Embodiment Construction
[0052] The working principle and implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0053] Such as figure 1 As shown, this method takes the network distribution device as the center, and by analyzing and filtering the SCD file, obtains the associated configuration that needs to evaluate the state of the secondary equipment and configures it in the network distribution device. At the same time, the network distribution device receives information from Various network messages (SV / GOOSE / MMS) of the process layer and the station control layer provide various real-time information and message data after analysis for the expert analysis and diagnosis program.
[0054] The specific implementation is as follows:
[0055] 1. To study the selection method and object of the key state parameters of the secondary equipment, and put forward the requirements for status reporting from the hardware and software ...
