內(nèi)容簡介

　　過電壓分析在輸變電工程和設(shè)備設(shè)計(jì)優(yōu)化、絕緣配合校驗(yàn)，以及故障分析和制定反措等方面起到越來越重要的作用，而過電壓暫態(tài)數(shù)值計(jì)算分析使得重復(fù)性的數(shù)值試驗(yàn)成為可能，大大增進(jìn)了對過電壓暫態(tài)發(fā)展過程的理解，在過電壓分析中扮演越來越重要的角色。針對該基礎(chǔ)性工作在供電部門和發(fā)電廠等電力系統(tǒng)運(yùn)行單位比較薄弱的現(xiàn)狀，作者采用通用過電壓分析軟件，在理論分析和合理建模基礎(chǔ)上，對近年來廣東電網(wǎng)乃至南方電網(wǎng)的近三十個(gè)過電壓相關(guān)的故障仿真進(jìn)行計(jì)算分析，為電網(wǎng)故障分析、反事故技術(shù)措施制定和絕緣配合校核等提供了有力的技術(shù)支持。本書是廣東電網(wǎng)有限責(zé)任公司電力科學(xué)研究院近年來開展過電壓計(jì)算分析工作經(jīng)驗(yàn)的總結(jié)，共分為9章，結(jié)合有代表性的案例分析，主要涉及雷電侵入波引起的外部過電壓分析、電磁振蕩引起的內(nèi)部過電壓分析，以及絕緣配合的優(yōu)化等，也引入了連續(xù)雷擊嚴(yán)苛工況下線路側(cè)避雷器保護(hù)距離和能量吸收的校核、CVT在線路諧振條件下傳變特性、隔離開關(guān)操作引發(fā)電磁暫態(tài)過程、500kV線路高壓并聯(lián)電抗器退運(yùn)條件計(jì)算評(píng)價(jià)、架空輸電線路感應(yīng)電壓和配電網(wǎng)TV低頻振蕩等近年來過電壓與絕緣配合技術(shù)領(lǐng)域新內(nèi)容。本書以有代表性的現(xiàn)場故障案例分析作為特色，理論與實(shí)際結(jié)合緊密，圖文并茂，具有較強(qiáng)的實(shí)操性，是國內(nèi)介紹過電壓計(jì)算分析方面較為貼近生產(chǎn)實(shí)際的科技圖書。
