Objective
- Increase the sampling on the geothermal energy
- Obtain significant savings in the network operating cost
- Remove the heavy fuel oil N°2
- Develop design and network control techniques
- Identify the characteristics of the installation acting as a base for the process control and checking systems
- Control network performance and operation in real time using computer applications
- Demonstrate the areas for improving the operation of networks powered by geothermal energy.
- Increased geothermal coverage from 80 to 95% in average year, i.e. a gain of about 9000 MWh
- Transfer of 1000 T of heavy fuel oil to geothermal energy
- Electricity savings estimated at 800 MWh/year.
1.STUDIES:
- complete survey of needs and inventory of installations,
- definition of the characteristic curves * temperature hierarchy
* network power
* daily consumption
* diagram of average yearly consumption
- detailed examination of the network hydraulic diagram,
- update of the diagrams in substations. Design of installations and use of equipment according to maximum sampling on the geothermal energy,
- definition of the network characteristics,
- checking of equipment in stations,
- accurate calculation of hydraulic balancing,
- checking and calculation of dimensions and correct operation of the control valves.
2. WORK:
- Interventions on the networks : depending on the reutilisation of the network hydraulic diagram; modification or replacement of sections of piping.
- Interventions in substation : Modification of substations, depending on the results of the studies. Modification or replacement of certain balancing devices for improved control accuracy. Modification or replacement of certain regulations for improved control on flow rates and temperatures.
- Adaptation in station : Adaptation of equipment. Correction of regulations.
- Settings-tests : This phase will take place over an entire winter in order to be able to test the reactions of the installations and evaluate the performance.
