The Power Management with Solar PV in Grid-connected and Stand-alone Modes
No full textAs, the use of energy increasing, the power quality requirements are also increasing. Photovoltaic panels are generally used to compensate the energy demand. Due to the characteristics of PV panels and solar irradiation, output power is fluctuated. So that battery storage system is generally used to eliminate power fluctuation problem. The battery bank is communicated with DC bus by a bidirectional DC/DC boost converter. Upper limit and lower limit of the battery storage are considered in power management algorithm to increase the life cycle of battery bank. The paper proposed power management schemes to regulate both AC and DC bus voltages. The proposed power management system is capable to regulate power for grid connected mode and islanded mode. This paper mention power management algorithm and simulation, for both grid connected mode and islanded mode. The paper mention experimental results for both condition main grid connected mode and islanded mode
An Image Fusion In Gradient Based Multi-focus Image Enhancement
No full textA dynamic picture mix plot for infrared and unmistakable course of action in light of range target ID is proposed in this paper. Target acknowledgment framework is used to divide the source pictures into target and establishment areas. Particular mix rules are gotten independently in target and establishment territories. A limitedly dreary discrete wavelet change (LR DWT) methodology is familiar with finish move invariant multi-assurance depiction of each source pictures. Blend researches genuine picture progressions demonstrate that the proposed method is convincing and capable, which fulfills best execution over the non-particular mix technique
A HYBRID DSTATCOM TOPOLOGY FOR LOAD COMPENSATION WITH REDUCED DC-LINK VOLTAGE RATING
Get PDFThe Distribution Static Compensator (DSTATCOM) is mainly used for compensation of load in low voltage distribution system. The study proposes a Hybrid DSTATCOM topology that consists of a three-leg VSI with neutral clamped split capacitor to compensate unbalanced and non-linear loads. The scheme is employed with a series capacitor along with the interfacing inductance and a shunt capacitor. This reduces the required DC-link voltage and consequently reduces the voltage stresses on DC-link capacitor, while the shunt capacitor absorbs switching frequency harmonic components on supply side. The reference currents for the proposed hybrid DSTATCOM have been derived by using Synchronous Reference Frame Theory. The performance of proposed topology is verified using MATLAB/ SIMULINK
A Polymer Studies for Insulated Power Cable
No full textIn reviewing the history of the development of power cables have gained popularity among quality of power in terms of transmission. A new class of plastic materials has been developed; the outstanding characteristics of Polymers have pre-determinable electrical conductivities and possess perfection in physical, electrical as well for mechanical properties. The supply of power with higher reliability is the main aspect of power system and trouble-free performance of power cable is extremely important in utility side. Power outage causes by failure of cable insulation to overcome all the issues the new polymer materials came in use for the improvement in power cables. Aim to search new material which can improve the environmental compliance of wire and cable in all regions of the world. The variety of uses associated with the manufacturing and installation of insulated power cable consisting a number of materials of high conductivity metals polymers base, that are extruded around the centre conductor which are having different effects in terms of performance. Present days power cables are amazingly developed with improved dielectric properties and progress has been made by adopting method of preparation
Maintaining efficiency of Biogas Energy Plant of Hybrid Model byUsing Solar Energy
Get PDFThis study proposes a use of a solar photovoltaic cell and biogas plant hybridization which subsequently used for electricity generation or some other domestic or industrial purposes. it proves to be very economic, environment friendly and improves the quality of life in small towns. Household biogas system has become an important part of energy source for rural areas in India. However, production efficiency of small household biogas plant is quite poor since its operation is seriously influenced by environment temperatur
Overview of BIG DATA and HADOOP
Get PDFBig data is huge amount of data; it is a collection of large datasets which cannot be processed using traditional data computing tools and application. It’s not a tool, application or framework, it is merely large datasets. Now a day’s various websites, web application are generating large and complex data. Processing this generated data using traditional data processing applications and tools is inadequate. Aim of this paper is to take review of Big Data and what are the challenges with managing large volume of data. This paper also gives the overview about the hadoop framework and how we can handle this large volume of data sets using hadoop framewor
Data Security Issues in Cloud Computing
Get PDFAs we are familiar that the cloud computing field is very vast and also its one of the potential field. It also has many advantages over the other storing fields. This is the only reason that the data is being migrating from the local storages to the public or the hybrid clouds. Due to some of the drawbacks the large enterprises or the critical data of the organizations are not moved to the cloud. The actual size of the cloud is much more and effective than we expect it. The data owners i.e. the cloud consumers need a high level of security regarding their data and the privacy concerns are also there. This is one of the issue that many consumers are not moving towards the cloud computing services. In this paper short but and effective analysis on the data security and privacy protection part is provided which is concerned with the data life cycle in cloud computing. The further part consists of the present work in this area. Finally the future work and the conclusion of this topic

Web Based Automation of Farm Irrigation System Using Wireless Sensor Network and Embedded Linux Board (March2016
Get PDFThis paper presents an automatic farm irrigation system using a wireless sensor network (WSN) and embedded Linux board. The system provides web interface to the user so that the user can control and monitor the system remotely. In this paper, Raspberry Pi is used as embedded Linux board which is designed based on the arm 11 microcontroller architecture. Embedded Linux board makes a communication with all distributed sensor nodes placed in the farm through ZigBee protocol and itself act as coordinated node in the wireless sensor network. The goal of coordinator node is to collect the parameters like soil moisture and soil temperature wireless. Each sensor node consists of soil moisture and soil temperature sensor and ZigBee RF antenna device for communication with a coordinator node. Raspberry Pi stores collected data in a database and analyzes the stored data. The system will work according to the algorithm developed for watering the crop. The board has a Ethernet interface and runs the simple data web server. Hence coordinator collects the data over ZigBee wireless communication protocols and allow user to monitor the data from a web browser. User can make the irrigation system ON or OFF remotely. The system will reduces the water consumptions and giving uniform water to the crop results on increasing yield
Video surveillance using raspberry Pi with particle filtering
Get PDF—One of the fundamental problem in vision is that of tracking objects through sequences of images. Within this report the design of Particle filter algorithm to track the target and show the resulting improvement in tracking. More specifically, this project described the technique of how to track Moving Object. The proposed architecture is suitable for indoors and outdoors scenes with static background and overcomes the problem of stationary targets fading into the background. Optimal estimation problems for nonlinear non-Gaussian state-space models do not typically admit analytic solutions. Since their introduction in 1993, particle filtering methods have become a very popular class of algorithms to solve these estimation problems numerically in an online manner, i.e. recursively as observations become available, and are now routinely used in fields as diverse as computer. The real time video surveillance using a system equipped for sensor support data is being developed to provide situational in the target of interest & also provide a safe means of video surveillance in the target place using raspberry pi
