Abstract: The aim of this paper is to correlate the auxiliary power generation from an irrigation reservoir with the power generation of its upstream hydro power project in a cascade reservoir system. System considered for the study is the Pamba Basin- Kakkad Hydro Power Project and Maniyar Reservoir of Pamba Irrigation Project of Kerala State. In a water year from the 1 st June to 31st May, irrigation period spans for seven months from November to May in the Irrigation Project. As the water release of the upstream Hydro Electric Plant exceeds the irrigation demand, even during the peak irrigating months of January and February, it is hypothesized that there is surplus inflow for power production. A water year is divided to two Seasons namely Irrigation and Non-Irrigation seasons and rules are developed for both, based on the data of upstream Generation and Irrigation demand. A Fuzzy Rule model to simulate power generation using the surplus water is evolved and the outputs are compared with the real time data. In the Fuzzy Rule Based (FRB) model, the inputs considered are the Generation in units of the upstream Kakkad Hydro Electric Project, the Runoff of the catchment and the Irrigation Release. Spill from the barrage and the Power Generation in the downstream Carborandum Universal Madras India Ltd.’s – Small Hydro Electric Project (CUMI-SHEP) are considered as the outputs. The results obtained shows that the power generation from the FRB model are almost matching with the real time data.
