1 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 1 A test facility for distributed cogeneration: experiences on a microturbine and chiller based plant S. Banetta, S. Barsali University of Pisa, Italy Department of Electrical Systems and Automation

2 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 2 The cogeneration plant 45kW Microturbine 170kW absorption chiller/heater 330kW cooling tower Thermal (200kW) and electrical (50kW) load simulators Direct chiller connection to turbine exhaust

3 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 3 The cogeneration plant

4 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 4 The cogeneration plant

5 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 5 Plant scheme and monitoring

6 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 6 Cooling modeHeating mode Operation tests

7 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 7 Power balance Cooling modeHeating mode

8 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 8 Interface response 1 Load step

9 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 9 Interface response 2 Loss of mains

10 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 10 Interface response 3 Automatic reclosure

11 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 11 Remarks Low turboalternator efficiency, high losses High temperatures mean high thermal losses Fast interface response High sensitivity to grid disturbances Large impact of permitting procedure High cost of measuring and monitoring system

12 Stefano Barsali IT Academic Village Barcelona 12-15 May 2003 12 Future activity Set up of exhaust heat insulation Set up of a remote unit control system Development and testing of a biomass fired Stirling engine
