Unit Description and General Aims

Electric power systems have a major impact on the environment and this impact covers all areas of the system, from the generation of the power, the transmission and distribution and the end use of the electrical energy. The various impacts on society are extremely wide in scope and range from immediate and simple aesthetic effects, such as overhead lines, through to health problems. In addition there are the long term impacts on the environment such as those resulting from greenhouse gases, from nuclear radiation and more simply from the disposal problems of mineral insulating oil.

The scope of the unit will be wide-ranging and will cover (i) the impact of generation on the environment, including the climate and the general public, (ii) the impact of transmission and distribution on the environment and (iii) the effect of the various forms of electrical energy utilization on the environment and on health.

Generation: Greenhouse gas emission including SF6 and CH4, Sox and Nox, nuclear power generation and disposal issues, water pollution, safety hazards with PV systems, wind turbine issues

Transmission & Distribution: Line losses, Electric and magnetic fields, RF interference, AC vs. DC, negative ions, clearance requirements, substation land needs, non-mineral oil use, PCB disposal, mineral oil disposal, vegetation management, lightning protection and performance, fire ignition by overhead lines

Utilization: Industrial processes and hazards generated: steel mills, arc furnaces, Al refineries, etc.

Furthermore, this unit will consider the sustainability of the power system operation as a major factor in the operation of modern power systems, including the interaction between the three basic components of the environment, the economy and the society. While renewable energy generation is seen as a panacea to many problems of climate change and sustainability issues, it does, nevertheless, have a major impact in terms of use of resources in the manufacturing phase and thus it is of interest to perform life cycle analyses on some of the renewable methods to determine what positive or negative benefits they may develop over their operating life.

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:
 
1. Analyse the operation of electrical energy systems in terms of their energy efficiency, uses of materials and their environmental impact.
Bloom’s Level 5
 
2. Analyse the electrical energy losses in the various aspects of the supply system and to understand the ways in which such losses can be reduced and minimized in practice. Line and transformer losses, lightning system evaluations.
Bloom’s Level 5
 
3. Demonstrate knowledge of the potential hazards and degradation properties of  materials used in electrical energy supply, with knowledge of their disposal and safe use in electrical equipment.
