介绍了宁波电网的雷害现状,分析了雷击对宁波电网网架结构的严重影响,从全新的防雷视角,提出了基于现有网架结构的防雷思路,讨论了雷前雷后相结合的防雷调控应对策略,其中包括绘制雷害风险分布图、合理安排运行方式,关注同杆线路雷击故障,控制同杆线路比例等五项防雷策略,为宁波电网防雷工作的开展指明了新方向,也为传统的电网防雷提供了新思路。
介紹瞭寧波電網的雷害現狀,分析瞭雷擊對寧波電網網架結構的嚴重影響,從全新的防雷視角,提齣瞭基于現有網架結構的防雷思路,討論瞭雷前雷後相結閤的防雷調控應對策略,其中包括繪製雷害風險分佈圖、閤理安排運行方式,關註同桿線路雷擊故障,控製同桿線路比例等五項防雷策略,為寧波電網防雷工作的開展指明瞭新方嚮,也為傳統的電網防雷提供瞭新思路。

The present situation of lightning disturbance in Ningbo power grid is introduced and the serious effect of lightning on Ningbo power grid are analyzed. The paper, in a new lightning protection perspective, proposes a lightning protection idea based on current grid structure and discusses the dispatching strategy that combines protection before and after lightning strike, including five lightning protection strategies such as drawing of lightning distribution, reasonable arrangement of operation mode, concerning with lightning fail-ures of lines on the same tower and proportion control of lines on the same tower. This paper presents the new direction for Ningbo grid lightning protection work and also provides a new idea for the traditional grid light-ning protection.
