The course gives a deep understanding of electric machines: theory, applications,steady-state, and (for the dc brush machine) dynamic performance with speed andcurrent control including relevant theory. The student is encouraged to considerenvironmental aspects, such as energy-efficient drive systems, and recycling ofcopper.ENM060 Power electronic converters(7.5 credits) Torbjörn Thiringer and Massimo BongiornoSustainable energy technologies such as wind power, photovoltaic, wave energy,utilization of fuel cells and hydrogen as energy carriers all need power electronicsconverters in the interface to the electrical load. Most of the techniques for energysaving at the electrical load side, such as motor speed control in fans and pumpsas in heat pumps and energy saving lamps, also need power electronics. Thecourse presents an introduction to the converter circuits of power electronics usedto convert and control electric energy. Methods for designing converters arepresented. How to select converter topologies, power semiconductors and passivecomponents is also briefly covered.ENM065 Power system operation(7.5 credits) Tuan LePower system operation engineers (dispatchers) have one of the most challengingjobs in the electric power industry. They must have a basic understanding ofvarious types of power system generation, plant controls, protective schemes,control of voltage and frequency, overall dynamic behaviours of power systems(transient and voltage stability), and the fundamentals of economic operation. Inaddition, they must also have the ability to monitor and quickly analyze emergencysituations and take appropriate corrective actions promptly. The purpose of thecourse is to give students knowledge of and exposure to these dynamics.Students will have a better understanding of some of the operating and controllingissues of a power system through laboratory work as well as through simulationsoftware.ENM070 Power electronic devices and applications(7.5 credits) Torbjörn ThiringerThis course builds on ENM060. The aim of this course is to enhance students‟knowledge regarding the design and application of power electronic converters.Some examples are: design of driver circuits of various qualities and for variousapplications, design of snubber circuits for improved EMI and loss operation,thermal calculations and considerations. In addition a goal is to explain theconcept of soft-switching converters such as resonant and zero voltage current aswell as zero voltage switching converters. Moreover an objective is to provide thestudents with knowledge of power electronic equipment connected to the grid such19 |
