Increasing the efficiency of a traction electric drive for operation of a trolleybus

Calculation of Energy Losses in Trolleybus Traction Network by Instant Equivalent Circuits Modeling

“…For a given number of trains on a section, such pairs of values are randomly selected without modeling train movements. The initial dependencies of the vehicle power on its coordinate can be obtained by an experimental study of traffic regimes or on the basis of known distribution laws [14]. The advantage of this method is the ease of implementation.…”

Selection of Control Algorithms for Hybrid Electric Vehicle

“…Thus the problem of PES power management arises to keep the energy of BES in the desired limits. In the one hand, the BES should have a reserve to receive the energy generated during braking, and in the other hand it must not fall below the minimal allowed level ensuring the vehicle's ability to perform its designed dynamic properties [2,7,9,10]. Hybrid vehicle energy management strategies are discussed in the large amount of works.…”

“…In such conditions the most suitable solution is series hybrid electric powertrain without direct mechanical link between internal combustion engine and driving wheels. Its application on urban transit rolling stock is advised in [2,8,9].…”

“…A number of approaches based on different principles have been proposed, including deterministic rule-based control, fuzzy logics and optimization algorithms. In its turn the optimization approach includes linear programming methods, stochastic dynamic programming, methods of game theory and genetic algorithms [2,[5][6][7][8][9][10][11].…”
