In India most of the people in rural areas depend on groundwater for drinking water. Serious problems are faced in several parts of the world due to the presence of high concentration of fluoride in drinking water which causes dental and skeletal fluorosis to humans. The aim of this present investigation is to study the level of fluoride in the groundwater of some villages in Banda district of Uttar Pradesh state and its comparison with the water of bore wells, hand pump and surface water by collecting ten samples of the water from five different villages during August 2014 to February 2015. The fluoride level in the underground water of villages of Banda district was exceeding the permissible limit (>1.5 mg/L). Fluoride concentrations in the water samples vary between 0.32 mg/L to 3.5 mg/L with highest concentration in Mavai village making these village prone to dental and skeletal fluorosis. It was found that all the five villages of Banda district was under serious fluoride contamination than bore well and hand pump water which causes adverse effect like dental and skeletal fluorosis. Potable water available in schools and in public hand pumps recorded the highest fluoride concentration as compared to minimum in surface indicating need of awareness among masses about ill effects of use of fluoride contaminated water. The spatial distribution pattern of fluoride concentration varies from place to place and most of the fluoride contaminated .Removal of excess fluoride and supply of potable water is urgently required in the rural areas of Banda district.

Mobile Banking App are become a vital component of Banking. Earlier banking customers were required to travel to their bank in order to process most of their transactions; today’s customers needed convenience, security, faster transactions, and new technological services. Mobile Banking App has all these features attract new banking customers and retain existing customers. Objectives of this paper are what are the features of Mobile Banking App.?To study Benefit of Mobile Banking App for Bank and Customers, Compare Banks mobile app and Bank Web browser (Website) and what are the factors affecting usage of Mobile Banking App. For this study questionnaire is prepared and filled by the customer having smartphone and android using Bank App. Easy to open and access, Long process in website in case of login, it takes too much time and Time consuming are the major reason people using Mobile Bank App over Bank Website.

A Control Scheme for Storageless DVR Based on Characterization of Voltage Sags

Pages: 190 - 195
Voltage sag remains a serious power-quality (PQ) problem by being the most common and causing more economic losses. The dynamic voltage restorer (DVR) is a deï¬nitive solution to address the voltage-related PQ problems. Conventional topologies operate with a dc link, which makes them bulkier and costlier; it also imposes limits on the compensation capability of the DVR. Topologies with the same functionality, operating without the dc link by utilizing a direct ac–ac converter, are preferable over the conventional ones. Since no storage device is employed, these topologies require improved information on instantaneous voltages at the point of common coupling and need flexible control schemes depending on these voltages. Therefore, a control scheme for DVR topologies with an ac–ac converter, based on the characterization of voltage sags is proposed in this paper to mitigate voltage sags with phase jump. The proposed control scheme is tested on an interphase ac–ac converter topology to validate its efï¬cacy. Detailed simulations to support the same have been carried out in MATLAB, and the results are presented.

Using the sun’s energy to heat water is not a new idea. More than one hundred years ago, black painted water tanks were used as simple solar water heaters in a number of countries. Solar water heating (SWH) technology has greatly improved during the past century. Today there are more than 30 million m2 of solar collectors installed around the globe. In addition to the energy cost savings on water heating, there are several other benefits derived from using the sun’s energy to heat water. Most solar water heaters come with an additional water tank, which feeds the conventional hot water tank. In the present work a concentric tubular type solar water heater have been designed to get maximum effectiveness. It is found that temperature has increased so much as compared to uncoated pipe.

A Unified Framework for Participation of Responsive End-User Devices of Smart Grid with IMOPSO
P. Amarnath ; Prof. T. Gowri Manohar
Electrical and Electronics Engineering
Year: 2016, Volume:3, Issue : 6
Pages: 203 - 210
The paper presents a uniï¬ed control framework which allows the responsive end-user devices (REDs) such as inverter-based photovoltaic systems (PVs), plug-in hybrid electric vehicles (PHEVs), and domestic controllable loads at residential level to effectively participate in the voltage and frequency control of the smart grid. The presented control framework basically relies on extracting information from active and reactive power sensitivities at different buses. In this framework, for voltage control, two support groups namely the active support group and there active support group are dedicated to each transm–ission bus. However, for frequency control, only one active support group is deï¬ned for the entire system. The REDs used for voltage and frequency control are classiï¬ed based on their controllability degree. The idea of selecting the most effective buses is also presented to minimize the burden of communication commands. Following the detection of voltage or frequency violation in the system, the targeted buses are identiï¬ed and receive corrective control signals to accordingly change their active and/or reactive powers. To minimize the manipulated active and reactive powers, the whole process is formulated as improved multiÂobjective problem solved by the particle swarm optimization. The control procedure involves a series of commands for which the incident command system is used as a secure communication structure. In this paper an improved multi-objective particle swarm optimization algorithm (IMOPSO) is designed to efficiently solve multi-objective discrete optimization problems .In the IMOPSO, a novel similarity-based selecting scheme isused to selection of the global best solution and individual best solution for each particle, and an external set truncation strategy is used to maintain the diversity in the Pareto optimal solutions. Additionally, a local search subroutine is applied on every particle to improve the search efficiency of optimization.The IMOPSO is compared with two multi-objective particleswarm optimization algorithms proposed in the literature on several test problems, and experimental results show that the IMOPSO has good performance in multi-objective discrete optimization.

Pages: 229 - 233
With the constant development of hydropower generation and significant progress of HVDC technologies, the variable speed and operation of hydropower plant with HVDC station (unit connection) became technically and commercially feasible. This resulted in a substantial improvement in system efficiency, performance and design flexibility. Further, if the hydro power plant is connected to a DC grid, thus a DC power plant with DC Power generation and DC voltage control is formed effectively and thus a DC power plant will play an important role similar to the conventional AC power plant in an AC grid system. A DC power plant can employ either HVDC Classic station or VSC HVDC station. VSC connection also provides more managed flexibility such as decoupled AC and DC voltage controls and fast electrical emergency braking too. In this review paper, the characteristics and the control principles of the hydropower plant unit connection with HVDC station are introduced. Based on this unit connect, the DC power plant concept is proposed for integration of hydropower into DC grid. The configurations of DC power plant are presented. The advantages of DC power plant and challenges for a practical system are analyzed. It concludes that the DC power plant will have a very attractive prospect for hydropower integration and DC grid application.
