Digital modelling of DC plasma torches (Part 2)

The use of plasma torches for the gasification of waste products enables the transformation of waste into clean energy with no residual by-products. As a result of the extremely high temperatures generated by plasma torches (from 5,000°C to 20,000°C depending on the type of gas used), torch and reactor modelling represent a technological challenge for designers. Digital modelling of the plasma flare and the electrical arc in the plasma torch will contribute to a better understanding of the degradation of the torch’s internal components.

Design and implementation of a plasma power source

This project calls for the design and implementation of a power source of 20 kW and 600 V. The power source will serve several functions in the labs at Atlantic Hydrogen Inc. (AHI), chief among which is to create thermal CC plasma with current control capability. The source will consist of a static converter that converts alternating current into direct current (AC-DC), a tri-phased transformer to reduce tension throughout the network and ensure galvanic isolation, several transducers (current, tension), control circuits, and a dedicated digital processor.

Natural gas development and grassland songbird abundance in Southwestern Saskatchewan: the impact of gas wells and cumulative effects

Native prairie is critical to the survival of avian grassland specialists. This internship will determine the extent to which recent natural gas development on native grasslands in Southwestern Saskatchewan influences grassland songbird abundance. Natural gas activity may negatively affect bird abundance via habitat degradation (well density, noise pollution, human disturbance, exotic species, soil compaction, gas wells etc.) and loss.

Potential Function Based Secondary Control of Microgrid

The new trend in electric power systems is to incorporate distributed energy resource (DER) units into the main grid. Such DER units can form a microgrid if they are in close proximity of each other and are connected to the main grid through a single point of common coupling (PCC). If for any reason the microgrid becomes separated from the main grid, for example in a case of a fault occurrence, the new paradigm of power systems (Smart Grid) necessitates that the microgrid continues to operate in this islanded mode.

Measuring material nuclear properties for Prompt Gamma Neutron Activation (PGNA) spectroscopy

The objective of the research project is to design a method of measuring the neutron and photon attenuation properties of complex samples (such as toxic waste or mining ore) with a wide range of shapes and masses. Measuring these properties will permit accurate analysis of the sample’s elemental composition via Prompt Gamma Neutron Activation Analysis (PGNAA). Currently, accurate analysis of samples via PGNAA is typically restricted to low mass (<100g) samples with controlled geometries. This limits the usefulness of PGNAA.

Study of dielectric response in progressive tension-increase tests on stator windings on large rotating machines

Progressive tension-increase tests are one of the diagnostic methods currently used by Hydro-Québec for the stator isolation system on its hydro alternators. This test is part of MIDA, an expert diagnostics toolkit in use at Hydro-Québec. The effect of certain flaws affecting the quality of the signal during the test, especially with regard to the problem of copper-insulation delamination, has yet to be investigated.

Development of Solar Hot Water Heater Performance Monitoring Protocol and Equipment

The internship will entail the development of a flexible and robust data acquisition and monitoring system for the large‐scale long‐term performance evaluation of residential Solar DHW heating systems. The literature review will guide different alternative solar heating options. The expected result will provide flexible and portable hardware/software equipment and survey protocol for large scale monitoring and evaluation of solar DHW systems.

Design Cycle for power electronic systems: from simulation to hardware implementation

Industrial Systems have become increasingly complex and hence their design requires extensive new tools and techniques. Computers and computer simulations play an important role in helping the design engineers in finding suitable solutions to the design of modern industrial systems. This Mitacs-Accelerate internship aims to improve the methods and techniques used in the computer aided design of power electronic systems incorporating optimization and combining it with a simulation program.

Robust Efficient Estimation of Energy Use

Predicting hourly building energy use from environmental input variables can help to increase energy efficiency of buildings, and so contribute to global sustainability. Small Energy Group, a Vancouver-based energy management software company has been working on this challenging prediction problem. Small Energy Group has collected energy data on particular buildings so that the building owners and managers can identify ways to lower their energy consumption.

An Improved Wide-Band Dynamic System Equivalent Technique for Real-Time Digital Simulators

Real-time simulators are increasingly important in power system studies and equipment tests by manufacturers, universities, research institutes and power system utilities. Yet their capability for accurately simulating some aspects of very large systems is limited by the burden of additional hardware requirements. Thus, the aim of this project is to develop an improved wide-band system equivalent technique for the real-time digital simulator (RTDS) that will improve its capabilities on super-large power systems.
