A review on non-conventional hydropower turbines and their selection for ultra-low-head …
When classifying the hydropower based on working pressure head, ultra-low-head falls in the range of 0 m–3 m and is also referred to as extra-low-head [3] or micro head [4], or very-low-head [5]. Most of the published works emphasize the small category of hydropower technologies (static heads between 2m and 30 m ) [ 6 ] or kinetic energy …
Operation, performance and economic analysis of low head micro-hydropower turbines …
Head is a criterion for classification of hydropower turbines, which are either classified as high-head, medium-head, or low-head, as shown in Table 2. The turbine selected for micro-head hydropower systems should be <10 m.
Performance of a low-head pico-hydro Turgo turbine
In this paper, the operation of a single-jet Turgo turbine outside of this typical application domain is investigated, at low heads of 3.5 m down to 1 m, a typical head range available for remote communities. A 2D quasi-steady-state mathematical model with low computational requirements is developed, to arrive at a base-line design.

Low Head Turbines - Fit for the future. When Austrian professor Viktor Kaplan (1876–1934) filed his essential patents for the eponymous turbine in 1912 and 1913, he opened the way for a new technology able to use low hydrostatic heads for power generation in an economically feasible way. Now, considering low-head applications …
Planning a Microhydropower System | Department of Energy
Planning a Microhydropower System. To see if a micro-hydropower system would work for you, determine the vertical distance (head) available and flow (quantity) of the water. To build a micro-hydropower system, you need access to flowing water on your property. A sufficient quantity of falling water must be available, which usually, but not ...

Low-head pumped hydro storage: A review of applicable …
In this work, the European Small Hydropower Association (ESHA) classification defines low-head, and states that low-head hydropower plants have a head of 2-30 metre [37]. The overall efficiency of a low-head power plant is more sensitive to head losses than a high-head alternative, and low-head PHS requires that the pipelines …

In recent years, a very-low-head turbine has been demonstrated to be suitable for operating under ULH conditions as an innovative axial-flow hydraulic turbine [67], [68]. Conventional cross-flow turbines ( Fig. 5 ) pushed by water jets usually are used for a wide range of hydraulic heads ranging from 5 to 200 m [69] .
Nevertheless, the utilization of ultra-low-head (ULH) water energy (i.e., situations where the hydraulic head is less than 3 m or the water flow is more than 0.5 m/s with zero head) has...
Specifically, the low environmental impact of ULH hydropower is reflected in two main points: 1) the wide blade passages and low rotating speed can significantly …
