Abstract

The invention discloses a method for processing ground synthetic electric field data measured practically. The method comprises: according to a missing value writing-in rule of ground synthetic electric field data measured practically, a missing value is determined and rejected; on the basis of a Pauta criterion, determination and rejection are carried out on abnormal value segmentation of ground synthetic electric field data measured practically; the rejected missing value and abnormal value in the ground synthetic electric field data measured practically are made up by using a linear regression method, thereby obtaining ground synthetic electric field data after making up; if the ground synthetic electric field data after making up do not meet expectation, a segmentation way is adjusted and the abnormal value is made up again by using the linear regression method; and if the ground synthetic electric field data after making up meets expectation, a random interference value in the ground synthetic electric field data after making up is filtered by singular value decomposition. Therefore, the impact on the ground synthetic electric field data by measurement equipment abnormality or external environment interference can be reduced; and thus a mechanism analysis of a ground synthetic electric field can be promoted.

Description

technical field [0001] The present invention relates to the technical field of high-voltage direct current transmission, and more specifically, to a processing method and system for actually measured ground synthetic electric field data. Background technique [0002] With the continuous and rapid development of my country's economy, the demand for energy, especially the demand for power resources, continues to grow. However, my country's power resources are generally more in the west than in the east, more in the north and less in the south, and have the characteristics of unbalanced distribution and demand. Therefore, in order to realize the optimal allocation of power resources, my country takes "power transmission from west to east, mutual supply between north and south, and national networking" as the strategic goal of power grid development. This means that large-scale, long-distance, and high-efficiency power transmission projects need to be built, and HVDC technology...
