摘要
大量线路运行经验和雷电跳闸故障统计资料表明,雷电绕击是引起500k V及以上超特高压电压等级输电线路雷击跳闸的主要原因。本文较为详细地介绍了目前用于分析输电线路绕击耐雷性能的规程法、电气几何模型法、改进电气几何模型法、先导发展模型法、基于分形理论的先导发展模型法等各种绕击屏蔽模型和计算方法,并就今后的研究方向与侧重点提出了自己的见解。
A large number of transmission lines operation experience and statistics of lightning trip fault show that lightning shielding failure at 500kV and above voltage level extra-high voltage and ultra-high voltage transmission lines is the most common reason.This paper describes in detail about the strike shield models and calculation methods currently used to analyze the shielding property of transmission line. Such as regulation method, electro-geometric model, improved electro-geometric, LPM, based on the fractal-charaeterized LPM. And put forward their own views to focus research in the future.
