Design and Development of Intelligent Substation Cluster Measurement and Control Device Based on Virtualization Technology

The measurement and control device of intelligent substation generally adopts a single set of independent configuration scheme. When the device is abnormal, the measurement and control function of the whole interval will be completely missing, and there is a big hidden danger in operation safety. Through the research of modular technology, virtual device technology, multi-core processor heterogeneous technology, virtual terminal mapping technology, the cluster measurement and control device is completed. In case of physical measurement and control failure, the virtual measurement and control unit in the cluster measurement and control device can completely replace its function, completely solve the problem of no backup for a single set of measurement and control, and improve the operation reliability and stability of the automation system.
