Insulation Coordination and Voltage Transients in Large Industrial Power Systems
Presented by: Rasheek Rifaat and Xiaoke (Ken) Duan
Date: Monday November 25, 6:30pm to 8:30pm. Doors open at 5:45pm.
Location: TransAlta T1-Auditorium, 110 – 12 Ave SW, Calgary, AB
Register at: Advance registration only. Registration closes Nov 21 or once full.

Large industrial facilities have their own medium and high voltage systems and many of them are connected to the Alberta Interconnected Electric System (AIES) at higher voltage levels than previously done. To ensure insulation system secure and reliable design and operation, insulation coordination should be evaluated, and high voltage transient studies be should performed where applicable. This presentation provides an introduction to aspects associated with performance of insulation coordination, selection and use of surge arrestors for the protection of electrical equipment, and applicable North America and International Standards. The presentation also touches on other high voltage transient studies such as breaker Transient Recovery Voltage (TRV) and fast and very fast voltage transients; when to perform them, and what is needed to perform them such as necessary equipment information and required software to perform the analysis.

Title: Sub-Synchronous Interaction and Harmonic Control Instability Associated with HVDC and Wind Plant Installations
Date: April 3, 2019
Time: 6:30-8:30pm
Location: 110-12AV SW
Details: Registration

Sub-synchronous interactions (SSI) are a family of physical interactions that involve exchange of energy between a generator and a transmission system at ac frequencies below the system nominal frequency. They include sub-synchronous resonance (SSR), sub-synchronous torsional interaction (SSTI), and sub-synchronous control instability (SSCI). SSR is a phenomenon that can cause increased fatigue or critical failure of generator turbine shaft systems due to an energy exchange between the generator and a series-compensated transmission system, either through sustained or poorly damped oscillations, or transient effects. SSTI occur when an interaction happens between an HVDC link, FACTS device, or other power electronic controller and the mechanical mass system of a generator. The power electronic controller can exhibit negative damping at sub-synchronous frequencies, which can cause un-damped or growing oscillations in the known mechanical torsional modes of oscillation in the generator shaft system. SSCI phenomenon is a control interaction that can occur between any power electronic devices, such as wind turbine, and a series-compensated system. The oscillations resulting from SSCI may grow very quickly. Another SSCI phenomenon is the interaction between power electronic controllers such as grid-connected inverters for renewable energy sources integration. Such resonances can be both sub-synchronous and super-synchronous and may lead to inverter control instability and other dynamic problems when the connected grid is becoming weak.

The objective of this Seminar is to provide an introduction to SSI phenomena including SSR, SSTI and SSCI. To give a guide on how to identify potentiality where SSTI and/or SSCI may be an issue; how to study the phenomena; how to control, mitigate, and/or protect against any adverse effects associated with these interactions; and potential types of system changes or additions that would require equipment owners and/or operators to re-examine their system for the possibility of SSTI and/or SSCI.

Title: Privacy Implications of the Internet of Things
Date: March 5, 2019
Time: 5:30-9pm
Location: 110-12AV SW
Details: Registration

Big data analytics promises to bring many benefits including increased security, safety, insight, and understanding about how to best support highly valued public services. Conversely, such analytics could be used to violate inappropriately individual privacy that could bring both immediate harm and cause long-term unintended consequences unless the data is secured and protected. With the emergence of the Internet of Things, the volume of data that will be subject to analysis will increase many times over. The nature of the data will also change because these devices will capture a wide-range of human activities that could be linked to individual behaviors through deep analytics. This talk will discuss how personal privacy is at risk now and how the introduction of the IoT complicates and expands related concerns.

Title: Safety Instrumented Systems – Avoidance and Control of Systematic Failures
Date: February 5, 2019
Time: 5:30-9pm
Location: 110-12AV SW
Details: Registration

Safety Instrument Systems (SIS) intend to control risk of hazards to a tolerable boundary by reducing dangerous failures rate. There are two types of failures; random and systematic. Random failures occur at random times and result from one or more degradation mechanisms. Systematic failures, however, are related to a deterministic way to a certain cause, which can only be eliminated by a modification of the design or manufacturing process, operational procedures, documentation or other relevant factors. Both systematic safety integrity (to avoid systematic failures) and hardware safety Integrity (to avoid random failures) are needed to meet the required risk reduction target for a SIS. Thus, if systematic integrity is missed, much is neglected. Studies show that many catastrophic accidents occurring in process industries address multiple systematic failures. Unlike random failures, systematic failures cannot be analyzed straightforwardly. The author’s experiences in automation field of process industries shows avoidance and control of systematic failures in SIS are not being highlighted as much as random hardware failures. This talk focuses on systematic failures and discusses procedures, techniques and measures to be used for avoidance and control of systematic failures.

Location: 110 – 12 Ave SW, Calgary, Alberta
Register at: Advance Registration Only. Registration closes 13 May.

The convergence of multiple technologies has created the potential for communities to get much more
out of public and utility assets. No one knows city infrastructure better than the local municipalities and
utilities, which gives these stakeholders a unique position to help develop smart cities that connect basic
neighborhood infrastructure to synergistically improve operational excellence, revenue potential and
sustainable lifestyles. The presentation will explore: What are the smart cities; the role of municipalities
and utilities in enabling the transition; who are the key players and allies?
