Or the moon, consider computational accuracy and computational efficiency, different cycles are calculated into period discretization, form calculation interval collection.
3. it is according to claim 1 for the multicycle send out defeated change repair schedule Security Checking and appraisal procedure, its feature
It is：(A2), when repair schedule time span length be less than one when, judge the time between overhauls(TBO) be day, will maintenance the time started and
It is 15 minutes that end time, which is disassembled as discrete time slot, time interval,；When repair schedule time span length is a couple of days, judge to examine
The cycle is repaiied as week, will be disassembled as discrete time slot maintenance time started and end time, calculate daily morning peak, waist lotus, evening peak,
Four periods of low ebb；When repair schedule time span length is several weeks, the trouble hunt ing cycle is the moon, will maintenance the time started and
End time is disassembled as discrete time slot, the peak load period is only calculated daily, in addition, to the maximum in repair schedule time span
Load, minimum load, typical way load, are equally calculated.
4. it is according to claim 1 for the multicycle send out defeated change repair schedule Security Checking and appraisal procedure, its feature
It is：(B3), out-of-limit equipment Branch Power Flow is constrained and adds SCED models, the optimization mesh of the SCED models as operative constraint
