This paper presents the single phase multilevel inverter which is used in power transmission network side to overcome the voltage sag and swell problems. In this project we are handling two approaches for DC to AC power conversion. First one is cascaded H-Bridge inverter and second one is Multi level scheme with level modules and H-Bridge. Here two approaches Total Harmonic Distortion of output load voltage, active power and reactive power are compared. The Total harmonic distortion produced by second scheme is better than first scheme. Active power and reactive power produced has larger value in Multi level modules with H-Bridge Inverter. © Research India Publications. Source

The tensile, flexural, impact and abrasion loss behaviors of Al2O3 impregnated coir fiber-reinforced polyester composites are evaluated. The short untreated coir fibers are used as reinforcements in polyester matrix. The effects of fiber length, fiber diameter and filler content on the mechanical properties of alumina-coir-polyester composites are studied by developed regression models in this investigation. The optimum parameters for better mechanical properties are determined using response surface methodology approach. Source

The renewable energy potential of coastal areas of Tamil Nadu, India ranks along with the utmost in the world. This study proposes optimization and cost of energy of different hybrid renewable energy system to power a health clinic in that building. The National Renewable Energy Laboratory (NREL) optimization computer model for distributed power, "HOMER," is used to estimate the optimization and its cost of energy. The implementation of RE systems to supply Rural Health Clinics will contribute to reduce both electricity generation cost and to reduce the consumption of fuel while improving health care and quality of life in these isolated coastal regions. We conclude that using the PV+Wind+Diesel+Battery system for these types of applications in justified on technical and economic grounds. The experimental results show that the least cost of energy at Rs 5.00/KWh, is obtained from above said system and also experiment result shows that the COE decreases with 0% of interest. It is noted, that the PV+Wind+Diesel+Battery hybrid system shows the lowest COE and high amount of Renewable energy. © Maxwell Scientific Organization, 2014. Source

A few composite ion exchangers were prepared by blending sulphonated carbons (SCs) prepared from plant materials, such as Phyllanthus emblica, Linn.(PE), Eugenia jambolana, Lam.(EJ), Terminalia chebula, Retz. (TC) Terminalia bellarica, Roxb. (TB) and Achyranthes aspere, Linn.(AA),blended with phenol-formaldehyde resin (PFR) in different weight ratios (from 0 to 50% w/w). These, SCs were partially blended into the polymeric matrix of Phenol-Formaldehyde sulphonic acid, which could be used as new cheap/low cost ion exchangers (IERs) for the removal of some selective metal ions. CEC of selective single metal ions (Cu2+, Zn2+, Pb2+ and Ca2+) and binary mixture metal ions such as (Zn2++ Cu2+ and Pb2++ Ca2+) and were determined for using PFR, composite resin with different %(w/w) of SCs and 100% SC. Binary mixture of resins(R1 and R2) were prepared by mixing of two low cost IERs obtained by blending PFR with 20% SC(prepared from plant materials PE,TB, and AA) which possess high and low CEC value. CEC of selective single and binary metal ions for the binary mixture of resins (R1 and R2) was determined. It shows that composites/low cost IERs up to blending PFR with 20% (w/w) SC, retains the CEC of the original PFR. CEC values were theoretically calculated using linear or additive (ideal) behaviour and found to be less than that of the observed values of CEC for all the ion exchange systems. This may be due to synergism modified ion exchange process. © 2013 RASĀYAN. All rights reserved. Source

With the increasing threat to environment and the fast depleting fossil fuel resources, hybrid power systems consisting of two or more renewable energy sources such as solar PV, wind, biomass, ocean thermal-with or without the back up of diesel generator have come to the forefront. These hybrid systems are normally integrated with battery banks for total reliability; such systems have brought about better quality of life in remote areas of developing economics. The remote areas in the state of Tamil Nadu in India possess excellent renewable energy sources. These areas fall under different climatic zones, are sparsely populated and are in the process of development. Though these areas are connected to the grid, Tamil Nadu grid is not stable; it is currently experiencing 40% short fall in generation. Thus grid power is available to these remote areas only for 10 h a day and even when available, there are voltage frequency problems. This paper analyses the economic feasibility of installing and operating hybrid systems in these areas. The areas are divided into different climatic zones and the hybrid system economy is analyzed for each climatic zone on the basis of NPC (net present cost), consumption of diesel and renewable fraction for all climate zones. The analysis indicates that the interior climatic zone - the area would be the optimum climatic zone to install HPS PV/diesel. The sensitivity analysis proves that the NPC of such a system can be reduced. It is suggested that due to high initial cost, government subsidy is necessary to adopt the system on a large scale. Such a profit will encourage development of renewable energy utilization and bring about rapid development of these remote areas. © 2014 Elsevier B.V. All rights reserved. Source
