When the 'four remote' information table of the transformer substation is established in the early stage and does not form the standard specification, the signal names of the dispatching systems transmitted by the transformer substation are not standardized and incomplete, the signal descriptions with the same meaning are different, the dispatching systems transmitted by different transformer substations are described differently, and meanwhile, key accident signals are not transmitted and dispatched, so that great trouble is brought to dispatching operation. Therefore, the non-standard signals of the substations need to be checked, and the names of the signals describing the non-standard signals and the missing key signals need to be found out and modified.
At present, a method for checking four-remote signals by operation and maintenance personnel of a power grid dispatching automation system is to perform text analysis on the four-remote signals one by one to understand meanings, if the description and the meaning of the four-remote signals are similar or similar to those of standard signals, the four-remote signals are signals meeting requirements, and if the description and the meaning are far away from each other or are missing, the four-remote signals are considered to need to be rectified. Because the rule of the method has no determinacy, the method is difficult to realize in a program mode, manual checking is usually adopted, the working efficiency is low, the accuracy rate has uncertainty of human factors, and the method needs to work repeatedly after the standard is updated.
