布容—松山极性倒转事件的海陆地质记录及其不同步性探讨

, 2012
布容—松山(B/M)极性倒转事件是第四纪发生的最近一次地磁极性倒转,研究地磁极性倒转的特征不仅对理解地磁场演化规律具有重要意义,同时极性倒转通常具有全球等时性,因此常被视为地层划分和全球气候对比的关键时间标记物。然而古地磁研究表明,布容—松山事件在海洋与中国黄土沉积物中的记录存在着"错位"现象,使得基于磁性地层年代框架下的中国黄土—古土壤序列与全球气候记录之间的对比存在不确定性。基于这一问题,重点回顾了B ...

特高压直流接地极近区新能源入网运行方式对直流偏磁电流分布的影响研究

Gaoya dianqi
湖北境内有多条直流外送通道，运行以来多次发生单极闭锁，直流偏磁的风险评估和防御治理问题突出。武汉特高压换流站的接地极位于随州广水岗上湾，接地极近区新能源站分布密集、数量众多，新能源接入电网方式对随州地区直流偏磁分布影响显著。本文开展随州地区新能源站多种接入电网方式下直流偏磁分析研究，获得了不同运行工况下新能源站和枢纽变电站直流偏磁电流分布规律，首次提出从优化电网调度运行方式的角度来治理直流偏磁问题。结果表明，金山风电场、吉阳光伏场对随州永阳和景星供区直流偏磁分布的影响比其他新能源站显著。根据分析 ...
