Abstract

The invention discloses a bad data correction method and device, a storage medium and electronic equipment. The method comprises the following steps: acquiring an initial suspicious measurement set; judging the relationship between the weighted residual error of the maximum suspicious measurement in the initial suspicious measurement set and a preset threshold value; and when the weighted residual error of the maximum suspicious measurement is smaller than a preset threshold value, correcting the state quantity based on a prediction residual error method. According to the bad data correction method and device, the storage medium and the electronic equipment provided by the invention, the initial suspicious measurement set is firstly formed by judging the measurement, then the weighted residual corresponding to the maximum suspicious measurement in the initial suspicious measurement set is calculated, and the relationship between the weighted residual and the preset threshold is judged; and correcting the bad data in the initial suspicious measurement set based on the judgment result. Therefore, the accuracy of bad data identification is guaranteed.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a bad data correction method, device, storage medium and electronic equipment. Background technique [0002] With the in-depth application of computer technology and communication technology in the power system, the digital characteristics of the power system are becoming more and more prominent. Through the high integration of advanced digital technologies such as high-precision distributed sensing and the Internet of Things and power physical systems, the digital empowerment of the power system has been realized, thereby realizing the comprehensive perception and intelligent operation of the new power system. [0003] On the other hand, due to the rapid growth of information collection devices such as sensing equipment and sensing equipment participating in the operation of the power system, as well as the grid connection of new energy sources and the increase in the lo...
