A review on electromechanical equipment applicable to small hydropower plants

Abstract

SUMMARY Small hydropower (SHP) projects are considered by the developers as these provide renewable source of energy and are environment friendly. The basic cost components of SHP scheme are broadly classified as civil works and electromechanical equipment. The most important components under the electromechanical equipment are turbine and generator. In the present paper, an attempt has been made to review the different types of technological models and transfer function developed to evaluate the performance of the electromechanical equipment of SHP projects. A review on the different types of control strategies developed by earlier investigators has also been presented. The present review attempts to cover the different types of design and analysis made on different types of turbines, generator and control equipment of SHP. Copyright © 2012 John Wiley & Sons, Ltd.

A qualitative multi-attribute model for the selection of the private hydropower plant investments in Turkey: By foundation of the search results clustering engine (Carrot2), hydropower plant clustering, DEXi and DEXiTree

“…On the other hand, the general consensus of the classification of the installed power of the hydropower plants was almost achieved according to the name/title of the installed power of the plants as large, medium, small, mini, micro and pico -159-Journal of Industrial Engineering and Management -http://dx.doi.org/10.3926/jiem.1142 hydropower plants. Some academics worked on the classification of hydropower plants by the installed power or capacity (P) (see Anderson, Doig, Khennas & Rees, 1999;Castaldi, Chastain, Windram & Ziatyk, 2003;Mishra, Singal & Khatod, 2012;Paish, 2002;Voros, Kiranoudis & Maroulis, 1999). The simple clustering algorithm in this model was built up according to the Algorithm 1 on Figure 1 (0 to 1, 1 to 10, 10 to 100, and 100 to 1.000 in MW).…”

Analysis of Electromechanical Power Transformers Applied in Small Hydroenergetics / Mažojoje Hidroenergetikoje Naudojamų Elektromechaninių Jėgos Transformatorių Analizė

“…The low sensitivity to the short circuits is conditioned by the deexcitation of the induction generator at a short circuit. The high degree of protection is easily ensured due to the simplicity of the structure (Ramos et al, 2000;Vol'dek, 1978;Pyrhonen et al, 2008;Mishra et al, 2012;Tes, 2017b). The disadvantage of an induction generator is the consumption of reactive power consumed from the network when the generator operates paralelly with the network.…”

A selected literature review of efficiency improvements in hydraulic turbines

“…Hydropower plants often get lots benefit from air admission or air injection [30][31][32], because which smoothes out the annoying high-frequency components of noise and vibration. In addition, aeration sometimes removes flow instability by manipulating the hydraulic transmission behavior -in particular lowering the draft tube natural frequency [33].…”
