The Power of the TrainOps Traction Power Algorithms

Unlike most competing products, TrainOps’ dynamic simulation algorithms capture the interaction – during each simulation computational step – of trains and the power system as conditions change along the alignment. Voltage variation at the train third rail shoe or pantograph affects train performance, so when the voltage decreases, the acceleration, velocity and location of the train are altered. Power demand of the train decreases, enabling the traction power system to partially recover from the voltage sag.

With this powerful feedback algorithm, TrainOps captures the performance loss caused by low voltages.  Similarly, TrainOps can demonstrate the impacts on the traction power system of a line blockage (such as the opening of a movable bridge) and the ability of the system to support multiple “stacked” trains restarting.

Competing products overstate the third rail or catenary voltages and currents, as well as the substation power demands, in simulations with dense train operations or contingency traction power configurations. This means that in comparison with TrainOps, voltages predicted by competing products are lower, and  currents and substation power demands are higher, sometimes unrealistically so. The powerful TrainOps dynamic simulation algorithms avoid this issue, ensuring that simulation-based capital investment decisions are the right ones.
