Abstract

Utilization of Micro Hydro Power Plant at the Gunung Halu case study type run-off the river is a household use only in the afternoon, around 5 pm until bedtime at about 10 pm. Therefore, more than 75% of the energy is lost. This case study lost power which can be used as a by-product, such as for drying coffee beans. In this case study, a design was carried out to obtain by-products and improve power quality in the electrical system. In addition, they complain about the poor quality of power controlled by frequency using Triac-Based Electronic Dummy Load Control. The heat from the dummy load in the case study is used as a by-product. MHP with a minimum power of 20 kW, and the usage time of customer service is about 6 h. The energy for the by-products is about 360 kWh/day, and the power quality improved by using Triac-Based Electronic Load Control and Hysteresis Current Control for the active filter. As a result, the power factor is close to one, the generator current harmonics is less than 2%, and the voltage harmonics is less than 5%.
