2、態(tài)參量包括電網(wǎng)各母線節(jié)點的電壓幅值和相角，以及各 支路的功率分布、網(wǎng)絡(luò)的功率損耗等。傳統(tǒng)的潮流計算程序缺乏圖形用戶界面，結(jié)果顯 示不直觀，難于與其他分析功能集成，網(wǎng)絡(luò)原始數(shù)據(jù)輸入工作量大且易于出錯。結(jié)合電 力系統(tǒng)的特點，對于復(fù)雜電力系統(tǒng)，根據(jù)定條件，應(yīng)用牛頓 -拉夫遜法進行計算，在手工 計算中，由于涉及大量變量、微分方程、矩陣計算，求解很繁瑣，計算不同系統(tǒng)時需要 重新計算。運用MATLAB軟件進行仿真潮流計算，圖形界面直觀，運行穩(wěn)定，計算準確， 提高了計算速度，各個類的有效封裝又使程序具有很好的模塊性可維護性和可重用性。關(guān)鍵詞：電力系統(tǒng)潮流分析；牛頓-拉夫遜法潮流分析；Matlab仿真;4兩機
