| 中文摘要 | 根据双馈风机的暂态特性,详细分析将双馈风机视为恒功率源的可行性,并提出相关限制条件。分析风电机组接入引起潮流分布和系统惯量变化的2种情景,即通过减少同步机出力以平衡新增风电、停运部分同步机组平衡风电;并在此基础上,基于直流潮流模型和等面积定则,分析风电接入后对电力系统暂态稳定性的影响机理。最后,通过仿真分析验证该暂态稳定机理的正确性。; According to transient characteristics of a doubly fed induction generator(DFIG),the feasibility and limitation of regarding a DFIG as a constant power source was analyzed.And this paper analyzed two changes scenarios of power flow and inertia distribution resulted by wind integration in power systems.They are(1)wind power generation lowers down synchronous generation with the system inertia no change;(2)wind power generation makes some synchronous generators offline,therefore changes the power flow and the system inertia at the same time.In view of the above two scenarios,based on DC power flow and equal area rule,this paper studied the mechanism that large-scale wind generation impacted on power system transient stability.Finally,simulation results showed that the transient stability mechanism was with high validity. |
