This paper reports the design, and testing of a water turbine generator system for typical flow rates in domestic applications, with an integrated power management and a Bluetooth low energy (BLE) based RF data transmission interface. It is based on a commercially available low cost hydro generator. The generator is built into a housing with optimized reduced fluidic resistance to enable operat...

The majority of the electricity generated in the United States is produced by steamdriven turbine-generators. A very important step in this power generation process is the condensation of exhaust steam from the final, low-pressure turbine. When the steam condenses, the rapid decrease in vapor-to-liquid specific volumes creates a vacuum at the turbine outlet (monitored as turbine backpressure) t...

The use of hydro-turbine pumps increases the efficiency pumping stations for machine irrigation by utilizing free water energy agricultural sources. savings on achieved through (HTPS) (traditionally obtained electrical networks) creates ecological conditions implementation turbine pumps, while also improving economic stations.

In this paper, linear active disturbance rejection control (LADRC) is employed to deal with the load frequency control (LFC) problem in power systems with a single generator supplying power to a single service area. First, the general (n+1)th order LADRC is given, and then the parameter tuning procedures are presented. It is followed by the description of an LFC problem, in which the case of a ...

Kaplan turbines are nowadays used to provide Frequency Containment Reserve (FCR) the grid due their fast capacity regulate power maintaining high efficiency. However, this continuous regulation increases wear and tear of system considerably. To reduce amount movements in servomotors, thus tear, a new technology is being investigated within frame European project XFLEX Hydro. This based on hybri...

Pico hydro turbines are suitable for low head applications in power plants since their efficiency is more stable than other turbine types. In some situations, computational fluid dynamics (CFD) has also been utilized as well experimental studies the performance prediction of water at a pico scale. Also, CFD methods getting much closer to real conditions terms steady-state with moving references...

Abstract Archimedean screws have been used for centuries, but only pumping water. In the last decades, a growing interest appeared to also use them as hydro turbines electricity generation. While are already well optimized working pumps, studies still carried out identify those parameters that assure best performances when they operate turbines. This paper proposes simple yet efficient procedur...

This paper focuses on expanding and evaluating an automatic generation control (AGC) system of a hydrothermal system by modelling the appropriate generation rate constraints to operate practically in an economic manner. The hydro area is considered with an electric governor and the thermal area is modelled with a reheat turbine. Furthermore, the integral controllers and electri...

Power generation using gas turbine power plants operating on the Brayton cycle suffers from low efficiencies. In this work, a solid oxide fuel cell (SOFC) is proposed for integration into a 10 MW gas turbine power plant, operating at 30% efficiency. The SOFC system utilizes four heat exchangers for heat recovery from both the turbine outlet and the fuel cell outlet to ensure a sufficiently high...
