摘要
针对能宽转速运行的定子双绕组感应发电机(DWIG),建立一套能并网运行的风力发电实验系统。通过该系统,研究DWIG在宽风速范围内并网运行的控制规律以及适用于DWIG风力发电系统的并网逆变器控制策略,为实现系统的最大功率追踪提供实验依据。另外,根据DWIG及其并网逆变器在控制策略上的特殊性,研究适用于该系统的最大功率追踪策略。实验证明了DWIG风力发电系统并网运行的可行性以及控制策略的有效性。
A grid-connected wind power generation system was designed, based on a novel dual stator-winding induction generator （DWIG）. The control rules of the grid-connected DWIG wind power system operating in a wide wind speed range and the control strategy of the matched grid-connected inverter were both tested with the proposed system, which offers an experimental support for maximum power point tracking （MPPT）. In consideration of the specific characteristic of DWIG and corresponding grid-connected inverter, a suitable particular MPPT scheme was presented. Experimental results demonstrate the feasibility of the proposed system and the accuracy of MPPT scheme.
