Efficient simulation of wind farms using switching reduced models of converters and VBR formulation of six-phase PM synchronous generators

Wind generation systems with variable frequency generators commonly utilize several power electronics converters. Using numerically efficient models for converters and electrical machines can decrease simulation time of wind farms. In this paper, a voltage-behind-reactance model is developed for a six-phase permanent magnet synchronous generator. Then, a multiresolution simulation methodology is presented which utilizes different combinations of detailed and average-value models of twelve-pulse rectifier and three-phase inverter systems in conjunction with different six-phase machine models. The presented models are verified through simulations to provide superior performance in terms of speed and numerical efficiency.
