Design Method of Intelligent Substation Configuration File Security Control System Based on AOP and MVC Architecture

A smart substation configuration file security control system based on AOP and MVC structures is proposed to address the issue of close coupling between traditional intelligent substation configuration file security logic and business logic, resulting in complex and difficult to maintain systems. Firstly, an analysis was conducted on the configuration file process, lifecycle process, and control technology within the intelligent substation. Then, based on this, the design models of AOP structure and MVC structure were analyzed separately, and the traditional MVC pattern was improved based on AOP. A configuration file structure based on AOP and MVC structure was designed. Finally, the proposed method was compared and analyzed with the other three methods under the same database conditions through system testing. The results show that the proposed method achieves the minimum average response time (RTT) and memory occupancy rate (MU) under the same experimental conditions, and under large data volume, the response time is not more than 5 seconds, and the memory occupancy rate does not exceed 75%. Its performance meets user requirements.
