| 摘 要： | 传统的变速双馈风电机组解耦控制策略对于系统频率支撑作用微乎其微。文中在分析变速双馈风电机组参与系统频率控制特性的基础上，在传统变速双馈风电机组解耦控制中附加风电机组频率控制单元。控制系统包含频率控制、转速延时恢复、转速保护系统和与常规机组配合等4个功能模块。仿真结果表明，该控制策略不仅对暂态频率偏差具有快速的响应能力，而且能够使转子转速以更快的速度恢复到最佳运行状态，证明了基于变速双馈机组的风电场能够在一定程度上参与系统的频率控制。

| Abstract: | The conventional decoupling control in the variable-speed doubly-fed wind turbines has little support to the system frequency.The characteristics of doubly-fed induction generator wind turbines in the system frequency control are analyzed.A revised frequency control based on the conventional decoupling control is proposed.The control system consists of four functional modules,i.e.frequency control,rotational speed delaying recovery,speed protection and coordination control with conventional generators.Simul... |
