“…The two axis frequency response characteristics will be found using the same decomposition technique proposed in [6] over the data obtained by testing the machine with its rotor at standstill in an arbitrary position. Recent works have shown the need of further studies on this subject [7]- [9].…”

In this article, a Standstill Frequency Response Test (SSFR) is proposed, with the aim of determining the direct and quadrature axis operational impedances for salient pole synchronous machines. The method is applied with the rotor at standstill in a given arbitrary position, thus avoiding the difficulties in rotor mechanical alignment and rendering it suitable for large salient pole synchronous machines of hydroelectric power plants.

“…Entre os principais ensaios, o SSFR é um procedimento normatizado pela IEEE [4], utilizado principalmente no levantamento de parâmetros de grandes unidades geradoras. Esse ensaio apresenta vantagens sobre outros métodos de caracterização dinâmica, uma vez que não submete a máquina a altos estresses eletromecânicos como o teste de curto-circuito abrupto e não necessita instrumentação especial, podendo ser realizado com baixo custo [3].…”

“…As medidas são tomadas em duas diferentes condições: com o rotor alinhado ao eixo magnético do estator e em quadratura a este eixo. O alinhamento correto do rotor e desconsideração dos efeitos da saturação são alguns dos problemas do procedimento [4], [5].…”

O objetivo deste artigo é apresentar a modelagem e a identificação de parâmetros dinâmicos de máquinas síncronas de pequena potência, tal como aquelas empregadas em nano e pico-aproveitamentos hidrelétricos. Inicialmente, no domínio do tempo, o comportamento dinâmico do Gerador Síncrono (GS) é analisado de forma a obter um modelo baseado em coordenadas dq0. Uma vez definido o circuito equivalente da máquina, é realizada uma análise no domínio da frequência para se obter o modelo de pequenos sinais que serve de base para o teste de resposta em frequência com rotor em repouso (SSFR, do inglês Standstill Frequency Response). Assim, é relatada uma aplicação do teste em um GS de 5 kVA, propondo uma abordagem onde são medidas apenas duas funções de transferência do modelo de pequenos sinais e fazendo uso dos testes clássicos de máquinas síncronas para melhorar os resultados. Os parâmetros obtidos são simulados e comparados com a máquina real.

This paper compares the different versions of hardware realization of low-cost device for standstill frequency response SSFR testing. The SSFR testing is a modern method used for testing and parameter identification for electrical machines especially for synchronous machines (high power generators for power stations). This paper shows the methods how to realize this SSFR testing device for machine identification by general purpose components (to achieve universal device not only for SSFR testing but also for purposes of more universal usage (i.e. measuring of non-linear power systems, power system fault identification, nonsymmetrical differences measurement, etc.). This modern method makes it possible to replace the Sudden Shortcircuit Measurement Method and thus saves the mechanical construction and lifetime of the machine, which might be otherwise reduced due to the strong dynamic forces that occur in this type of measurement. Proposed devices were realized in university laboratories for purpose of getting acquainted with the practical properties of this method and also for didactic purposes (both in terms of the SSFR method itself and in term of realization of a real equipment with given properties).
