摘　　要：风电场多建设在偏僻的山区,地形复杂、交通不便,风电场人员配置较少,员工工作经验少,继电保护人员更少,当风电场出现故障继电保护动作后,由于现场工作人员工作经验较为缺乏,查找故障原因,处理故障需要花费大量时间,导致发电量损失较多。以某风电场一次故障跳闸为例,通过分析保护装置的动作报文和故障录波波形,指导现场运营人员快速找到故障点。Wind farms are mostly built in remote mountainous areas with complex terrain and inconvenient transportation.Wind farms have fewer personnel,less staff work experience,and fewer relay protection personnel.When the wind farm fails,the relay protection action is due to the work of the on-site staff.The experience is relatively lacking,it takes a lot of time to find the cause of the fault and deal with the fault,resulting in a large loss of power generation.Taking an example of a fault trip in a wind farm,by analyzing the action messages of the protection device and the fault recording waveform,it can guide the on-site operators to quickly find the fault point.
