Service restoration instruction matrix H2:
In formula: siIndicate interconnection switch and distributed electrical source switch；It indicates to interconnection switch and distributed electrical source switch
Instruction operation；1 indicates that switch closes；0 indicates that switch is opened, i.e., is powered recovery to non-faulting section.
Control failure executes matrix by control instruction to construct, including Fault Isolation executes matrix and service restoration executes
Matrix；For control instruction, setting control tripping and malfunction failure.
24) information forecast failure and corresponding physics forecast failure form information-physical combination forecast failure.
Step 3, according to preset rules, required information-physical combination is filtered out in information-physical combination forecast failure
Forecast failure.
Based on information-physical combination forecast failure, fault recovery rate is calculated, is ranked up, filters out according to ascending
Information corresponding to fault recovery rate less than threshold value-physical combination forecast failure.
