摘要
集电线路是风电场输变电设备主要的组成部分,风电机组通过多条集电线路汇流将电能输送到升压站。集电线路一旦发生故障就会导致风电机组脱网、电网电压波动和机组批量长时间停运,造成不良影响和严重的经济损失,因此集电线路的安全稳定运行非常重要。本文针对某风电场集电线路运行及故障情况,整理以往集电线路多发的故障类型,通过故障原因进行深度分析,总结在故障查找和处理中的一般经验,并提出相应的预防措施。
The collecting line is the main part of power transmission and transformation equipment in wind farm.Wind turbines transmit electric energy to booster station through multiple collecting lines.Once the collector line fails,it will lead to the disconnection of wind turbines,grid voltage fluctuation and long-term shutdown of units,resulting in adverse effects and serious economic losses.Therefore,the safe and stable operation of the collector line is very important.According to the operation and fault conditions of the collector line of a wind farm,this paper sorts out the fault types of the collector line in the past,summarizes the general experience in fault finding and treatment by deeply analyzing the fault causes and put forward the corresponding preventive measures.
