Overview & Events

Project description, task information, and event opportunities

Engineers, designers, and managers of underground transmission can use the tools and methods developed in this project to effectively apply, operate, and maintain HVDC transmission cable technologies. Utility engineers may use the improved understanding of the HVDC cable systems to achieve effective and economical system designs and determine system ratings. Maintenance departments can deploy new fault location methods and tools to locate faults more efficiently, especially for long distance HVDC cables.

Approach

This project investigates and develops methods and tools for effective applications of HVDC cable technologies for system integration and interconnection:

  • Investigate and evaluate design tools for utility engineers to prepare feasibility studies and verify proposals and implementations.
  • Evaluate cable insulation materials and aging characteristics to optimize designs and extend the life of HVDC cable systems.
  • Evaluate operational practices in application of HVDC cable technologies, based on technical and economic benefits and increased power transfer capability requirements.
  • Evaluate condition assessment, maintenance, inspection, and fault location technologies to meet operation and maintenance requirements.

Research Value

This research produces new understanding, methods, and tools that can assist engineers and designers in applying, operating, and maintaining HVDC transmission cable systems as well as extend asset life and prevent unexpected outages. For example:

  • The use of the reference books, design tools, and other investigative results may lead to more effective designs and applications for power grid integration and interconnection.
  • Effective inspection and monitoring of assets could lead to increased asset utilization, rapid maintenance intervention, improved reliability, and reduced repair costs.
  • Better understanding of failure mechanisms and prevention procedures may result in longer asset life, reduced customer outages, and lower operating costs.
