| Description:
| Aims: To provide a detailed understanding, in terms of application and operating principles, of the main types of relay used for the protection of power systems. Learning Outcomes: After successfully completing this unit students will be able to: divide a power supply network into manageable units suitable for protection; describe the requirements of a variety of protection schemes; calculate relay settings for a number of typical distribution network applications; analyse transducers through their equivalent circuits; apply and coordinate overcurrent relays; apply distance protection under varying system conditions; apply current differential protection and anticipate the communications requirements; select appropriate auto-reclose relays; explain the advantages and operation of modern numeric relays. Skills: Application of the information, techniques and methods detailed in the unit material, to the proposal of, and the carrying through of, appropriate solutions to engineering problems in the protection of electrical power distribution systems. Taught, facilitated and tested. Content: An introduction to the concepts of protection; unit and non-unit protection; zones of protection; fuses; electromechanical and electronic relays; numerical technologies; current and voltage transformers - non-conventional transducers; overcurrent protection by fuses and overcurrent relays; unit protection of feeders - traditional and digital; communications for protection; three-phase distance protection and schemes; directional earth-fault protection schemes, including distance relaying; numerical distance relaying; transformer protection; busbar protection - frame-earth, differential, numerical schemes; motor protection - stator winding, overload, phase unbalanced; generator protection - short-circuit, stator-earth, rotor-earth; embedded generation and utility network protection; auto-reclosure relaying; substation automation including protection, control and automation - the intelligent electronic device. |
