摘要
针对某海上风电场一起220 kV线路电抗器匝间保护误动作事件,结合事件过程的复盘和参数分析,确认故障因电抗器保护系统程序定值配置错误引起,并根据设备的保护原理和动作分析提出了具体的应对措施,以避免同类事件再次发生,保障线路正常运行。
In view of a 220 kV line reactor inter-turn protection malfunction event in an offshore wind farm,combined with the review and parameter analysis of the event process,it was confirmed that the fault was caused by the wrong configuration of the reactor protection system program settings,and specific countermeasures are put forward based on the protection principle and action analysis so as to avoid the recurrence of similar incidents and ensure the normal operation of the line.
