A novel concept for micro hydropower plants based on synchronous reluctance generators

This paper provides an overview of the unused potential for micro hydropower plants in Croatia and presents a novel power generation system concept for micro hydropower plants. The proposed concept is based on a variable speed turbine and synchronous reluctance generator coupled with the full-scale power converter thus forming a flexible system capable of active and reactive power control. The variable speed operation ensures minimal system loss for various flow rates, provides high dynamics of power control and exploits the turbine in a wide operating range, while the power converter increases the efficiency and the functionality of the system. The synchronous reluctance generator is proposed due to its robust design, high efficiency, high reliability, and low cost. The proposed concept will be further developed, implemented, and experimentally verified at the University of Zagreb under research project HYDREL, and the multiple challenges that must be addressed are discussed in this paper.
