Reliability Study of Redundant Switching in Power Grid Dispatch Automation Systems

To address issues such as delayed fault detection, high switching latency, and poor coordination in redundant switching of power grid dispatch automation systems, a multi-level redundant switching architecture was developed to enhance system operational continuity. Techniques including storage active-active, database virtual volume mapping, LAN redundancy optimization, and distributed application multi-node collaboration were employed. The implementation pathways and parameter configurations for each technical level were clarified to achieve seamless fault switching, resolving pain points of traditional redundancy technologies like single-point failures and configuration conflicts. The proposed solution demonstrates strong operability and practical application value, providing technical support for redundant construction in industrial field dispatch automation systems.
