Technical innovations in the district heating system in Odense Generally about Fjernvarme Fyn A/S GIS Modelling of district heating networks Metering Peer Andersen, Fjernvarme Fyn A/S District heating workshop Visegrad 2012, november 5-6.
Generally about Fjernvarme Fyn A/S Side 2 Fjernvarme Fyn A/S is owned by the municipalities of Odense (97 %) and Nordfyn (3 %). Fjernvarme Fyn A/S is managed by a board of directors selected by the town council and members selected by the employees Number of employees: 94 Fjernvarme Fyn A/S is a DH distribution company with 100 % heat production capacity in peak and reserve load boiler facilities.

GIS based on ESRI ArcGIS software packet All information on components and pipes is stored in the GIS
All data on the network in one place with acces for all employees
Designing of network Signal cable database Consumption database Interface to modelling in TERMIS Maps Pipe and components data Information Decision-making Mobil GIS WEB GIS GIS for all LER
Hydraulic and thermal modelling of the network Fjernvarme Fyn A/S use TERMIS software for hydraulic and thermal modelling Models are build from GIS data (pipes, consumers) Network models used for: design of network What if scenario calculations, planning Operation monitoring with realtime simulation models (intergration with SCADA system) Optimazation of suply temperature Pump optimazation
Supply temperature from central Supply temperature at consumer Temperature optimization. Target Temperature optimization Purpose: To reduce energy consumption (heat loss and pumping energy)
The model simulate the operation for the next 12 hours based on load forecast The software find the optimal supply temperature to minimize costs of heat loss and pumping energy. To bee able to deliver the heat to the consumers at the time they nead it, it is necesarry to compensate for transportation delay between central and consumer. The load forecast tool use weather forecast data (temperature and windspeed) from Danish Meteorological Institute, and historical load data from the SCADA system Temperature optimization. Load forecast
Roules Restrictions Media velocity < 2 m/s Max pressure < 60 mVS Max pressure difference : 3,5 bar Min pressure difference : 0,5 bar Temperature in distribution pipes> 60 °C
In the DH system of Fjernvarme Fyn A/S the optimal supply temperature is the lowest possible that meets, either: 1. the required minimum temperature of 60 degrees C in the distribution pipes in all parts of the network (summer and transition periods), or 2. the demand for heat in cold periods without exeeding the pressure limits in the pipes and pumping capacity. By the end of 2012 temperature optimazation has been impelented in all supply zones. The reduction of heat loss is approximately 10 %. Temperature optimization. Load forecast
Customer Consumption Impact Individual metering. Incentive to save energy. Visualization of consumption Easy access Behavioral effects. Intelligent service. Benchmarking of consumption
Fjernvarme Fyn – Metering platform 2012 Third-largest district heating company in Denmark in energy sales but largest in network and number of customers: metering points km distribution pipes All electronic heat meters of the ultrasonic type Mobile Radio Network system Tests and considerations Return of investments Readings so far performed by the municipal sanitation service twice a month Prepared for next generation AMR
Mobile Data Transceiver – what is it? One box for mounting in vehicles. It contains 2 components: A GSM modem which every night transmits data from the mobile RF Concentrator A Mobile RF Concentrator which during driving picks up meter data
Mobile Data Transceiver – Features based on demand. Reads out the following data: Monthly data: – date/hour, Energy, Volume Actual data: – date/hour, Energy, Volume – Info-codes, Hour counter – Energy (flow), Energy (return) Automatic surveillance and adjustment of the internal watch when passing by. Co-functions with existing RF network.
Mobile Network System features System features: Few system components High read out success rate > 98 % No operational staff necessary No predefined routes Automatic meter registration Reading via standard radio protocol Short meter reading time frame
