Research on Online Software Management System of Intelligent Substation Based on Two-layer Architecture of Regional Station Domain

For the problem that the secondary equipment configuration of intelligent substation has a large workload and the software version used does not have full process management, an online software management system is proposed. Firstly, the substation software management and control architecture of the two-layer architecture of the regional station domain is proposed. Then, the system functions, software management processes and application scenarios are elaborated and analyzed. This system can manage the life cycle of the software of the secondary equipment of the intelligent substation, ensure the accuracy of the whole process of the intelligent substation equipment software version, improve operation and maintenance efficiency, and realize the stable and reliable operation of the intelligent substation.
