Real-Time Simulation Methods of Power Electronic Systems

Joint Webinar with IEEE Power Electronics Society
Presenter:  Dr. Fei Gao, University of Technology of Belfort-Montbeliard
Date:  Tuesday, January 14, 2020, 11:00am EST

Abstract: Real-time simulation and Hardware-in-the-Loop (HIL) techniques emerge as indispensable tools in the design, modeling, testing and validation of modern power electronic systems. Different from an offline simulation, real-time simulation depends not only on the results of logical / arithmetic calculations of the model, but also on physical time (real-time) when these results are produced. Today, high accuracy real-time simulation and HIL of modern power electronics is still a great challenge. Power electronics components models are characterized by their high switching frequency and on-off characteristics. Mathematical models that contain a number of power electronic components can lead to serious real-time simulation problems (e.g. limited simulation time step size, large memory to store circuit topology due to on-off states of power switches, etc.). Solve such mathematical models while meeting the strict time constraint requires the development of specific real-time simulation techniques.

In this presentation, a general introduction of real-time simulation and Hardware-in-the-Loop (HIL) technology is first given. State-of-art modeling approaches for power electronic switches, as well as electric network formulations of power electronic systems are then presented, and their advantages and drawbacks are discussed with commercial solution examples. The main hardware implementation platforms (CPU and FPGA) for real-time simulation models are also compared. At last, a simple example of how to implement a Floating Interleaved Boost Converter (FIBC) model in real-time simulation platform for controller Hardware-in-the-Loop (HIL) application is provided using the previously presented techniques.

New Technologies and Global Energy Efficiency Regulation Developments for Electric Motors and Drives

Sponsored by the IEEE Industry Applications Society
Presenter:  Anibal T. De Almeida, University of Coimbra:  Institute for Systems and Robotics
Date:  Wednesday, January 15, 2020, 11:00am EST

 Abstract:  Energy-efficient motor systems have a huge electricity savings potential, presenting a cost-effective option for reducing GHG emissions. The electric motor market has witnessed a major change in the last decade in several aspects: in technology leading to the availability higher efficiency models, in content with energy-efficiency policies, the need for more sustainable industrial production and in its economy due to increasing electricity prices, all aspects contributing to push the market towards more energy-efficient electric motors.

Additionally, the growing market penetration of Variable Speed Drives (VSD), introducing large energy savings in systems with variable loads, was accompanied by a growing concern over their operating efficiency in full and especially in part-load, as well as in standby mode.

In Europe, recent developments in motors and drives efficiency regulation under the umbrella of the Ecodesign Directive have highlighted the significant savings that can still be achieved in the field by raising the minimum efficiency performance standards (MEPS) for motors and introducing new standards for Variable Speed Drives (VSDs).

This webinar presents an overview of minimum efficiency standards around the World, analyses the relationship between the introduction of new regulations and the development of new technologies, as well as the potential impact in terms of electricity savings and corresponding reduction in GHG emissions.

The increasing number of countries implementing MEPS for motors, together with the growing awareness within governments and industry towards the importance of energy-efficiency and its multiple benefits, has led to the market introduction of new technologies with great improvements in the energy efficiency of motors, which now reach levels well above the IE3 level, known as Super- and Ultra-Premium Efficiency Motors (IE4 and IE5, respectively), and of high-efficiency VSDs.
