The increased use of wind-driven generators in the last few years has
resulted in special generator designs which ope):ate at varying speed and
frequency, utilising static inverters for conversion of direct to alternating
current. The potential application of this emerging technology to
hydropower production schemes has recently received considerable attention,
as witnessed, for example,by the recent DOE-EPRI (1983) workshop on applications
of variable-speed generators in hydropower. Typically, a variable speed
hydroelectric scheme would consist essentially of the turbine, a
synchronous generator (variable speed and frequency), a rectifier for the
generator output, an inverter at the powerhouse and alternating current
transmission, or direct current transmission, and an inverter at the substation..
Regardless of the speed variations, the inverters have the
ability to maintain virtually constant frequency and voltage for any given
