  1. Communication in Substations:IEC618502.4 : CONCLUSION Sudhakar RAMPURKAR / AnshumanBHALLA 26th & 27th October 2009

  2. Conclusions • For a real benefit, one needs both technical progress and international agreement to achieve the seamless communication architecture. • This is exactly what IEC 61850 offers:

  3. Summary • IEC 61850 is now being used • Users’ benefits are: • Better planning in Open Electricity Market • Streamlined Specification • Simplified Design • Faster System Configuration • Securer Operation & simpler Maintenance • Safeguarded Investment • Various migration paths are available

  4. Summary • One standardised communication for all needs in the substation • Fully supports all substation automation functions comprising control, protection and monitoring • Is a global standard and the key to interoperable solutions • Architecture is future proof and facilitates future extensions, therefore it safeguards investments • Ability to reuse typical functions and/or bay designs vendor independent

  5. Summary, cont. I • Defines the availability requirements, environmental conditions and the auxiliary services of the system • Specifies the engineering process and its supporting tools, system life cycle and the quality assurance requirements • Provides engineering and maintenance support by means of the substation configuration language based on XML, i.e. documentation included • Vendor-independent engineering-data exchange

  6. Summary, cont. II • States the conformance tests to be carried out on the products • Flexibility allows optimisation of system architectures (scalable technology) • Uses commercially available hardened communication components (Industrial Ethernet) • Common use of infrastructure

  7. Market demand: Systems sales / Segmentation • IEC 61850 has become a strong requirement for Substation Automation Systems, approx. 40% • Transmission: 60% (main exceptions: US, China) • Distribution: 20% growing (linked to the IED price) • Rail: 10% growing (Europe, India starting) • Industry/ Oil & Gas: rare

  8. Market demand: Regional Strongest demand in: • India • Brazil • Central & South America • China • Middle East • Europe – various countries

  9. IEC61850 from Project Perspective • IEC61850 is very large with many service models and optional features • End users implement different combinations of these service models and the different features they provide • The protocol is still being evolved • Insufficient to simply specify IEC61850 • Necessary to state: • What features are to be used • What performance is required • Requires detailed analysis and comparison of all products in the project to ensure a good fit

  10. IEC61850 at Tendering stage • A sample of important device specifications: • Quantity of client/server associations to each IED • Quantity of peer-peer messages the device will publish • Quantity of peer-peer messages the device will subscribe to • Number of characters allowed in the device name • Service models required • Control models to be used • Implemented Logical Nodes & Optional Data Objects/Attributes • Implemented TISSUES • Where can this information be found? • Device Documentation • Substation Configuration Language Files

  11. Motivation for use of IEC61850 • Utilities expect • Interoperability of: • functions • devices • uniform system handling • harmonised general system properties • To Reduce Engineering Costs by: • Standardised information exchanges between tools • Reduction of manual entry & associated errors • Reuse of project information & configuration
