    • Method for identifying pole slip of an electrical generator (2), in particular synchronous generator, which is electrically connected to a power supply system (1), wherein a rotor (3) of the generator (2) is mechanically connected to a motor shaft (4) of an internal combustion engine (5), in particular of a gas engine, wherein the internal combustion engine (5) is operated at a substantially constant mechanical rotation frequency (n) in a stationary operating mode, wherein the mechanical rotation frequency (n) of the motor shaft (4) and an electrical rotation frequency (f) of the power supply system (1) are detected or ascertained, wherein a signal (11) is output in the event of a deviation (6) in the mechanical rotation frequency (n) from the electrical rotation frequency (f) of greater than a prespecifiable threshold value (7), wherein the signal (11) is considered to be a detected pole slip.
    • 用于识别与电源系统(1)电连接的发电机(2)的特别是同步发电机的极滑的方法,其中所述发电机(2)的转子(3)机械地连接到电动机轴 (5),特别是燃气发动机的内燃机(5),其中内燃机(5)在静止运行模式下以基本恒定的机械旋转频率(n)运行,其中机械旋转频率 检测或确定电动机轴(4)的电动机(n)和电力供应系统(1)的电气旋转频率(f),其中在发生偏差(6)的情况下输出信号(11) 来自电旋转频率(f)的大于预定阈值(7)的机械旋转频率(n),其中信号(11)被认为是检测到的极滑。
