banner1
Short Title:Electrical Utility and Power
Full Title:Electrical Utility and Power Systems
Module Code:ELEC7006
 
NFQ Level:Intermediate
 
ECTS Credits:5.0
Module Coordinator:JOSEPH CONNELL
Description:This module will provide the learner with the essentials of the various aspects of modern power system: generation, control, protection, operation, transmission, and distribution.
Learning Outcomes:
On successful completion of this module the learner will be able to
  1. Describe the factors relating to high voltage (HV), substation siting, planning and plant layout.
  2. Select suitable equipment relating to the planning of electrical installation with regard to the requirements of the specification.
  3. Describe the construction, principle and use of electric machines, and carry out steady-state performance calculations.
  4. Understanding of the functional, operational and safety requirements for a high voltage system
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
No recommendations listed
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed
Requirements
This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
