Image 5.23 Run hours equalization - case #1
Step 0 1 2 3 4 5
RHE1 100 211 211 233 233 255
RHE2 200 200 222 222 244 244
Run G1 (ΔRHE1) 0 111 0 22 0 22
Run G2 (ΔRHE2) 0 0 22 0 22 0
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 + #Run Hours
Max Difference (page 200) +1
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
Finally, we get the run time of gen-set 3 before next swapping:
SwapTimeG2 = 11 – 0 + 10 + 1 = 22
Please refer to figure below to understand the evolution of RHE of gen-sets in this particular case.
