Abstract

TIn our day-to-day life we know that how much electricity is important and necessary. For the production of electricity, power generation should be in a sufficient manner. Power station is playing the vital role to generate power by using various sources of energy and it should produce more power when compared to the earlier stages i.e., now we all are in a modern era so that new technology is essential to produce more power and the power quality is also an important factor. In this situation the researches investigates and conclude to bring a new concept named micro grid. Micro grid requires storage devices that increase the inertia and avoid instability of the system. Micro grid is designed, built and controlled by “Customers” based on the internal requirement subject to the technical economic and regulatory opportunities and constraints faced. Micro grid means distributed generators on small scale rather than centralized generation and centralized control may be through renewable energy sources. The problem nearly micro grids were not particularly reliable because only one power plant supplies all of the energy. The solution for this problem is interconnecting some systems to improve reliability. To bring an alternate solution smart grid concept originates for the generation of power. Smart grid uses new intelligent techniques and automatic control through communication. For cost reduction, rise in efficiency and reliability, energy saving etc. smart grid is advantageous than micro grid.

Abstract

The objective of this work is to determine the performance of magnetic brakes in small wind turbines for various speeds. Finally, the quality of electric power produce can be enhanced by exact control of turbine`s rotor speed given by the magnetic brakes. Findings: Simulations have done using the various controllers comprising Proportional Integral Derivative (PID) Controller, Proportional Integral Controller, Fuzzy Logic (FL) Controller and Non Linear Controller in Mat lab Simulink. A comparative study is then made for the above simulations and obtained a conclusion that PID is the best choice. Besides this, a turning is made for PID controller using bacterial Fragmentation Algorithm and the best fit results are obtained. With such a controller inserted in our system, the system can have its optimum performance even at stall conditions. Applications/Improvements: With such a controller inserted in our system, the system can have its optimum performance even at stall conditions.

Abstract

Background/Objectives: Emissions of toxic substances are the major occupational and environmental problem associated with Electric Discharge Machining (EDM) process which is the highly extensively utilized nontraditional production process whereas these emissions could lead to unfavorable health issues to the operators and possess the straight forward impact towards the environment. Emissions of aerosols and gases are influenced by the temperature in the spark location which is a function of process parameters. This work aims at the characterization of hydrocarbons generated from the EDM process, in which kerosene is used as dielectric, for varying process parameters. Methods/Statistical Analysis: The experiment was designed using Taguchi L9 orthogonal array to study the influence of parameters of process on exposure. Die electrical level, Peak current Pulse Duration and flushing pressure were the parameters of process taken into account in this research. Findings: The breathing zone concentrations of emissions were sampled for gases and aerosols and these samples are analyzed for hydrocarbons using gas chromatography mass spectrometry analysis. The analysis results are compared with the exposure limit values or threshold limit values specified by the standard agencies and appropriate control measures were suggested.

Abstract

Nanogrids are renewable energy based distribution system suitable for low power household applications. This paper focuses on DC nanogrid which is supplied by Solar photovoltaic. Nanogrids are considered building cells of a Microgrid. A survey of different types of DC to DC Boost converters used in Nanogrid is presented in this paper. The topologies of some of the configurations of Boost converter are reviewed. This paper also highlights the advantages and disadvantages of all the reviewed converters.
