中文摘要：

研究雷电和操作过电压的特征及防护是特高压系统建设及安全运行的关键问题之一。本项目在国际上首次提出综合考虑电力系统地上电网络及设备、地下接地系统的实际波过程的电磁暂态精确分析方法，用于分析电力系统的雷电及操作电磁暂态过程，使电磁暂态分析更接近实际波过程。系统研究包括绝缘子的非标准波冲击闪络特性及先导闪络判据模型，土壤的电-热击穿机理及接地系统时频特性模型，特高压导线的冲击电晕特性及伏-库特性模型，避雷器宽频特性模型等特高压系统关键元件的电磁暂态分析模型。提出基于电磁场和分形理论的雷电先导发展模型，从三维角度分析雷击特高压输电线路的行为特征。提出从防护绕击和降低操作过电压来深度限制特高压系统的过电压。研制满足特高压输变电工程深度限制过电压要求的低残压和大通流容量的压敏电阻，建立全新的低残压、大通流容量的压敏电阻体系，降低特高压设备的绝缘水平和制造瓶颈，可带来电力系统绝缘配合的第三次改变。
