摘要
在电力系统中,突然短路是一种严重的故障也是一种重要的瞬变现象。dq0坐标变换是一种最常用的有效的对水轮发电机瞬态过程做出准确分析的方法。这种方法具有结果准确、适用面广等特点。运用派克方程分析了定子电流的表达式,并利用MATLAB针对具体的水轮发电机的短路电流进行了仿真研究。
In power system, sudden-short is a serious breakdown and an important transient phenomenon, dq0 coordinate variations is a kind of the most general and very effective tool in analyzing the transient process of hydro-generator. It has the characteristics of accuracy and wider in range of applicability. In this paper, stator current is analyzed by Park Equation and sudden-short current of hydro-generator is simulated and analyzed by MATLAB.
