中文摘要：

风电的接入使得系统由单电源、辐射式结构变成双电源的网络，对配电网原有的继电保护产生较大的影响。本文以PSCAD软件为平台，搭建了含异步风力发电机的风电场和配电网模型，从风电场容量和接入位置两个方面分析了风电场接入对配电网电流保护的影响，得出风电并入配电网对保护的影响并提出解决方案。

英文摘要：

Access of wind power makes the distribution network to change from a single power supply and radiation structure to a network with more than one power supply , and that will have a greater impact on the original relay distribution network .The paper takes the PSCAD software as a platform , builds the models including the asyn-chronous wind-driven generator wind farms model and the distribution network model , and from two aspects of wind farm capacity and access position analyzes the impact of wind farms on the distribution network relay .Then, a con-clusion about the influence of wind power access to the distribution network regarding the relay protection is ob -tained and the corresponding solutions are put forward .
