Typically, the identification of maximum transient surges (TOV) for the Medium Voltage collector systems and the establishment of strategies for TOV suppression is performed via detailed engineering studies for wind farms, however the experience is relatively new for large-scale solar plants. This presentation reviews this topic and offers recommendations on how the circuit breakers could be configured at the distribution level to provide acceptable levels of protection and reliability.

Webinar: Solving Drive Input Power Quality Issues for the Oil and Gas Industries

This webinar will introduce the basic principles of input power quality issues related to VSDs with various topologies utilized in LV and MV VSD’s designs commonly used in the oil field industry. The input power quality issues (system side power quality) will be investigated: line-side voltage and current harmonics, voltage input range and regulation, voltage disturbance (transients, sags, swells, interruptions), voltage waveform notching. Special attention will be given to system grounding methods and equipment grounding. The presentation also considers the impact of the VSD on increased generator loading, reduced power factor, and overheating of cables and transformers. Present day solutions based on input filtering will be described. It will be shown these input power quality issues will increase equipment failure, or at least tripping of equipment, as well as increasing operating costs. The webinar will include filter design techniques reviewing various input drive harmonic mitigation solutions such as line reactors (chokes), phase-shifting drive transformers, and drive input filters (passive or active). A variety of real-world examples will be shared to illustrate these concepts, symptoms and solutions.

Most mass transit rail systems operate using high power DC sources to power the operating trains carrying passengers. The DC power is supplied by what are called DC Traction Power Substations (TPSS). These specialized substations have the necessary equipment to safely and reliably convert incoming AC power into outgoing DC power to feed the rail system. This webinar discusses the basic power equipment elements, applicable industry standards as well as industry practices applied to DC Traction Power Substations found across North America with a focus on Light Rail DC Traction Power Substations.

Webinar: Proximity Tracing in an Ecosystem of Surveillance Capitalism

Date: Aug 26th, 2021, 04:00 PM to 05:00 PM (MDT)

Presented by: Joel Reardon, Assistant Professor at the University of Calgary

Proximity tracing apps have been proposed as an aid in dealing with the COVID-19 crisis. Some of those apps leverage attenuation of Bluetooth beacons from mobile devices to build a record of proximate encounters between a pair of device owners. The underlying protocols are known to suffer from false positive and re-identification attacks.

Dr. Joel Reardon, Assistant professor at the University of Calgary, presents evidence that the attacker’s difficulty in mounting such attacks has been overestimated. Indeed, an attacker leveraging a moderately successful app or SDK with Bluetooth and location access can eavesdrop and interfere with these proximity tracing systems at no hardware cost and perform these attacks against users who do not have this app or SDK installed. We describe concrete examples of actors who would be in a good position to execute such attacks.

Teleoperated (leader-follower) robotic systems offer advantages to the user of increased dexterity and precision, tremor filtering, motion repeatability, and the possibility of autonomous or semi-autonomous functions. In the time of a pandemic, such as COVID-19, they provide a means of improved safety for healthcare workers through the possibility of performing certain functions from short or long distances, such as patient monitoring, assessment and treatment. However, these teleoperated systems also have some disadvantages, primarily as a result of limitations of the current technology. These issues will be discussed in the talk in the context of two specific areas of application: robotics-assisted medical interventions and robotics for neurological movement disorders. Particular focus will be on issues arising from the absence of accurate haptic (sense of touch) feedback which prevents reflection to the user of realistic interaction forces between a robot and a patient or objects in the robot’s environment. The role of haptics-based teleoperation will be discussed based on experimental studies to highlight the key issues associated with incorporating force sensing, haptics and teleoperation in patient-oriented robotic systems and the advantages and potential uses of such interaction in specific applications.

An esteemed London, ON, IEEE Member, Dr. Rajni Patel, has been awarded the IEEE Canada A.G.L. McNaughton Award for 2021. Recipients of this medal are outstanding Canadian engineers recognized for their exemplary contributions to the engineering profession.

As part of recognizing this award, the IEEE, via the event primary sponsor, the IEEE London, ON, Section, Chapter EMB18, and via the event co-sponsor, the IEEE Southern Alberta Section (SAS) Chapter EMB18, have invited Dr. Patel to provide an overview of his research interests, already listed above.

Webinar: WindCharger Battery Energy Storage System

WindCharger is Alberta’s first utility-scale, lithium-ion energy storage project. It uses Tesla’s Megapack technology and is the first installation of this technology in Canada’s northern climate. The design team collaborated with the Alberta Electric System Operator (AESO) to establish the project-specific, electricity grid interconnection requirements and applicable standards.

WindCharger has a nameplate capacity of 10MW, a total storage capacity of 20MWh and can be fully charged in approximately two hours. This technology supports fully behind-the-fence renewable energy, powered by TransAlta’s Summer view II Wind Facility. The project’s total capital cost was approximately $14.5 million (CAD), approximately 50 percent funded through the support of Emissions Reduction Alberta. BBA was the lead design consultant and Iconic Power Systems completed the project’s construction.

This presentation will elaborate on the key factors that led to the selection of the technology, including performance and utility requirements. Additional information will be provided about winter operation considerations.
