Abstract: Electrical energy is essentially required for industrial as well as all-round development of any country. The growing demand of electrical power for different activities has forced scientists and researchers to develop alternate sources of power generation from different sources of renewable energy. Nowadays the renewable energy sources have become more popular due to their sustainability, renewability and easy availability. One of the economical and environment friendly sources of electrical power generation is the utilization of kinetic energy of vehicles passing over speed breakers. This thesis focused towards the studies on design, modeling and simulation of an electromechanical system for producing electrical power from kinetic energy of vehicles passing over speed breakers. The Speed breaker power generation unit is driven by a vehicle on the road which acts as a prime mover for power generation. The system is described in terms of the dimensions of the rack and ratchet. The pulley structure combined with a flywheel is geared to DC generators for inducing EMF which leads to power generation. To facilitate simulation studies, mathematical model of the electromechanical system is developed under MATLAB 13B Simulink environment as well as a mutism 14 for power electronic modeling and simulation. Simulation results for power generation from kinetic energy of vehicles are obtained considering four units of rotational induction generators and two units of translational induction generators. From the simulation results it is observed that for 2000 N vehicular load and for angular speed of the generator gear ranging between 0.8-0.806 rev/sec, the generated output voltage ranges from 11.91-12 V DC. A DC to DC converter is used to enhance the generated voltage level from 11.91-12 Volts to 24 V DC and finally an inverter is incorporated to convert 24 V DC to a single phase 220V, 50 Hz AC. It is observed that the generated voltage is directly proportional to the angular speed of the generator gear. Further, it is found that the total power generated from the rotational induction generators is 691 kW while that from the translational induction generators is 8.2922 kW per day on 12-hour basis. Electrical power generation from kinetic energy of vehicles passing over speed breakers has got many advantages because it does not require any type of fuel, no pollution at any stage of the power generation process. Therefore, it is recommended that EEPCo should come forward to create prototype of the proposed system and test it for implementation on the highways for considerable power generation alternative.
