As electrical power producers and cogeneration facilities must handle the load swings produced on the supply and demand side. Optimizing steam temperature control is one key way to improve the reliability of on boilers and heat recovery steam generators (HRSGs) caused by load swings. I caught up with Emerson’s Jeffery Williams who shared the details […]

Authors: Tom Snowden, Greg Schirm Photovoltaic power stations (or solar parks) have traditionally used PLCs as their preferred control devices. Size, ruggedness, and cost are often cited as reasons for using PLCs. With the release of the Ovation Compact Controller, Emerson is merging the scalability of PLCs with the power of the Ovation distributed control […]

The reality for manufacturers and producers is that their plant assets continually degrade over time. Valves wear over time, electrical assets may experience intermittent faults, and rotating equipment imbalances may lead quickly to forced outages. In this 3-minute YouTube video, Alert Plant Operations When Rotating Equipment Problems Pose a Threat, Emerson’s Kevin Rossi shares ways […]

Emerson’s Mircea Lupu shared his thoughts on Ovation system algorithms for handling processes with long lag times—a control challenge that vexes many. Mircea opened noting that control algorithms are at the heart of any control system to provide stable and accurate response and robustness against disturbances and process changes. Tuning these algorithms to achieve the […]
