Question
Assume that all transmission lines LOW and HIGH limitation capacity is limited to 80MW. Given the initial transmission system loading on
line 1-2 as 48 MW and line 1-5 as 68 MW, LODF1-2, 1-5 = 0.3913, PTDF1-5, 1-2 = 0.1195. Calculate contingency flow on line 1-2 due to outage
in line 1-5 and indicate if the line will be overloaded or not.
Select one:
O a. PF1-2, 1-5= 77.6 MW, Not Overloaded
O b. PF1-2= 74. 6 MW, Not Overloaded
O c. PF1-5 = 86. 8 MW, Overloaded
O d. None of these
