为了保持功率储备，以有助于变速风力发电机的一次频率控制，本文分析了两种控制策略：转矩控制策略和基于模糊逻辑的多变量控制策略。第一种也是最简单的策略允许仅当风力涡轮机发电机在满负荷下工作并且需要先验地或由网络管理器确定功率参考值时才维持常规储备。第二种控制策略允许在没有任何风速测量的情况下克服这些限制;它在真实的时间内确定发电机功率参考值以维持固定的最小储备。本文的主要结果表明，在较大的风速范围内保持有规律的备用是可能的。当考虑风力发电场时，由于风速分散，该储备更有规律。所提出的一次频率控制策略的性能与模拟的帮助下，考虑一个风电场，包括三个风力发电机。
To maintain a power reserve to contribute to the primary frequency control with variable speed wind generators, two control strategies are analysed in this paper: a torque control strategy and a fuzzy logic based multivariable control strategy. The first and most simple strategy allows to maintain a regular reserve only when the wind turbine generator works at full load and needs the determination of a power reference value a priori or by the network manager. The second control strategy allows to overcome these limits without any wind speed measurement; it determines in real time the generator power reference value to maintain a fixed minimum reserve. The main result of this paper is to shown that it is possible to maintain a regular reserve on a large range of the wind speed. This reserve is still more regular when considering a wind farm owing to the wind speed dispersion. The performance of the proposed primary frequency control strategies is shown with the help of simulations by considering a wind farm including three wind generators.
