A Modal Analysis of a Two-Area System with Significant Wind Power Penetration •Abstract - This paper presents the results of an investigation aimed at ascertaining the effect that a sizeable wind farm exerts on the oscillation modes of a two-area, four-generator power system. The modal characteristics of the system, when a wind farm replaces one of the generators, are analyzed. Index Terms - Wind turbine generator, wind farm, windpower, small signal stability, inter-area mode, local mode. The results presented in this paper show that for the conditions considered, the WTG does not degrade the twoarea system modal characteristics. The results obtained also show that the inherent characteristics of the WTG lead to the absence of the speed and angle states from the mode shapes associated with the inter-area and local modes. The WTG model used in this investigation is expected to give realistic and correct results when used for bulk system performance studies. Given the rapidly changing nature of this field of modeling and analysis, it is expected that the model components will continue to evolve, in terms of parameter values and structure, as experience and additional test data are obtained. |

两区系统与重大风电穿透模态分析 •摘要 - 本文提出了调查，旨在确定一个相当大的风电场施加在两区，四发电机电力系统的振荡模式的影响的结果。该系统中，当风力发电场替换发电机中的一个的模态特性，进行了分析。 关键词 - 风力发电机组，风电场，风电，小干扰稳定，跨区域模式，本地模式。 本文介绍的结果表明，对于条件考虑，该WTG不会降低twoarea系统模态特性。还获得的结果表明，该机组的固有特性导致缺乏的速度和角度的状态从与区域间和局部模式相关联的模式形状。 预计在本次调查中使用的WTG模型用于群发系统性能研究时，给现实和正确的结果。给定的建模和分析这个领域的迅速变化的性质，因此预计，该模型组件将继续发展，在参数值和结构方面，作为经验和附加测试数据被获得。 |
