Background and Relevance for the Priority 6
SUSTDEV

• What is the problem to be solved?
• Improving existing HVDC technology for energy
  transmission/distribution
• Why it should be solved?
• To fully exploit advances in power converter and
  filtering technologies
• What are the benefits if it is solved?
• Increase energy transmission rate capability
  (efficiency of energy infrastructures)
• Reduced losses and costs for conversion
• Better energy quality and environmental
  compatibility
• Improved energy flow control
• Improved reliability and availability of the
  electric network.
• What needs to be achieved to solve the problem?
• New design and control strategies for power
  electronic converters
• Improve component and system reliability

ST STRATEGY

• Converters (DC-AC and AC-DC)
• losses (use of new power electronic technologies)
• accelerated ageing of insulation components (due
  to reduced commutation times)
• new design and control techniques
• to improve energy quality on ac and dc side,
• to avoid voltage inversion for energy
  dispatching,
• to reduce the impact on the degradation of
  insulation components
• MV-EHV and EHV-HV (MV) transformers
• losses (new design techniques),
• reliability of insulation system (evaluation and
  solutions for the effect of harmonics, including
  pulsed supply waveforms)
• AC and DC filters
• continuously tuned ac filters and active dc
  filters for the purpose of harmonic and reactive
  power control
• reliability, accelerated ageing of capacitors

ST STRATEGY

• Cables
• new materials (non-cross-linked, lower cost,
  better environmental compatibility)
• new manufacturing processes (allowing the use of
  new materials, like polypropylene or
  polyethylene-polypropylene blends)
• cheaper laying procedures
• increased performance and reliability (including
  accessories)
• Diagnostic systems
• mainly based, but not only, on partial discharge
  detection
• feasibility of on-line monitoring, cost,
• risk assessment,
• asset management.
• Economical evaluations
• comparing DC to AC solutions for the whole
  transmission systems,
• considering also the matter of line
  interconnection and distributed energy
  generation,
• environmental impact (recyclable materials,
  negligible electromagnetic compatibility effects,
  smaller extent of Right of Way.

WORK PLAN or JPA

• The project will be structured in five major work
  packages (WP).
• WP 1 Component design
• WP 2 Material and insulation model
  investigation
• WP3 Diagnostic systems
• WP 4 Reliability and economics of the whole
  transmission system
• WP 5 Dissemination
