6 FAQs about [Principle of Energy Storage Power Supply for Trolley Cases]

Can a stationary supercapacitor save energy in a trolleybus traction network?

The aim is to determine potential energy savings in the power supply system of the trolleybus traction network. The use of a stationary supercapacitor energy storage device and the reconfiguration of the power system was compared.

Why is installation of energy storage system easier in new trolleybuses?

Installation of energy storage system is easier into new trolleybuses in terms of technical challenges, because the proportion of the energy storage system can be already considered at trolleybus design and manufacture.

How to eliminate voltage oscillations in trolleybus propulsion system?

In order to eradicate voltage oscillations in the power supply system, the power of the trolleybus propulsion systems isreduced when there occurs an excessive voltage drop in the power system. It involves power reduction which is proportional to the value of voltage drop.

Can a full recuperation energy balance be applied to a trolleybus traction?

Research on the analysis of the full recuperation energy balance are relatively rare, e.g. a riveting research paper is presented in , but it concerns the underground power system and its resultscannot be applied to the trolleybus traction.

How much energy does a trolley battery use?

As can be seen from Tab. 2.1, the battery is dimensioned for high energy – apparently for the purpose of long independent driving without the need for a trolley supply. In the study and in other documents concerning the TROLLEY project, information about average energy consumption of 2.5 kWh/km can be found.

How much energy does a trolleybus use?

In the study and in other documents concerning the TROLLEY project, information about average energy consumption of 2.5 kWh/km can be found. Note: Our study comes to the number of 1.3 kWh/km. This result was obtained from a measurement on a smaller and lighter trolleybus 21 Tr, see Chap. 4.2.4, equation (4.8).
