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.
