摘要
针对风速不稳定性给风电并网时电能质量带来的严重影响,介绍了一种能够监测并改善风电机组电能质量的系统设计方案。系统采用双馈风电机组,以TMS320F28335为控制核心,通过对电机定子、转子侧电压、电流、频率等信号的采集和分析,结合风速预测和功率控制技术,实时有效地调整输出功率,从而达到改善风电质量的目的。该设计方案对提高监测系统的准确性,降低风电并网对电网的不利影响,提供了理论依据,具有一定的参考价值。
Aiming at wind speed instability which brings the serious effects on power quality, this paper presents a de- sign to monitor and improve power quality of wind turbine. Through collecting and analyzing voltage, current, frequen- cy of motor stator and rotor it adopts doubly-fed induction generator （DFIG） and takes TMS320F28335 as control core to improve power quality combining with wind speed prediction and power control. This solution provides a theoretical basis which is useful to make monitoring system more accurate and reduce the impact of wind power integration.
