Abstract

By increasing in the penetration level of wind turbines, the influence of these new added generation units on the power system oscillations specifically inter-area oscillations has to be thoroughly investigated. In this paper, the impact of increasing in the penetration of full rate converter wind turbines (FRC-WTs) on the inter-area oscillations of power system is examined. In order to have a comprehensive evaluation of the effects of FRC-WT on the inter-area oscillations, different scenarios associated with the wind power penetration levels, wind farm locations, strength of interconnection line, and different operating conditions of synchronous generators are investigated. The synchronous generators, exciter systems and power system stabilizers (PSSs) as well as the FRC-WT grid-side converter and its related controllers are modelled in detail in Matlab in order to evaluate the effects of FRC-WTs on the inter-area mode oscillations precisely. The results show that FRC-WTs can affect the inter-area oscillations considerably in some simulation scenarios.

全变流器风力发电机组对电力系统区域间振荡的影响

通过增加风力发电机组的渗透水平，必须深入研究这些新增发电机组对电力系统振荡特别是区域间振荡的影响。本文研究了全速率变流器风电机组侵彻量增加对电力系统区域间振荡的影响。为了全面评价FRC-WT对区域间振荡的影响，研究了与风电渗透水平、风电场位置、互联线路强度和同步发电机不同运行条件相关的不同情景。在Matlab中对同步发电机、励磁系统和电力系统稳定器(pss)以及FRC-WT并网变换器及其相关控制器进行了详细的建模，以准确评估FRC-WT对区域间模态振荡的影响。结果表明，在某些模拟场景下，FRC-WTs对区域间振荡有较大影响。
