In this unit students will acquire advanced theoretical knowledge, critical analytical and practical skills which can be applied to investigation and resolution of complex problem solving scenarios. The unit material has been developed to enhance students' communication skills, individual and group project participation and other professional capabilities important to insulation coordination and sub-station design principles. The unit is designed for students specialising in the field of Electrical Power Engineering and will upgrade knowledge, skills and application of skills related to power sub-stations design and insulation coordination. This follows the procedures and protocols of international standards like AS1824, BS 6651, IEEE 1313.2 and 998, and IEC 62305 and 60099. These standards provide guidelines to design sub-station layout for transmission and distribution networks with a view to protect costly power apparatus from random occurring overvoltage transients. The design rules of sub-stations are broad and cover many areas of civil, mechanical, material science, life science and telecommunication engineering. This unit also highlights the steps involved in design and analysis of sub-station layouts. The theoretical and practical knowledge gained from this module notes and Sub-Station visit is the excellent foundation for those students who will start to work and design in the new and operating sub-station environment.

Learning Outcomes

On successful completion of this unit, students will be able to:
  1. Design a sub-station layout for transmission and distribution systems, taking into account future power supply demand requirements;  
  2. Adhere to stringent requirements of insulation coordination principles to power system design;  
  3. Devise overvoltage protection systems on random occurring lightning and switching transient surges;  
  4. Demonstrate with real world sub-station layouts and analysis with the learned concepts can strengthen the generic concept followed in the industry;  
  5. Survey and conduct a case study for a site specific case; and  
  6. Propose, conduct and justify computational modelling to meet industry standards.
