Abstract

Micro Hydro Power Plant is a power plant that utilizes low-head hydropower to produce electrical energy. The problem is the unstable rotation of the generator caused by changes in water flow, resulting in changes in generator efficiency that affect the quality of electricity distribution. Therefore, in this study, a flywheel is used to determine its effect on generator efficiency. This study uses a water turbine as a generator drive. The flow of water falls into the turbine through pipes equipped with valves. The head and water flow are kept constant by adjusting the valve opening. The generator is a 3-phase generator, 220 V (Y)/ 380 V (Δ), 4 Pole. The flywheel weight is 0.5 kg, 2 kg, 2.2 kg, and 3 kg. The measuring instrument is a wattmeter to measure the electrical power output, a torque meter to measure torque and a tachometer to measure the generator's rotational speed. The torque and shaft rotation is used to calculate the mechanical power supplied to the generator. The largest generator efficiency is at a flywheel weight of 0.5 kg. The smallest efficiency is at a flywheel weight of 2.2 kg.
