3 Steps to Monitoring Critical Electrical Assets – Free White Paper

By Jonathan Murray, Director of Products – IntelliSAW, Emerson Automation Solutions

I’d like to talk about a significant issue in the power industry. Electric utilities strive to improve reliability in the face of challenges such as fewer operators, aging assets and increased cycling. An electrical power critical asset (switchgear, transformers, bus ducts, etc.) failure can result in a forced power outage leading to lost production, environmental issues, personnel safety concerns, potential litigation, and repairing and/or replacing the damaged asset. All of this can result in critical risks and millions of dollars of associated costs.

The following table shows a simple view of the associated average potential revenue lost if a 500MW generator was down due to a forced outage.

 

 

To address these issues, asset maintenance is transitioning from traditional reactive and time-based activities to implementing a proactive strategy through continuous condition-based monitoring. Modern sensing technology makes it possible to continuously monitor the health of electrical power critical assets and inform plant personnel when, or even before, problems arise.

I’d like to offer you a white paper that describes the three steps for deploying condition-based monitoring on critical electrical power assets which will lead to a proactive – and eventually, predictive – maintenance strategy:

  1. Prioritize which assets should be monitored.
    Independent of the type of power plant, a typical electrical power delivery system includes assets such as generators, generator circuit breakers (GCBs), line disconnect switches, step-up and step-down transformers, segregated and non-segregated bus ducts, potential transformer cabinets, medium voltage switchgear, motors, and other equipment needed to support the transmission and distribution of power. Prioritizing which assets to monitor is key to success.
  1. Apply continuous condition-based monitoring.
    The 3 most common electrical asset failure modes include thermal breakdown, insulation breakdown, and air dielectric breakdown. Although manual inspections can be used to monitor less critical assets, continuous condition-based monitoring is the preferred alternative for assets which must be kept online at all times. Continuous condition-based monitoring systems are available with temperature, partial discharge (PD) and humidity-sensing capabilities.
  1. Analyze data and evaluate asset health.
    Once data is acquired and brought into a digital space where it can be analyzed, limits and alarms can be placed on data trends. This allows the delivery of actionable information to the maintenance and engineering team responsible for the assets.

The white paper will help you select the best monitoring and analysis approaches for your requirements. Please click HERE for your copy. And if you have any questions, please contact me at Jonathan.Murray@Emerson.com.

Rosemount Analytical Presentations at Emerson Exchange Stuttgart Highlight Advances for Users in Oil and Gas, Power and Utilities, and Alternative Fuels

We’d like to tempt you with a trip to Stuttgart! You’re aware of the dynamic interaction of Emerson Exchange, and that this 2014 event for Europe, the Middle East and Africa will be held April 1-3, 2014 in Stuttgart, Germany, right? were you aware that the event features more than 130 presentations, mostly from users, on real life case histories from 25 countries and a wide range of industries. You’ll find many things of significance to you at Emerson Exchange, and if you register before March 7th, you save up to 200 Euro off the fee. (Of course, if you’re not lucky enough to go to this event, you can share in many of the findings through Emerson Exchange 365).

The 2014 Conference Presentation Tracks include: Operate Safely & Legally, Maintenance, Reliability & Asset Optimisation, Energy Management, Process Optimisation, Business Management & Information Security, Instrumentation Applications, Valve Applications, Wireless Applications, Project Excellence and Control System Applications & Migrations. The in-depth Industry Forums cover Chemical, Engineering, Life Sciences, Oil & Gas, Power, Refining and Petrochemical, while the “Meet the Experts” sessions give you the chance to ask questions specific to your operations and challenges. There’s even a networking event at the Porsche Museum.

When you attend, watch for these exciting sessions from Rosemount Analytical –

  • In-Line Analysis of LNG Improves Quality & Throughput
    By replacing lab measurements with in-line Gas Chromatographs, Lukoil has been able to improve process optimization. This, in turn, led to higher output and conformance with product quality requirements.
  • Instrumentation for Enhanced Fuel Flexibility of a 400 MW Natural Gas Fired Turbine with Ultra Low NOx Emissions
    ALSTOM is a provider of turn-key power generation solutions. The compact GT24 and GT26 sequential combustion gas turbines are developed to face current challenges in the power industry: shifting consumption trends, more stringent emission legislation and flexibility in fuel gas composition. In combined-cycle applications, the GT24/GT26 is capable of net plant efficiencies close to 60% with low NOx emissions across a wide load range. ALSTOM gas turbines are proven to operate reliably at high and rapidly changing C2+ concentrations. A key success factor is the validation and integration of a continuous, fast and accurate C2+ concentration measurement system into the engine protection and control concept.
  • Gas Chromatography Advantage in Cool Down & Gassing Up Operations for LNG Import/Export Terminals
    Reganosa LNG terminal is the leading terminal in Spain in gassing up and cooling down operations for LNG tankers since 2010 when this type of Services started to be systematically requested in the Spanish Gas System.The point of the operations remains in controlling the precise time the vessel is ready to advance in the operation phase from gassing up to cooling down and here a flexible Chromatography system is needed as BOG (Boil Off Gas) as LNG phases have to be surveyed continuously.

    Reganosa has used the available equipment for a standard LNG import terminal and with the support of Emerson adapted it for export activity, turning it into a unique tool to achieve our clients’ satisfaction.

We look forward to seeing you at Emerson Exchange and Emerson Exchange 365!

Wireless SWAS System Models Selection Criteria for All Industrial Plants

Snehal Shah here for this week’s blog post. As you may know, steam and water analysis systems in power plants present challenges common to many industrial plants in harsh environments. Finding a cost-effective way to predict maintenance requirements without excessive personnel time was one of the requirements when a Power Plant in India set out to select an analysis system for two new power plants. Their choice was Emerson and their system is wireless. Why did they choose wireless and why should you consider wireless?

The total system includes fifty-six Model 1056HT analyzers each using the Smart wireless THUM adapter to provide a highly flexible, self-organizing network. In addition, the Indian Power Plant is using four units each of the Rosemount CFA Silica and Sodium analyzers and four sample conditioning systems. The Power Plant in India chose the Model 1056 because all the units were panel-mounted and by using the Model 1056, the wet chemistry units in the system could also be configured for wireless signal transmission.

While we often think of wireless as a way to save wiring and installation costs in an existing industrial facility, in fact, this project clearly shows that there are other drivers for the choice of wireless. The wireless plants are brand new Green Field projects and the cost of installing a wired system was not the primary factor in the selection of Emerson. Rather it was the quick commissioning made possible by wireless. The time savings involved will allow for early project completion. If you have any questions about how wireless can work for you, please do let us know! We’d be happy to provide you with answers.

Another reason for selection of the wireless technology for the SWAS was the ability to get vital diagnostics from all the measurement points. Analyzer diagnostics such as pH cracked glass are important to maintenance scheduling. Temperature is always measured in the pH, conductivity and DO analysis but typically it is not used in wired systems because it consumes analog input at the DCS. Using wireless, this Power Plant customer in India is able to get sample temperature as required – a significant indicator of the “health” of the sample conditioning system.

Emerson has pioneered wireless steam and water analysis systems for the power industry. With this Indian Power Plant customer, the application clearly demonstrates that there are many important reasons to consider wireless technology in industrial plants of all types. Let us know if you’re considering wireless. We’d be happy to answer any questions you might have.
