Perbaikan Kualitas Daya Pada Pembangkit Listrik Tenaga Mikro Hidro Menggunakan Improvement Power Control For Generator

Micro Hydro Power Plant (PLTMH) is a type of small scale power plant that uses water energy by converting the potential energy of water into mechanical work to produce electrical energy. PLTMH usually has a smaller capacity compared to large-scale power plants. In general, PLTMH is widely used to supply electricity in remote areas that are difficult to reach by the main electricity network, therefore PLTMH is usually only equipped with a simple control system.
The problem with the PLTMH control system is that it is not able to optimally anticipate changes in mechanical power and load. Because in principle, the frequency and output voltage of the PLTMH depend on the mechanical power of the falling water and the load connected to the PLTMH. It is changes in load that cause frequency and voltage instability. Frequency stability in PLTMH is generally controlled with an Electronic Load Controller (ELC) device. Meanwhile, the output voltage is controlled with Var control as reactive power compensation. Therefore, the explanation of this PLTMH problem is to design and implement an Improvement Power Control For Generator (IMPOSTER) scheme with a combination of ELC and Var control systems to maintain frequency values, power factor values and voltage in the PLTMH system.
