- 摘要:
- 随着经济的发展,城市化进程的加速,我国地磁观测受到的干扰日趋严重,近年来兴建的高压直流输电工程对地磁观测的影响尤其突出。笔者调研我国目前及将来高压直流输电工程的分布和影响范围,初步分析了高压直流输电对地磁观测的干扰原理和典型的干扰曲线形态,为地磁数据预处理和利用提供一定的参考。
As economic development and the accelerated urbanization, the disturbance has become increasingly serious in geomagnetic observation, and the impact of HVDC is particularly conspicuous. In this paper, we have studied the distribution of the current and future HVDC projects and the affected area. At the same time we primarily analyzed about the principle and the typical tracing pattern of HVDC interference.
