摘要
所介绍的同步电动机励磁控制系统以8031单片机(STD)总线为核心。它主要由快速检测、移相触发控制、显示和主回路等单元组成,可以实现恒电流和恒功率因数控制等功能。该系统已运行半年以上,控制效果良好。
The excitation control system of synchronous motors, controlled by 8031 microcomputer (STD BUS), is presented in this paper. It consists of the synchronous measurement,phase-shift trigger control, display and power unit. It can realize constantcurrent and constant-power-factor control. After 6 months'service, it proves that good control result has been achieved.
