Summary of Content

This module examines the design, commissioning and testing and operation of high voltage (HV) plant. The methodologies for transferring power between AC and DC systems will be developed, increasing understanding of power electronic applications to HV systems. The module outlines the range of insulation materials and systems which are variously applied within HV systems and the mechanisms by which they degrade. The module addresses the methods which can be applied to monitor and assess the condition of HV equipment and how this can be used to sustain operational life of existing infrastructure. The module will outline operation of AC and DC equipment used in transmission and distribution networks and the impact that equipment failure would have on system integrity. Indicators of overstress and degradation of equipment insulation and the measurable parameters which arise will be outlined, considering the physico-chemical nature of detection techniques and the requirement in modern applications for data fusion for informed condition assessment. The module aims to develop a student's understanding of the stresses which components and sub-systems are subjected to whilst in service. They will also develop understanding of how these stresses can cause degradation and ultimate failure of HV equipment. The impact and effect of transferring power from AC-DC and DC-AC on inherent stresses within the equipment will be considered. The student will apply their understanding to the analysis of individual items of plant to determine the likely stresses prevalent, the consequences and the design features which should be incorporated to alleviate the problems. The student will apply the knowledge gained to evaluate when, if financially justified, a condition monitoring policy should be adopted and how this should be realized. The analysis of equipment design and ability to explain and justify appropriate condition monitoring methods is embedded within the module. The need for professional engineers to be aware of their impact on profitability of an organization and the ethical impact of the decisions made on wellbeing of company staff and customers is inherent to the module. The module activities provide an opportunity for an individual to further develop and demonstrate professional and transferable skills that will prepare them for a career in engineering.


HV Systems : Overview of AC and DC HV plant, insulation systems, insulation system coordination, the design, commissioning and testing of HV systems Stresses in HV equipment : In-service stresses in equipment and systems, i.e. electrical, mechanical, thermal and environmental stresses in motors, generators, transformers, cables, outdoor insulators and circuit breakers. Evaluation of Stresses and performance : Methodologies for evaluating the likely stresses on a given item of plant. Design features to accommodate/alleviate such stresses. Evaluation of performance. Measurable Phenomena : Measurable phenomena associated with degradation/normal operation: including light, heat, sound, electromagnetic radiation, physical/chemical changes for a variety of HV equipment. Measurement Technology : Measurement instrumentation/transducers available to characterize degradation phenomena: including generic forms of instrumentation for given phenomena and specific, commercially available instruments, their advantages, disadvantages and limitations. Measurement Strategy : Single vs multi-parameter measurements and computer control/advanced signal processing techniques vs simple manual measurements, advantages, disadvantages and limitations. Condition Assessment Strategy : Condition and Reliability assessment for individual equipment and sub-systems, financial implications of loss of output and repair/replacement, different approaches to equipment aging and reliability.

Learning Outcomes

On completion of this module students should be able to:Understand the process of design, commissioning and testing of HV plant and the mechanisms which stress power plant and systems under typical in-service conditions.Evaluate, for a given condition, the likely/possible stresses on a given item of plant or system and application of outcome to the design of power plant components and sub-systems.For defined equipment and situations, outline the measurable phenomena appropriate to condition monitoring and assessment.For defined equipment and situations, outline advantages and disadvantages of adopting a condition monitoring policy and the impact of the defined strategy on the ethics and economics for a business.Evaluate, for a given situation, the specific instrumentation to be used and the measurement strategy. Demonstrate ability to report upon an aspect of condition monitoring of HV equipment in a written report.

Teaching / Learning Strategy

The main teaching method will be lecture/seminars with industrial visits or guest lectures to relate theoretical concepts to practical experience. The materials presented will, in addition to using pertinent information from books and journals, draw upon experience and resources available to staff through relevant EPSRC funded work and industrial collaboration carried out by staff. Students will be expected to undertake directed reading and self-learning exercises on topics related to High Voltage Technologies and Condition Assessment prior to lectures and as the basis for coursework. Tutorials and laboratory demonstrations will be used to reinforce the module material and to discuss issues raised by the directed reading. Students are provided with feedback on coursework within 3 working weeks of submission. Feedback is also provided via a variety of mechanisms, including during the meeting with their group mentor/supervisor.
