1. Introduction. A brushless doubly-fed generator (BDFG) may be an attractive solution to reliability and maintenance issues of carbon brushes and slip-rings with a conventional doubly-excited induction generator (DFIG) while offering competitive performance and the same economic benefits of partial power electronics [1].For a
The project "Brushless wind power generator for limited speed range" has been carried out within the research program Vindforsk IV. Vindforsk IV coordinates eighteen projects, which provide knowledge and innovations to the wind industry. Energimyndigheten, together with companies in the wind industry through Energiforsk AB, funds the program.
A simple permanent magnet DC motor, like the ones that used to be common in battery-operated toys and model kits, work as generators without trouble. But a DC brushless motor has MOSFETs controlled by a microcircuit to switch power to the stator coils. The microcircuit can only be powered from the outside. –.

In a typical wind energy conversion system, the turbine output torque on the generator side of the gear-box for the maximum energy extraction from the wind i.e. the maximum power point tracking (MPPT) in the base speed region (i.e. between the minimum ''cut-in'', u min, and the rated wind speed, u r), can be represented as [2], [18]: (19) T
As a result, the BDFRG gained more preference than that of the doubly fed induction generator. Moreover, this result led to the emerging of the (BDFRG) as one of the most promising generators in the new modern wind turbines.

Abstract: The brushless doubly-fed wind power system based on conventional power control strategies lacks ''inertia'' and the ability to support grid, which leads to the decline of grid stability. Therefore, a control strategy of brushless doubly-fed reluctance generator (BDFRG) based on virtual synchronous generator (VSG) control is proposed to solve
