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) ...

Model Predictive Control in Power Generation

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 and setpoint. Based on the...

Simulation for Training and Engineering Applications

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 running process. For high-fidelity...

Generator Excitation 101

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...

Suite of Cybersecurity Technologies and Practices

Emerson’s Adam Boeckmann presented the Power and Water Cybersecurity Suite at the 2017 Ovation Users Group conference. He opened describing the team that formed over the last several years that now supports more than 200 sites in the U.S. alone. He shared the story of the recent Wannacry/WannaCrypt ransomware cyber-attack. In March of 2017, Microsoft released a patch. A month later, the National Security Agency...

Applying Threat Intelligence for Industrial Control System Defense

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 or current attacks...

Microgrid Monitoring and Control

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 on the control components...
