6th Research Symposium on High Voltage and Power Systems

6th Research Symposium on High Voltage and Power Systems

One of the key targets of Abu Dhabi’s 2020 vision is to ‘develop a sufficient and resilient infrastructure capable of supporting the anticipated economic growth’, and to achieve this target, diversification of electricity energy production sources, maintenance and future adaptation of the electricity grid network infrastructure is needed. In line with this vision, the High Voltage and Dielectric Materials (HVDM) research group at Khalifa University aims to carry out advanced fundamental and applied research to help achieve this target. This group, which is part of the Advanced Power and Energy Centre (APEC), focuses on key research areas recognized as fundamental to ensure that high voltage electrical energy systems are protected from disruptions and blackouts while ensuring safety and maximum efficiency; with millions of homes, business and industry relying on the high voltage electrical power grid. The grid infrastructure comprises transmission and distribution lines, high-cost equipment such as transformers, high-voltage cables, insulators, bushings, surge arresters, and circuit breakers and these operate under increasingly challenging and variable electrical and environmental stress conditions. Particularly important for high voltage insulation in the climate of the Gulf, is the requirement for the system to perform under particularly extreme environmental stresses. The challenge is therefore to provide a reliable power supply at high efficiency to a wide variety of industrial, commercial and domestic loads while evolving towards a power system supplied by sustainable and environmentally friendly energy sources.

This symposium, the sixth of its series organized by the HVDM group, builds upon previous successful events and features presentations covering a breadth of research topics within the scope of high-voltage engineering and applications, power systems, power electronics, grid integration of renewables, lightning protection and grounding. Speakers include a mix of researchers and experts from Japanese universities, KUST faculty and researchers, and local universities. It creates a forum for attendants to exchange ideas and discuss future opportunities for collaboration.

Target participants:

  • Faculty, researchers and students in the area of electrical power engineering or related discipline
  • Engineers and technicians from the electrical power transmission and distribution industry, utilities and manufacturers
  • Technical managers and asset managers in the electrical power industry

The Advanced Power and Energy Centre (APEC) has been recently created at Khalifa University to help address the rapid and increasing change in the UAE’s electrical energy infrastructure. One of APEC’s key missions is to provide solutions for new challenges brought about by these changes, and to develop innovative ideas and solutions for optimizing and advancing future energy delivery. The Center covers a broad spectrum of pressing and important energy related issues including renewable energy integration, power electronics and conditioning, distribution and transmission system operation and high voltage engineering. The center capitalizes and builds upon the strength available at all three Khalifa University of Science and Technology (KUST) campuses with an overall main goal of becoming the R&D hub for power and energy innovation in UAE. The center has already received interest as well as financial commitment from key stakeholders (locally and internationally) including but not limited to Abu Dhabi Water and Electricity Authority (ADWEA), Dubai Electricity and Water Authority (DEWA), Getra (Italy), and Manitoba Hydro International (Canada). It will contribute to setting Khalifa University as one of the leading research driven universities in energy and equally important a catalyst for producing the next generation of engineers essential for addressing industry power and energy needs in the years to come.

Overview

The high voltage and dielectric materials(HVDM)research laboratory is the first of its kind in the UAE. It has been created to build expertise and research capability to address the challenges and technical problems facing current and future electrical energy installations. Vital high-voltage equipment operates under increasingly challenging conditions, with the requirement to provide a reliable power supply at high efficiency to a wide variety of industrial, commercial and domestic loads. Additional environmental constraints on high-voltage outdoor insulations systems call for the development of new dielectric materials that are able to perform more efficiently under diverse climatic conditions. Research at the HVDM lab aims to understand these issues and provide informed solutions for future operation of electric power equipment in electrical power systems and industrial installations. The high-voltage research group has been steadily expanding, with 4 faculty members, 3 researchers over the past two years, one lab engineer and several MSc students. The team members have proven experience in international universities, and active participation in international research and standardization bodies including CIGRE, CENELEC and BSi. With the new PhD program at KUST, it is expected that the lab will attract talented students to reinforce existing research and initiate new research projects.

We are currently working to create an accredited laboratory that will be classified as Approved Measurement System by the relevant international body. The availability of such a test facility will help establish one of the leading centers of excellence in research, as well as in the areas of testing and certification, advanced diagnosis of high voltage plant and advanced system modelling. It will also help in the creation of collaborative research projects. Additional benefits include improving asset management, increasing lifetime and usability of high-voltage equipment, optimization of power plant operation and better maintenance practice, in addition to developing a local skill set through graduate projects and targeted specialist courses. Several research projects have been completed or are currently running in collaboration with international partners, including the University of Tokyo, Utsunomia University and Kyushu Institute of Technology, Japan, Cardiff University, UK, IIT Madras, India, the University of Waterloo, Canada and Padova University, Italy.
