Abstract
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.
