摘要
本文提出了一种基于可编程计算机控制器(PCC)的励磁实现方案。PCC的硬件继承了PLC的高可靠性,同时具备实现高速任务的能力。本文介绍了使用PCC的IP161模块实现交流采样、周期测量和形成移相脉冲的方法。动模实验验证了这种方案的可行性。
A scheme of excitation controller based on programmable computer controller （PCC） is presented. PCC is as reliable as programmable logic controller （PLC）. It＇s also able to complete some high speed tasks that PLC can＇t do. The ways to realize frequency measurement and Fourier sample with PCC are discussed. And the scheme of emitting control pulses to SCR bridges is introduced as well. Dynamic simulations on a physical model verify the scheme.
