“…The measured discharge (Q) of water and the amount of electrical power generated by with a head of 10 cm are shown in Table 2. The theoretical power (Pin) is proportional to the height (h) and discharge (Q) (Safdar et al, 2020). This is in accordance with the equation that was discussed in the previous chapter, specifically .…”

Nowadays, direct media use in learning energy is rarely found. Therefore, the authors intended to design a mini micro-hydro power plant (MHPP) in order to give direct experiences to students. This study generally aims to develop a mini MHPP consisting of equipment design, component selection, and the MHPP assembly. A test on discharge, heights, and produced power is then conducted. The data acquired are then analyzed in terms of either Pteotirik or Preal power using a predetermined equation. An analysis to the factors influencing the P values is then carried out. The power input of resulted from the water discharge management is 35.64 mW, while that of the power output is 9,61 mW. The efficiency of the MHPP set is by 26.96% which is considered quite low due to such factors as turbine blades, penstock pipes, generators, and the shift from water potential energy to other types of energies which is inevitable. It is expected that the developed mini MHPP is applicable as practicum learning media giving a lot of such learning experiences to students as to identify how hydroelectric power plant is, how the water energy shifts into electric energy, how high the electricity produced is, and to analyze factors influencing how high and low the electricity produced by a power plant.

“…This means that with a large discharge Q, a high dam with a small discharge Q will generate the same power as a low dam. In addition, the efficiency of all generating components is also affected by the amount of electrical energy generated (Safdar et al, 2020).…”

“…There is also the consideration that once the turbine is installed, updating the design scheme could be quite costly [12]. As such, alternative economic and cost-effective options are required to be reduced the price while also promoting Pico-hydropower production as a widely known power source for rural residents [13][14][15].…”

The primary goal of this paper is to evaluate an innovative Z-Blade turbine technology and its potential implications for production costs and manufacturing techniques. From literatures, conventional pico-hydro technologies with a capability of less than 5kW are getting more and more attention as good alternatives to environmentally friendly power generation, but there are more expensive and complex for small power generation and small domestic consumer level. Therefore, a Z-Blade reaction turbine technical and environmental processes as well as financial research are described in-depth. The methods for a Z-blade turbine design and implementation are described here, and also the material using for the Z-Blade turbine is a grey PVC pipe. Moreover, empirical description, designation, costing, and correlation are employed in the process of critically analysing the simple reaction water turbine novels. Also in this article, the manufacture of the Split Reaction Turbine (SRT) and Cross Pipe Turbine (CPT) was re-evaluated to take into consideration the technological and economic factors as well as the difficulties of both turbines. In the meantime, low-head, low-flow water resources used to examine additional features of Z-Blade. Theoretically, such a platform for hydro production is cost - effective and has a simplistic design methodology with a total cost of USD76 that equates to 7.6% of the overall installation cost and worthy of output up to 115W of mechanical energy.

“…A Pico hydro is defined with different capacities, namely <10 kW [2] and <5 kW [3], while a verylow head is a less than 3 m head [1]. Studies related to VLHPHP with a power of <5 kW are being focused on the main components, namely the very-low head Pico hydro turbine [4]− [7], generator [8], [9], power controller [10]− [12], as well as a combination of two or all of these components [13]− [16].…”

<span>This paper analyzes the performance of a pico hydropower plant consisting of an axial hydro turbine integrated with a permanent magnet generator (PMG) and connected to a power converter. The proposed system is aimed to obtain a wide system operation range to gain more power captured while maintaining time-harmonic distortion in voltage (THDv) that meets the standard. The PMG specification is 1 kW, 1 phase, 235 V, 50 Hz, 83 rpm. The design and simulation of PMG were carried out by analytical and numerical calculations using FEMM 4.2. The power converter was simulated using PSIM and functions to reduce the THDv and pass the generator voltage between 50–500 V. The results show the THDv of the generating system at the upper and lower limits of the passed voltage having a THDv below 5%. Meanwhile, the PMG performance characteristics at various currents and rotations produce efficiency of 87.20% at nominal current. From these results, it can be concluded that the pico hydropower plant works well as desired.</span>
