Abstract

Growing use of DC systems, power-electronics-driven systems, and increasing power density are introducing new dielectric challenges. Our research team at the High Voltage and Dielectrics Lab (HVDL) at Mississippi State University focuses on understanding and addressing the dielectric challenges emerging with technological advancements. In this seminar, I will introduce the ongoing research activities at HVDL that are relevant to the emerging dielectric challenges. These research topics include DC partial discharge characterization, lighting resistant composite materials, modeling of dielectric media, surface flashover characterization, nonlinear resistive field grading materials for power electronics modules, and plasma dielectric surface treatment.

Bio of Dr. Chanyeop Park

Dr. Chanyeop Park is an Assistant Professor at Mississippi State University (MSU). He received his Ph.D. degree in Electrical and Computer Engineering from Georgia Tech in 2018. His Ph.D. research was focused on improving the dielectric properties of cryogenic gas media for high-temperature superconducting (HTS) power applications. Before joining MSU in 2019, he was a postdoctoral fellow at Georgia Tech and worked closely with the Center for Advanced Power System at Florida State University. During this time, Dr. Park worked on cryogenic power electronics, supercritical fluids, and high-frequency HTS AC loss analysis in addition to his research on the dielectric properties of gases and plasmas.

Abstract
Election hacking, power grid cyber-attacks, troll farms, fake news, ransomware, and other terms have entered our daily vocabularies and are here to stay. Cybersecurity touches nearly every part of our daily lives. Most importantly, national security and economic vitality rely on a safe, resilient, and stable cyber-space. We rely on hardware devices, software platforms, and network systems to connect, travel, communicate, power our homes, provide health care, run our economy, etc. However, cyber-threats and attacks have grown exponentially over the past years, exposing both corporate and personal data, disrupting critical operations, causing a public health and safety impact, and imposing high costs on the economy. In this talk, we will motivate the need to look more closely to cyber-physical systems security. We will provide a research perspective and discuss security threats, challenges, and countermeasures related with the cyber-physical infrastructure of power systems. We will also discuss the need for an accurate assessment environment, achieved through the inclusion of hardware-in-the-loop testbeds.

Title: Shape Data Analysis for Fault Detection in Power Distribution Systems

Presenter: Dr. Reza Arghandeh, Professor, Department of Computing, Mathematics, and Physics and Department of Electrical Engineering at the Western Norway University of Applied Sciences, Norway

Time: 2:00 -3:00 PM, Friday, February 8, 2019

Location: B134, FAMU-FSU College of Engineering

Abstract

Massive data available from new measurement devices such as phasor measurement units (PMU) in the power distribution systems have opened up further possibilities for better diagnosis and identification of abnormal events. However, more advanced machine learning methods are needed to analyze such high resolution and high-quality data while preserving the structure of the data to extract the necessary information. This talk presents the use of the “shape” of the data as a novel feature to improve machine learning methods so-called Shape Data Analysis  (SDA) for fault detection in power distribution networks. The theoretical tools provided by  SDA are used to better characterize different patterns emerged under different electrical fault conditions. The findings are supported by the actual data achieved from a Power Hardware-in-the-Loop (HIL)  test bed.
