| 摘 要： | 首先,建立互联系统接入变速风电机组后的动态模型,推导虚拟同步电力系统的暂态能量函数,分析表明在不同振荡阶段,惯性控制对暂态能量转换过程的影响不同;其次,提出两区域协同变惯性控制策略,改善含虚拟惯性互联系统的功角稳定性。最后,搭建风电高渗透的四机两区仿真系统,验证所提控制策略能够兼顾频率调节功能,并改善系统的动态稳定性。

| Abstract: | Firstly,both the dynamic model and the transient energy function of a two-area interconnected system connected with the variable speed wind turbines are established.Analysis presents that inertia has distinctive effect on transient energy conversion during different oscillation stages.Secondly,this paper proposes a variable-inertia control strategy based on the cooperation of two power generation area,which can improve the transient multi-swing stability of power angle in interconnected system.Finally,an interconnected system containing four synchronous generators and two wind farms is built to verify the validity and implementability of the proposed control strategy.The results show that both regarding the frequency control ability and the transient multi-swing stability are all underpinned. |
