Abstract

Permanent Magnet Generator has been widely used in Variable-Speed Wind Energy Conversion System (VSWECS). Fuzzy Logic Control (FLC) of the generator side converter has the ability to have good regulation of the DC-link voltage to meet the requirements necessary to achieve optimal system operation, regardless of the disturbances caused by the characteristics of the drive train or some changes into the DC-load. The main focus of this paper is to present a model for a three-phase voltage source space vector pulse width modulation (SVPWM) rectifier which is connected to a PMSG in a wind turbine system, where a direct voltage control (DVC) using FLC based on voltage orientation strategy is used to control the mentioned rectifier. The control algorithm employs a fuzzy logic controller to effectively achieve a smooth control of DC-link voltage under wind/load perturbation conditions. Some simulation results, using Matlab/Simulink, are presented to show the effectiveness of the SVPWM rectifier Connected to a PMSG WECS with the proposed control strategy.

风/负载扰动条件下PMSG wcs连接PWM整流器基于模糊逻辑的鲁棒DVC设计

永磁发电机在变速风能转换系统中得到了广泛的应用。发电机侧变流器的模糊逻辑控制(FLC)能够对直流链路电压进行良好的调节，以满足实现系统最佳运行所必需的要求，而不受传动系特性的干扰或直流负载的某些变化的影响。本文的主要重点是提出了一个三相电压源空间矢量脉宽调制(SVPWM)整流器的模型，该整流器连接到风力发电系统的PMSG，其中使用基于电压定向策略的FLC直接电压控制(DVC)来控制所述整流器。控制算法采用模糊逻辑控制器，有效地实现了风负载摄动条件下直流链路电压的平滑控制。利用Matlab/Simulink进行了仿真，验证了该控制策略对连接到PMSG WECS的SVPWM整流器的有效性。
