西華煤礦供電系統(tǒng)可視化潮流仿真

摘要

針對(duì)煤礦供電系統(tǒng)要求安全、穩(wěn)定、經(jīng)濟(jì)運(yùn)行的實(shí)際問題，本設(shè)計(jì)利用美國(guó)伊利諾伊大學(xué)開發(fā)的電力系統(tǒng)仿真軟件包PowerWorld對(duì)電力系統(tǒng)進(jìn)行可視化潮流分析仿真設(shè)計(jì)。PowerWorld具有良好的用戶界面和交互性，仿真結(jié)果可以很直觀、形象的反映情況，使電網(wǎng)達(dá)到更安全、穩(wěn)定、經(jīng)濟(jì)的運(yùn)行的目的，也讓運(yùn)行調(diào)度人員對(duì)煤礦供電網(wǎng)運(yùn)行狀況有更清晰明確的認(rèn)識(shí)。
本設(shè)計(jì)還研究了潮流計(jì)算的基本數(shù)學(xué)模型和相關(guān)解法，分析比較各個(gè)數(shù)學(xué)模型的特點(diǎn)，并在此基礎(chǔ)上對(duì)牛頓－拉夫遜算法作出改進(jìn)，使其適合煤礦供電系統(tǒng)的潮流分析。
通過仿真模型的建立，分析供電網(wǎng)在正常運(yùn)行狀態(tài)、改投切狀態(tài)和故障狀態(tài)下的潮流分布，并對(duì)該煤礦供電網(wǎng)改造進(jìn)行預(yù)測(cè)分析。研究表明將可視化潮流分析軟件引入煤礦供電系統(tǒng)在生產(chǎn)實(shí)踐中具有重要的理論意義和實(shí)用價(jià)值。

Abstract

In allusion to the practical problems of mine power supply system safety,stability and economic operation, this text uses the power system simulation software package PowerWorld Simulator which developed by the US ILLinois University for the simulation design of power system visualization power flow analysis.  PowerWorld Simulator is a visible power system simulation package with excellent user interface intuitionistic and visual interactivity. The simulation result can reflect circs very intuitively and visually ，so that power grid can achieve a more secure, stable, and the purpose of economical operation, and then staff can specific realize the operating situation of coal mines power supply network.
This design also studies the basic mathematical model and related method of power flow analysis.It analyzes the characteristics of the various mathematical models and compares them.Based on that we improve the Newton - Raphson algorithm to make it fit power flow analysis of mine power system.
Through the  establishment of simulation model,it analyzes the load distribution in the states of normal operation of the electricity supply network, switching and fault, and then forecast the alterationcoal of power supply network. Visualization power flow analysis software is used in power supply system. Research shows that this plan has very important theory significance and practical value.
