內容簡介

　　過電壓分析在輸變電工程和設備設計優(yōu)化、絕緣配合校驗，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)值計算分析使得重復性的數(shù)值試驗成為可能，大大增進了對過電壓暫態(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。針對該基礎性工作在供電部門和發(fā)電廠等電力系統(tǒng)運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?；A上，對近年來廣東電網(wǎng)乃至南方電網(wǎng)的近三十個過電壓相關的故障仿真進行計算分析，為電網(wǎng)故障分析、反事故技術措施制定和絕緣配合校核等提供了有力的技術支持。本書是廣東電網(wǎng)有限責任公司電力科學研究院近年來開展過電壓計算分析工作經(jīng)驗的總結，共分為9章，結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)雷擊嚴苛工況下線路側避雷器保護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)電抗器退運條件計算評價、架空輸電線路感應電壓和配電網(wǎng)TV低頻振蕩等近年來過電壓與絕緣配合技術領域新內容。本書以有代表性的現(xiàn)場故障案例分析作為特色，理論與實際結合緊密，圖文并茂，具有較強的實操性，是國內介紹過電壓計算分析方面較為貼近生產(chǎn)實際的科技圖書。
