Implementation of IEC61850, in a conventional substation control system (English)
Abstract [sv]

Examensarbete i Elektronik och datorteknik utfördes på teknikavdelningen vid ABB Substations, Västerås.  Syftet med arbetet är att teoretiskt illustrera skillnaden mellan konventionella och numeriska kontrollsystem för substationer. Kontrollsystemen är vitala delar i substationer som styr, övervakar och skyddar anläggningens kopplingsutrustning och skyddar mot skador på egendom och människor.

Konventionella kontrollsystem kräver mycket material och konsumerar onödigt på jordens naturresurser. I konventionella kontrollsystem sker allt signalutbyte och kommunikation mellan utrustningar i anläggningarna via kopparkablar. Alla manöversignaler skickas via koppartråd mellan manövertavlor och apparater. Kopparkablar isolerat med olika isolationsmaterial, förläggs i kabalkanaler och kabelstegar. Kontrollutrustning byggs i apparatskåp.

Man kan minska miljöpåverkan genom att används IEC61850-teknik och fiberoptiska kablar för kommunikation och signalutbyte. Det reducerar konsumtionen av naturens tillgångar och miljöpåverkan. IEC61850 är ett standardprotokoll för automationsystem i anläggningar och är kompatibelt för produkter mellan de flesta tillverkarna av kontrollutrustning. Numeriska kontrollsystem har enkelt åtkomst till stationsdata och kan upprätta statistik för att analysera och förstå systemet karaktär och därmed underlätta planering av underhåll och uppgradering av systemet.

Abstract [en]

This bachelor thesis in Electronic and computer engineering is performed at ABB Substations Engineering department. Purpose of the thesis is to illustrate theoretically differences between conventional and numerical control systems for substation. Control system is vital part of substation which control, monitor and protect substations equipment hence protect against damage to property and human beings.

Conventional control system consume lots of material and have huge impact on environment and has more risk for fire, toxic gases, and explosions. All operations and signal exchange in conventional control system is through copper cables which are isolated with different isolation materials and to be laid in cable trenches, on cable ladders. It needs metal case cubicles to install and manage different components. Manufacturing and transportation of all material consume resources from nature.

The footprints can be reduced dramatically by implementing IEC61850 to conventional control system and using fiber optics cables for communication and signal exchange. This reduces the consumption of natural resources. It can even decrease or eliminate the dependency of particular manufacturer of control equipment or components. IEC61850 is a standard protocol which is compatible with all major control equipment, manufactured by different companies and have high interoperability. Numerical control systems have easy access to data and statistics which help to understand nature of system hence planning maintenance and upgrading of system.
