    #POWERGEN 2017 Preview: Helping Power Generators Address the Skills Gap

    Author: Douglas Morris A January 2017 report from the U.S. Energy Department states: Workforce retirements are a pressing challenge. Industry hiring managers often report that lack of candidate training, experience, or technical skills are major reasons why replacement personnel can be challenging to find—especially in electric power generation. The wave of retirements has been talked about for years and...

    #POWERGEN 2017 Preview: Flexible Operations

    Author: Douglas Morris The new plants that are coming online today are already designed for fast start and flexible operations. With the changing generation mix, being able to move a unit is essential as fleets dispatch more renewables. But what about older plants that were designed to operate as baseload generation? Sometimes units must be mechanically retrofitted to be able to better participate in the market...

    #POWERGEN 2017 Preview: Microgrids and Controls

    Author: Douglas Morris Microgrids are collections of generating sources that are coupled to operate as one either connected to or disconnected from (islanded) the main power grid (sometimes called the macrogrid). Being able to independently provide one’s power is becoming popular with standalone entities like colleges or universities, military bases, and remote locations. Hawaii is embracing microgrids and has...

    Automating Combined-Cycle Power Generation Startups

    In combined cycle power plants : …the heat of the gas turbine’s exhaust is used to generate steam by passing it through a heat recovery steam generator (HRSG) with a live steam temperature between 420 and 580 °C. The condenser of the Rankine cycle is usually cooled by water from a lake, river, sea or cooling towers . Over the past decades, combined cycle power plants were built to handle base electrical...

    Industrial Internet of Things and Electric Utilities Fleet Management

    Electric utilities must carefully manage their fleet of power generation facilities to improve energy efficiency, reduce emissions, meet regulatory requirements and operate safely. Enabling Industrial Internet of Things (IIoT) technologies provide an opportunity to more effectively manage these fleets than has been possible before. Jonas Berge accepts Best Paper Award – Digitalization track at 2017 PowerGen Asia...

    #POWERGEN 2017 Preview: HRSGs, Steam Attemperation and Tube Leaks

    Author: Douglas Morris We all know that today’s plants must cycle more; that’s just the expected mode of operation. Keeping plants online with the ability to cycle, particularly cost-competitive combined cycle units, is a focus for most utilities and avoiding heat recovery steam generator (HRSG) tube failures is a good place to start. These failures can be attributed to corrosion, thermal issues, and creep...

    Successfully Addressing NERC CIP Cybersecurity Standards

    The power industry is perhaps the furthest along in hardening their cybersecurity defenses due to the work of the North American Electric Reliability Corporation (NERC) on the critical infrastructure protection (CIP) cybersecurity standards—now at version 6 . In a Power magazine article, Tackling NERC CIP and Cybersecurity at America’s Largest Gas-fired Cogeneration Plant , this electrical energy and steam energy...

    Monitoring Your Medium Voltage Switchgear

    When I worked in the offshore oil & gas business many years ago, production platforms typically had low-voltage electrical systems running motors no larger than 480VAC. Over the years as the process sophistication grew and motors with variable speed drives replaced engine-driven compressors and other assets, the need for medium voltage systems (between 1KV and 35KV) grew. For most other industries with access to an...

    Reducing Control System Hardware Footprint

    Emerson’s Ben Skal presented on reducing the Ovation distributed control system hardware footprint at the 2017 Ovation Users Group conference. Virtualization technology is at the heart of this hardware footprint reduction and having less workstation and server hardware to maintain. Ben’s presentation focused on: What is virtualization & how it works Appropriate uses of virtual machines (VMs) ...

    Take Charge of Partial Discharge to Protect Plant Assets

    Emerson’s Jonathan Murray discussed partial discharge solutions at the 2017 Ovation Users Group conference. Unplanned electrical asset failures can halt production and amount to millions of dollars of associated costs. The IEEE and NFPA organiz...
