Dynamic investigation of traction electro drive systems with combined power source

The most important problem when economical autonomous transport means are created is stabilization of accumulated battery (AB) current. It is connected with the fact that discharge of AB by constant current improves working conditions and increase useful energy intensity, given by AB. It is suggested to use this for the stabilization of power buffer store (PBS). When transport mean is accelerating, load peaks are smoothed out by discharging and when it is decelerating, by charging of PBS. So surplus and shortage of energy are paid of by PBS and current stabilization takes place, because of it discharging time is increasing. Traction electro drive is described by set of non-linear differential equations, analytical decision of which is difficult and mathematical modeling method is used. To use the method mathematical models of all elements of the system are necessary.
