This paper shows an improvisation for gas turbine power plants. It incorporates a hydraulic compressor to compress air prior to combustion. The aim is to reduce in-house consumption of the power generated in the turbine, thus increasing the overall efficiency of the power plant. The proposed compressor could also be used in different scenarios.

Nowadays, hydropower plays an essential role in the energy market. Due to their fast response and regulation capacity, hydraulic turbines operate at off-design conditions with a high number of starts and stops. In this situation, dynamic loads and stresses over the structure are high, registering some failures over time, especially in the runner. Therefore, it is important to know the dynamic r...

Nowadays, the pump-storage power plants are a proven solution for storing electricity at large scale and offering flexibility to the power management. Therefore, the hydraulic machines are increasingly subject to off-design operation, start-up and shutdown sequences. However, the fast and frequent switching between pumping mode and generating mode presents technical challenges. In the present s...

Field performance testing of hydraulic turbines is undertaken to define the head-power-discharge relationship, which identify the turbine’s peak operating point. This relationship is essential for the efficient operation of a hydraulic turbine. Unfortunately, in some cases it is not feasible to field test turbines due to time, budgetary, or other constraints. Gordon (2001) proposed a method of ...

This paper is focused on the guide vane cascade as one of most crucial stationary sub-systems hydraulic turbine, which needs to provide efficient inflow conditions runner. The vanes direct flow from spiral casing and stay towards runner, regulating desired discharge. A parametric design tool with normalized geometrical constraints was created in MATLAB, suitable for generating geometries Franci...
