镇宁地区110kV架空线路雷击跳闸分析及防雷策略研究OA
Analysis and lightning protection strategy research on lightning-induced tripping of 110kV overhead transmission lines in Zhennning
为降低雷击对山地新能源场站电力送出的影响,提升输电线路雷害防护的有效性,本文以贵州镇宁地区某 100MW光伏电站为例,首先分析场站所在区域的地理气候条件和雷电时空分布规律,通过对雷击故障的暂态波过程及杆塔雷电压、雷电流成因的探讨,深入剖析输电线路杆塔雷击放电机理.事故现场勘察结果显示,输电线路雷击跳闸主要由杆塔接地电阻超标引发的反击雷过电压,以及超出耐雷水平的直击或绕击雷过电压导致.计及雷击跳闸的主要诱导因素,本文实施若干防雷措施,包括杆塔柔性接…查看全部>>
To mitigate the impact of lightning on power transmission from mountainous new energy stations and enhance the effectiveness of protection against lightning damage,this paper takes a 100MW photovoltaic station in Zhenning,Guizhou as a case study.It begins by analyzing the geographical and climatic conditions of the station's location,along with the spatial and temporal distribution of lightning.The study delves into the transient wave processes of lightning …查看全部>>
