Abstract

Electricity is the most utilizing energy source in the world and there is a great scarcity of electricity so there is an importance to meet renewable energy targets as the generation of electricity from swell energy is undeveloped even though technology is widely available. So modification of this system concept would be helpful to development and growth of the system. The main objective of this research paper is to eliminate the difficulties being faced by the other systems and to supply continuous electricity without any fluctuations. We convert the kinetic energy of waves into mechanical energy through our mechanical arrangements in our system then it is converted into electrical energy. This system is the modification of the previous wave energy conversion system where we convert both motions of the waves i.e., both forward and upward motion wave into electrical energy. From this system we can expect continuous electricity supply.

Keywords: Renewable energy resource, Electricity generation, Wave energy conversion, Rack and pinion, Dynamometer.

Introduction

Wave energy is the one of major renewable energy source of ocean based renewable energy that uses the power of the waves to generate electricity wave energy is the periodic up-and down movement of water because of force of winds [1-3]. There are various methods that generate electricity from the ocean based renewable energy sources like tidal energy, wind energy, wave energy, ocean current energy, Ocean Thermal Energy Conversion (OTEC). The most popular methods are point absorber oscillating water column, tidal lagoon power etc., this paper is about to eliminate the difficulties faced by other methods. The main problems faced by other systems are those are completely immersible in ocean which can cause corrosion or fouling of the system those systems include complex construction and are not economically feasible. These systems cause damage to ecosystems or it maybe get damaged by the ecosystems [4-6].

The main objective of this paper is to supply or generate electricity continuously without any fluctuations, comically feasible, these system useful to supply and distribution of electricity in remote areas where it is difficult to supply [7-10].

The problems occur with other types of ocean based renewable energy electricity generation systems are

• These systems are fully immersed which can cause corrosion, fouling

• These are not economically feasible

.• Continuous power output can’t be achieved (Fluctuations are occurred)

• These systems affect ecosystems or maybe these systems may effect by the ecosystem

The proposed plant is reliable, sustainable, environmentally friendly power extraction procedure from sea waves. It includes a number of empty vessels the empty vessels get up and down randomly due to the upward wave thrust each empty vessel is connected to a crank. Cranks are attached with a single shaft empty vessel moves up and down crank facilitates this linear motion of empty vessel into the rotation of shaft thus generation of electricity takes place by connecting to gear box.

An apparatus for the conversion of the energy of sea or ocean swells this paper relates to an apparatus adapted to convert energy from ocean swells (waves) typically to electrical energy the apparatus comprises: A frame including a vertical post and horizontal beam, a first generator slid ably connected to the vertical post, a second generator slid ably connected to the horizontal beam, a first pinion.

Connected to the first generator a second pinion connected to the second generator a float a connection mechanism for connecting the float to the generators a horizontal first rack connected to the float for engaging the first pinion a vertical second rack connected to the one float for engaging the second pinion, wherein all components connected to the float are disposed at or above sea level.

Methodology

In this system we convert the buoyancy force of wave into electric energy. The buoyancy force of waves acts on the float this cause the float to move upward or downward and forward or backward [11].

As our system contains rack and pinion gears connected to the float. The pinion gear is connected to the generator. Any cause of motion of float either upward or forward that linear motion will be converted into rotary motion through our mechanical arrangements (Figure 1).

Working Principle

Figure 1: Working schematic flow chart.

In this system the buoyancy force causes the float to move in either of vertical or forward direction our mechanical arrangements in the system capture the motion of the float and convert that kinetic energy into mechanical energy as we connect dynamometer to the pinion gear [12]. We convert the mechanical energy into electrical energy Figures 2 and 3.

Design and Modeling

Analysis

Analysis is main part of the project to determine stress, strains, pressures acting on the arrangement of our mechanism in our wave power energy [13] generation system, mainly acting on the float, rack and pinion, sliding of the holding rod and stand Figure 4.

Figure 4: Design after assembly and simulation is to convert the CAT.

Firstly, the main design after assembly and simulation is to convert the CAT part product into the file to transfer into the geometry file of the Ansys software in the static structural in analysis systems and to we have the engineering data, geometry, model, setup, solution, result [14,15].

Meshing

Figure 5: Meshing is to cut out the part meshing.

Meshing is to cut out the part into the similar no of the shapes, generally now meshed our parts into the triangular meshing Figure 5.

Fixed Support

It is basically hinged at the bottom of the setup and it acts actually main components to move on the basis of the fixed stand main stand also called as frame consists of holding two steel rods and also support provided for the multi meter setup Figure 6.

Figure 6: Hinged at the bottom of the setup.

Hydrostatic Pressure

Waves produces the pressure hydrostatic pressure and its acts on the surface of the contact which is on the wave float downward surface and the pressure which is acting on the float helps the float to displace in the vertical and horizontal directions Figure 7.

Figure 7: Waves produce the pressure hydrostatic.

Displacements

There are two way of movements of the float vertical and horizontal displacements that we act in our project horizontal movement occurs when the waves transmits across the float it hit the side of the float and displaces the rack and pinion mechanism in horizontal direction. Horizontal movement occurs when the waves transmits across the float it hit the side of the float and displaces the rack and pinion mechanism in horizontal direction Figures 8a and 8b.

Figure 8a: Vertical displacements movements of the float.

Figure 8b: Horizontal displacements movements of the float.

Rotational Velocities

Velocities of the pinion basically called as the rotational velocities in both the pinions, generally it is measured in rad/sec also called angular velocities. Thus we need to obtain rated speeds for the power generation in the generators Figure 9.

Results

Total deformation is the deformation option that you can see all the deformation results related to your model, in three coordinates(X, Y and Z) Figure 10.

Figure 10: Total deformation.

In directional deformation, you can select a coordinate (X,Y or Z) to see the deformation result of your physical model in this direction Figure 11.

Figure 11: Directional deformation.

The equivalent elastic strain is defined as the limit for the values of strain up to which the object will rebound and come back to the original shape upon the removal of the load Figure 12.

Figure 12: Equivalent elastic strain.

This theory assumes that failure occurs when the maximum strain for a complex state of stress system becomes equals to the strain at yield point in the tensile test for the three dimensional complex state of stress system Figure 13.

Figure 13: Max principal elastic strain.

Normal strain occurs when the elongation of an object is in response to a normal stress (i.e. perpendicular to a surface) and is denoted by the greek letter epsilon Figure 14.

Figure 14: Normal elastic strain.

Equivalent Stress theory also called distortion energy theory or von- Mises theory states that maximum equivalent stress at stress elements on material or part must be smaller from the yield strength of that used material Figure 15.

Figure 15: Equivalent stress.

Maximum principal stress or major principal stress is the maximum value of normal stress acting on one of the principal planes where the value of shear stress is zero Figure 16.

Figure 16: Max principal stress.

Shear strain is the relative displacement in ratio of any perpendicular layer distance from a fixed layer Figure 17.

Figure 17: Shear elastic strain.

Normal stress might be useful is when you request stress on a surface that represents the cross-section of a part in tension Figure 18.

Figure 18: Normal stress.

Strain energy is stored within an elastic solid when the solid is deformed under load. In the absence of energy losses, such as from friction, damping or yielding, the strain energy is equal to the work done on the solid by external loads Figure 19.

Figure 19: Strain energy.

Shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress Figure 20.

Figure 20: Shear stress.

The minimum and maximum values of the all the deformations, stresses, strains, strain energy ranges we have calculated under the fluid density 1000 kg/m3 and the magnitute of 20 rad/sec in the rotational velocities of the pinions. Thus the results from the analysis helps us to the find out the pressure and placement of our setup in the ocean above the waves.

The power obtained upon testing the prototype on the wave genration setup is about 24-30 volts of voltage is generating in the setup. If we increase the scale as we go the main power system we can achieve upto 250 volts of voltage power in the system by the tidal energy.

Scope and Conclusion

As there is increase in demand for the electricity from renewable energy, to meet the necessary targets this system can be useful, In future this could be the major source of electricity generation. This system can be useful for supply of electricity for remote areas and can decrease the scarcity of electricity.

In this system we used both vertical and forward motion obtained from waves as the modification previous systems, so we can expect more efficiency than the previous systems, this system contains simple construction and more reliable. The analysis of float useful in the fabrication of the system as we can eliminate the failures of the system.
