From the example of the case #1, it can be concluded that the gen-sets are swapped after the
duration determined by following formula:
SwapTime = Second lowest considered running hours
– Current lowest considered running
hours + #RunHrsM1
Case #2:
Gen-set 1 running hours = 0 -> running hours considered in RHE = 0 (0-RunHoursBase)
Gen-set 2 running hours = 0 -> running hours considered in RHE = 0 (0-RunHoursBase)
Gen-set 3 running hours = 0 -> running hours considered in RHE = 0 (0-RunHoursBase)
Each gen-set has the same RHE = 0 h. By applying the SwapTime formula, we get the run time of
gen-set 1 before next swapping:
SwapTimeG1 = 0
– 0 + 10 + 1 = 11
Similar way, we get the run time of gen-set 2 before next swapping:
SwapTimeG2 = 11
– 11 + 10 + 1 = 11
