ElectricalWorld - Incorporating Electrical Engineer

Fairchild has launched the world’s first 1000V integrated power switch, offering what it claims is the industry’s highest breakdown voltage in a single package for designing highly reliable switching mode power supplies for smart meter, appliance and industrial systems. The new FSL4110LR switch eliminates the need for external components found in competing solutions, enabling power designers to easily meet their time to market and reduce bill of materials. The company claims: “Fairchild’s new power switch is the only solution of its kind that provides Abnormal Over Current Protection (AOCP), which protects the power converter from transformer abnormalities and is particularly important for smart metering applications” The FSL4110LR integrates a VDMOS SenseFET (BVDSS=1000V) with built in line compensation for wide input voltage range from 45Vac to 460Vac. It also includes built-in input over voltage protection and a safe auto-restart mode for all protection conditions. Fairchild is exhibiting at Electronica 2014 in Munich, Germany from November 11 to 14 in Booth A4.506. “Fairchild’s new power switch is the only solution of its kind that provides Abnormal Over Current Protection (AOCP), which protects the power converter from transformer abnormalities and is particularly important for smart metering applications,” Gaurang Shah, Sr. VP, power systems business group at Fairchild said. “With the world’s highest breakdown voltage, the FSL4110LR is an excellent solution for any designer implementing flyback converters that need to meet three phase input voltage or unstable single phase input voltage requirements.”


Comparison of PWM snd SVM based active filters

Abstract ~ The aim of this project is to simulate VSI and CSI based active power filters to Non-linear load for improving power quality. THD is used as measuring index for comparing performances of these filters. These filters can reduce harmonic in supply current. View here
Utility requirements document for small modular reactors
The Utility Requirements Document is a declaration of owner/operator requirements for new nuclear plants, large or small. More than 1200 specific changes were made in the revision to accommodate SMR designs, ranging from emergency planning and human factors design to detailed technical modifications associated with safety systems and building arrangement. Notably, the EPRI Utility Requirements Document can be used throughout a nuclear power plant project’s lifetime ~ before, during, and after technology selection ~ to support successful project execution.

Wind power a needless extra cost
The Chinese Experimental Fast Reactor (CEFR) was brought to full power at 5.00pm on December 15 and operated at this level continuously for three full days, CNNC said yesterday. The sodium-cooled, pool-type fast reactor was constructed with Russian assistance at the China Institute of Atomic Energy (CIEA), near Beijing, which undertakes fundamental research on nuclear science and technology. The reactor has a thermal capacity of 65MW and can produce 20MW in electrical power. The CEFR was built by Russia’s OKBM Afrikantov in collaboration with OKB Gidropress, NIKIET and Kurchatov Institute. World Nuclear News/a>

Spin-off to better manage the business
On: 01-12-2014 Topic: General

E.ON will focus on renewables, distribution networks, and customer solutions and combine its conventional generation, global energy trading, and exploration and production businesses in an independent company.

The new company will be spun off to E.ON SE shareholder and listed next years.

“I’m pleased that the supervisory board unanimously approved the board of management’s proposed new strategy, which will give our employees and our investors clear prospects in two strong companies that are viable for the future,” E.ON chairman Werner Wenning (pictured) said about the decision.

“We are convinced it’s necessary to respond to dramatically altered global energy markets, technical innovation and more diverse customer expectations with a bold new beginning.

“E.ON’s existing broad business model can no longer properly address these new challenges.

“Therefore, we want to set up our business significantly different.

“E.ON will tap the growth potential created by the transformation of the energy world.

“Alongside it we’re going to create a solid, independent company that will safeguard security of supply for the transformation.

E.ON SE CEO Johannes Teyssen said: “These two missions are so fundamentally different that two separate, distinctly focused companies offer the best prospects for the future,”

The company claims both E.ON and the new company will be solidly financed, be positioned to secure jobs and have prospects for creating new jobs in the future.

“We firmly believe that creating two independent companies, each with a distinct profile and mission, is the best way to secure our employees’ jobs,” Teyssen said.

“Our new strategy therefore isn’t a job-cutting program.

E.ON SE will focus on the new energy world and customer businesses.

It will have three core businesses: renewables, distribution networks, and customer solutions.

The company claims these businesses fit together and reinforce each other, creating a business portfolio with stable earnings and strong growth potential.

About 40,000 employees will be assigned to the distinctly focused company, which, by concentrating on customers’ future needs, will ensure employees have good development opportunities in a multinational energy corporation.

In its new setup E.ON will provide “innovative solutions” to meet the needs of its 33m customers.

It will take new approaches to further developing each of its three core businesses.

For this purpose E.ON will increase its investments already for the next year by about €0.5bln compared to the previously planned 2015 capex of €4.3bln.

E.ON will place a particular emphasis on expanding its wind business in Europe and in other selected target markets.

It will also strengthen its solar business.

It will upgrade its energy distribution networks in its European markets and also in Turkey and make them smarter so customers can take advantage of new products and services in areas like energy efficiency and distributed generation.

“Thanks to numerous initiatives and competitive products and services, E.ON has substantially enhanced customer satisfaction in its core markets,” the press release stated.

“The current year is the first in some time in which E.ON has enlarged its customer base in Germany.

“Through co-investments, E.ON already partners with European and American start-ups that are developing promising energy solutions that incorporate technologies of the future.

“The transformation of the energy system will continue to require reliable backup capacity well into the future as well as access to global markets for energy products,” Teyssen said.

“With a portfolio consisting of conventional power generation, global energy trading, and exploration and production, the new company will focus precisely on meeting these needs.”He added the new company’s clear focus will put it in an “excellent position to lead the necessary consolidation of power generation in Europe and to offer attractive services for the system needs of the future”.

The new company, which will have its headquarters in Germany’s Rhine-Ruhr region and offer good prospects to about 20,000 employees, “will create a better platform for securing jobs in an altered market environment.”

E.ON has agreed to sell an 80% interest in a portfolio of two wind farms in the US to Enbridge. The agreed enterprise value for the portfolio is around $650m. The 203MW Magic Valley 1 wind farm located near Harligen, Texas and the 202MW Wildcat 1 wind farm near Elwood, Indiana are operational and came into service in 2012. The two wind farms are located in areas with favorable wind regimes. The deal is consistent with E.ON’s ‘build and sell’ strategic approach. E.ON will retain a 20% interest and remain the operator of the wind farms. E.ON operates over 2700MW of renewable capacity in the US.

Abigail Ross Hopper (pictured), director of the Maryland Energy Administration, has been named director of the US Bureau of Ocean Energy Management, Interior Secretary Sally Jewell said in a statement Thursday. Hopper will assume her new position January 5, taking over for acting director Walter Cruickshank, who replaced former BOEM director Tommy Beaudreau, who is now Jewell's chief of staff. Hopper’s appointment was initially met by some trepidation from the oil and gas industry and at least one industry-friendly lawmaker who criticised her lack of experience with the fossil fuel industry. Randall Luthi, president of the National Ocean Industries Association, said his group was “concerned” that Jewell did not name a new director “with a broader range of all-of-the-above energy experience.”
