摘　　要：介绍了一种利用转子位置检测器测量发电机功角转速的装置。该装置由80C198单片机系统构成，实现了发电机功角和转速的测量及其模拟量和数字量的输出。利用一块128×64点阵的液晶显示功角的变化趋势，解决了发电机失步过程中功角难于观测的问题。动模实验表明，该装置对功角和转速的测量精度高，且功角稳定判据显示直观，为实施发电机稳定性的监视和控制奠定了基础。It is important to measure and use power anale and rotating rate when analyzing and improving generator stability. A kind of device is introduced in the paper for measuring power angle androtation rate of generator by using rotator position detector. The results of dynamic simulating test showthat the power angle for judging stability is displayed directly. It is proved that this device can be usedin real power system for monitoring and improving generator stability.
