Abstract

One characteristic of developed countries is the need for energy is very much for all the needs of existing menyublay from large to small too. In this final project, power generation systems use water circulation. Where to drive a paddle wheel to rotate the generator will be the conversion of mechanical energy into electrical energy. By adjusting the valve on the pump motor is regulated through frequency response out of the generator. With the valve opens and closes itself automatically is driven by stepper motors, controlled by microcontroller ATmega 8535 with the PI metode. Regulated to control the frequency generator rounds using a PI controller, the set point minus the feedback signal can then enter the error produce microcontrollerPI. PI will issue a control signal to the valve, the valve should open a few degrees to rotate the paddle wheel and spin the wheel causing the generator to spin and release tension. Because of the frequency control is controlled through the generator rotational speed. This frequency output will be read by the sensor data as feedback frequency. From the feedback data will be offset against the set point and calculated by the PI controller. The result of calculation is a percentage of the control signal to adjust the opening and closing of valves, this process will run until the generator output is equal to the set point and continues to be maintained until a constant or in steady state Key words: voltage sensor, microcontroller ATmega 8535, PI controller, stepper motor drivers, lcd
