摘要:

随着大规模风电并网,风电机组与同步机组间的动态交互加剧,前者对电网低频振荡(low-frequency oscillation,LFO)的负面影响和正面控制效果渐趋显著。文章对双馈风电机组(doubly-fed induction generator,DFIG)并网系统LFO抑制问题展开调研。分析了DFIG并网对LFO的影响机理,从风电侧和电网侧比较了LFO抑制措施。重点讨论了DFIG附加功率振荡阻尼器(power oscillation damper,POD)的参数整定方法和控制策略设计。对基于传统方法、优化方法、鲁棒理论等参数整定方法,以及线性二次型调节器(linear quadratic regulator, LQR)、自抗扰控制(active disturbance rejection control,ADRC)、滑模变结构控制(sliding mode control,SMC)、模糊控制等控制策略进行比较分析。最后对DFIG并网电力系统低频振荡抑制问题,给出后续研究展望。

Abstract:

With large-scale penetration of wind power into power systems, the dynamic interaction between wind power generators and synchronous generators is intensified. The negative impact and positive control effect of wind power generators on the low-frequency oscillation (LFO) in power systems is increasingly obvious. This paper investigates the LFO damping in power systems with doubly-fed induction generators (DFIGs). The mechanism of DFIG influencing the LFO is described. The damping measures from the wind farm or power system are compared. LFO damping strategies with parameter tuning and control strategy design to the DFIG power oscillation damper (POD) are discussed. The parameter tuning based on traditional methods, optimization, robust design, etc., are compared. And the control design methods such as linear quadratic regulator (LQR), active disturbance rejection control (ADRC), sliding mode control (SMC), fuzzy control are also compared. Suggestions to the future research on the LFO damping in DFIG integrated power systems are given.

Key words: doubly-fed induction generator (DFIG), integrated power system, low frequency oscillation (LFO), power oscillation damper (POD), parameter tuning, control strategy
