Deepika Lavanya N, Pooja Shree C.P, Raveena Elizabeth, Vandana G
Abstract:
To meet the modern day requirements of never ending fuel demand of vehicles. In present trend the scenario is mainly based on IC engines, which makes use of the crude oils. It is agreeable that it is lighter, compact and the ignition time is less and more convenient. But the main criterion which leads to the limiting the usage of such engines is the depletion of fossil fuels in present trend and in a motto of futuristic thought. This leads to the alternative thought of using three way system hybrid vehicles. This paper mainly focuses on the implementation of an ideology to minimize IC engines utility and enhance the usage of renewable sources along with the dynamo mechanism to generate back up power and usage of lithium-ion battery for more and better enhancement in back up power utility. As it is comparatively environmentally safe and can be a better choice in the future generation.

A Marker Controlled Watershed Algorithm
Hemavathy Y G, S S Vidya, Dr. H N Suresh
Abstract:
This paper is an attempt to develop an image segmentation algorithm using the marker controlled watershed algorithm. The initial low-level segmentation step is considered as the major need for the fine segmentation. This low level segmentation must be of lower computational complexity and of lower time consuming. The watershed is the movement of the water from the catchment area to the place where water sources meet. The watershed in the image is similar to the catchment basin of a height map. The watershed lines are the defined on edges, nodes and also in the hybrid lines which lie on both nodes and edges. A spatially regularized gradient is introduced in order to a tunabletrade-off between the regularity and the adherence to the object boundaries. Matlab based implementation is carried out and the results are tabulated and the results are compared with the previous implementation.
Keywords:
Super pixels, watershed, segmentation.

Boost Derived Hybrid Converter for Simultaneous DC and AC Applications using Single DC Source Supply
Abhilash M, Dr. J Satheesh Kumar
Abstract:
The paper proposes a hybrid converter topology which can supply both dc and ac loads from a solitary dc input. These topologies are derived from boost converter by replacing the controlled switch with a voltage-source-inverter bridge network. The resulting hybrid converter has lesser number of power switches to provide both ac and dc outputs with an increased reliability. And the proposed converter have better power processing density and reliability, which can be well suited for systems with simultaneous both ac and dc loads,The proposed converter in this paper, is called boost-derived hybrid converter (BDHC) as it is derived from the conventional boost converter. A modified PWM control strategy is described for BDHC.

Design and Manufacturing of Porcelain Longrod Insulator for Improved Performance of National (U) HVDC Grid
Amiya P. Goswami
Abstract:
Insulators for ultra-high voltage direct current (Âą800 kV UHVDC) transmission line should meet the dual requirement of withstanding a peak high voltage defined by the nominal system voltage without flashover as well as sustain the mechanical load derived from the conductor. Generally the insulator suffers damage due to simultaneous action of mechanical load arising out of heavy wind, lightning, power arc and electrical switching surge current. Although the line losses are minimized while the transmission cost goes down in Âą800 kV DC line, pollution performance of the insulator assumes a decisive role due to fixed grid polarity. It is overcome by improvement in the shed profile, shape and size of insulator. Based on the experience of Âą500 kV DC grid, state-owned Powergrid used ball and socket type porcelain insulator for Âą800 kV Chiriapalli - Agra, India (U)HVDC line. Cigre however recommends composite insulator made with epoxy-glass core with silicone rubber sheds which is found to have superior pollution performance initially due to intrinsic hydrophobicity that diminished in field over a period of time. In contrast puncture-proof porcelain longrod insulators provide an excellent hassle-free service with 3-5 fold increase in life. Additionally hydrophobic glaze can provide superior pollution performance over the entire life period. In this study we propose our design concepts and discuss the controls required on material and processing so as to prevent early aging of the porcelain longrod insulator in (U)HVDC.

Chandra Shekar S, Mr. Anil Kumar Bhat
Abstract:
The power obtained from the Photovoltaic (PV) system keeps on changing with solar radiation and ambient temperature because of the nonlinear voltage current characteristic, exhibited by the PV system. However, with the advancement in technology, it is now possible to obtain maximum power from the PV cell and thus overall efficiency can be improved. In this paper, Maximum Power Point Tracking (MPPT) based on Perturb and Observe (P & O) algorithm and programmable output voltage controller for PV systems has been presented. P & O algorithm improves the overall efficiency of MPPT and provides faster response, particularly during fast changing environmental conditions. The single stage buck and boost converter has been hardware modelled and by adjusting the duty cycle, constant output voltage can be obtained.

Three Phase Grid Connected Photovoltaic Power System
Jisha L K, Rubeena, Kavyashree. S, Rashmi G.R
Abstract:
A renewable energy resource can be used repeatedly because it is replaced naturally i.e., it is limitless. Example: solar energy, water, tidal. So, they represent reliable alternatives to conventional energy sources example oil and natural gas. But, the efficiency and performance of these systems are still under development. The PV systems are mostly used as they are light and easily installable. This system connection to the grid requires special conditions to obtain a high quality Electrical power system. This paper presents the interfacing of three phase grid connected PV system. DC-DC step up converter (boost converter) with maximum power point tracing (MPPT) is used to extract the maximum power obtained from the sun and transfer it to the grid. In any PV based system, the inverter is a critical component which is responsible for the control of electricity flow between the dc source, and load or grid so a voltage source inverter (VSI) is used to convert the DC power; into AC power before transferring it into the grid. A comprehensive simulation and implementation of a three-phase grid connected inverter are presented to validate the proposed controller for the grid connected PV system.

Shravani N, Navyashree N, Bhagyashree S B, Kavitha
Abstract:
This paper proposes a effective scheme for Direct Torque Control (DTC) of Brushless DC Motor. Unlike the traditional DTC where both the torque and flux must be employed in order to deliver the switching table for the inverter, the proposed DTC scheme utilizes the information of torque only. By considering particular operating principle of motor, the instantaneous torque can be estimated only by using back EMF ratio in a unified differential equation.
