求翻译：我提前自学了电机拖动，自动控制系统与电力系统分析等课程，并掌握了发电机励磁系统模型的建立方法，系统稳定性的判别和分析方法，是什么意思？

I drag the motor learning in advance, automatic control system and power system analysis courses, and master the excitation system model method, system stability, and discriminant analysis methods,

I advance the electric drag self-learning, automatic control systems and electrical systems analysis courses such as generators, and controlled the excitation system modeling methods, system stability and analytical methods, 6,772

I have studied independently ahead of time the electrical machinery dragging, curricula and so on automatic control system and electrical power system analysis, and have grasped the generator excitation system model establishment method, the system stable distinction and the analysis method,

I learned early motor drive, automatic control system and electric power systems analysis courses, and mastered the establishment method of generator excitation system models, identification and analysis of system stability,
