Abstract

A Doubly Fed Induction Generator has a stator winding directly coupled with grid whereas rotor is to the grid via a fault-prone converter. In early times, when a fault occurred, these generators were required to disengage from the grid. However, due to the increased penetration, grid operators demanded WTs remain connected to the grid. Thus, this paperwork integrates crowbar protection with a Battery Energy Storage System (BESS) to improve Fault Ride Through (FRT) capability. For performance evaluation under transient conditions, a three-phase symmetrical fault is imposed at a time of 2 seconds. By using the suggested technique, the DC-link voltage is observed to improve and remain at 1150 V with minor fluctuation. Likewise, the stator and rotor currents are observed to remain at their nominal value after 2.15 seconds. MATLAB-Simulink software is used for modeling and simulation by obtaining all the system’s actual parameters from ADAMA-II Wind Farm.

通过性能调查分析基于双馈感应发电机的风力发电系统的故障穿越

双馈感应发电机的定子绕组与电网直接耦合，转子绕组通过易发生故障的变流器与电网相连。在早期，当故障发生时，这些发电机被要求脱离电网。然而，由于渗透率的增加，电网运营商要求wt保持与电网的连接。因此，该文件将撬棍保护与电池储能系统(BESS)集成在一起，以提高故障穿越(FRT)能力。对于暂态条件下的性能评估，在2秒的时间内施加一个三相对称故障。通过使用建议的技术，观察到直流链路电压有所改善，并保持在1150 V，波动很小。同样，观察到定子和转子电流在2.15秒后保持在其标称值。利用MATLAB-Simulink软件进行建模和仿真，从ADAMA-II风电场获取系统的全部实际参数。

期刊介绍： Having been in continuous publication since 1977, Wind Engineering is the oldest and most authoritative English language journal devoted entirely to the technology of wind energy. Under the direction of a distinguished editor and editorial board, Wind Engineering appears bimonthly with fully refereed contributions from active figures in the field, book notices, and summaries of the more interesting papers from other sources. Papers are published in Wind Engineering on: the aerodynamics of rotors and blades; machine subsystems and components; design; test programmes; power generation and transmission; measuring and recording techniques; installations and applications; and economic, environmental and legal aspects.
