变电站微机监控实训

摘要

这次实训是基于THLDK-2型电力系统监控实验台在我们电气工程及其自动化专业展开的学习，通过实验，我们可以组网，通过控制界面调节有功和无功功率以及向总控制台发送控制申请来获得对发电厂的控制，通过组态界面来查看各项参数变化情况，查询事故报告，通过进一步认识我们在THLDK-2型电力系统监控实验台上完成遥控、遥测、遥信、遥调四遥实验，另一个实训平台是基于TQXBZ-II-C多功能继电保护及变电站综合自动化实验培训系统，通过本实验平台，我们完成了三段式电流保护实验；10kV 、35kV微机线路保护实验；变压器保护实验。了解实验原理的基础上，在TQXBZ-II-C 实验系统上验证结果，所谓的变电站，即是改变电压的场所。为了把发电厂发出来的电能输送到较远的地方，必须把电压升高，变为高压电，到用户附近再按需要把电压降低，这种升降电压的工作靠变电站来完成。变电站是电力系统的一个重要组成部分，它的安全可靠运行是电网安全经济运行的根本保证。当前变电站正以分项自动化向着综合自动化方向发展，综合自动化的近期目标是把变电站的保护、测量、监控、远动等融为一体，取得数据共享，资源共享，大幅度提高自动化的功效。

实训虽没有现场设备齐全，但对于这次实习，我从中更加理会了理论的内容。

Substation computer monitoring practice

Abstract

This practice is based on THLDK - 2 type electric power system monitoring test bench in our electrical engineering and automation of the study, through the experiment, we can network, through adjust the active and reactive power control interface and send total console control application to gain control of the power plant, through the configuration interface to view the various parameters change, the query accident report, by further know us in THLDK-2power system monitoring laboratory bench complete remote control, remote sensing, remote communication, remote regulating four remote experiment, another training platform is based on TQXBZ - II - C multi-function relay protection and substation integrated automation experimental training system, through this experimental platform, we completed the three-step current protection experiment; 10 kv, 35 kv microcomputer line protection; Transformer protection experiment. Understand the principle on the basis of the experiment in TQXBZ - II - C experiment system on the test results,

So-called substation, is to change the voltage. In order to put the power of electricity to the distant place, must take the voltage, a high voltage, near to the users according to the need to reduce the voltage again, this kind of work on lifting voltage transformer substation. Substation is an important part of power system, it's safe and reliable operation is the fundamental assurance for the safe and economic operation of power grid. Current towards integrated automation substation is itemized automation and integrated automation of short-term goal is to put the substation protection, measurement, monitoring, remote, etc, data sharing, resource sharing, greatly improve the effect of automation.

Training is not complete field devices, but for this internship, I have more to the content of the theory

Key words: Relay protection, configuration interface, current protection，distance protection, Four control system
