Objective
Project aims to demonstrate the possibility of using electronically controlled self-excitation techniques in order to reduce the connection transients of induction generators in regions with weak electrical grids. The system will also permit automatic power factor correction, improved voltage regulation at the end of long spur lines and the possibility of isolated operation when using conventional induction generators. The expected plant capacity is 55 kW with a net head of 2.1 m and rated flow of 4.0 cumecs. The control systems are particularly relevant for developing countries.
The project is fully operational and clearly demonstrates the advantages of a fully automated control system. The grid-connection transients have been considerably reduced in comparison to conventional systems. The system has a maximum rated capacity of 55 kW.
This project proposed to develop a 55 kW run-of-river scheme with a softly connected cage induction generator. The cage induction generator will be self-excited by an appropriate capacitor bank, the voltage and frequency will then be stabilised by an electronic governor and matched to that of the grid, and finally, the generator will be synchronised to the grid in an almost transient-free manner. Power factor control can also be implemented in a safe manner.
The Project aims to demonstrate the suitability of these schemes for small hydro installations of up to 1 MW size in regions with weak grids.
