途径采动影响区特高压直流线路设计对策研究

Study on the Designing Measures of UHVDC Line in Mining-affected Areas

特高压直流输电具有线路造价低、稳定性好、输送容量大等优点,是我国骨干电网的重要组成部分,但由于其输送距离长,途经各类不良地质区域多,需重点分析各类不良地质对线路的影响。分析了采动影响区对特高压直流线路的影响,结合工程建设经验,从勘察和设计方面提供了一些解决措施和处理方案,以期对后续设计提供参考。

As an important part of China's major power grid,ultra high voltage direct current(UHVDC)power transmission line.has many advantages,such as low cost,good stability and large transmission capacity.However,UHVDC transmission line has to face many undesirable geological areas because of its long transportation distance.So it is necessary to pay special attention to the analysis of the influence of various undesirable geological areas on the transmission line.Firstly,the impact of mining-affected areas on UHVDC transmission lines is analyzed.Secondly,combined with some previous engineering construction experiences,some solutions are provided from both survey and design aspects in order to provide some references for subsequent design.
