摘要
近年来,直流输电工程以其自身线路损耗小、造价低等优点越来越受到人们的关注。针对换流站各部分不同的防雷标准,结合±660 kV宁东直流输电工程中青岛换流站的防雷保护计算,总结归纳了滚球法的定义和各种情况下保护范围的计算公式,尤其通过复杂的公式推导过程,得出三角形避雷线保护范围的计算公式,完善了避雷线在换流站防雷保护中的应用。
In recent years, DC Transmission Project is payed increasing attention because of its advantage, such as less loss, low cost, and so on. Different parts in converter station have different Lightning protection standards.The paper calculated lightning protection area of Qingdao converter station in Ningdong DC Transmission Project, and Summarized the definition of rolling ball method and formulas of protection area in all cases. Also, formulas of triangle lightning conductor protection area are inferred. The method consummates the lightning conductor protection application in converter station.
