Abstract
Screw turbine-type micro-hydro power plants are still controlled manually by humans when there is a change in
the electrical load on the generator output. If there is a change in the electrical load, the generator output voltage will
change, thus affecting the rotation of the turbine being used. In this case, humans are needed to manually regulate the flow
of water entering the turbine to maintain the stability of the generator output voltage by controlling the sluice gate. The
water discharge entering the screw turbine will rotate the generator through a belt/gearbox pulley transmission, thus
producing an electrical voltage at the generator output. To maintain the stability of the generator output voltage, it is
necessary to control the water discharge entering the screw turbine. The expected goal of this research is to design a control
system for a screw turbine type microhydro power plant to stabilize the generator output voltage and monitor the output of
a screw turbine type generator using a SCADA (Supervisory Control, and Data Aquisition) system. The method used is the
research and development method, namely the system design stage based on secondary data that has been collected, where
the system design includes hardware design and software design, followed by making hardware such as control panels and
devices. Software, which includes display design and leader diagrams and testing, is carried out by testing the system on
software, hardware, and overall system testing. From the results of the discussion and analysis, the screw turbine type
microhydro power plant control design system was created, a load control system consisting of 6 groups and sluice gate
opening control that uses an ultrasonic sensor to determine the water level. With the results of controlling the sluice gate at
a door opening of 30 mm, the generator voltage is 18.42 Volts DC, DC current is 0.0 Ampere at a load of 0 watts, when the
load is 30 watts the generator voltage decreases by 18.40 volts, current is 1.37 Ampere. Through the on-line monitoring
system, electrical parameters are obtained which are displayed on the SCADA system by looking in real-time at the history
of DC voltage and DC current, DC power, and DC energy generated by the screw turbine-type DC generator. The voltage
read is 18. 57 volts, current 1.37 Amperes, DC electrical power is 25.4 watts with a DC light load of 30 watts.
