摘要/Abstract

摘要：

基于状态空间建模的方法建立了不同风电场经交直流并联接入电网系统的小扰动模型,并对系统中所产生的各种振荡模式的产生机理进行了详细分析;进一步分析了系统结构参数与关键控制器参数对系统次/超同步振荡固有振荡模式与耦合振荡模式影响的差异性;在此基础上,揭示了交流系统与直流系统之间交互作用的机理与影响因素。最后利用PSCAD/EMTDC平台进行时域仿真证实了所建立系统的正确性,结果表明,系统参数对交直流系统之间的耦合振荡模式影响较为复杂。

Abstract:

Applying the state space modeling method, the small disturbance models of different wind farms connected to the power grid through paralleled AC and DC lines are established, and the generation mechanism of various oscillation modes in the system is analyzed in detail. Furthermore, the differences of the effects of system structure parameters and key controller parameters on the natural oscillation mode and coupled oscillation mode of the system are analyzed. On this basis, the interaction mechanism and factors between AC and DC system are revealed. The correctness of the system is verified by time-domain simulation on PSCAD / EMTDC platform. The results show that the influence of system parameters on the coupled oscillation modes between AC and DC systems is complex.

Key words: eigenvalue analysis method, AC/DC hybrid connection, sub-synchronous and super-synchronous oscillation, interactive influence
