摘要

为了改善风电接入系统的同步稳定性，采用基于能量守恒的方法构造含有风电机组的电力系统能量存储函数，以此为基础设计提高风电接入系统动态特性的双馈风力发电机控制策略，并分析了机组运行约束对控制效果的影响。控制方案利用变速风电机组特性，通过改变风机转速消除系统故障期间的不平衡能量，有效抑制系统同步机振荡。针对双馈感应型风场接入系统，在DIgSILENT/Power Factory中进行了仿真研究，仿真结果表明，不同系统运行方式下控制方案在有效改善风电接入系统同步稳定性的同时不会恶化系统电压稳定特性。

Abstract

To improve the synchronous stability of the power system integrated with wind generators， a wind power system energy function is proposed based on the energy conservation law. Then a stability control strategy based on the energy function is introduced. The impacts of double fed induction generator（DFIG） operation limits on the control are also discussed. In the variable speed operation mode， the wind generators eliminate the unbalancing energy to restrain the system oscillations. A testing system including a DFIG-based wind farm is realized using DIgSILENT/Power Factory to demonstrate the effectiveness of this strategy. The simulation results show that， in different system operation modes， the control strategy is effective in improving the power system synchronous stability without deteriorating the system voltage stability.
