    Blog: Vortex Flow Meters in Safety Instrumented Functions

    Safety instrumented systems provide a layer of protection beyond the control system to safely shutdown the process during abnormal situations. A safety instrumented function (SIF) or “safety loop” includes the sensing device, logic solver and final control element to perform safety function upon demand. Flow measurement devices are often the sensing devices in these SIFs. Some flow measurement technologies...

    DeltaV Blog: Getting Alarms Right the First Time or Fixing Later

    As distributed control systems, human-machine interface (HMI)-based control systems and safety instrumented systems came along, adding alarms was easy and close to free. The problem they introduced was too many too often—whether immediate action was warranted or not. The ISA 18.2 alarm management standard was developed to help manufacturers and producers optimize the alarms to minimize alarm flooding conditions and provide...

    Blog: #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...

    Blog: #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...

    Blog: #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...

    Blog: 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...
