摘要
分析2004年广东电网线路故障和空间天气之间的对应关系,得知53%的电力系统故障与空间天气扰动状态存在对应关系。在所有考虑的空间天气扰动状态中,地磁状态占据主导地位(36%),而太阳活动和同步轨道电磁环境对地面电力系统的直接影响较小(17%)。
This paper analyzes the fault lines in Guangdong power grid in 2004 and their relationship with space weather.And results show that more than half of the power system faults(53%) are in correlation with the space weather disturbances,among which,the geomagnetic activities are in dominant position(36%),while the solar activities and sun-synchronous orbit electromagnetic environment have less effect on ground power systems(17%).Therefore more attention should be drawn to the space weather forecasting of geomagnetic activities to alleviate the power failure and the loss caused by it.
