Abstract

This paper investigates the application of Unified Power Flow Controller (UPFC) to stabilize multi-mode torsional oscillations of sub-synchronous resonance (SSR), and to improve the transient stability during a three phase short circuit fault that may result in oscillatory torques on the generator rotor shaft causing serious damages to the system and may call for the disconnection of a wind farm to avoid any possible damages. Simulation is carried out using MATLAB/Simulink software. Results show that the proposed UPFC controller is very effective in damping all SSR modes of the system under study and in minimizing the potential for the wind farm disconnection during the studied faults. The proposed controller is simple and easy to be implemented.
UPFC在稳定扭振和提高暂态稳定性中的应用
本文研究了统一潮流控制器(UPFC)在稳定次同步谐振(SSR)多模态扭振中的应用,以及在三相短路故障时提高系统暂态稳定性的方法。三相短路故障可能导致发电机转子轴上的振荡转矩对系统造成严重损害,并可能要求风电场断开连接以避免任何可能的损害。采用MATLAB/Simulink软件进行仿真。结果表明,所提出的UPFC控制器可以有效地抑制所研究系统的所有SSR模式,并在研究故障期间最小化风电场断开的可能性。该控制器结构简单,易于实现。
