INDIA. Economic analysis has been done at Mantralaya buildings, regarding generation of electricity from solar power plant, electricity exported to grid, electricity utilized in mantralaya buildings, electricity imported from CSEB in KWh, amount of imported power as electricity bill, rebate for exported power in Rs.(As per electricity bill) and the total payable amount. As more attention is being focused on the development of renewable energy resources widely in Chhattisgarh state, technical and economic assessment has been done. These assessment are based on the field and the actual performances of the renewable energy conversion system. This study represents the economic analysis of 1.1MWp Capacity installed at capital complex Naya Raipur.

This paper gives a brief indication of artificial neural network and its application in power system for electrical load forecasting which can further be used for enhancement of power quality. The accuracy of load forecasts has a significant effect on economy and control of power system operations for reliable and secure operation of power system. In this paper the accurate and real time data are collected from Chhattisgarh load dispatch centre of western grid of India of year 2018. This data of power flow is simulated using artificial neural network. The purpose of short term forecasting is to satisfy as much as possible, to improve prediction accuracy.</p> Dr. Mithilesh Singh, Dr. Shubhrata Gupta ##submission.copyrightStatement## http://csvtujournal.in/index.php/rjet/article/view/81 Mon, 27 Jan 2020 14:12:34 +0530 Influence of Particle Size of Fine Aggregate on Filling Ability and Segregation Resistance of Self-Compacting Concrete http://csvtujournal.in/index.php/rjet/article/view/75 <p>This paper presents the study of the influence of particle size of fine aggregate on the filling ability and segregation resistance of Self - Compacting Concrete (SCC). The filling ability was assessed from the results of mortar spread diameter by mini truncated cone and the segregation resistance was assessed from the results of mini V-funnel flow time of mortar fraction of SCC as per EFNARC guidelines. 8 mixes of mortar fraction of SCC consists of two different cement replacement percentage (CRP) by fly ash are investigated for four different particle sizes of fine aggregate.</p> Ankush Gupta, Rajeev Chandak, M.

The joint between two metals can be formed through the combined action of frictional heating and mechanical deformation which is developed due to a rotating tool. The material that flows around the tool undergoes an extreme level of plastic deformation. Rotation generates enough friction and the friction generates sufficient heat to plastify the material. Friction Stir Welding (FSW) is handy for welding aluminum alloys. However, interest is growing in utilizing the process in a wider range of applications that also employ non aero engine metallic materials. Therefore, it is the objective of <br>this report to provide a broad view of the capabilities of the FSW process for joining metals. This review paper will cover the various work performed on friction stir welding, and the basics <br>of the process and the fundamental aspects of operating an FSW. This includes a description of the different parameters that have been involved in this process. And also studied the material <br>flow, forces, and other output responses, including defects, and strain rates that is produced.</p> Hari Dewangan, Atul Chakrawarti ##submission.copyrightStatement## http://csvtujournal.in/index.php/rjet/article/view/78 Mon, 27 Jan 2020 14:14:13 +0530 Performance Analysis on Flow Through S Shaped Diffusers http://csvtujournal.in/index.php/rjet/article/view/76 <p>Many times due to space limitations&nbsp; it is necessary to decelerate and turn fluid simultaneously. For such requirement curved diffusers are being used. Five S shaped diffusers of turning angle 120<sup>o</sup> were fabricated. The area ratio was 2.5, 3.5, 4.5, 5.5 and 6.5. The pressure on the outer wall is more than that on the inner wall in the first curvature and less in the second curvature. Variation in actual pressure recovery coefficient (Cp) and pressure recovery efficiency<strong> (</strong>η) is not very much within the range of Reynolds number tested for a particular diffuser. As area ratio increases value of Cp and η also increases. The optimum area ratio for 120<sup>o</sup> diffuser is 4.5.&nbsp;</p> G. K. Agrawal, U. S.

It belongs to the class of difficult to cut material because of its unique properties such as high strength, high hardness and toughness including good corrosion resistance. The present study deals with comparative analysis of hole quality, surface roughness and chip characteristics when drilling 17-4 PH stainless steel with uncoated and coated solid carbide drill bits. Dry drilling operation was carried out at two different feed of 0.10 mm/rev and 0.15 mm/rev with a constant spindle speed of 2000 RPM. Results indicated that surface finish and burr thickness could not be improved, while remarkable reduction in hole diameter and delamination factor was noted for the coated solid carbide drill bit compared to its uncoated counterparts for different machining conditions.</p> Sharda Pratap Shrivas, Aruna Thakur ##submission.copyrightStatement## http://csvtujournal.in/index.php/rjet/article/view/71 Mon, 27 Jan 2020 14:18:47 +0530 Design of D-STATCOM for Power Quality Improvement in Wind Power Systems http://csvtujournal.in/index.php/rjet/article/view/72 <p><strong>Abstract: </strong>The study of problem is when high value reactive load adding or removing that time voltage sag and swell we are trying to removing sag and swell we can say that stable for all time.&nbsp; The D-STATCOM ac current mode activities in active and reactive current are suppressed by mode shape; along these lines fortifying the receptive current exercises on the heap transport voltage guideline. It can be clearly seen from the obtained results that the voltage attains stability after a short surge even on sudden change in load conditions. The aforesaid conditions have been verified by both load addition and load removal.
