摘要

并网风电机组最主要的保护要求之一是孤岛检测和反孤岛保护。本文提出了一种基于异步发电机电流THD的WTs孤岛检测新方法。该方法的新特点是适用于噪声条件下具有大量风力机的风电场和适用于异步型风力发电机。该方法监测发电机电流并计算其总功率，然后根据算法检测wt的状态。利用PSCAD/EMTDC软件对该方法在负载变化、噪声大风、感应电机启动和电容器切换等不同工况下进行了评估。在本研究中，WTs的数据是根据在Manjil站点工作的V47/Vestas风力机的真实数据。

Islanding detection of wind farms by THD

One of the most main protection requirements of grid connected wind turbines (WTs) is islanding detection and anti-islanding protection. In this paper, a new method for islanding detection of WTs based on THD of asynchronous generator currents is proposed. The new features of the proposed method are its application for wind farms with a large number of wind turbines under noisy windy conditions and appropriate for asynchronous type of wind turbine generators. The proposed method monitors the generator currents and calculates their THD then base on an algorithm the status of the WTs will be detected. The proposed method has been evaluated under different conditions such as load changing, noisy windy conditions, induction motors starting and capacitors switching by using PSCAD/EMTDC software. In this research, data of WTs are according to the real data of V47/Vestas wind turbines working in the Manjil site.
