Speaker:
Eduardo Palma

Regional Technical Manager Schweitzer Engineering Labs

When: 11:30 AM – 1:30 PM, August 18, 2022

Abstract:

Cybersecurity is presently an important topic for critical control systems, as those found in Electric Power Systems. In the presentation, we will cover an introduction to Industrial Control Systems (ICS). It will define the differences between enterprise networks and ICS networks. Next, Cybersecurity’s purpose and core concepts are defined. These are used to illustrate how to start thinking like a defender against malicious attacks. An understanding of the anatomy of a Cyber Attack is key to visualizing the different vectors available to hackers, as well as defensive security strategies possible. Last, the presentation will analyze a case study: The Ukraine incident, December 2015, when the Ukrainian Power System Operators suffered a cybersecurity attack causing extensive damage.

Speaker:
Fernando Calero

Senior Principal Engineer for Schweitzer Engineering Labs

When: 11:00 AM – 12:30 PM, May 12, 2022

Abstract:

A very important aspect of the protection and control (PAC) of modern power systems is the communications system. The presentation will provide an overview of past, present, and future technologies for PAC power systems.  The presentation will address the needs for communications for PAC.  The overview of the technologies will follow from power-line carriers to packet-based communications.  While wide-area communications are important; presently substation IED communications are the hot topic.  A discussion of substation networks and technologies for PAC applications in the substation will be the focus.

April 20th, 2022

Speaker:
Kirsten Pomales Langenbrunner and Diogo Almeida

When: 12:00 PM – 1:00 PM, May 3, 2022

The IEEE Miami Section, the IEEE Blockchain Initiative, and the FIU School of Computing and Information Sciences are partnering to bring you a two-part workshop introducing students and professionals to blockchain technology, from a business and engineering perspective. These workshops are designed to be valuable for both engineers and business strategists.
IEEE Blockchain Initiative is creating a Miami local group for recurring meetups. If you are interested in becoming a member, please attend the workshop.


Blockchain: Business Applications
Kirsten Pomales Langenbrunner will be joining us for an interactive discussion on blockchain business applications across the enterprise, gaming, finance, and more. By the end of the lecture, you’ll have a better understanding of what web 3 businesses are being built today: within the context of starting a career or startup in the blockchain space.


Blockchain Engineering 101
Diogo Almeida will be lecturing on blockchain development basics. What do engineers need to know to get started building decentralized applications? How do you determine which blockchain to build on? What skill sets are most needed in Web 3? These questions and more will be answered during the discussion.

Abstract:

The improvements in MRI as a diagnostic tool in terms of image quality, speed, and clinical use have required increased capabilities and performance of the gradient amplifier. In addition, extremely high fidelity for reproducing the current command from the central system is very critical for imaging quality. Therefore, high power and high bandwidth gradient driver is needed for a high-performance MRI system. The driver output is arbitrary bidirectional currents that can be pulsating between zero and full power and must be reproduced with errors on the ppm range.

The gradient Driver is one of the key components in a magnetic resonance imaging (MRI) scanner. The driver is responsible to create gradient fields by supplying the gradient coil with a large current (>1000A) and high voltage (>2000V) to achieve a strong gradient field and fast slew rate.

The gradient driver consists of three switching power amplifiers (inverters), multiple power supplies, and high-performance digital control:

  • Switched amplifiers are implemented with cascaded H-bridges to have high ripple frequencies (>125kHz) for the required bandwidth at power levels needed. High-performance modular solution with SiC devices enables solutions with only two bridges and 99% efficiency.
  • The accuracy for the currents supplied to the gradient coils requires regulated voltages provided to the inverter with reduced voltage change (<10%). The power supplies must be designed for peak power. Capacitors for energy storage in the system limit voltage sag and peak power draw from the facility power utilities.,

The presentation will provide a description of the electronics technology and technical implementation of the amplifiers currently used on high-performance MRI systems.
