Heggala (12.21040°N, 75.8114°E) a remote village hamlet located in Coorg district of Karnataka is deprived of electrical power supply from the power grid. It receives an annual rainfall of nearly 2055 mm and a solar irradiation of around 56.5 kW/m2. The sunlight in unison with continuous rainfall (which ensures consistent flow in the streams having a discharge of 5–6 L/s) can be optimally utilized for the generation of power. The peak demand of about 800 watts can be fulfilled by a 1 kW Micro-grid system. The Hydro power can contribute to nearly 60% of the demand and the remaining part can be complemented by Solar PV system to ensure uninterrupted power supply to the houses in the village. A thorough technical analysis pertaining to catchment area, flow, rainfall, and solar irradiation have been studied and a design of 1 kW micro-grid system is accomplished. Further, a compact and suitable turbine has been selected and proposed to be installed at the appropriate location for the generation of Hydro power.

摘要

Heggala (12.21040°N, 75.8114°E) a remote village hamlet located in Coorg district of Karnataka is deprived of electrical power supply from the power grid. It receives an annual rainfall of nearly 2055 mm and a solar irradiation of around 56.5 kW/m2. The sunlight in unison with continuous rainfall (which ensures consistent flow in the streams having a discharge of 5–6 L/s) can be optimally utilized for the generation of power. The peak demand of about 800 watts can be fulfilled by a 1 kW Micro-grid system. The Hydro power can contribute to nearly 60% of the demand and the remaining part can be complemented by Solar PV system to ensure uninterrupted power supply to the houses in the village. A thorough technical analysis pertaining to catchment area, flow, rainfall, and solar irradiation have been studied and a design of 1 kW micro-grid system is accomplished.
