  3. Agenda • Introduction • Purpose and objectives • Methods used • Communication media • Communication solutions in Fortum’s SCADA network • Results • Conclusions • Questions Diplomityöseminaari

  4. Introduction I – Starting point • Conducted for Fortum Oyj in Keilaniemi • The need for a common handbook in communication realization exists due to scattered company structure Diplomityöseminaari

  5. Introduction II • The power delivery system can be divided into 4 categories • Fortum’s SCADA system covers the MV Distribution network and Generation parts Diplomityöseminaari

  6. Introduction III – SCADA functions Diplomityöseminaari

  7. Introduction IV – SCADA elements Diplomityöseminaari

  8. Introduction V – Why SCADA? • Business around electricity distribution is strictly regulated and supervised by the Finnish Government • One way to improve the services and cost-effectiveness is to introduce a Supervisory Control and Data Acquisition (SCADA) system to the power delivery system • With proper SCADA systems we gain the benefits: • Disturbancies in electricity distribution come up faster • The fault location can be located faster • Electricy can be switched on faster • And everything can be supervised and controlled remotely from Control Center → There is a need for a proper communication network Diplomityöseminaari

  9. Agenda • Introduction • Purpose and objectives • Methods used • Communication media • Communication solutions in Fortum’s SCADA network • Results • Conclusions • Questions Diplomityöseminaari

  10. Purpose and objectives • The research questions: • What would the realization of communication links for new substations and disconnectors be? • What would the options in communication system upgrade be and how the solution candidates can be graded? • What would the financial aspects be? • The scope is limited to cover the communication technologies used in Fortum’s SCADA system - the last-mile connections to be exact Diplomityöseminaari

  11. Agenda • Introduction • Purpose and objectives • Methods used • Communication media • Communication solutions in Fortum’s SCADA network • Results • Conclusions • Questions Diplomityöseminaari

  12. Methods used • Literature analysis • Field study • CBA • SWOT Diplomityöseminaari

  16. Communication solutions I - Topology • 3 Tier approach • The scope in research is limited to Tier 2 and 3. Diplomityöseminaari

  17. Communication solutions II – Tier 1 • Packet data • Fully redundant Diplomityöseminaari

  18. Communication solutions III - Tier 2 • Serial comms • No redundancy Diplomityöseminaari

  21. Results - the CBA analysis Diplomityöseminaari

  22. Agenda • Introduction • Purpose and objectives • Methods used • Communication media • Communication solutions in Fortum’s SCADA network • Results • Conclusions • Questions Diplomityöseminaari

  23. Conclusions I • The research problem is approached by giving alternatives for the following cases: • Building a connection to a new substation or a switching station. • Building a connection to a disconnector station. • Replacing a connection to an existing substation or a switching station. • Replacing a connection to a disconnector station. • The recommendations are given on basis of the CBA and SWOT analysis Diplomityöseminaari

  24. Conclusions II • Building a connection to a new substation or a switching station. • OPGW (2128 €/a) • If own 110 kV network is built • If the need for extra capacity exists • Digital microwave link (8430 €/a) • If there is a mast nearby • If the need for the extra capacity exists • Optical fiber (29375 €/a) • If there is no mast nearby • If the excavation costs are moderate • If electrical grid is built underground and the same cable pit can be used for communication purposes. (In this case the cost for the communication would be 6174 €/a) • If the need for the extra capacity exists • Radio modem (696 €/a) • If there is no need for the extra capacity Diplomityöseminaari

  25. Conclusions III • Building a connection to a disconnector station. • Radio modem (696 €/a) • If a connection to the location can be established • Analog radio (921 €/a) • If for some reason there is no radio modem coverage available, but the coverage for analog radio exists • GSM (35 €/a) • If none of the previously mentioned alternatives is possible. This can be recommended only with high reservations Diplomityöseminaari

  26. Conclusions IV • Replacing a connection to an existing substation or a switching station. • Digital microwave link (8430 €/a) • If there is a mast nearby • If the need for the extra capacity exists • Optical fiber (29375 €/a) • If there is no mast nearby • If the excavation costs are moderate • If there is an absolute necessity for the extra capacity • Radio modem (696 €/a) • If there is no need for the extra capacity Diplomityöseminaari

  27. Conclusions V • Replacing a connection to a disconnector station. • Radio modem (696 €/a) • If a connection to the location can be established • Analog radio (921 €/a) • If for some reason there is no radio modem coverage available, but the coverage for analog radio exists • GSM (35 €/a) Diplomityöseminaari
