specialized in mission critical wireless data communication systems • • • • • Widest selection of products in its field Worldwide distribution network Engineering and project management Installation, commissioning and maintenance services Complete tailored data communication solutions and systems for telemetry communication need specialized in mission critical wireless data communication systems 30 000 Pcs per year 300 000 pcs in operation INHOUD • • • • • • • • • OVERZICHT VAN HET GRID PROBLEMEN MET PUBLIEKE NETWERKEN GELDBESPARING DOOR: BEHEERSING VAN AFGELEGEN LOKATIES RISICO MANAGEMENT DOOR WEER OBSERVATIE SMART GRID EISEN SMART GRID PROTOCOLS DRAADLOZE DATACOMMUNICATIE BESCOM PROJECT, INDIA BEHEER EN MONITORING VAN HET GRID DUTCH NETWORK MANAGERS OF GAS AND ELECTRICITY VOORZIET ‘REGIONAL ROAMING’ IN DATA VERKEERSVOLUME AFHANKELIJKHEID VAN PUBLIEKE MOBIELE DATA NETWERKEN DATA ENCRYPTIE IS ONONTKOOMBAAR CONGESTIE OP 2,4 GHZ BAND NADELEN VAN EEN 5 GHZ NETWERK? Beperkte afstand tov 2,4 GHz Ondersteuning van bestaande Wi Fi apparatuur Obstakels (betonnen muur) is een serieuze belemmering van het signaal 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. 12 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. 13 Risk Management bij distributie van electriciteit en gas 15 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 17 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 Reliability Redundancy POWER SYSTEM MONITORING – NARROW BAND COMMUNICATION NETWORK IEC 60870-5-101 Cost efficiency Remote operations, grid automatio, shorter downtimes POWER SYSTEM MONITORING – NARROW BAND COMMUNICATION NETWORK DNP 3.0 Distributed Network Protocol Cost efficiency Remote operations, grid automatio, shorter downtimes Solution: NARROW BAND RADIO IEC-101 22 Solution: NARROW BAND RADIO IEC-101 and 104 23 Solution: NARROW BAND RADIO DNP IP/DNP 3.0 24 Draadloze datacommunicatie 3rd party offered service Private networks subscription Narrowband radio modems cellural 4G Microwave W C D M A 3G 2G Satellite VSAT Fiber Optic (or copper) cables 25 STUDY: Radio modem networks vs. GPRS Independent IP-based radio network for transferring weather data [Aalto University School of electrical engineering, Department of Communications and Networking MSc.
