本文的目的是比较五种不同的风力发电机系统，即电励磁和永磁励磁直驱发电机系统，永磁和双馈感应发电机系统与单级齿轮箱和双馈感应发电机系统与三级齿轮箱。该比较是基于给定风气候的成本和年发电量。双馈感应发电机与单级齿轮箱似乎是最有吸引力的能量产量除以成本。双馈感应发电机与三级齿轮箱是一个廉价的解决方案，使用标准组件。永磁直驱发电机的发电效率最高，但其价格虽然比电励磁直驱发电机便宜，但比带齿轮箱的发电机系统昂贵
The objective of this paper is to compare five different generator systems for wind turbines, namely the electrically-excited and the permanent-magnet excited direct-drive generator system, the permanent-magnet and the doubly-fed induction generator system with single-stage gearbox and the doubly-fed induction generator system with three-stage gearbox. The comparison is based on cost and annual energy yield for a given wind climate. The doubly-fed induction generator with single-stage gearbox seems the most attractive in terms of energy yield divided by cost. The doubly-fed induction generator with three-stage gearbox is a cheap solution using standard components. The permanent-magnet direct-drive generator has the highest energy yield, but although it is cheaper than the electrically-excited direct-drive generator, it is more expensive than the generator systems with gearbox
