输电线路雷击灾害风险层进式评估体系的构建

Dianci bileiqi, 2014
在深入研究各种输电线路雷击跳闸率计算方法并结合目前各网省公司线路管理现状的基础上,提出了输电线路雷击跳闸率预评估、再评估的层进式评估流程,并利用Visual Studio高级程序设计语言开发了一套输电线路雷击跳闸风险评估系统。该风险评估系统综合应用规程法、改进电气几何模型（EGM）、Google Earth地理信息软件和ATP/EMTP仿真计算等技术,评估范围覆盖了雷电绕击、反击等主要雷害型式,评估模型涉及线路地理特征信息、线路结构特征信息等影响要素,评估结果量化分析了各要素对雷击风险的影响 ...

考虑全雷击过程架空配电线路防雷性能计算分析

Dianci bileiqi
架空配电线路分布广泛且线路绝缘水平低，易发生直击雷和感应雷闪络故障，为了考虑配电线路受直击雷和感应雷过电压的综合影响，建立了配电线路耐雷性能计算模型。首先基于ATP-EMTP建立线路直击雷和感应雷过电压模型对线路耐雷水平进行仿真计算，然后通过电气几何模型并结合线路感应雷耐雷水平关于雷击点至线路距离的拟合关系式，对线路直击雷和感应雷闪络区域进行划分，进而计算得到线路直击雷和感应雷跳闸率，最后，计算分析了杆塔高度和大地电导率对配电线路耐雷水平以及雷击跳闸率的影响规律。计算结果表明 ...
