This paper describes inves t igat ions ca r r i ed out t o es tab l i sh a design concept fo r a 1 kW wind-powered generator s u i t a b l e f o r use a s an a l t e r n a t i v e power source i n i so la ted locations. Design c r i t e r i a include high power t o weight r a t i o , s impl ic i ty of assembly and p o t e n t i a l f o r f ixed, mobile o r por table app1.ication.s. The repor t proposes a s u i t a b l e configurat ion using a Darrieus S t ra igh t blade r o t o r with a microprocessor based control system and provides information on t h e power output t o be expected i n d i f f e r e n t wind environments.

Accordingly thc p l a n should include:-
(a) evaluation of turbine s t r uc tu r a l performance
(b) evaluation of turbine aerodynamic performance
(c) development and t e s t of spo i le r u n i t s
(d) evaluation of a l t e rna to r performance
(e) optimisation and evaluation of e l e c t r i c a l control
(f) 'development and t e s t of t he guyed tubular tower
Once these i n i t i a l object ives have been achieved, it i s des i rable t h a t t he wind- powered generator be deployed i n t he f i e l d for an extended period f o r evaluation of overal l performance.
