The monitoring and control information acceptance process of smart substation involves many links of energy management system and substation. Based on the existing technology system, a whole solution to satisfy the whole circuit of substation monitoring and control information segmentation acceptance is proposed. The advantages of conventional acceptance and automatic acceptance are analyzed. The architecture of automatic acceptance system is designed. According to the two application scenarios of new substation and extension substation, different implementation plans are given. The realization technology of automatic acceptance on substation side is emphatically analyzed, the triggering technology of information source based on customization strategy realizes the one touch trigger of interactive information between main station and substation. Based on the idea of modularization, an integrated automatic acceptance device is developed and the experimental verification and practical engineering application are carried out. It is verified by practice that automatic acceptance technology greatly improves the acceptance efficiency and breaks through the technical bottleneck of automatic acceptance of interaction information between main station and substation. The technology of automatic acceptance has already meet the conditions of comprehensive popularization and application.
