摘　　要：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。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.
