“…7 where the frequency of the secondary currents and voltages have been translated to the primary currents. This result is almost identical to the equivalent circuit for the DFIG developed in [7]. The similarities in the models for the BDFRM and DFIG give the BDFRM the same benefits as the DFIG:…”

“…This type of machine has been in use since the early application of the induction machine, however, it is only since the advent of lower cost power electronics that it has been widely used as a DFIG. The DFIG model has been widely studied elsewhere ( [7]) and is only presented here to place the BDFRM in context. The steady state equivalent circuit for the DFIG is shown in Fig.…”

This paper discusses the developing electrical needs for wind tower generators (WTGs), and highlights the merits of brushless doubly fed reluctance machine (BDFRM) for these applications. There is a brief development of models for the doubly fed induction generator (DFIG) and BDFRM generator. These models show their similarities and how the BDFRM can be used instead of the DFIG, with the added benefits of brushless operation.

“…In [8], it was claimed that the rotor iron is a function of s and changes sign when s changes sign. It proposed to have the iron loss represented by a resistance in series with the rotor winding resistance.…”

“…8 has some advantages over the ideas presented in [8]. First, if rotor iron loss is represented by a resistor in series with rotor winding resistance as suggested in [8], then rotor iron loss would have been proportional to rotor current. As rotor iron loss is only proportional to the magnitude and the frequency of rotor flux densities, it should not be related to rotor currents.…”

This paper presents the modeling, control, and implementation of a novel variable-speed constant-frequency power generation system for renewable and distributed energy applications. The generation system consists of a wound-rotor generator, a brushless exciter and a low-rating controlled power converter. The main generator is a doubly fed induction machine which is operated as a synchronous generator. The advantages of the proposed system are reduced harmonic injection to power grid, wide speed operation range covering both subsynchronous and super-synchronous speeds, self var support, and increased reliability. It can be directly applied to wind power generators, small-scale hydroelectric generators, stand-alone diesel and gasoline generators, and aerospace and naval power generation systems where a variable speed turbine/engine is employed. An equivalent circuit model of a doubly fed generator was developed incorporating stator and rotor iron losses. Then the control of a standalone generation system is developed based on the mathematical model. Detailed implementation procedure is given. An experimental system and its control were implemented using an embedded real-time digital signal processor. Measurements of the experimental system validated the system design and readiness for prototyping in a relatively large power range.
