摘要:
为进一步提高山东地磁台网受高压直流输电干扰的预处理质量,通过中国地震前兆数据处理系统中相对差值检测和预处理检测功能,对山东地磁台网多年来受宁东高压直流输电干扰预处理情况进行了总结分析。结果表明,经过数据预处理,宁东高压直流输电干扰基本被去除,但仍然存在高压直流输电干扰误判、起止时间错判、干扰幅度计量不精确等问题。针对上述问题,对数据进行复核和校对,应用“缓变台阶”功能重新处理,并加强对H、D分量干扰特征的研究。

Abstract:
To improve the preprocessing quality of the Shandong geomagnetic network data which were disturbed by High Voltage Direct Current(HVDC)transmission,we summarized and analyzed the preprocessing condition of the Shandong Geomagnetic Network during the disturbance by the Ningdong HVDC transmission over the years. The relative difference detection function and preprocessing function of National Earthquake Precursor Data Processing System is applied. The result shows that the Ningdong HVDC transmission disturbances are generally removed after the data preprocessing. Meanwhile,there are still some problems,such as misjudge of the HVDC transmission disturbance,misjudge of the beginning and ending time of the disturbance,inaccuracy preprocess of the disturbance magnitude,etc. Corresponding solutions are proposed to the specific problems,such as the double-check of the data,slowly varying step function to reprocess,and reinforced research to disturbance characteristic of H and D.
