The use of induction generators for small-scale hydroelectric schemes in remote areas

The potential sites for small scale, stand-alone, i.e. not connected to the grid, hydroelectric power schemes, coincide quite closely with the locality of scattered rural villages and permits power to be generated near the end users at low transmission and distribution costs. Such schemes with power output less than 100 kW are usually referred to as micro hydro schemes. The present paper introduces the use of induction motors run as generators coupled to water turbines used for power generation in remote areas. Reference is made to pilot projects where successful schemes have been set up for a number of years now.
