Abstract

This paper proposes an adaptive fuzzy logic based Maximum Power Point Tracking (MPPT) for Permanent Magnet Synchronous Generator (PMSG) based variable speed Wind Energy Conversion System (WECS). The control algorithm, online updates the scaling factors of the Fuzzy Logic Controllers (FLCs) at a high convergence speed. The adaptive FLC is in cooperated along with field-oriented control of PMSG to track the maximum power. The WECS is connected to the grid through a back-to-back converter. The grid side inverter is controlled by voltage-oriented control along with FLC, so that power quality standards of the grid are maintained. The performance of the system is verified using MATLAB Simulink and it is validated that power coefficient of WECS abide at its optimum value with dynamic conditions in wind speed. The WECS provides full reactive power support for the system with a unity power factor operation at the grid. The active power sharing of WECS to the grid/load changes with the availability of wind power.

基于自适应模糊逻辑控制的PMSG风电转换系统最大功率跟踪与电网同步

针对基于永磁同步发电机(PMSG)的变速风能转换系统(WECS)，提出一种基于自适应模糊逻辑的最大功率点跟踪方法。该控制算法在线更新模糊控制器的比例因子，收敛速度快。自适应FLC与PMSG的场向控制相配合，跟踪最大功率。WECS通过背靠背转换器与电网相连。并网侧逆变器采用电压定向控制和FLC控制，以保证电网的电能质量标准。利用MATLAB Simulink对系统的性能进行了验证，验证了在风速的动态条件下，wcs的功率系数保持在最优值。WECS为电网中具有统一功率因数的系统提供全面的无功支持。风电系统对电网/负荷的有功功率分担随风电的可用性而变化。
