Jumping Water Method on Microhydro Power Plant for Water Channel

Abstract

Abstract-The most used renewable energy in Indonesia comes from hydro energy. The hydro energy available in Indonesia is around 75,000-76,000 MW. Of the total available water energy in Indonesia, there is only about 3.783MW to power for large-scale power plants and about 220 MW for small-scale power plants. One small-scale hydro energy source is a small river that has a water speed range of 0.01 M / s to 2.8 m/s. Although it only has a low water velocity, the energy stored in it has the potential power to generate electricity. There are three types of waterwheels based on the water flow system, namely: overshot, breast-shot, and under-shot. In the overshot mill, the water through the windmill and the mill are under the flow of water. Water twisted the mill and water fell to the lower surface. The mill moves clockwise. In the breast-shoot wheel, the mill is placed parallel to the flow of water so that water flows through the center of the mill. Water turns the mill counterclockwise. In the undershot mill, the position of the waterwheel is placed slightly upward and slightly touches the water. The flow of water that touches the windmill moves the mill so that it is anticlockwise. And in this final project the author made a new system called Jumping Water, this system works almost the same as the breast-shoot only the wheel is not in a lower condition of the water surface, the bottom position of waterwheel parallel to the bottom of the water channel, which distinguishes the jumping water position Can be altered altitude according to the flow of the water which will affect the speed of the spin mill.

Hydroelectric Power Plant Design with Hydraulic Pump System

“…and has the ability to spin to its best advantage In this instance, an overshot windmill was utilized. This kind of overshot wheel may be utilized in locations where there is enough height for the wheel to be spun by using the energy produced by the water that falls to the surface of the wheel, as opposed to flat areas where the wheel cannot spin (Syafriyudin & Firman, 2017). In comparison to other mills, this kind of mill is more energy-efficient to run.…”

Pengaruh Sudut Jumping Terhadap Aliran Air

“…Bentuk sudut jumping ini sangat berpengaruh terhadap pergerakan dan efisiensi air. Seperti pada prototipe jumping water microhydro dengan membuat sudut jumping dengan berbagai macam kemiringan [7]. Setiap perbandingan sudut kemiringan jumping water berpengaruh terhadap putaran kincir dengan menggunakan breastshot system water wheel sistem jenis ini sangat baik untuk meningkatkan kinerja air pada putaran kincir air.…”
