Design And Implementation Inteligent Inverter For Grid Connected PV System

Abstract: Power generation from solar PV sources is increasing exponentially due to increased requirement of green energy. The penetration of renewable energy sources like solar Photo Voltaic (PV) and wind energy is increasing. In this study, electrical power is generate from solar energy using solar photovoltaic cell. The system is designed of PV module with associated with MPPT control DC/DC boost converters with load and connected with power grid by using 3-Φ inverter (DC-AC converter). Various control techniques are adopted to make the output suitable for controlling the converter. The Perturb & Observe (P&O) method used for the MPPT with boost converter. The PI control technique with and without Fuzzy Logic Controller (FLC) are utilized with inverter (DC/AC converter) to observe various output response and analysis of total harmonics distortion in ac output current at grid side. This study presents comparison between the PI control technique with and without Fuzzy Logic Controller (FLC) are utilized with inverter (DC/AC converter) to observe various output response and analysis of total harmonics distortion in ac output current at grid side for grid connected Solar PV system which provides a convenient choice of right technique for system.

Evaluation of a new class of eulerian's type integrals involving generalized hypergeometric functions

Abstract: Very recently Masjed-Jamei and Koepf [Axioms 2018, 7 (2), 38] established interesting and useful generalizations of various classical summation theorems for the ${}_{2}F_{1}$, ${}_{3}F_{2}$, ${}_{4}F_{3}$, ${}_{5}F_{4}$ and ${}_{6}F_{5}$ generalized hypergeometric series. The main aim of this paper is to establish eleven Eulerian's type integrals involving generalized hypergeometric functions by employing these theorems. Several special cases (known and unknown) have also been given.

Comparison of Lipid Extraction from Algae (Chlorella Species) using Wet Lipid Extraction Procedure and Bligh and Dry Method

Abstract: Microalgae are consider as fourth generation biofuel for liquid fuels. But it is very tedious task to dry microalgae followed by lipid extraction and final processing for renewable fuel production. There are several economic and processing hurdles for methods including conversion of microalgae biomass to renewable fuel. Research conducted in this study modified/optimized a previously published procedure capable of extracting Tran’s-esterifiable lipids using wet and dry algal biomass. A wet lipid extraction procedure (WLEP) and Bligh and Dry methods were used for lipid extraction. From Wet lipid extraction method we are capable of extracting 25% of trans-esterifiable lipids from wet algal biomass (84% moisture) via acid (90°C, 60 minutes) and base hydrolysis (90°C, 30 minutes) and from Bligh and dry 20% of trans-esterifiable lipids from dry algal biomass. WLEP using wet algal biomass was found capable of removing chlorophyll contamination of the algal lipid extract through precipitation step in the procedure. The capability of the procedure to extract lipids from wet algal biomass, to reduce/remove chlorophyll contamination, to potentially reduce organic solvent demand, and to generate feedstock’s for highvalue bio products is highly responsible for reducing the cost of lipid extraction procedure.

Visible light communication system(VLC) Using Diversity Technique with 4 QAM OFDM FSO Link

Abstract: VLC (Visible Light Communication) is one of the new trends in future communication. In the VLC system, we used FSO as a medium. These VLC FSO systems bring explanation directed toward congestion issues from the RF communication systems, similar frequency range scalable, price influence also mobility. However climatic environment alike smog, storm... etc, Line of sight are some of the demand trouble in realizing this system. In this paper, we designed a high speed communication system for VLC using spatial diversity using filter and amplifier. Here considered link distance is 100 m and by simulation we analyze achievable bit rate 20Gbps. This proposed system can be used for higher data rate in communication for VLC Transmitting distance can be become better by diminishing the fading in free space. Spatial diversity is specific adept techniques to decrease hazy things. In this paper, we evaluate the performance of optical to electrical power conversion, Clear constellation diagram of VLC System corresponding distance from the transmitter to receiver. The ambition hereof paper must include the Diversity technique inside VLC FSO OFDM, in case add to FSO link is created. The achievement study is finalized conclusion of Constellation diagram.

Predictive Failure Analysis of Spindle Motor & Cutting Oil Condition Monitoring of Grinding Machine using Artificial Intelligence Models

Abstract: With the advent of Industry 4.0, manufacturing industries are competing to adopt intelligent machining systems to deliver high performance in minimum possible time. Machine downtimes results in hefty production loss(s). To avoid them, we must identify their causes (spindle failure in our case) and predict their occurrences. We used vibration analysis methods to analyze wear-&-tear of spindle during running condition. Our objective is to design a low-cost smart maintenance model to predict the failure before its occurrence using Support Vector Machine model. Additionally, condition-monitoring of cutting fluid by analyzing variation in temperature of rotating spindle, pH due to Sulphur concentration has been included. Learning Vector Quantization algorithm is used for data analysis of sensors monitoring the health of cutting fluids and filter oil. Time Series Analysis has been performed on pH data to predict the pH of cutting fluid for prevention of cutting fluid deterioration. The model is tested for a good range of working conditions and results are found more promising than existing system.
