出了功角特性曲线，与不计饱和时的功角特性曲线相比较，功角稳定极限小于90 ；求出无功调节曲线，与不计饱和时相比较， u型曲线向右偏移。
