摘要介绍了一种基于新型混合励磁同步发电机的直驱式风力发电系统。根据风力机特性和混合励磁同步发电机的特点,提出一种不依赖风机参数和空气密度的变步长最大风能跟踪控制算法,通过实验得出一种变步长经验算法,使系统更快速有效地实现最大风能跟踪。搭建了基于混合励磁同步发电机的风力发电系统试验平台。实验结果表明：该算法不仅能在风速变化时自动搜索到每一风速对应的最佳转速,实现风机最大风能的捕获,而且具有对快变风速的动态响应能力,验证了控制方案的正确性和可行性。

Abstract：A novel direct-driven type wind energy conversion system based on hybrid excitation synchronous generator(HESG) is introduced in this paper. A variable-step maximum power point tracking(MPPT) algorithm for direct-driven wind energy conversion system based on HESG is proposed,which is independent of the turbine parameters and air density. The algorithm searches for the Peak Power Points by varying the speed in the desired direction. An experimental setup had been built to validate the feasibility and effectiveness of proposed control strategy. The experimental results show that the proposed variable-step search algorithm not only can search for the optimum speed automatically and realizes MPPT but also is run for the different wind velocities.

Key words： Hybrid excitation synchronous generator wind power generation variable step maximum power point tracking

基金资助:本课题研究采用台达环境与教育基金会《电力电子科教发展计划》（DRES2007002）资助研发的新型混合励磁同步发电机,其结构如图2所示^[14]。装在定子上的直流励磁线圈首先在旋转的转子上感应出交流励磁电流,又经转子上的整流器给位于转子上的励磁绕组励磁,和永磁体共同产生气隙磁场,在定子上感应出电动势。由于发电机的气隙磁场由永磁体和电励磁共同产生,通过调节电励磁绕组中直流电流来调节气隙磁场的大小,实现磁场平滑可调。
