同煤電網(wǎng)優(yōu)化設(shè)計

摘要

同煤電網(wǎng)由于設(shè)備陳舊，電網(wǎng)負荷分配不合理，不僅處于較差的運行狀態(tài)下，而且存在著安全隱患，對電網(wǎng)進行優(yōu)化已經(jīng)勢在必行。設(shè)計首先敘述了同煤電網(wǎng)的概況，在收集了數(shù)據(jù)的基礎(chǔ)上對同煤電網(wǎng)建立模型，并且將這些數(shù)據(jù)錄入至PSASP7.0中，制作出系統(tǒng)的單線圖，建立電網(wǎng)的基礎(chǔ)數(shù)據(jù)庫，并且模擬多種不同運行方式建立相應(yīng)潮流分析的方案進行潮流分布計算，得出合理結(jié)果后將其作為分析的數(shù)據(jù)基礎(chǔ)。通過對潮流計算結(jié)果分析后找出電網(wǎng)運行中的不合理和薄弱環(huán)節(jié)，最后根據(jù)各種方式計算電網(wǎng)各種運行方式下的損耗，重點分析問題嚴重的幾個變電所，提出解決方法，分析和總結(jié)出可行的調(diào)整方案并從經(jīng)濟角度進行對照，進行可行性分析，最后得出優(yōu)化后電網(wǎng)的運行狀況，總結(jié)被改善的環(huán)節(jié)。

Abstract

Datong Coal Mine Group Power Grid as a result of obsolete equipment, unreasonable load distribution, the operation not only in poor condition, but also there is a security risk ,the power grid must be optimized. First the design describe the overview of Datong coal industry group power grid ,build the model of Datong coal industry group power grid based on the collection of data, and entry these data to PSASP7.0, to establish the single system map, the basic database for grid, and simulate different methods of operation to establish the corresponding plans of power flow calculation and execute the calculation, the reasonable results will be the data basis of analysis. The results of trend analysis to identify unreasonable and weak parts in the operation of the power grid, and finally based on a variety of ways of calculating and the power grid loss under various operating mode, analysis of several substation problems, make propose solutions, analyze and summarize the possible adjustment programs and control from an economic point of view, to conduct a feasibility analysis, came to the conclusion that the optimized operation of the grid, summing up the part improved.
Keywords: Datong Coal Industry Group Grid; Power Flow Analysis; PSASP7.0;
