STD总线的智能低频减负荷系统的研究

AN STD BUS BASED INTELLIGENT SYSTEM FOR LOAD SHEDDING ACCORDING TO FREQUENCY

本文介绍了一种采用ＳＴＤ工业控制总线构成的智能低频减负荷系统，介绍了该系统的工作原理、系统结构及软件设计。该系统能根据系统频率下降速率自动提高动作频率定值，缩短动作延时，快速切除所控制的负荷，有利于系统安全稳定运行。

n STD bus based intelligent load shedding system according to frequency is described in this paper.The principle, architecture and software design of the system is presented. In order to reduce the time-delay of load shedding, in this system the operating frequency constant can be automatically adjusted according to the decreasing rate of frequency, and it is beneficial to the stable and secure operation of power system.
