摘要：

摘要：作为一种新的发电方式，双馈风力发电机的大量接入给电力系统的动态行为带来影响。随着风电装机容量的不断增大，其对电力系统安全、稳定特性的影响将逐渐显现。从减少同步发电机出力和等容量替换同步发电机２个角度，分别对双馈风力发电机组接入电网后同步发电机的功角稳定性进行理论分析和仿真验证。研究结果表明双馈风电机组接入系统后在一定程度上有利于电力系统功角稳定特性。

Abstract:

Abstract:As a new generation mode,a large amount of the integrated doubly fed induction generators (DFIG) have an effect on the dynamic behaviors of the power system.With the installed capacity of DFIG based wind power increased,this impact on the power system stability is gradually emerging.In this paper,the theoretical analysis and simulation verification for the angle stability of the synchronous generator after the DFIG connected to the grid are studied from two aspects,one is reducing the synchronous generator output and the other is replacing the generators with the equally capacity DFIG.The results demonstrate that the DFIG connected to the system is benefit for the angle stability of synchronous generators to a certain extent.
