“…The connection cable to be selected for this system must have a current carrying capacity of at least 58 A. Equation (8) should be used to calculate the cable cross section. s = 0.0175 * 2 * l * P/ f k * U 2 (8) In Equation 8, s is cable cross-sectional area (mm 2 ), f k is conductor loss (%), l is cable length (m), P is power (W), U is system voltage (V) and a specific coefficient of 0.0175 for copper (Ω.mm 2 /m).…”

“…Hydrokinetic turbines have very similar design and theoretical background to wind and hydrodynamic conversions such that all of those systems offer clean energy with a low environmental effect [5,6]. Most of the recent studies were intend to increase the efficiency of hydrokinetic machines in terms of power coefficient and hydro dynamical properties by avoiding system losses [7,8].…”

In this study, a hydrokinetic turbine is designed for the high-altitude regions where local electricity network lines are difficult to reach. If there was a stream flow around, electricity production could be possible and necessary because of environmental reasons. The performance of the hydrokinetic turbine was investigated experimentally and numerically. The numerical analyses of the turbine system were performed via MATLAB/Simulink version R2014a. Except power-based performance characteristics, efficiency of the system in terms of installation and necessary investment costs were also investigated. It is calculated that the system to be established on a river with a water flow rate of 30 m3/h will meet the investment cost in approximately 8 years.

“…In line with the increase in the electrification ratio target to 100% by 2025, the electricity demand is projected to increase more than 7 times to 1,611 TWh in 2050. To meet this electricity demand the government has made a 35 GW program which has been confirmed in the Medium Term Development Plan document National (RPJMN) 2015 to 2019 [1]. When this program was launched, there was a slowdown in achievement due to economic and technical factors, such as the characteristics of each type of power plant project.…”

The need for electrical energy in Indonesia continues to increase every year. In line with the increase in the electrification ratio to 100% in 2050, the demand for electrical energy is projected to reach 7 times, namely 1,611 TWh. To meet electricity needs, the government has created a 35 GW program, but one of the largest contributors to power generation fuel is coal with a share of 58% or around 50 GW which is estimated to be exhausted within the next 68 years. For this reason, innovations are needed in terms of fulfilling electrical energy by utilizing renewable energy potential, one of which is hydro energy, which is 45,379 MW from a total resource of 75,091 MW. Therefore, from this potential, innovations related to renewable energy have been created, namely the Hybrid Portable Underwater Turbine Hydro and Solar Energy hybrid power plant. This power plant uses an undersea current as a propulsion which is hybridized with solar power to increase the production of electrical energy. This power plant has the advantage that there is an Underwater turbine design that is resistant to underwater flow and a water flow direction to increase the work efficiency of the underwater turbine. From the test results, the portable Underwater turbine hydro produces 950 W in a day. Solar panels produce 65.6 Watts a day. The total hybrid that can be produced is 1.02 kW a day. In its implementation it can supply loads of up to 900 (VA) such as lamps, fans, TV, etc. This hybrid power plant can be a solution to help meet electricity needs in the area around Dusun Dongol, Sidoarjo through alternative electrical energy innovations.

Performance Characteristics in Runner of an Impulse Water Turbine with Splitter Blade

The impulse water turbine is a promising energy conversion device that can be used as mechanical power or a micro hydro generator, and its application can effectively ease the current energy crisis. This paper aims to clarify the mechanism of liquid acting on runner blades, the hydraulic performance, and energy conversion characteristics in the runner domain of an impulse water turbine with a splitter blade by using experimental tests and numerical simulations. The runner was divided into seven areas along the flow direction, and the power variation in the runner domain was analyzed to reflect its energy conversion characteristics. The obtained results indicate that the critical area of the runner for doing the work is in the front half of the blades, while the rear area of the blades does relatively little work and even consumes the mechanical energy of the runner to produce negative work. The high energy area is concentrated in the flow passage facing the nozzle. The energy is gradually evenly distributed from the runner inlet to the runner outlet, and the negative energy caused by flow separation with high probability is gradually reduced. The clarification of the energy conversion performance is of great significance to improve the design of impulse water turbines.
