after the IED equipment safety measure entry sets are implemented, after all state change reports are received, the safety measure implementation sequence numbers and the corresponding intelligent substation secondary safety measure entries are compared with the implemented IED equipment safety measure entry sets, if the safety measure implementation sequence numbers and the corresponding intelligent substation secondary safety measure entries are the same, the IED equipment safety measure entry sets are implemented correctly, if the safety measure implementation sequence numbers and the corresponding intelligent substation secondary safety measure entries are different, an error execution alarm is given,
step 8, making a playback file, wherein the playback file comprises:
6, selecting an intelligent substation secondary safety measure entry of the IED equipment safety measure entry set, an execution sequence of the intelligent substation secondary safety measure entries, an IED equipment panel indicator light entry, a pressing plate initial state and an optical fiber initial state of the intelligent substation secondary safety measure entry, and a panel indicator light initial state of the IED equipment panel indicator light bar;
the safety measure implementation sequence number, the pressing plate state change value, the pressing plate state change time, the optical fiber state change value and the optical fiber state change time of the implemented secondary safety measure entry of the intelligent substation determined by the state change report in the step 7 are also included;
the method also comprises the steps of determining an indicator light state change value and an indicator light state change time of an indicator light bar of the panel of the IED equipment through the state change report in the step 7;
the method also comprises initial state inconsistency alarm, operation error alarm and error execution alarm;
and 9, performing playback, wherein the playback comprises two stages:
the first stage shows the intelligent substation secondary safety measure items, the execution sequence of the intelligent substation secondary safety measure items, the IED equipment panel indicator light items, the pressing plate initial state and the optical fiber initial state of the intelligent substation secondary safety measure items and the panel indicator light initial state of the IED equipment panel indicator light bars of the IED equipment safety measure item set selected in the step 6, and marks inconsistent alarms of the initial states;
and in the second stage, the implementation process of the secondary safety measure items of the intelligent substation determined by the state change report in the step 7 is sequentially displayed according to the sequence of a time axis, the pressing plate state change value, the pressing plate state change time, the optical fiber state change value and the optical fiber state change time of the secondary safety measure items of the intelligent substation are displayed, the state change value and the state change time of an indicator lamp of an indicator light bar on an IED (intelligent electronic device) panel are displayed, and operation error alarm and error execution alarm are marked.
