内容简介
过电压分析在输变电工程和设备设计优化、绝缘配合校验,以及故障分析和制定反措等方面起到越来越重要的作用,而过电压暂态数值计算分析使得重复性的数值试验成为可能,大大增进了对过电压暂态发展过程的理解,在过电压分析中扮演越来越重要的角色。针对该基础性工作在供电部门和发电厂等电力系统运行单位比较薄弱的现状,作者采用通用过电压分析软件,在理论分析和合理建模基础上,对近年来广东电网乃至南方电网的近三十个过电压相关的故障仿真进行计算分析,为电网故障分析、反事故技术措施制定和绝缘配合校核等提供了有力的技术支持。本书是广东电网有限责任公司电力科学研究院近年来开展过电压计算分析工作经验的总结,共分为9章,结合有代表性的案例分析,主要涉及雷电侵入波引起的外部过电压分析、电磁振荡引起的内部过电压分析,以及绝缘配合的优化等,也引入了连续雷击严苛工况下线路侧避雷器保护距离和能量吸收的校核、CVT在线路谐振条件下传变特性、隔离开关操作引发电磁暂态过程、500kV线路高压并联电抗器退运条件计算评价、架空输电线路感应电压和配电网TV低频振荡等近年来过电压与绝缘配合技术领域新内容。本书以有代表性的现场故障案例分析作为特色,理论与实际结合紧密,图文并茂,具有较强的实操性,是国内介绍过电压计算分析方面较为贴近生产实际的科技图书。
