and judging whether a newly added interval, a deleted interval and a modified interval exist according to the SSD model before and after reconstruction and extension, if the newly added interval exists, updating the primary equipment state configuration again according to the state template, if the deleted interval exists, deleting the primary equipment state configuration of the interval, and if the modified interval exists, regenerating the primary equipment state configuration again according to the new interval type and the interval primary equipment element and the state template.
4. The method for determining the overhaul reconstruction smart recorder configuration change boundary as claimed in claim 1, wherein the step of synchronously updating the primary and secondary state inconsistency configuration of the smart recorder total station configuration comprises the steps of:
synchronously adding and deleting configuration items of secondary equipment state configuration corresponding to the IEDs according to the added IEDs and the deleted IEDs, and updating the secondary equipment state configuration if station control layer data set modification exists for modifying the IEDs;
and if the primary equipment state configuration and the secondary equipment state configuration are not modified, the primary equipment state inconsistent configuration and the secondary equipment state inconsistent configuration are not modified, otherwise, the primary equipment state configuration and the secondary equipment state inconsistent configuration are required to be updated according to the primary equipment state configuration and the secondary equipment state configuration.
