A Novel Model for Wind Turbines on Trains

Abstract

Wind turbines that are consistently exposed to the air displaced by moving trains have a high potential for energy generation. Researchers have developed mathematical models to simulate wind energy generation from turbines on moving trains but there are significant gaps in the developed model theory. Most models do not consider the negative effects that additional aerodynamic drag, increased weight, and modified dimensions can have on the train’s operation. To overcome the drawbacks of existing models, this work proposes a novel approach of modeling the wind turbines on trains by considering wind turbine exposure only when the train is decelerating or stationary. There are no models that consider all of these realistic physical effects as a function of time. Real-time analysis and power-system simulations showed that the proposed model could produce over 3 MJ of net energy for favorable train trips. The simulated load profile met the demand of a 1 KW generator connected to onboard electrical components. Some recommendations on possible future research on wind turbines on trains are explained.

“…This electricity can then be used to power the train's lighting and air conditioning and other systems [11][12][13][14]. • Wind power (not widely used in trains yet): Wind turbines can be installed on the roof or sides of trains to harness the power of the wind and generate electricity [15][16][17][18][19][20]; however, detailed analyses are needed since the wind turbine could slow down the train.…”
