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 […]

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 […]

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 organizations identify Partial Discharge (PD), a breakdown of the assets insulation, as a leading cause of failure. Manufacturers are looking for […]

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 […]
