Laser Alignment of Steam and Gas Turbines
LUDECA’s new CENTRALIGN ULTRA was specifically developed for the alignment of steam and gas turbines. The system precisely aligns internal elements with upper halves for distances up to 133 feet. Accurate bore measurements can be acquired and wirelessly transmitted without interrupting other processes, saving time over traditional methods like piano wires, micrometers, and optical instruments.

The Value of a Knowledge-Based Culture Grows in Lean Times
Given delays and cancellations of new generating capacity, pushing the existing power generation fleet is more important than ever. At ELECTRIC POWER 2009, multiple presentations explored the premise that an active knowledge management strategy — requiring a blend of digital and human elements unique to each power plant — will help you extract the most productivity from your assets.

AC Power Sources for Submerged Arc Welding
ESAB Welding & Cutting Products launched the TAF 801/1251 square wave AC power sources for submerged arc welding. The power sources, designed to be used with the fully digital PEK controller, convert the secondary voltage from a sinus wave — via a thyristor-controlled rectifier bridge — to a square wave arc voltage with excellent arc […]

Plant Efficiency: Begin with the Right Definitions
The race is on to claim the title of "most efficient coal-fired power plant" on the planet. However, it’s tricky identifying finalists because of the widespread misuse of the term "efficiency" and all those nagging assumptions. Let’s first establish clear definitions and then identify the title contenders.

AREVA Makes Debut in Renewables with German Offshore Turbines
The first six of a dozen high-capacity turbines were commissioned in mid-December at the 60-MW Alpha Ventus project in the North Sea, Germany’s first offshore wind park. All 12 turbines of the €250 million project are already standing, put up in just seven months by a consortium of EWE, E.ON, and Vattenfall — formally known as Deutsche Offshore Testfeld und Infrastruktur (DOTI).

Widespread Voltage Collapse Demonstrates the Importance of Generator Acceptance Testing
A September 2005 power outage that affected two million people in the California Southland was initiated when workers cut live electrical wires after consulting erroneous design drawings, but it was exacerbated by a number of extant problems with local generation and protection configurations.

Low-Cost Wireless Sensors Can Improve Monitoring in Fossil-Fueled Power Plants
As equipment ages in fossil-fueled power plants, component wear leading to machinery failure increases as a result. Extending equipment life requires increased attention to maintenance, and one way to improve maintenance planning is to detect faults prior to failure so maintenance can be scheduled at the most cost-effective, opportune time. This type of strategy benefits from the use of additional sensors, and wireless ones can often be installed with the least time and cost.

Of Floating Power Barges and Ships
More than 60 floating power stations are in operation around the world, deploying some 4 GW at continental shores where electricity is most needed. Though these feature a variety of power sources (including nuclear, gas, and heavy fuels), most are power barges — they do not have their own propulsion systems and would have to be towed to desired locations.

How to Avoid Alarm Overload with Centralized Alarm Management
In 1999, the Engineering Equipment and Materials Users’ Association (EEMUA) released its general guide to the design, management, and procurement of alarm systems for industrial plants. The guidance document (EEMUA 191), however, is vague about applications to specific facilities, such as electric power plants. This article specifies EEMUA 191 standards and practices applicable to the electric power industry and spells out specific variations in alarming practices that are tailored for today’s power plants.

The Age of the 800-kV HVDC
High-voltage direct current transmission (HVDC) has come a long way since 1882 when the first of its type carried power from Miesbach in Bavaria to an electricity exhibition in Munich, 57 kilometers (km) away, at a mere 1,400 V. Last December, just before the world ushered in the new decade, Siemens Energy and grid operator China Southern Power Grid put into operation the first pole of a transmission link between the southern Chinese provinces of Yunnan and Guangdong, a 1,418-km ultra-high-voltage direct current (UHVDC) system. That line has a transmission capacity of 5 GW, and it operates at a voltage of 800 kilovolts (kV) — a world record.

Nontechnical Issues Affecting Digital Upgrades at Nuclear Power Plants
Existing nuclear power plants are increasingly facing the conversion to digital instrumentation and controls technology. Meanwhile, new nuclear designs have digital technology integrated throughout the plant. Digital controls will soon be inevitable, so how do we make the transition as smooth as possible? Without losing focus on the technical solutions, organizations have to pay attention to the nontechnical issues as well.

How to Get Heard in a Crowded Green World
With everything from baby food to SUVs (hybrids of course!) competing for “green mindshare,” audiences are inundated with a barrage of green claims. Although environmental awareness is at an all-time high, a growing sense of skepticism has crept into the conversation. Whereas even a couple of years ago audiences eagerly gobbled up green claims, people today are more uncertain and retain a higher degree of doubt when confronted with messages of sustainability and environmental stewardship.

Energy-from-Waste is a Win-Win for People and the Environment
Instead of just forgetting about their trash when they leave it at the curb, people increasingly are recognizing that municipal solid waste is a valuable resource. For more than 25 years, Covanta Energy has viewed waste as an important resource not to be thrown away. Waste materials have a tremendous amount of potential energy. Waste materials in landfills release significant amounts of methane, a potent greenhouse gas. Recycling and Energy-from-Waste (EfW) together, as part of an integrated waste management approach, make the best use of this resource, reducing our greenhouse gas emissions while turning waste into steam to heat our homes and businesses and electricity to power our cities and towns.

The Volvo Group and Sustainable Mobility
Efficient transport plays a crucial role in the development of society and its economy and, in many respects, commercial transport solutions are the lifeblood of the economy. At the same time, transportation has a negative impact on society, not least in the form of emissions and congestion. "The key is to strengthen the positive aspects of the transport system while working to combat the negative ones," says Stefan Lorentzson, President of Volvo Group North America.
