摘要

本文介绍了广西某海上风电项目和浙江某海上风场两起海上风电首次送电过程中，开关非正常跳闸的典型案例，广西某海上风电项目开关非正常跳闸的原因是由于合空载变压器产生励磁电流，三相电流值差异较大，造成零序电流超过预设保护值而跳闸；浙江某海上风场是由于长海缆产生的电容与电感匹配，合空载变压器时引起线路串联谐振，造成电流差动保护启动而跳闸，通过对该两起案例的深入剖析，进而采取相应措施避免事故再次发生，对今后海上风电项目顺利投运具有借鉴作用。

Abstract

This paper introduces two typical cases of abnormal switch tripping during the first delivery of offshore wind power stations. Through the in-depth analysis

the reason for abnormal switch tripping in Guangxi offshore wind power station is due to the closing of no-load transformer generates excitation current

three-phase current value difference is large

resulting in zero sequence current exceeds the preset value of the protection; the reason for abnormal switch tripping in Zhejiang offshore wind farm is due to the long cable capacitance

closing the no-load transformer

causing series resonance

resulting in the current differential protection start. Taking proper measures to avoid the accident from happening again. This is a reference for commissioning of future offshore wind power projects.
