Development of a smart substation cluster measurement and control device based on interval function dynamic deployment

The smart substation cluster measurement and control device adopts a common software and hardware platform and process bus technology, based on IEC 61850 standard, and integrates the multiple interval measurement and control functions of the smart substation. Adopting the plug-and-play concept, the bay design is oriented, the physical measurement and control device is virtualized, the bay function is dynamically integrated and deployed flexibly, adapting to different application scenarios of smart substations, and meeting the convenience requirements of reconstruction and expansion. By configuring "single bay physical measurement and control device + cluster measurement and control device", each virtual measurement and control unit in the device corresponds to the single bay physical measurement and control device. After the physical measurement and control device fails, it will automatically switch to the corresponding virtual measurement and control unit in the cluster measurement and control device. The centralized backup of the measurement and control function of the smart substation is realized. Test verification and engineering applications show that the cluster measurement and control device shortens the time that equipment failure causes the measurement and control function to fail, and improves the reliability of the smart substation automation system.
