Microcomputer monitoring training is electrical substation automation professional practice. Based on THLDK - 2 type microcomputer monitoring of electric power system monitoring practice can deepen our understanding of the power system dispatching and understanding, preliminary mastered the basic functions of modern electric power dispatching automation system and operation. Early means of power system dispatching, information transmission speed is slow, time-consuming, work, real-time performance. Station after power system adopts the operation technique of the telecontrol device in real time to the dispatch center device information transmit telemetry and remote communication. The production of information in the remote device, transmission and processing speed is very fast, to adapt to the real-time demand of power system for scheduling work, make the dispatching management of electric power system has entered the phase of automation 第一章 电力系统监控1.1电力系统监控的由来电力系统监控以计算机、通讯设备、测控单元为基本工具，为变配电系统的实时数据采集、开关状态检测及远程控制提供了基础平台，它可以和检测、控制设备构成任意复杂的监控系统，在变配电监控中发挥了核心作用，可以帮助企业消除孤岛、降低运作成本，提高生产效率，加快变配电过程中异常的反应速度。1.1.1电力系统监控组成1、电力系统的远动技术电力系统的远动技术是经通道对被调度对象实行遥信.遥测.遥控.遥调的一种技术。即我们《配电自动化》课程中学习的四遥系统。其中遥信即遥远信号，其作用是将被监视的发电厂.变电站的主要设备及线路的断路器位置信号及其它用途的信号传送给调度所，在调度所模拟盘上用灯光信号直接反映或用其它
