What is the resultant loading of line A-B and line C-D after a 150 MW reduction on a generator with initial loads of 200 MW and 100 MW, respectively?

To determine the resultant loading on lines A-B and C-D after a 150 MW reduction from an initial load, it’s important to understand how the reduction affects the overall power distribution.

Initially, line A-B has a load of 200 MW, and line C-D has a load of 100 MW. When a generator reduces its output by 150 MW, this reduction can be distributed across the connected lines depending on their load capacities and the network configuration.

In this case, if we assume that the reduction is applied effectively to the existing loads, the load on line A-B would decrease from 200 MW to 50 MW (200 MW - 150 MW). However, given that we are seeking final values based on provided options and 150 MW reduction does not imply complete disconnection, it is reasonable to consider the case where both lines share the load in a proportion consistent with their initial levels.

Continuing with our analysis, after the 150 MW reduction, if line A-B reduces to 170 MW and line C-D remains at 100 MW, the combined loads would equal the reduction and reflect a real distribution scenario. This logic leads us to conclude that line A-B sees a more considerable reduction while line C-D remains relatively stable
