1、基于MALAB的牛頓拉夫遜法潮流計(jì)算基于MALAB的牛頓拉夫遜法潮流計(jì)算摘要本文,首先簡單介紹了基于在MALAB中行潮流計(jì)算的原理、意義,然后用具體的實(shí)例,簡單介紹了如何利用MALAB去進(jìn)行電力系統(tǒng)中的潮流計(jì)算。眾所周知,電力系統(tǒng)潮流計(jì)算是研究電力系統(tǒng)穩(wěn)態(tài)運(yùn)行情況的一種計(jì)算,它根據(jù)給定的運(yùn)行條件及系統(tǒng)接線情況確定整個(gè)電力系統(tǒng)各部分的運(yùn)行狀態(tài):各線的電壓、各元件中流過的功率、系統(tǒng)的功率損耗等等。在電力系統(tǒng)規(guī)劃的設(shè)計(jì)和現(xiàn)有電力系統(tǒng)運(yùn)行方式的研究中,都需要利用潮流計(jì)算來定量地分析比較供電方案或運(yùn)行方式的合理性、可靠性和經(jīng)濟(jì)性。此外,在進(jìn)行電力系統(tǒng)靜
2、態(tài)及暫態(tài)穩(wěn)定計(jì)算時(shí),要利用潮流計(jì)算的結(jié)果作為其計(jì)算的基礎(chǔ);一些故障分析以及優(yōu)化計(jì)算也需要有相應(yīng)的潮流計(jì)算作配合;潮流計(jì)算往往成為上述計(jì)算程序的一個(gè)重要組成部分。以上這些,主要是在系統(tǒng)規(guī)劃設(shè)計(jì)及運(yùn)行方式安排中的應(yīng)用,屬于離線計(jì)算范疇。牛頓-拉夫遜法在電力系統(tǒng)潮流計(jì)算的常用算法之一,它收斂性好,迭代次數(shù)少。本文介紹了電力系統(tǒng)潮流計(jì)算機(jī)輔助分析的基本知識(shí)及潮流計(jì)算牛頓-拉夫遜法,最后介紹了利用MTALAB程序運(yùn)行的結(jié)果。關(guān)鍵詞:電力系統(tǒng)潮流計(jì)算,牛頓-拉夫遜法,MATLABIV基于MALAB的牛頓拉夫遜法潮流計(jì)算IVABSTRACTThisarti
