With the rapid development of smart grid, the number of smart substations is increasing, and the establishment of a unified security isolation container is beneficial to the realization of unified information modeling and data management of the whole station, so the application research and development based on security isolation container is inevitable. The invention relates to an intelligent alarm APP system based on a safety isolation container established on the basis of a unified platform, which acquires alarm information data from the platform through an interactive information interface between the platform and the APP, forms a knowledge base based on fault logic description language modeling, and finally calls the interactive information interface between the platform and the APP to transmit inference information to the platform after fault reasoning and diagnosis. The practice shows that the intelligent alarm APP based on the security isolation container can perform independent start-stop operation, independent process white list, network white list and other security settings, and can intelligently process the fault information in real time and reliably, and support the integrated operation control and independent safe and stable operation of the smart grid.

Through analyzing the data characteristics of the typical business of the substation, an in-depth analysis of the need for safety isolation in the substation is carried out. After studying the change of substation demand and safety requirements, the model of open platform and specialized APP of monitoring system was proposed, then a three-in-one integrated management basic platform was designed to realize the integration of scientific modeling, data collection and data management of the whole station information. The platform provides standardized service access interfaces for resource management, data management, public services and application management, enabling flexible expansion of various applications. It effectively utilizes its own technical advantages in its professional field, makes it more convenient for functional applications to be integrated into the monitoring system and makes it more promotes the intelligent development of substations.
