SUB-SYNCHRONOUS INTERACTION AND HARMONIC CONTROL INSTABILITY ASSOCIATED WITH HVDC AND WIND PLANT INSTALLATIONS

IEEE-NCS, PES/IAS Chapter Presents
Thursday, April 4th, 2019, 6:00 to 8:30pm, doors open at 5:30pm

Sub-Synchronous Interaction and Harmonic Control Instability Associated with HVDC and Wind Plant Installations

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.

EDMONTON IAS/PES CHAPTER EVENT – TRANSFORMER INSTALLATION AND TESTING

IEEE-NCS, PES/IAS Chapter Presents
Tuesday, February 12th, 2019, 6:00 to 8:30pm, doors open at 5:30pm

Transformer Installation and Testing

This presentation will discuss the processes involved with oil-filled transformers including those of:

  • Receiving a transformer after transport to a substation site
  • Assembly and processing of a transformer at site
  • Testing of a transformer to verify its suitability for service
  • Discussion of integrating the transformer into the power system

Transformers are required in almost every power supply situation. The installation and testing of the transformer verifies its condition at the time it is ready for service as well as forming the baseline or signature tests for all future maintenance and later condition assessment or analysis.

The manner and processes that are used to receive, assemble, process and test the transformer are of fundamental importance to the long life of the transformer.

Embedding Reliability Engineering Practices, A Practical Example

IEEE-NCS, PES Chapter Presents
Tuesday, November 27th, 2018, 6:00 to 8:30pm, doors open at 5:30pm

Embedding Reliability Engineering Practices, A Practical Example

Asset Management, Reliability engineering, predictive and preventative maintenance; these are the new catch phrases of the day. But what do they really mean? What does it look like when implemented? Are reliability engineering and asset management the same thing? How do I present and argue the inherent value of embedding these practices into my business and drive not only compliance but a commitment to doing them and improving them? In today’s talk we will endeavor to help put the topics of Asset management, Reliability engineering, predicative and preventative maintenance in context for electrical utilities, and provide guidance to support your journey in successful implementation and sustainment of these practices.

Key Takeaways:

  • How do you engage the business to deliver?
  • What does a maintenance strategy or reliability practice look like, and where does it fit in ISO55000?
  • How do you sustain and embed what you’ve built?

Granular Computing: Pursuing New Frontiers of Artificial Intelligence and Data Science

IEEE-NCS, PES and Comp/Comm Chapter Presents
Tuesday, November 20th, 2018, 6:00 to 8:30pm, doors open at 5:30pm

Granular Computing: Pursuing New Frontiers of Artificial Intelligence and Data Science

 

Presented By: Prof. Witold Pedrycz

Abstract:

Artificial Intelligence (AI) has been enjoying a great deal of interest in the recent years owing to its successful applications reported in various areas including robotics, computer vision, and a plethora of systems engaging natural language processing. Data Science becomes instrumental in data analysis discovering essential dependencies and building prediction and classification models.

We advocate that bringing the concepts, methodologies, and formal frameworks of Granular Computing into the area of AI and Data Science can open new and promising avenues of further research and applications. Granular Computing is defined as a coherent and unified platform of acquiring, processing and communication of information granules delivering a highly needed abstraction mechanism.

The talk is self-contained: the principles and formalisms of information granules along with their underlying design principles are discussed in detail. It is shown that the notion of information granularity assumes an important position by bridging the gap between symbolic and sub-symbolic way of processing realized in AI.

The roles of information granules in various faculties of AI such as knowledge representation, concept formation and their hierarchical organization, problem solving mechanisms are elaborated in detail.   It is also emphasized that information granules play a visible role in revealing and characterizing interpretable relationships (dependencies) in data.

Power System Harmonics of Modern Nonlinear Loads w/ Young Professional – Intro to High-Speed Motor Bus Transfer

Tuesday, October 23rd, 2018, 6:00 to 8:30pm, doors open at 5:30pm

Power System Harmonics of Modern Nonlinear Loads w/ Young Professional – Intro to High-Speed Motor Bus Transfer

 

Young Professional Opening Talk: Intro to High-Speed Motor Bus Transfer

Presented By: Daniel Lang, P.Eng., PES/IAS Chapter Vice-Chair 

Abstract:

Process conditions in many industrial facilities often cannot tolerate discontinuity of critical loads, even momentarily. Operational continuity is provided mainly by high-speed motor bus transfer schemes. This need for speed comes with a trade-off as these systems require complex high-speed relaying to prevent catastrophic transient torsional stresses being imposed on the motor shaft. This presentation provides an overview of typical high-speed bus transfer schemes and their limitations, as well as the extensiveness of the applicable standards.

IEEE 1547 Standard and DER Interconnection

Please join NCS PES/IAS (Edmonton area) for “IEEE 1547 Standard and DER Interconnection” event:

Many countries have implemented renewables portfolio standards (RPSs) to accelerate the pace of deployment of renewables generation, which are distributed across the distribution power system. As the penetration of renewable power generation increases, electricity grids are beginning to experience challenges, which are often caused by intermittent nature of some common renewable generation types, sudden changes of the output power due to grid disturbances, low short circuit duty of the inverter based generators, and impact on the transmission and distribution system protection.
Due to the increasing amount of Distributed Energy Resources (DERs) interconnections with the Electric Power System, the IEEE 1547 standard is going through a major revision to address some of the technical challenges associated with high penetration of DERs i.e. grid support functionalities, etc.
The participants will learn about the benefits and challenges of the renewable energy resources interconnections as well as major changes to the IEEE 1547, i.e., voltage regulation, response to abnormal system conditions (including voltage and frequency ride through), power quality, islanding, interoperability, etc.
The participants will also learn about the utility concerns/solutions to adopt the revised IEEE 1547 standard.
