A combined method using statistical and numerical models has been developed by authors for selecting a pump running as turbine (PAT) to be applied in micro hydro plants. The data of the site (head and capacity) allow to calculate two coefficients, CQ and CH, which identify the pump to use successfully as turbine in that place. A one dimensional model, starting from data available on the pumps manufacturers catalogues, reconstructs a virtual geometry of the PAT, then calculates the performances curves, head vs. capacity, efficiency vs. capacity. The case study of the Calabrian site of Sersale (Italy), shows a good application of the proposed method and the estimate of the annual energy yield gives a confirmation of the effectiveness and convenience of PATs.

Abstract
A combined method using statistical and numerical models has been developed by authors for selecting a pump running as turbine (PAT) to be applied in micro hydro plants. The data of the site (head and capacity) allow to calculate two coefficients, CQ and CH, which identify the pump to use successfully as turbine in that place. A one dimensional model, starting from data available on the pumps manufacturers catalogues, reconstructs a virtual geometry of the PAT, then calculates the performances curves, head vs. capacity, efficiency vs. capacity. The case study of the Calabrian site of Sersale (Italy), shows a good application of the proposed method and the estimate of the annual energy yield gives a confirmation of the effectiveness and convenience of PATs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
