According to the requirements of the power system at the present stage, a high-voltage and ultrahigh-voltage substation (also called a substation) is controlled by a control center/monitoring center (also called a main station), and an on-site unattended (or less-attended) management mode is adopted. The main station can correctly receive the substation information uploaded by the telemechanical system and correctly perform corresponding remote control and remote regulation on the substation equipment, and the safe operation of the power grid is guaranteed, so that the consistency of the substation end data information and the main station dispatching end data information plays a vital role in the safe operation of the power grid. The main station and the sub-station data verification work has few innovative researches, and a manual point-to-point mode is usually adopted, namely the main station table information and the sub-station actual information are manually corrected. Such a mode is not in line with the development direction of intellectualization and automation of the intelligent substation.
The data verification process between the main station and the substation is to complete the complete check from the substation primary equipment information to the main station information according to the data requirement of the main station. The traditional substation technology is not clear enough in layering and grading, and a data equipment model is not standardized enough, so that information checking work can be completed only by adopting a power failure method. The biggest defect of the complete data verification method in the power failure mode is that the power failure maintenance state of equipment is required, the main station and substation personnel are required to be matched in the data verification process, normal operation signals of the main station are also easily interfered, input information related to primary equipment of the substation is required to be debugged, the workload is huge, information of any link is wrong, error links in the error correction process are various, and the technical requirements and the analysis level of related personnel are high. In addition, the debugging is finished for too long time, and interference signals sent by the verification information continuously exist for the master station staff in the debugging process. Based on the advanced substation model data technology, the substation data information model enables a step-by-step data information verification method to be possible without generating bottom layer data signals through the consistency description of SCD and CID files.
