In order to operate aging nuclear power plant instrumentation and control systems for up to 60 more years or longer, there must be a smooth transition from existing analog technologies to advanced digital platforms. For this to occur, electromagnetic compatibility concerns related to both qualification testing and the electromagnetic environment must be addressed to ensure safe and reliable operation of these systems within the plant’s electromagnetic and radio frequency interference environment. By understanding the regulatory requirements and sharing implementation experience, digital system upgrades can be installed successfully.

CHLOR*RID International launched the Chlor*Ion Meter, a handheld digital testing device that electronically measures chloride on surfaces with an internal ion-specific electrode. Most surface chloride testing devices offer an external electrode on a cord, but these could be damaged in the field, CHLOR*RID says. Because it digitally measures chloride on surfaces, the Chlor*Ion Meter’s ion […]

Digital fieldbus technologies, including Foundation fieldbus and Profibus, are increasingly being used with success in the nuclear and fossil fuel power industries.

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.

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).

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.

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.

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.

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.

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.

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.
