【摘要】：在科技飛速發(fā)展的時(shí)代,微電子、自動(dòng)化的技術(shù)日趨成熟,我國經(jīng)濟(jì)的發(fā)展大背景越來越好,在這些基礎(chǔ)上,電力系統(tǒng)也蓬勃發(fā)展,變電站無人值守等企業(yè)模式的改變?yōu)殡娏ο到y(tǒng)的發(fā)展注入了活力。本文先從電能的特點(diǎn)及電力系統(tǒng)運(yùn)行的要求來對(duì)電力系統(tǒng)做了簡(jiǎn)要的介紹。隨后引出了我國低電壓?jiǎn)栴}的現(xiàn)狀和介紹了解決低電壓?jiǎn)栴}的實(shí)際意義。對(duì)自動(dòng)控制原理和自動(dòng)控制原理在電網(wǎng)的應(yīng)用也做了簡(jiǎn)明的敘述。在第二章中,首先進(jìn)行了一些公式的推導(dǎo)和定義的敘述,然后闡述了電力系統(tǒng)計(jì)算的原理。詳細(xì)列舉了電力線路、無功、設(shè)備原因等低電壓?jiǎn)栴}產(chǎn)生的原因,通過一個(gè)實(shí)例介紹了我國農(nóng)村低電壓?jiǎn)栴}的現(xiàn)狀。還介紹了電力系統(tǒng)中兩大類的調(diào)壓手段:利用主變分接頭調(diào)壓,和利用無功補(bǔ)償裝置調(diào)壓。并具體介紹了每大類調(diào)壓手段中,一般使用的調(diào)壓裝置。在第四章中,首先了介紹了220kV東鞍山變電站中SVC裝置的應(yīng)用情況。先從安裝位置的選擇、安裝容量的確定、控制方式的確定等幾方面出發(fā),分析了東鞍山變SVC安裝的實(shí)施方案。再從對(duì)電網(wǎng)的安全穩(wěn)定運(yùn)行和經(jīng)濟(jì)效益兩方面分析了SVC安裝后的實(shí)際效果。在介紹完SVC后,繼續(xù)介紹AVC(自動(dòng)電壓控制系統(tǒng))在鞍山電網(wǎng)中的應(yīng)用。鞍山供電公司在電力調(diào)度控制中心引入了自動(dòng)電壓控制系統(tǒng)(以下簡(jiǎn)稱AVC),對(duì)鞍山電網(wǎng)所轄變電站的無功補(bǔ)償設(shè)備進(jìn)行集中監(jiān)視、管理和控制,從而實(shí)現(xiàn)對(duì)全網(wǎng)無功電壓優(yōu)化集中自動(dòng)控制。分別從功能、控制原理、設(shè)計(jì)實(shí)現(xiàn)、操作界面等方面全面的介紹了AVC裝置。
[Abstract]:In the era of rapid development of science and technology, the technology of microelectronics and automation is maturing day by day, and the background of the economic development of our country is getting better and better. On the basis of these, the power system is also booming. The change of enterprise mode, such as unattended substation, has injected vitality into the development of power system. In this paper, the characteristics of electric energy and the requirements of power system operation are introduced briefly. Then the present situation of low voltage problem in China and the practical significance of solving low voltage problem are introduced. The application of automatic control principle and automatic control principle in power system is also described concisely. In the second chapter, the derivation and definition of some formulas are given, and then the principle of power system calculation is expounded. The causes of low voltage problems such as power lines, reactive power and equipment are listed in detail, and the present situation of low voltage problems in rural areas in China is introduced by an example. This paper also introduces two kinds of voltage regulation methods in power system: voltage regulation by main transformer connector and voltage regulation by reactive power compensation device. The general voltage regulating device used in each kind of voltage regulation means is introduced in detail. In the fourth chapter, the application of SVC in 220 kV Donganshan Substation is introduced. Starting from the selection of installation position, the determination of installation capacity and the determination of control mode, the implementation scheme of Donganshan variable SVC installation is analyzed. The practical effect of SVC installation is analyzed from two aspects: safe and stable operation and economic benefit. After introducing SVC, the application of AVC (automatic voltage control system) in Anshan power network is introduced. Anshan Power supply Company introduced the automatic Voltage Control system (AVCU) in the power dispatching control center to monitor, manage and control the reactive power compensation equipment in the substations under the jurisdiction of Anshan Power Grid. In order to realize the whole network reactive power and voltage optimization centralized automatic control. The AVC device is introduced from the aspects of function, control principle, design and implementation, operation interface and so on.
