变电站微机监控实训
摘要
随着电力系统改造和自动化建设不断完善,电网企业大多已经实现了对远程变电站发电机组的的遥测、遥信、遥信、遥调,即“四遥”功能。变电站微机监控实训是电气自动化专业的实践环节。通过基于THLDK-2型电力系统监控实验台的微机监控实训可以加深我们对电力系统调度的理解与认识,初步掌握现代电力调度自动化系统的功能和基础操作。早期的电力系统调度手段,信息传递的速度慢,费时,费工,实时性差。电力系统采用远动技术后厂站端的远动装置实时地向调度中心的装置传送遥测和遥信的信息。远动装置中信息的生成,传输和处理速度非常快,适应了电力系统对调度工作的实时性要求,使电力系统的调度管理工作进入了自动化阶段

The puter monitoring training task
With the reform of electric power system and automation construction constantly improve, most power grid enterprises have realized the remote substation generator of telemetry, munication, munication, remote, namely "four control" function. puter monitoring training is electrical substation automation professional practice. Based on THLDK - 2 type puter 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 munication. 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
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、电力系统的远动技术
。即我们《配电自动化》课程中学****的四遥系统。其中遥信即遥远信号,,在调度所模拟盘上用灯光信号直接反映或用其它显示装置反映出来。遥测即遥远测量,
