since our electrical system consists of many interconnections .in order to have a proper transmission we need grid if we incorporate some sensors it results in smart grid .today grid system consists of all interconnection tapping points
Increased demands on the nation's electrical power systems and incidences of electricity shortages, power quality problems, rolling blackouts, electricity spiked prices have caused many customers to seek other sources for high-quality and reliable electricity. Distributed Energy Resources (DER) small-scale power generation resources located close to where the electricity is used (e.g., a house or commercial sectors), provide an alternate source of energy. DER is a faster and less expensive option for the construction of large and central power plants and also high-voltage transmission lines. They offer consumers the potential for lower cost, higher service reliability, high power quality, increased energy efficiency, and energy independence. The use of renewable distributed energy generation technologies and "green power" such as wind, photovoltaic, geothermal, biomass, or hydroelectric power can also provide a significant environmental benefit.

Smart Grid The Role of Electricity Infrastructure in Reducing Greenhouse Gas ...Gruene-it.org
Most of the world’s electricity system was built when primary energy was relatively inexpensive. Grid reliability was mainly ensured by having excess capacity in the system, with unidirectional electricity flow to consumers from centrally dispatched power plants. Investments in the electric system were made to meet increasing demand—not to change fundamentally the way the system works.
Transforming the Electricity System to Meet Future Demand and Reduce Greenhou...Gruene-it.org
Most of the world’s electricity delivery system or “grid” was built when energy was relatively inexpensive. While minor upgrades have been made to meet increasing demand, the grid still operates the way it did almost 100 years ago—energy flows over the grid from central power plants to consumers, and reliability is ensured by maintaining excess capacity.

Key Aspect for Approach of Smart Grid Design Systemijtsrd
With development of smart grid technology, power generation and distribution network acts as new brain in this field. In this technology, the network will not only get going to integrated and set communicable all over the country but its demand will be tracked by the control centers in different aspect and at high time the usage of power is going to cost higher than the actual rate with intimation given to the customer through notification via sms or email. Through this research, the designing for Smart Grids was inspected from a logical aspect, monitoring its behavioral, and physical, and must observe the optimal integration of entire system. From the conventional distribution system, we can see the designed for the control of all the constituents as observe to be autonomous with each other. Thus, centralization in control and consolidated functionality are the main challenges discover by the distribution system. To minimize these matter of concern, the term ""distribution system and its responsibilities"" came into effect by using information and communications technology ICT to power the resolution in circulating distribution system. For preparing the outline in this aspect, this paper aims to present a layout in initiating smart grid technology and responsibilities. In contrast we argue to design an interest in the field of Smart Grid.

AUTOMATIC VOLTAGE CONTROL OF TRANSFORMER USING MICROCONTROLLER AND SCADA Ajesh Jacob
AUTOMATIC VOLTAGE CONTROL OF TRANSFORMER USING MICROCONTROLLER AND SCADA
LABVIEW PROJECT FINAL YEAR EEE
ABSTRACT: A tap changer control operates to connect appropriate tap position of winding in power transformers to maintain correct voltage level in the power transmission and distribution system. Automatic tap changing can be implemented by using µC. This improved tap-changing decision and operational flexibility of this new technique make it attractive for deployment in practical power system network. This paper deals with the implementation of µC based tap changer control practically, using special purpose digital hardware as a built-in semiconductor chip or software simulation in conventional computers. Two strategies are suggested for its implementation as a software module in the paper. One is to integrate it with the supervisory system in a substation control room operating in a LAN environment. In this configuration, the parallel transformers can be controlled locally. The other is to integrate it into the SCADA (Supervisory Control and Data Acquisition) system, which allows the transformers to be monitored and controlled remotely over a wide area of power-network. The implementation of µC based tap changer control needs interfacing between the power system and the control circuitry. µC s may need to interact with people for the purpose of configuration, alarm reporting or everyday control.
A human-machine interface (HMI) is employed for this purpose. An HMI is usually linked to the SCADA system’s databases and software programs, to provide trending, diagnostic data, and management information such as scheduled maintenance procedures, logistic information, detailed schematics for a particular sensor or machine, and expert-system troubleshooting guides.
OBJECTIVES: The original system can afford the following features:
- Complete information about the plant (circuit breakers status, source of feeding, and level of the consumed power).
- Information about the operating values of the voltage, operating values of the transformers, operating values of the medium voltage, load feeders, operating values of the generators. These values will assist in getting any action to return the plant to its normal operation by minimum costs.
- Information about the quality of the system (harmonics, current, voltages, power factors, flickers, etc.). These values will be very essential in case of future correction.
- Recorded information such case voltage spikes, reducing the voltage on the medium or current interruption.
- implementation of µC based tap changer control practically, using special purpose digital hardware as a built-in semiconductor chip or software simulation in conventional computers.
Importance of Measurements in Smart GridIJERD Editor
- The need to get reliable supply, independence from fossil fuels, and capability to provide clean
energy at a fixed and lower cost, the existing power grid structure is transforming into Smart Grid. The
development of a smart energy distribution grid is a current goal of many nations. A Smart Grid should have
new capabilities such as self-healing, high reliability, energy management, and real-time pricing. This new era
of smart future grid will lead to major changes in existing technologies at generation, transmission and
distribution levels. The incorporation of renewable energy resources and distribution generators in the existing
grid will increase the complexity, optimization problems and instability of the system. This will lead to a
paradigm shift in the instrumentation and control requirements for Smart Grids for high quality, stable and
reliable electricity supply of power. The monitoring of the grid system state and stability relies on the
availability of reliable measurement of data. In this paper the measurement areas that highlight new
measurement challenges, development of the Smart Meters and the critical parameters of electric energy to be
monitored for improving the reliability of power systems has been discussed.
The energy grid is currently undergoing a historical change of state from the traditional structure where a utility owns the generation, transmission and distribution services into an integrated smart grid in a monopolistic market which introduce consumers as active players in managing and controlling the power. This report provides an analysis of the methods applicable to smart grid interoperability tests. A systematic approach for developing smart grid interoperability tests was adopted by analyzing a house and an industries looking at the analysis of their active power. This analysis of active power gives the exact idea to know the range of maximum permissible loads that can be connected to their relevant bus bars. This paper presents the change in the value of Active Power with varying load angle in context with small signal analysis using wind, solar and generator grid . The result obtained showed that, consumers can then choose the cheapest energy to be consumed.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
