摘要

分析了PMSG风电场集电线路的拓扑结构和故障特征。为了解决传统三段式过流保护在集电线路中存在的问题，结合熔断器的保护特点和永磁同步发电机的工作特性，提出了一种新型的反时过流保护方法。对该保护方法进行了理论分析和仿真验证。结果表明，对于采集线路，新型过流保护比传统的三段式过流保护更好地结合了选择性和速度，具有实用价值。

A novel protection method of collecting power lines in PMSG wind farm

This paper analyzes the topology and faults characteristics of collecting power lines in PMSG wind farm. In order to solve the problems caused by traditional three paragraph overcurrent protection used in collecting power lines, a novel inverse-time overcurrent protection method is proposed based on fuses' protection features and PMSG's (permanent magnetic synchronous generator) operational characteristics. The novel protection method is analyzed theoretically and verified by simulating. Results show that for collecting power lines, the novel protection combines selectivity and speed better than traditional three paragraph overcurrent protection, thus having practical values.
