ABSTRACT The availability of stable electrical energy is an important need, especially for regions that utilize renewable energy such as Micro Hydro Power Plants (PLTMH). PLTMH, which was built to support the learning process at Madrasah Jamiyah Al-Muawanah, Rantau Dedap Hamlet, South Sumatra, often faces the problem of voltage instability due to fluctuations in water discharge and load changes, which can damage electronic devices and disrupt Madrasah operations. This study aims to design and analyze the use of Automatic Voltage Regulator (AVR) as one of the alternative voltage regulation solutions in the PLTMH system. The research method was carried out by collecting data on mechanical and electrical parameters at the PLTMH site, including flow speed, water fall height, voltage, frequency, current, and power, using measuring instruments such as multimeters, tachometers, amperescent pliers, and flowatch. AVR planning is designed in two stages, namely a step-up AVR on the power plant side to increase the transmission voltage from 220 Volts to 250 Volts, and a step-down AVR on the consumer side to lower the voltage again from 250 Volts to 220 Volts. The result of adding an AVR system to the PLTMH can increase the voltage generated by the generator by 209,20 Volts, an increase of about 11.8%. The results of this planning are expected to improve the quality and stability of electrical voltage at PLTMH soas to support the sustainability of the renewable energy system.
