DESIGN AND FREQUENCY PERFORMANCE OF A MICROPROCESSOR BASED SPEED GOVERNOR
Öz
In this study,
closed loop and grid independent prototype of 750 W cross-flow turbine whose
cycle regulations are done by using adjustable wing mechanism is implemented.
Movement to an adjustable wing is performed by direct current motor which is
controlled by microcontroller by using screw shaft system and mechanical hand.
The frequency of the obtained voltage are controlled in function of that the
number of turns of the generator and of the turbine. For the control operation,
the voltage frequency obtained from the generator has been measured with the
zero crossing circuit and transferred to the microcontroller. With the setting
of the number of turns on the turbine, the value of the frequency of the 500 W
generator working in conjunction with the turbine is kept on desired levels.
These operations are realized by using a PIC16F877 microcontroller. Then,
frequency performance of the designed system is examined
