As the world’s largest power grid enterprise, State Grid has migrated its core smart grid dispatching & control system from Oracle to Kingbase. The system has maintained stable operation for 17 years ever since the migration.
How State Grid Corporation revamped their nationalal power grid management system
State Grid Corporation of China is the LARGEST power grid enterprise in the world, ranked 2nd.
In 2008, State Grid rolled out a new enterprise-grade converged database to upgrade its power grid dispatching system for a key national nuclear supporting infrastructure initiative.
Integrated collection, management, and monitoring functionality.
High-frequency, continuous, and reliable data entry.
High-security requirements: Level 4 security of the Ministry of Public Security.
Customized needs: Wide table support, high concurrency and throughput, cross-regional synchronization.
Migration requirement: Original Open3000 system based on Oracle, required migration.
Overcoming limitations of the legacy system
As the backbone of China’s national power infrastructure network, State Grid Corporation of China demands absolute system reliability with zero tolerance for service downtime. The platform is required to process massive volumes of data streamed from millions of IoT sensors deployed across the entire power grid.
