And S240, if the sub-processors receive the GOOSE message or the MMS message, exiting the virtual measurement and control device.
Specifically, after the sub-processor starts the virtual measurement and control device, if a GOOSE message or an MMS message is received, the sub-processor exits the virtual measurement and control device. And when the sub-processors receive any one of the GOOSE message and the MMS message, the sub-processors can quit the virtual measurement and control device and continue to adopt the entity measurement and control device to execute the measurement and control function. The exit of the virtual measurement and control device in the embodiment better meets the requirement of automation.
And S250, continuously adopting the entity measurement and control device to execute the measurement and control function.
And if the sub-processors determine that the redundant starting conditions are not met, the virtual measurement and control device does not need to be started, and the entity measurement and control device is continuously adopted to execute the measurement and control function.
The method comprises the steps that the state information and the measurement and control configuration files of corresponding entity measurement and control devices are obtained through sub-processors, the sub-processors determine whether the entity measurement and control devices meet redundant starting conditions or not according to the state information, if yes, virtual measurement and control devices corresponding to the entity measurement and control devices are started based on the measurement and control configuration files, and if the sub-processors receive GOOSE messages or MMS messages, the sub-processors exit the virtual measurement and control devices; if not, the entity measurement and control device is continuously adopted to execute the measurement and control function.
