Then, the electric train load state estimated in the power-supplying section of each S/S can be used to simulate the system with extended feeding conditions-which is challenging to evaluate and verify in the field-through software-in-loop simulations. The algorithm first estimates the power consumed by the load and the location of the load based on actual measured data under normal power supply conditions. Therefore, in this paper, we propose an algorithm to estimate the net supplied power accurately from the viewpoint of the S/S over a specific time interval. However, it is difficult to measure accurately or predict the amounts of active and reactive power consumed by the load and the location of the load owing to the nature of the moving train load. Accurate load modeling is thus required to design realistically the capacity of a subway S/S in consideration of the extended feeding conditions. Our solutions provide the performance, simplicity, and safety that engineers and researchers desire.Electric railway system substations (S/Ss) extend the power supply distances under extended feeding conditions to maintain continued service in the event of a failure in an adjacent S/S.
