Francis turbines are one of the most widely used reaction turbines in hydroelectric power plants (HPPs) due to their high efficiency and ability to operate at varying heads and moderate discharge rates. However, in laboratory-scale installations, turbine performance can decline due to component damage and inaccurate measuring instruments. This study aims to repair a laboratory-scale Francis tur…
The Francis turbine is one of the most widely used reaction turbines in hydropower plants due to its high efficiency in converting water potential energy into mechanical energy. However, turbine efficiency can decrease due to component damage and suboptimal valve opening settings. Such conditions occurred in the laboratory-scale Francis turbine at Sriwijaya University, making system repairs and…
Many villages in Indonesia still face limited access to electricity due to geographical conditions and low income levels. The use of pico-scale crossflow turbines is one of the right alternatives to increase the electrification ratio in remote or rural areas. Crossflow turbines are considered economical, because of their simple design, relatively low installation costs, and have the ability to …
The study designed the crossflow water turbine runner by using material paralon (PVC), which compare variation in the angle of inlet runner 20 °, 30 °, 40 ° to get maximum efficiency. This testing using test equipment the laboratory or micro hydro power plant PLTMH to utilize renewable energy sourced from water capacity 7 litres per second with the source water from a pump with water velocit…
The province of South Sumatra has a total area of approximately 87,017.42 km2 and lies between 1º - 4º south latitude, 102º - 106º East Longitude. South Sumatra, known as aquatic area, has large rivers with abundant water resources, these water resources are sourced from 9 major major rivers, the Musi River, and other rivers. (Kadin Indonesia, 2011). Turbine is a tool used to convert an ene…
The potential of renewable energy in Indonesia is so abundant that it is profitable and as a provision in realizing national energy security. However, the lack of use of NRE for electricity is due to the high production price of EBT-based power plants, making it difficult to compete with power generation, especially coal. There are solutions in overcoming the problems in the development of the …
Energy is an element obtained from natural resources and used to meet all the needs of living things, especially humans in their daily lives. Existing energy sources are reduced, especially fossil-based energy such as coal and oil. To overcome this, it is necessary to diversify and conserve energy. The use of pico hydro turbines with energy from water flowing in clean water supply pipes as an e…
There are many things that need to be considered in the Turgo turbine blade printing process, starting from determining the boundary conditions is used to determine the value of .value is used to get value. The relative speed of water discharge is used to determine the absolute velocity value of the water discharge blade, the angle value of obtained from the slope angle minus, and the value of …
