Asta
Veera
(29-30 July)
(4th of August)
Storms in Finland 2010
• 4 storms; Asta, Veera, Lahja and Sylvi
• 35,000 km of electric power network
were damaged.
• 9,000 distribution substations were
left without electricity.
Lahja
Sylvi
(7-8th August)
(8-9th August)
• Repair work nearly 200,000 hours
(over 120 man-years).
• Affecting about a third of Finland's
electricity network companies
• Led to long power cuts. The longest
individual power cuts lasted around
six weeks.

Communication network failures
during the 2010 storms:
• Asta: 1050pcs GSM and UMTS
Base stations, 38pcs TETRA Base
stations out of function
• Veera: 525pcs of GSM and UMTS
Base stations, 25pcs of TETRA
Base stations out of function
• Lahja and Sylvi:1072pcs of GSM
and UMTS Base stations out of
function.

BOETES VOOR STROOM EN GAS UITVAL
Risico Management door kennis van weersverwachtingen
De impact van het weer op de transmissie lijnen
▪ Weer ontregelt de transmissie van electriciteit
▪ Load forecasting : Krijg (be)grip op de weersverwachting
op kort en lang termijn
▪ Beïnvloed de inwinning van wind of zonne energie
Monitor de capaciteit van de distributie
▪ Fout analyse Verbetering van het distributienet

SMART GRID – COMMUNICATION NETWORK
Smart Grids and solutions
Need of more functions, more intelligence
•
Increasing amount of information requires high reliability and availability in wireless
communication networks
•
The communication network has to be reliable and safe
•
The communication networks has to survive extreme weather and environmental conditions
SMART GRID – COMMUNICATION NETWORK
Requiring higher availability and quality
More remote control and measurements
Cost efficiency
Remote operations, grid automation, shorter downtimes
