鲁固特高压直流黄河跨越点选择

Selection of Crossing Point for Yellow River Long Span Crossing of Lugu UHVDC

鲁固特高压直流是外电入鲁继±660 kV银东线、±800 kV昭沂直流后的第3条直流输电通道,在山东境内跨越黄河,主跨越档距超过1 300 m,最高铁塔高度接近140 m,设计阶段需按照大跨越设计。结合工程实际,重点介绍了黄河大跨越的跨越点选择原则、多方案技术和经济比较、设计重点要求等内容,可为后续工程的黄河大跨越提供设计参考。

Lugu UHVDC,as the third DC transmission channel after ±660 kV Yindong Line and±800 kV Zhaoyi UHVDC transmitting external power to Shandong has part of its path crossing the Yellow River. The main span is over 1300 meters,and the maximum tower height is approximately 140 meters. The project was designed complying large-crossing standard. Based on the engineering practice,the principle for selecting crossing points was introduced. Technical and economic comparison of various schemes is carried out. This work will provide design guidance for the following project of large-span crossing on the Yellow River.
