內容簡介
過電壓分析在輸變電工程和設備設計最佳化、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，而過電壓暫態數值計算分析使得重複性的數值試驗成為可能，大大增進了對過電壓暫態發展過程的理解，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電廠等電力系統運行單位比較薄弱的現狀，作者採用通用過電壓分析軟體，在理論分析和合理建模基礎上，對近年來廣東電網乃至南方電網的近三十個過電壓相關的故障仿真進行計算分析，為電網故障分析、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、電磁振盪引起的內部過電壓分析，以及絕緣配合的最佳化等，也引入了連續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線上路諧振條件下傳變特性、隔離開關操作引發電磁暫態過程、500kV線路高壓並聯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TV低頻振盪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場故障案例分析作為特色，理論與實際結合緊密，圖文並茂，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實際的科技圖書。
