6 FAQs about [Energy storage function of the isolation trolley]
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.
Do trolleybuses have AC traction drive systems?
The most important feature of trolleybuses that are equipped with AC traction drive systems is the ability to generate electrical braking energy. Instead of dissipating in brake resistors, this regenerated energy can be either transferred to other accelerating trolleybus or stored in energy storage system (ESS) for repeated use.
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 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.
Do electric trolleybuses generate electrical braking energy?
Abstract:Electric public transport infrastructure with its electric trolleybuses plays an important role in large-scale consumption of electrical energy. The most important feature of trolleybuses that are equipped with AC traction drive systems is the ability to generate electrical braking energy.
What factors determine a trolleybus movement?
A trolleybus, as opposed to rail vehicles, does not have dedicated lanes and moves along the road with other road vehicles. Hence, a factor determining a trolleybus movement is theimpact of other road users. Moreover, the number of speed limits on the road is greater than in the case of rail traction.
