I. Power Networks

ECE520H1 Power Electronics



ECE526H1 Power System Protection and Automotion

This course presents the concepts of short-circuit fault analysis, protective relaying, and automation in power systems. The course starts by discussing the causes and types of short-circuit faults using real-world examples. The consequences of faults for different power system components are reviewed using event reports from field data. The method of symmetrical components for analyzing unbalanced three-phase systems is introduced. Analytical methods and computer-based approaches for deriving fault voltages and currents are discussed and the effect of system grounding during transient conditions, including faults, are introduced. Students also learn the concept of power system automation and its role in monitoring, protection, and control of modern power systems. Critical devices used in an automation system, such as breakers, relays, reclosers, capacitor bank controllers, and tap changer controllers are presented.


ECE1030H Space Vector Theory and Control

Prerequisite:  ECE533H1 or equivalent
Please note: enrolment limited to 15 students

The course presents the general theory of dynamic modelling and control of the voltage source converter using space vectors. Applications include: active filters, FACTS (flexible AC Transmission Systems) controllers, VSC based HVDC systems, motor drives and most grid connected storage systems and renewable energy sources. Co-ordinate transforms necessary for the analysis of these devices are presented: space vectors, synchronous reference frame quantities, complex Fourier components and their relations. Converter controls are developed using both continuous time and discrete time space vector control concepts. In addition, state space modelling methods are employed for the study of interactions between a dc/ac converter and the network. The course typically includes an extensive laboratory component.


ECE1049H Special Topics in Energy Systems: Power System Protection

This course reviews the fundamentals of short-circuit fault analysis for the power grid and discusses the expected features of a reliable protection system. The measurement devices used in protection systems are introduced, and their non-ideal features are discussed. This course introduces different types of overcurrent relays, their operating principles, coordination methods, and potential applications. Various methods for directional protection of the systems with bi-directional fault currents and the respective coordination strategies are explained. The course discusses the basic principles and coordination methods of distance protection for transmission lines. Different types of pilot protection schemes based on distance and directional relays are introduced. The course presents a detailed discussion on the operating principles of differential relaying for lines, transformers, motors, generators, and buses. Throughout the course, computer simulations of power systems are used to analyze protection functions.

General aspects of high voltage ac/dc systems, principles of HVdc systems, HVdc control, harmonics and filters. Small-signal dynamics of HVdc/ac systems and eigen analysis, subsynchronous oscillations, interarea oscillations, harmonic instability. Large-signal dynamics in HVdc/ac systems. Introduction to the EMTP and the EMTDC software packages for the analysis and design of HVdc/ac systems. Introduction to multi-terminal HVdc systems. A basic background in power system analysis is strongly recommended.


ECE1059H Special Topics in Energy Systems: Grid-forming Converters

Exclusion: ECE1055H

This course covers principals of (i) operation, (ii) modeling, (iii) controls, and (iv) dynamic behavior of grid-forming AC-DC power electronic converters for electric power grid applications. The focus is in on the 2-level voltage-sourced converter (VSC) and the modular multi-level converter (MMC) configurations. The subjects will be discussed in the context of bulk-power generation, transmission, and utilization and thus extensively inter-related to the controls and dynamics of legacy synchronous machines.

This course is an intermediate-level course and the required background includes:

  • undergraduate-level concepts of power electronics;
  • undergraduate-level concepts of systems control;
  • undergraduate-level concepts of power systems analysis;
  • graduate-level coverage of synchronous electric machines dynamics;
  • familiarity with software simulation platforms PSCAD and/or EMTP-RV.

ECE1092H Smart Grid Case Studies

The course presents case studies of old and new Smart Grid applications in overhead electric power networks.  Each case study has components that include a history of the technology, a simplified treatment of the specific threat or opportunity, and the implementation issues in communications and sensor installation and maintenance.  The treatment makes use of relevant industrial standards including IEEE and IEC.


ECE1093H Electrical Insulation Design and Coordination

The course organizes the voltage stresses that appear in high voltage systems in terms of amplitude, duration and occurrence. Suitable models for electrical breakdown and withstand are developed, with specific emphasis on outdoor insulation in adverse weather conditions.  The functions of surge protective devices, grounding and other overvoltage control measures will be discussed.  The treatment makes use of empirical models typical of relevant IEEE and IEC industrial standards.

Recommended Prerequisites: ECE359H1, ECE413H1

The course introduces the objectives, components and principles of grounding systems. Empirical models for risk of electrocution and perception are identified, using relevant IEEE and IEC industrial standards. Methods for characterizing soil resistivity are demonstrated and then related to electrical characteristics of typical service entrance, line and station ground grid electrodes. Much of the course focus is on 60-Hz analysis but the scope will include considerations for dc and lightning impulse performance, including testing of transfer impedance from lightning protection systems to victim circuits and components.
