摘要
介绍了基于S7-200型可编程控制器控制同步发电机励磁监控系统的方法。在系统中,应用自由口通信方式实现了Modbus通信协议,采用第三方软件Delphi编制励磁监控软件,采用面向对象的方法实现了多线程技术,初步实现了对同步发电机励磁的实时监控。
The method of supervisory control system for synchronous generator＇s excitation based on Model S7-200 program- mable logic controller was introduced. In this system, to apply free-port communication method realizes Modbus communication protocol, by adopting the third-party software of Delphi to program supervisory control software, and using objective-oriented method to carry out multi-threading technique, achieve preliminarily the function of real-time supervisory control on synchronous generator＇s excitation.
