摘要

云南电网雷电定位系统已经平稳的运行了多年

为充分应用雷电定位系统积累的数据

为雷电防护服务

开展了云南电网雷害风险分布图的绘制与应用的研究。首先对云南雷电定位系统数据进行重算

建立样本统计数据库

进而得到云南的落雷密度分布图和雷电流幅值概率曲线

然后结合云南电网雷击故障历史数据

采用规程法得到反击危险雷电流

利用考虑击距系数和地面倾角的电气几何模型

得到绕击危险雷电流

最后根据危险雷电流区间和云南落雷情况

绘制出云南电网雷害风险分布图

得到了云南雷害风险分布情况。在此基础上

给出了云南高海拔地区雷害风险分布的应用原则

可为云南电网防雷设计和反措提供技术支撑。

Abstract

Lightning location system in Yunnan power grid has smoothly operated for years

in order to full use of lightning data

and for lightning protection services

the drawing and application of lightning hazard map of Yunnan power grid are carried out.First of all

sample statistic database is established through to the yunnan lightning location system data processing and then the lighting density distribution of Yunnan and lightning current probability amplitude curve are gotten.Referring to the historic lightning faults in Yunnan power grid

the lightning strike dangerous current by the procedure law of china is calculated.By use of electrical geometric model with consideration of ground elevation

the striking distance to get the shielding failure dangerous lightning curren is also gotten.At last

based on the lighting dangerous currernt and linghing strike in Yunnan

the lightning hazard maps in Yunnan power grid has been drawn and the application principle of the lightning hazard map is given.It can provide technical support of lightning protection design and countermeasures for Yunnan power grid.
