30.117 Electric Power Systems Analysis and Design

Home / Education / Undergraduate / Courses / 30.117 Electric Power Systems Analysis and Design

This is a course in electric power systems. Topics include: overview of electric transmission and distribution networks; ac transmission lines and cable systems; fundamental principles of major power system components – generators, transformers and motors; characteristics and requirements of power system loads; power system operation and control; earthing and safety requirements; faults in power system and protection; design of industrial and commercial distribution for mission-critical facilities; reliability analysis, risk assessment, safety and maintainability considerations; power quality and interface issues with renewable and alternative energy sources.

This subject is endorsed by PEB (Professional Engineer Board) Singapore.  It is an essential subject for electrical engineering, which fits into EPD Electrical Engineering specialisation track curriculum and also requirement for a student in applying as a practicing engineer after graduation in Electrical Engineering.


Prerequisites will be strictly enforced with a grade of at least a Pass.

Course Lead/Main Instructor


Power system in our context covers Power & Energy analysis and design.  This is an essential course for all electrical engineering disciplines and also for those dealing with machinery (mechanical engineering).  For industrial robot, eg. robotic arms, this is a basic requirement to understand power system, eg. three phases drive.

Learning Objectives

  • Recognize and describe the structure of a typical transmission and distribution networks.
  • Appreciate the complexity of power system operation and control.
  • Analyze performance of major power system components.
  • Evaluate the basic power system in terms of reliability, safety and maintainability.
  • Recognize the needs for matching power supply to the requirements of the loads.
  • Describe the roles of smart grid in power system network.

Measurable Outcomes

  • Distinguish, summarize and analyze various structures of a typical transmission and distribution networks.
  • Formulate, explain and assess the complexity of power system operation and control.
  • Utilize the analysis method and calculate the critical parameters associate with the performance of the major power system components.
  • Examine and rate the basic power system in terms of reliability, safety and maintainability.
  • Explore different analysis techniques and calculate the matching requirement of the loads to the power supply.
  • Outline the implementation of smart grip in power system network.


30.117 is a 12 unit subject (5-0-7), which means that the overall weekly time commitment is, on average, approximately 12 hours.  The actual workload will depend on a number of factors, including the ability of design teams to plan and schedule their time efficiently, the scope chosen by design teams, self-study, homework time. Workload comprises participation in Design, Concept, Implement & Operate (2.5 hours per week), Reflection & Interaction (2.5 hours per week) and non-guided project work (7 hours per week, non-assigned contact time, group meetings, lab note and communication preparation) per week.
