求翻译：(a)方向1通过计算待调整发电机对易失稳发电机群的影响因子，优先减少对系统暂态稳定性能影响较小的机组出力。调整结果中，A区减少的发电功率均来自对失稳机群暂稳性能影响较小的42号发电机，同时该机所在局部功率不平衡加剧，使得系统运行条件严重恶化，由此得到最保守的断面ATC。是什么意思？

(A) the direction of a generator to be adjusted by calculating the generator of the group's influence Yi instability factor, give priority to reducing the impact on the transient stability performance of a smaller unit to contribute. Adjusted results, A area to reduce the power output comes from tra
