1、華北電力大學（保定）碩士學位論文烏海電網(wǎng)現(xiàn)狀及規(guī)劃研究姓名：訾偉申請學位級別：碩士專業(yè)：電氣工程指導教師：李琳劉俠20081230華北電力大學工程碩士學位論文摘要摘要本文主要是通過對烏海電網(wǎng)的現(xiàn)狀，及存在問題進行分析，找出電網(wǎng)存在的薄弱環(huán)節(jié)，合理規(guī)劃，加強電網(wǎng)建設(shè)，確保烏海電網(wǎng)的安全，可靠的運行，提高電網(wǎng)的輸送能力。首先通過電力負荷的分類預測，進行電力電量平衡，合理的選擇變電站的站址和送電線路的路徑，作出網(wǎng)絡方案的設(shè)計，確定電壓等級，輸

2、變電設(shè)備的數(shù)學模型，及網(wǎng)絡參數(shù)，其次進行必要的電氣計算(潮流、穩(wěn)定、短路)，最后根據(jù)計算結(jié)果和經(jīng)濟比較的方法，確定最優(yōu)的電網(wǎng)規(guī)劃方案。關(guān)鍵詞：電網(wǎng)現(xiàn)狀，負荷預測，電力平衡，電網(wǎng)規(guī)劃ABSTRACTThisarticlemainlyisthroughtotheWuhaielectricalnetworkpresentsituation，andtheexistencequestioncarriesontheanalysis，discover
