What is the loading on the shortest remaining line after one line trips, if initially loaded at 200 MW?

• A. 400 MW/Yes
• B. 400 MW/No
• C. 300 MW/Yes
• D. 300 MW/No

Answer: (D)

To determine the loading on the shortest remaining line after one line trips, we need to consider the implications of a line trip on the system's load distribution. Initially, if a line is loaded at 200 MW and one line is taken out of service, the remaining lines must accommodate the load that the tripped line was carrying, which includes any additional load that may have been on the other lines prior to the trip. When one line trips, the overall system load does not decrease; rather, it is redistributed among the remaining lines. If we consider the scenario where the initial load on the remaining lines was sufficient to handle only the 200 MW, they would need to take on an additional load equal to what the trip line was carrying, which could push their total loading higher. In this situation, if we determine that upon redistribution the loading on the remaining line shifts to 300 MW, then that indicates a balanced approach to distributing the load while ensuring reliability in the operation of the power system. The importance of keeping the load within the safe operational limits for the remaining lines is crucial to maintain system reliability and prevent further trips. Moreover, an additional context includes ensuring compliance with NERC's standards, which focus on maintaining system reliability even under stressed conditions.
