Abstract
Gross errors must be detected and either deleted of corrected before carrying out the reconciliation. The proposed gross errors detection methods before mostly based on the measurement residual or constraint residual. The main problem with the test based on measurement residual is t hat t he data reconciliation procedure tends to spread the gross errors overall t he measurements, thereby failing the test for outliers. Using the methods based on constraint residual is capable to tell which node is imbalance only but can not identify where the gross error is on. In order to avoid these problems and this paper proposed a new test method based on creating measurement test and F-statistic for detecting gross errors.
