摘要
就一种用ＭＣＳ－５１系列的８７Ｃ５１单片机控制同步机励磁系统的关键技术进行了研究，并就同步电动机在异步起动过程中转差率的检测和显示、起动后当转子转速达到亚同步时的准确投励、整流触发脉冲的形成和分配等方面作了较为详细的分析．
A control system for the excitation system of a synchronous machine with type 87C51 single chip computer of MCS 51 series is presented. A block diagram each of the system hardware and software is given, and the operating principle as well as the control ideas are described. The measurement and display of the slip during the start of a synchronous motor, the accurate switch in instant of the excitation when the motor reaches subsynchronous speed and the forming and distribution of the SCR triggering pulse are analyzed.
