A Walkthrough of Cyber Security Topics in the Electric Power Grid

Mr. Tim Yardley

Thursday, 10:45am-12:30pm

A broad walkthrough exploring various cyber security related topics in the electric power grid. This will cover basic cyber security principles, talk about where and how they are applied in different areas, and then branch into emerging research areas and commercial product evolution in the space. Expect to learn about basic principles, common tools, and application of domain knowledge around cyber security and resiliency in the electric power grid.

Tim Yardley is the Associate Director of Technology and a Senior Researcher at the University of Illinois (U of I) Information Trust Institute (ITI). He received his B.S. in Computer Science at the U of I and the M.S. in Information Security and Assurance at Western Governors University, 2014. His primary duties are to define the strategic vision and direction for applied research in emerging technology throughout the ITI portfolio, as well as conduct research to address the institute's core mission. He also acts as the industry lead in structuring research partnerships with ITI. Mr. Yardley's research focuses on trustworthiness and resiliency in critical infrastructure, particularly with regard to cyber security in systems like the power grid and telecommunications. He is a senior lead of the Cyber Resilient Energy Delivery Consortium and a principle investigator for several industry lead collaborations, Applied Resiliency for More Trustworthy Grid Operation, Secure Policy-Based Configuration, and Collaborative Defense of Transmission and Distribution Control Devices against Cyber Attacks, which aim to bring deployable solutions to solve difficult problems facing the sector. His work on Open Phasor Gateway and the Secure Information Exchange Gateway was released as open-source products in commercially supported use today. Mr. Yardley has also been involved in openly available curriculum development associated with cyber security in critical infrastructure. Slides can be found here (pdf)

Designing and Controlling a Levitating Motor

Dr. Peter Kascak

Thursday, 10:45am-12:30pm

Rotor suspension is a critical aspect of all rotating machines. Currently this is accomplished with mechanical bearings in most rotating machines. Mechanical bearings are used in these applications because they are inexpensive and well proven. In some high-performance applications, it is desired (or required) to suspend the rotor without mechanical bearings. Reasons for this include high-speed capability, extremely low spin-loss requirements, lack of access to perform maintenance, and operation in an extreme environment. This tutorial will explore the topic of bearingless motors. Fundamentally, bearingless motors are the fusion of electric machines and magnetic bearing technology. Consequentially the tutorial will explore many aspects of magnetic bearing design and control. It will look at many different bearingless motor topologies, which have been proposed and studied, and their advantages and disadvantages. This tutorial will involve aspects of electric machine design and control and go into greater depth on the bearingless technologies developed by Dr. Kascak at NASA Glenn Research Center.
