Research on Centralized Backup Technology for Measure and Control in Smart Substation

The cluster measure and control device based on the technology of virtualization, redundancy migration, reservation principle and model equivalence principle, has solved the problem such as the non-redundancy of the measure and control device in smart substation. The device can achieve the function of backup redundancy in smart substation and ensure the normal operation of the monitoring system in case of breakdown of the conventional measure and control device. The cluster measure and control device has been applied in some substations and is in good condition.
