1、哈爾濱理工大學(xué)學(xué)士學(xué)位論文慶安地區(qū)電網(wǎng)潮流計(jì)算及最優(yōu)運(yùn)行方式的研究摘要眾所周知,電網(wǎng)調(diào)度是電力安全生產(chǎn)管理的核心,對(duì)電網(wǎng)運(yùn)行實(shí)行"統(tǒng)一調(diào)度、分級(jí)管理"的原則。地區(qū)電網(wǎng)潮流分析與優(yōu)化的目的和意義潮流計(jì)算和分析是電容,在保證電網(wǎng)安全、穩(wěn)定運(yùn)行的基礎(chǔ)上,提高電網(wǎng)調(diào)度管理水平,是調(diào)度部門必須認(rèn)真研究的課題??茖W(xué)的調(diào)度可以提高公司的經(jīng)濟(jì)效益,最大限度地保證對(duì)用戶多供電、供好電,以強(qiáng)大的電網(wǎng)和有效的管理提高為客戶服務(wù)的能力。電壓水平是電能質(zhì)量的一個(gè)重要指標(biāo),做好電力系統(tǒng)的無(wú)功優(yōu)化和控制是提高電壓質(zhì)量和穩(wěn)定的重要措施之一。本次設(shè)計(jì)主導(dǎo)思想為:首先,利用MATLAB編程,采
2、用PQ分解法,針對(duì)慶安地區(qū)5點(diǎn)和10點(diǎn)的負(fù)荷進(jìn)行仿真,研究整個(gè)慶安電網(wǎng)的潮流分布,從理論上分析電網(wǎng)運(yùn)行的安全性、經(jīng)濟(jì)性和可靠性。其次,分析電網(wǎng)運(yùn)行中的薄弱環(huán)節(jié)并加以解決,對(duì)電網(wǎng)的可接電容補(bǔ)償節(jié)點(diǎn)進(jìn)行優(yōu)化,改善電網(wǎng)無(wú)功分布,提高電網(wǎng)經(jīng)濟(jì)運(yùn)行水平。再次,分析不同無(wú)功補(bǔ)償、不同運(yùn)行方式下的電網(wǎng)運(yùn)行情況,提高運(yùn)行方式調(diào)整的靈活性。最終,通過(guò)潮流計(jì)算和分析,為科學(xué)、合理、超前規(guī)劃電網(wǎng)提供決策依據(jù).,以達(dá)到電網(wǎng)的有功網(wǎng)損最??;電壓質(zhì)量最好,合格率最高,系統(tǒng)的無(wú)功補(bǔ)償容量最小,總運(yùn)行費(fèi)用最低。,提出了具有可實(shí)踐操作意義的措施。關(guān)鍵詞: 潮流計(jì)算;無(wú)功補(bǔ)償;最優(yōu)運(yùn)行-II-
