大型发电机微机失步保护原理和方案
Out-of-step computer protection principle and method of large-scale generators
【摘要】 提出了一种用微机实现大型发电机失步保护的方案。这种方案根据单透镜的动作特性检测滑极次数,采用比幅比相的方法确定振荡中心位置,以发电机端测量阻抗的轨迹滑过单透镜的时间判断失步程度.
【Abstract】 An out-of-step computer protection method of large-scale generators is presented.The method employs the operation characteristic of einzel lens to detect the slip pole time.The comparison of the amplitude and phase is used to determine the vibratory center.The out-of-step degree is obtained by the time of impedance trace of generator terminal through the einzel lens.
