Analysis of electromechanical power transformers applied in small hydroenergetics

Abstract

At present, in Armenia, hydraulic resources of slow-flowing rivers allow to solve the problem of power supply to small consumers rather efficiently. The electric power generated in small hydropower plants has the lowest prime cost in comparison with that of the power generated by other renewable and traditional power sources. At their construction, in contrast to powerful hydropower plants, the ecological damage (land flooding, destruction of fish farming, the change in the balance of the local climatic condition, etc) are practically excluded. In the present work, issues on applying different types of electric generators in small hydroenergetics are considered. The main advantages, disadvantages and also recommendations on applying electrical generators at their utilization in small hydropower plants are introduced. The developed external damper system for the synchronous hydro aggregate is introduced.

Mažojoje hidroenergetikoje naudojamų elektromechaninių jėgos transformatorių analizė


Santrauka


Šiuo metu Armėnijoje nesraunių upių hidrauliniai ištekliai sudaro galimybes gana veiksmingai spręsti elektros energijos tiekimo mažiesiems vartotojams problemą. Mažų hidrojėgainių sukurtos elektros energijos savikaina yra pati žemiausia, lyginant su kitų atsinaujinančių ir tradicinių energijos šaltinių sukuriamos energijos savikaina. Statant mažąsias jėgaines, skirtingai nei galingas elektrines, ekologinės žalos (žemių užliejimas, žuvininkystės ūkio griovimas, vietinių klimato sąlygų pusiausvyros pokyčiai ir t. t.) praktiškai nebūna. Šiame darbe svarstomi skirtingo pobūdžio elektros generatorių naudojimo mažojoje hidroenergetikoje klausimai. Pristatomi svarbiausi pranašumai, trūkumai, taip pat rekomendacijos, kaip naudoti elektros generatorius mažose elektros jėgainėse. Pristatoma sukurta sinchroninio hidroagregato išorinė slopinimo sistema.
