Yokogawa Electric Corporation has announced the development of Release 5 of the Centum VP integrated production control system, the company’s flagship product and a cornerstone of the VigilantPlant concept that aims to help customers realize the ideal plant. Developed with the aim of bringing companies operational excellence through the use of field digital technology, this latest version of Centum VP will be released to the market this August.

Yokogawa began developing field digital technology with its Foundation fieldbus compliant products, which reduce the need for field wiring, allow the introduction of intelligent field devices, and improve the management and diagnosis of digital field devices, playing an essential role in optimizing plant operations.

But advances in field digital technology have led to drastic increases in the volume and variety of field data, and Yokogawa’s customers are now seeking to make better use of this resource. Control systems must be capable of handling a massive amount of field data at comfortable speeds.

Yokogawa has developed a new field control station (FCS) that can fully satisfy such needs in the field digital era. Centum VP Release 5 will assist in improving the use of plant information and reducing lifecycle costs with simplified engineering. It will also enable unified plant operations by integrating with many other systems.

The new release features:

1. New field control station (FCS) with industry leading performance

In comparison with Yokogawa’s previous FCS, the new FCS will feature four times the processing performance, twice the application storage capacity, and five times the control network throughput.

2. Unified gateway station (UGS) for better system integration

Centum VP Release 5 will also include a unified gateway station (UGS) that improves integration with other systems, allowing Centum VP to control and monitor all the systems at plants, including PLC systems. Despite the differences, all of their operation windows will have the same Centum VP “look and feel”.

The UGS makes possible the integrated control and monitoring of an entire system comprised of both central large-scale facilities and remote facilities via the CentumVP human machine interface.

3. Enhanced alarm management based on ISA18.2 Standard

CAMS for HIS Yokogawa’s Consolidated Alarm Management Software for Human Interface Station (CAMS for HIS) includes new functions to manage change process specified in the ISA18.2 standard’s alarm management lifecycle model.

4. Windows 7 and Windows Server 2008 R2 support

Support for Microsoft’s latest 64-bit Windows 7 and Windows Server 2008 R2 operating systems will be included for customers.

Evaluation of electromagnetic field measurements

Narda Safety Test Solutions now offers a remote control, analysis and management software package for the frequency-selective field measuring set SRM-3006. The SRM-3006 TS PC software simplifies the acquisition and storage of results of electromagnetic field measurements, enables analysis and automatic generation of user-specific reports.

Large quantities of data often result from electromagnetic radiation measurements designed to protect people or the environment. Data acquired by the Selective Radiation Meter SRM-3006 from Narda Safety Test Solutions can now be managed, analyzed and recorded using the PC software SRM 3006 TS.

Database functions facilitate storage by measurement location and measurement project. A separate data field contains extra information about the measurement location and conditions, such as GPS data, cartographic representations or voice comments recorded on-site.

All results can be subsequently analyzed. For example, the software can automatically search for peak values in frequency spectra or determine average values over time periods. Integration over a selectable frequency range enables automatic determination of the field exposure due to radio communication service. Similarly, later analysis enables identification of pilot channels.

Control Techniques’ Commander SK AC drive gets conformal coating

Control Techniques’ versatile Commander SK AC drive range will now be given a conformal coating to enhance its protection for environments where an extra level of robustness is required.

The conformal coating will enhance protection, when the drive is installed in an appropriate enclosure for the environment, giving extra protection against moisture, dust and chemical ingress and temperature extremes, enhancing product life and preventing or delaying electronic failure. Coating of the drives will start with the smaller sizes (to 7.5kW) in September and be extending across the whole range by October this year.

The Commander SK range, which spans 0.25 to 132 kW, is designed to provide cost-effective AC motor speed control and delivers performance with simplicity and ease of use. With the parameters needed for 90 per cent of applications printed on the front of the drive, Commander SK ensures installation is straightforward.

Commander SK’s compact footprint saves panel space and money, too, is saved by eliminating additional components such as EMC filters. The onboard PLC removes need for an external PLC and power supplies. Integrated fieldbus options minimize need for external I/O to interface with the drive.

Portable machine tools speed up bore plug removal

Thanks to their power and versatility, heavy-duty portable machine tools are revolutionizing the way plant repair and maintenance projects are done, claims Climax Portable Machine Tools.

Korea Plant Service & Engineering (KPS&E) – which specializes in maintenance of power generation facilities such as hydro-thermal, nuclear and renewable energy plants – worked with Climax Portable Machine Tools on a simpler, safer and more efficient method to remove a turbine bore plug at a plant in Korea that shaved five hours from a project that would take a full day.

The project required removal of a shrink-fit 300 mm diameter bore plug in the rotor assembly so that the journal shaft could be inspected for signs of stress and corrosion. A routine method for removing the bore plug is by using a conventional magnetic drill to produce connecting holes in the plug, eventually dividing the plug into four. Then a hammer and pipe or rod are used to chisel and loosen the plug and remove it.

This method is time-consuming and costly in labour and downtime, says Climax Portable Machine Tools, and can also be dangerous for the machinist or damage the rotor.

KPS&E and Climax Portable Machine Tools has devised a simpler method for removing the bore plug that involved using two heavy-duty portable machine tools and renting a drill kit accessory from I.W.S. Limited, Climax’s distributor in Korea.

KPS&E’s machinists used a standard Climax BB5000 boring machine onto which they attached a drill kit, converting it into a spade drill. A single hole was then drilled in the plug and the machinists replaced the boring machine with a Climax BW1000 AutoBoreWelder, which put a single pass weld bead inside the plug. Once the weld cooled the machinist easily slid the remaining plug out. This project took only two hours, largely because drilling time was greatly reduced by using the portable boring and drilling machine.

GE launches Cryodisc service safety value

To help power plant operators curb emissions and reduce maintenance costs, GE has released the Consolidated 1900 Series Universal Media Cryodisc safety valve option.

Patented Cryodisc technology, which deflects toward the nozzle to create a tighter seal than other technologies when exposed to isolated colder spots, helps reduce leakage of cryogenic fluids and correct small leak paths, said GE.

The safety valve option uses a unique disc geometry that is specifically geared towards the cryogenic application of leakage solutions. The Cryodisc diminishes the amount of process fluid lost during a valve leakage and ultimately helps to reduces the potential need for intervention by a company’s maintenance personnel.

“The safety valve option was developed specifically to address the lost hours and reduced plant productivity during a valve leakage,” said Nathan Brunell, marketing and product leader for GE Energy. “While other companies do offer safety relief valve options, the Cryodisc is designed with cryogenic technology in mind as an efficient solution to leaking valves. The geometry of the Cryodisc allows customers to reduce plant downtime when leaks occur.”

In addition to reducing the leakage of cryogenic fluids, the Cryodisc self-corrects and closes small leak paths due to its disc geometry. The result is typically increased plant efficiency for customers and a decrease in the need for costly and time consuming compensatory behaviors, such as the physical de-icing of valves.

Power quality analyzer features identify problems

Outram Research Limited – a specialist manufacturer of leading-edge power quality analysers – announces that the PM7000 now offers additional features to help identify and resolve power quality problems caused by the increasing use of energy-efficient appliances and renewable power sources.

Harmonic distortion can become a significant problem, as more and more mains-connected devices use high-efficiency switching power supplies or inverter-type power sources and power is increasingly supplied from renewable sources that require a DC to AC conversion.

The Outram Ranger PM7000 is the first power quality analyzer to offer analysis of the phase difference between the harmonic voltage and current, giving additional detailed information about the source of distortion of the mains waveform, according to its maker. Modern switching power supplies can problems at high frequencies, so the PM7000 offers one of the industry’s highest sampling rates, recording up to the 50th or 120th harmonic.

“Visibility is critical when solving the increasing problem of harmonic distortion of the mains waveform,” said John Outram, managing director of Outram Research. “By providing information on the phase difference between current and voltage up to the 120th harmonic we help engineers identify and resolve problems quickly and efficiently.”

The new harmonic distortion analysis features are now provided as standard across the Outram Ranger PM7000 power analysers.

SPX launches DSCV-SA valve

The DSCV-SA valve from SPX is designed for unprecedented reliability, protecting both power plant boilers and steam system equipment and eliminating operational risks during plant start-up, shutdown and turbine trips.

The features technical innovations developed following extensive consultation with customers in the power generation sector, said SPX.

Unlike conventional turbine by-pass valves, the DSCV-SA is designed to use high-pressure balancing rather than low-pressure balancing. This eliminates risk of wear, damage or breakage relating to piston rings and balancing systems, which are a problem with traditional valves.

Another key innovation is the introduction of cooling water through steam atomization to significantly accelerate the evaporation and desuperheating process.

Also beneficial is the substantially increased surface area of the finely atomized water droplets, which helps to promote rapid heat transfer.

In addition, the atomised, pre-heated water is introduced directly into the centre of the steam flow, negating the need for thermal liners and eliminating dependency on the main steam velocity. This makes the DSCV-SA unrivalled for turndown.

“This is the only valve completely designed for the peak loading required by today’s power generation market. We have designed out the risks associated with traditional solutions,” said Mark Wheat, business unit manager for SPX’s Copes-Vulcan product line.

Hundreds of DSCV-SAs are used worldwide in fossil and solar fired power generation plants along with continuous operation steam let-down stations in many industrial activities that are known to rely on steam generation.

“To date we have had very positive feedback from satisfied customers” said Wheat.

Proximity probe offers rear and side view target protection

Condition monitoring specialists Sensonics have added a new option to their established range of proximity probes which virtually eliminates the detrimental effects on measurements caused by both side and rear targets, said the company.

The PRSVBeam proximity probe has an innovative tip design which overcomes problems associated with traditional probe designs, such as poor accuracy, system non-linearities and extended set-up time. In certain monitoring applications, for example where the probe tip is installed close to the machine casing or in a counter bore where the side view can distort readings, the effectiveness of proximity probes can be compromised. While the probe face can be fixed opposite the main target, it is likely additional side and rear targets will also impact the measurement and this situation worsens as the designated target moves away from the probe face, hence system non-linearities and extended set-up time.

Proximity probes operate on the principle of eddy currents set up in the surface of a conductive target material perpendicular to the axis of the probe tip. Proximity to the target affects the eddy current magnitude and field strength which is detected through a probe driver as a linearised distance from the probe face. Traditional probe tip designs are exposed to the target and side and rear views.

The new PRSVBeam offers a fully protected rear and side view through complete metallic encapsulation of the probe sensor assembly and its tip design provides a beam effect towards the target resulting in excellent linearity, even if fitted with the tip flush to the machine case. At the extreme end of the probe range the effect is a 0.5 per cent measurement error which reduces to less than 0.2 per cent. Another benefit of this tip design is that it withstands pressures up to 300 bar and to provide sensor tip protection with heavy particle based fluids.

The introduction of this new probe option provides a measurement range spanning 0.2 mm and 1.7 mm and linear within 1 per cent in a 10 mm diameter tip probe, providing micrometre resolution for both critical fluid film bearing vibration and shaft position applications.

New addition to 3010 miniFID range introduced

The Signal Group has launch the latest version of the popular 3010 miniFID range: the miniFID Pure.

The 3010 miniFID portable FID (flame ionization detector) has full MCERT accreditation and is simple and easy to use in awkward areas, according to its maker.

The miniFID Pure adds a new dimension to the product range with a built-in heated catalyst to improve sensitivity and stability. Compliant with the new draft EN12619, the miniFID Pure also has optional full data-logging on-board with easy to use software USB interconnectivity.

“Our 3000 series of hydrocarbon analysers have always been regarded as the top end of the market,” said John Clements, the Signal Group’s managing director. “Thorough and extensive tests carried out by the UK NPL and AEA laboratories have verified this status and we are now concentrating on yet more developments of this product to further enhance its usability.”

Signal Group is the largest UK manufacturer of source emissions test equipment. It provides a wide range of components for every kind of industry and application.

MHI develops cargo container energy storage unit

Mitsubishi Heavy Industries Limited (MHI) has developed Japan’s first cargo container-type large-capacity energy storage system that uses a lithium-ion rechargeable battery. The system is capable of providing power of up to 1 MW and its mobility makes the system suitable for a wide range of applications, including emergency use. The actual system has been installed at the Nagasaki Shipyard & Machinery Works of MHI in Nagasaki Prefecture, Japan, and began verification testing for a power stabilization system application from early last month towards the commercialization of the system.

The container-type ‘megawatt-class large-capacity energy storage system (ESS)’ consists of a 40 ft long container unit, which houses 2,000 units of lithium-ion rechargeable batteries, and a 20ft-long container unit, in which two power conditioners are installed. Power conditioners are used for DC and AC conversion and their input/output control. The system has the capacity to store 408 kWh and is designed to have a 90 per cent system efficiency.

The power storage system is capable of providing electricity for some 100 households for three- to eight-hours. By using multiple units of the system, power output is increased to tens of thousands of kW.

The system installed for verification testing in Nagasaki is currently being adjusted towards an in-plant electric-load leveling test. Testing will be conducted envisaging such cases as short-cycle conditioning to level fluctuations of electricity generated and medium- and long-cycle conditioning for a period of several hours.

Parker extends icount range

Parker Hannifin has enhanced its range of icount online particle and moisture detectors with the introduction of an innovative new self contained and portable device for measuring the quality and cleanliness of hydraulic oils and hydrocarbon fuels.

The icountOS (Oil Sampler) incorporates a laser detection particle counter, battery and pump into a single integrated unit for the real time condition monitoring of fluids, thereby helping maintenance engineers to maximize productivity and extend system life.

Launched as part of an ongoing programme for developing the icount family that will create a full range of products for all potential fixed and static applications, the icountOS provides a compact, simple to set up and easy to use solution for providing an immediate warning of particle and moisture contamination in fluids, allowing remedial action to be taken quickly before system degradation or failure occurs. Available in three versions, for monitoring the quality of hydrocarbon fuels, and either offline or inline oil sampling, the new system is built to ISO standards and uses proven Parker laser particle detection to produce extremely accurate and repeatable results.

Similarly to other icount products, such as the Oilcheck and icountPDR, the icountOS is lightweight, yet robust and fully protected by a tough plastic case, making it ideal for use in a wide range of industrial and mobile applications. There is also an optional pressure reduction attachment for online use, which can reduce the pressure of the process line. The icountOS has a minimum sample time of three seconds and can be used at flow rates from 10-160 ml/min and at line pressures from 2-420 bar.
