Model predictive control in power generation was the subject of a 2017 Ovation Users Group presentation by Emerson’s Ranjit Rao. Rajit opened comparing classical control with model-based control. In classical control, a proportional-derivative-integral loop is used with feedback. There is a setpoint, the actual process variable and the error or difference between the process variable […]

At the 2017 Ovation Users Group conference, Emerson’s Bob Kerestes and Sheldon Willis gave an update embedded simulation in the Ovation system. Sheldon opened the presentation describing types of uses for simulators for training and engineering. For training simulators, simulations can range from simple tie-back models to high-fidelity models which simulate the dynamics of the […]

Generators turn mechanical energy into electrical energy by moving electrical conductors in a magnetic field. Excitation creates the electromagnetic field to make this mechanical to electrical conversion occur. Emerson’s Rich Dennis provided a basics presentation on excitation control at the 2017 Ovation User Group meeting. Excitation control includes synchronous machine regulation, exciter, synchronous machine for […]

There are many paths to pursue in improving cyber defenses for industrial control systems (ICS). At the 2017 Ovation Users Group conference, Emerson’s Tom Kizer presented on applying threat intelligence for system defense. Tom opened by acknowledging that identifying effective threat intelligence is difficult. Threat intelligence is data collected, organized, analyzed and refined about potential […]

At the 2017 Ovation Users Group conference, Emerson’s Fred Huff presented on microgrid controls. Fred opened describing a microgrid as one that could stand alone or connect to the larger electrical grid. Components include distributed generation (DG), loads—critical and non-critical, energy storage systems (ESS), points of common coupling (PCC) and a microgrid controller. Fred focused […]
