1 Frankfurt am Main (Germany), June 6-9, 2011 Design and Implementation of an Innovative Telecontrol System in the Vattenfall Medium- Voltage Distribution Grid Frankfurt am Main (Germany), June 7, 2011 Dipl.-Ing. Mark Geschwindner, Vattenfall Europe Distribution Hamburg GmbH

2 Frankfurt am Main (Germany), June 6-9, 2011  Berlin, Hamburg - centres of German politics and economy  Increased customer expectations on reliability of power supply  2012 Introduction of quality regulation in Germany  meeting challenges by telecontrol of substations to reduce CAIDI (MV)  components: EU-conform tendering procedure / manufacturer independency  creation of an universally applicable retrofit solution for existing substations GESCHWINDNER– DE– S3– 0568 Introduction, Project Motivation Hamburg Berlin

3 Frankfurt am Main (Germany), June 6-9, 2011 Scheme of Telecontrol System TETRA modem DSL modem IEC over V24/PPP over ethernet alternative 1 alternative 2 ▼ M M motor contoller standard process interface module central control centre system … … concentrator UPS module tele- control module indicators commands/feedback uninterruptible power supply Communication module -101 (1) (2) (3) (1) (2) (3) IEC GESCHWINDNER– DE– S3– 0568 TETRA net TC- cable net secondary technical components primary technical components existing secondary network infrastructure Central secondary technical components and SCADA system -101

4 Frankfurt am Main (Germany), June 6-9, 2011  new substation will be equipped for moderate costs  retrofit kits only available for switchgears younger than 1995  for ~50% of the substations retrofit kits not offered by OEM  limited free space in compact substations requires innovative design  cooperation with Linak-UK Ltd.  development of an independent adaptive motor drive system Primary Technical Components Bilder TC module | UPS module flexible shafts terminal box source: Linak-UK Ltd. GESCHWINDNER– DE– S3– 0568 motor box gearbox (switch adaptor)

5 Frankfurt am Main (Germany), June 6-9, 2011  compact modular design and defined interfaces  combination of components from different manufacturers possible  PowerCaps used for UPS module with technical service life of more than 15 years  UPS module allows an independent operating time of ~90 minutes  communication: IEC  TC module: integration of TETRA or SHDSL modems possible UPS, Telecontrol, Communication Module GESCHWINDNER– DE– S3– 0568 UPS module | TC module DSL modem TETRA modem

6 Frankfurt am Main (Germany), June 6-9, 2011  use of Vattenfall owned existing TC cable net (DSL) and TETRA net  all system components must be independent on public power supply  TCP/IP connection: concentrator were adapted to the specific requirements of TETRA  concentrators contain firewall functions by protocol conversion  scalable in steps of 200 substations System Configuration up to SCADA System GESCHWINDNER– DE– S3– 0568 SCADA network control operator terminals -Netz LAN switch Concentrator -101 firewall DSL over TC- cable dig net … -104 … TETRA net

7 Frankfurt am Main (Germany), June 6-9, 2011 Innovative Antenna Solutions  20 base stations are currently in use in Berlin and 16 in Hamburg  radio base station covers a radius of approx km  locations of substations are often not optimal from HF-technical view  inconspicuous design to prevent from vandalism and manipulation GESCHWINDNER– DE– S3– 0568 roof antenna w/o GRP cover pole antenna door sign antenna

8 Frankfurt am Main (Germany), June 6-9, 2011  Predicted reduction of CAIDI (MV) of more than 50 % is achieved  high technical efforts for development of technical components in cooperation with industry partners  Positive customer response regarding outage time reduction  Positive experiences motivate for further investments in this new technology Conclusions CAIDI min amount of completion GESCHWINDNER– DE– S3– % 100% 5% % 50% 100% CAIDI degree of completion with telecontrolled substations CAIDI shortening of a transformer area
