iec 61850 motivation
IEC 61850 – Motivation

Substation automation:

  • Applications must deal with numerous protocols, data formats and data addressing
      • Limited interoperability
      • High integration costs
      • High maintenance costs

Something needed to change:

 IEC 61850 standard creation

iec 61850 key differentiators success factors
IEC 61850 – Key differentiators / Success factors
  • Integrated approach to system design and communications
  • Technical innovations:
    • File based setup: archiving, maintenance and repeatability
    • Unified modeling: of functions and common dictionary of terms
    • Self description devices
    • Independence of underlying protocols – future proof
  •  Market support from vendors

proposed power quality enhancements
Proposed Power Quality Enhancements
  • Adoption of IEC 61000-4-30 and EN50160 as PQ enhancements for IEC 61850 standard:
    • Vendor neutrality
    • Application relevance
    • Global market presence
  • Both standards are well established globally and go hand in hand to provide contractual-based PQ measurement support (4-30) and compliance reporting (EN50160)

conclusions
Conclusions
  • IEC 61850 is a powerful standard with global support in the industry and many technical qualities to support engineering workflows in the design, maintenance and operation of modern electrical infrastructure.
  • Using global power quality standards IEC 61850 can be enhanced to provide key support for advanced power quality applications by:
    • Improving logical node support,
    • Improving time synchronization, and
    • Utilizing file based reporting options.
