“…In small and run-of- can be used to maintain an acceptable efficiency amid the wide range of head and discharge rates. But an alternative solution is to use simpler and cheaper propeller turbines equipped with variable-speed technology [10], [34]- [36]. This technology could help in developing small hydropower projects where environmental impacts are less significant compared to large plants.…”

In ThIs arTIcle, The sTaTe of The arT In the variable-speed operation of hydropower plants is reviewed, with a focus on pumped-storage hydropower. relevant literature is reviewed to address the benefits of variable-speed operation for both power systems and hydropower facilities. Two main configurations to enable variable-speed operation-the doubly fed induction machine (DfIM) and the converter-fed synchronous machine (cfsM)are discussed and compared. The article addresses the technology and energy policies of the past, present, and future and points out how the motivation, services, value, and technology of variable-speed hydropower plants have been subject to considerable change.

Abstract:In many developing countries, there are regions where the electrical grid is weak or nonexistent. However, in these areas, large amounts of distributed energy sources, such as hydro, are often available and could be suitably exploited. To this aim, the low head hydro power plants can play a significant role. In fact, recent technological advances in mini-hydro turbines and decreasing costs of static electricity conversion devices enable to realize suitable power plants for an efficient and profitable exploitation of these sites. One of the major challenges is the integration of the above-mentioned power plants into autonomous electrical systems, islanded and/or disconnectable from the main distribution network. In this paper, an innovative control strategy for a low head hydro power plant supplying users in small clusters of villages is proposed.

The paper intends to re-design a permanent magnets synchronous generator (PMSG) having low efficiency, in order to bring it in the range of actual generators. The starting point was a real machine which was transformed from induction machine into permanent magnets machine for series production. It had low efficiency and low power factor. By following the operational aspects of the machine and the theoretical phenomenon presented by electrical machines manufacturers, the machine was re-designed and a superior efficiency was obtained.
