“…The voltage source converter (VSC) serves as the dc-ac interfacing medium providing tight regulation of frequency and the magnitude of the terminal ac voltage. In summary, the proposed scheme replaces the ELC/dump-load unit adopted in [1]- [4] by an electronically controlled FC/UC/ELZ unit, thereby providing self-sustainable power solution for wide range of operating conditions. While sizing the units, it is roughly estimated that the generation and the demand of energy would match in long term by using H 2 medium, with no need of importing it.…”

“…Further, due to the small size of generator (<100 kW), the governor action is not incorporated making the free flow of water to hit the turbine. In such case, the MHP designers have been adopting the electronic load controller (ELC) and dump load to balance the power against the varying load [1]- [4]. An ELC is a power electronics system, either IGBT/thyristor switches feeding ac load [4] or the rectifierchopper feeding dc load [1]- [3], allowing designated current flow through the dump load.…”

For the flexible operation, the latter, similar to the static synchronous compensator (STATCOM), is preferred as it provides many supplementary functions like variable var supply, harmonic and unbalance compensations, etc.…”

Abstract-This paper explores the control and operational aspects of introducing fuel cell/electrolyzer/ultracapacitor (FC/ELZ/UC) unit into a microhydro power system, replacing the conventional electronic load controller/dump-load unit. FC/ELZ is expected to provide long-term energy balance by utilizing the hydrogen technology, whereas the UC is employed as buffer storage for the transient compensation. System configuration is proposed, control scheme is designed, and the detailed dynamic modeling is developed for each component of the system. Expected behaviors during the sudden load change and hydro input variation are observed by mathematical simulation. Finally, the results of the analysis are summarized with their applicability to real system and the limitation/further scope are indicated.

“…The generated power is more than the consumed power then the generator speed increases which causes to increase in generator terminal voltage and frequency. For keeping up the terminal voltage and frequency of the generator constant, the electronic load controller [5]- [7] is proposed. ELC operation depends on total generated and consumed power should be matched.…”

“…The machine saturation is used as a voltage control component. If generation is performed using constant power, as in the case of hydropower turbines, electronically-controlled loads are used as a voltage-stabilizing element [12,13]. These generators are based on a fourth-degree model, whereas a switching reluctance machine (SRM) has a second-degree model for each phase [14,15].…”

Energy Transformations in a Self-Excited Switched Reluctance Generator

Abstract:Wind generation systems require mechanisms that allow optimal adaptation of the generator to varying wind speed and to extract maximum energy from the wind. Robust and affordable high-performance methods are also needed for isolated sites. This paper takes this approach, in which an AC switched reluctance generator is used as a generator with a variable rotor speed. Although the voltage obtained is of insufficient quality to connect the generator directly to the power grid, this kind of generator can be used in isolated sites to charge a battery bank with a simple bridge rectifier. Due to the nonlinear behavior of the machine with the position and current, along with the alternating nature of the current that circulates through its phases, the machine experiences cyclical energy transformations of a mechanical, electrical and magnetic nature. This paper analyzes these transformations for the purpose of providing guidelines for machine design and optimization as a wind turbine in isolated sites.
