Energetic optimization of regenerative braking for high speed railway …
The recovered energy shows a maximum in correspondence of a 20% braking request; however, this low value of the braking request involves that the braking distance and the braking time (respectively reported in Fig. 22, Fig. 23) are quite high, beyond the acceptable limits usually considered in high-speed applications.
Full article: Power quality in high-speed railway systems
On the basis of the model of the TPSS, the power flow can be calculated. The high-speed railway is a nonlinear system, so the iteration method is applied to solving the power flow problem. There are two main methods for iteration: Newton–Raphson method and train-timetable method. 1) Newton–Raphson method.
