摘要

为研究风电并网对互联系统低频振荡的影响，基于完整的双馈风电机组模型，定性分析了两区域互联系统在风电机组并网前后阻尼特性的变化情况。从双馈风电机组并网输送距离、并网容量、互联系统联络线传送功率、是否加装电力系统稳定器等多个方面，多角度分析了风电场并网对互联系统小干扰稳定及低频振荡特性的影响。之后，以两个包括两个区域的电力系统为例，进行了系统的计算分析和比较。结果表明，有双馈风电机组接入的互联电力系统，在不同运行模式下，双馈风电机组的并网输送距离、出力水平、联络线传送功率对低频振荡模式的影响在趋势和程度上均有显著差异，这样在对风电场进行入网规划、设计和运行时就需要综合考虑这些因素的影响。

Abstract

In order to investigate the impacts of wind power integration on the low frequency oscillation characteristics of an interconnected power system

the damping performances of a two-area interconnected power system with and without wind power integration are analyzed based on the comprehensive model of the doubly fed induction generator (DFIG). The impacts of several factors

including the DFIG transmission distance

DFIG capacity

tie-line power of the interconnected system

with/without a power system stabilizer (PSS)

on the low frequency oscillation characteristics of the interconnected power system are examined systematically. Then

a two-area four-generator system and a two-area eight-generator system are employed to carry out detailed analysis and comparisons. Simulation results show that the impacts of these factors on the low-frequency oscillation modes are different for various system operating scenarios

and hence it is necessary to comprehensively consider these factors in the plan

design

and operation of wind power integration into an interconnected power system.
