Abstract：An inherently self-regulated class of resistance-load generation schemes，generator input power can be made to vary with speed in a manner which should enable the windmill to operate at near optimum tip speed ratio over a wide range of wind speeds, The small windmill application in which the output is connected to a constant-resistance load and the field is connected in plain shunt or series. It is shown that，with this configuration，a fairly good natural match can be obtained between the power/speed characteristics of the windmill. Test results are included and indicate that an external d.c. source would often be necessary to initiate build-up in a practical system.
