Improved Modelling of Wind Turbines on Trains

Most wind powered electricity generation systems are stationary and heavily dependent on the speed and direction of the wind. Alternatively, the wind displaced by fast moving vehicles and particularly by trains is routinely available in locations worldwide. Previous research has been aimed at designing wind turbine models that maximize the output potential of the system. However, there are significant limitations in those turbine models. For example, i) the total drag force acting on the moving train can be significantly increased, and consequently normal operation can be compromised. The traditional turbine models do not take this effect into consideration; ii) The potential for energy gain gas been considered only during deceleration of the train. To overcome these inherent drawbacks, this work aims to develop an improved and more realistic wind turbine model on the trains. Through extensive simulations, the effectiveness of the proposed turbine model has been demonstrated
