摘要
在换流站中,交流滤波器主要用来滤除直流控制系统产生的谐波,以避免对交流输电系统产生不良影响。±500 kV某换流站交流滤波器在投入使用一定年限后,出现了投切频繁、投入时产生较大涌流,以及电容器损坏情况严重等故障。为确保交流滤波器的安全运行,要求供电局必须尽快查找故障发生原因,并及时制定相应的故障解决方案。本文以±500 kV某换流站为例,首先对当前运行中存在的主要问题进行了概述,提出了预防措施和运行过程中的注意事项,对生产现场具有一定的借鉴意义。
In the converter station,the AC fi lter is mainly used to fi lter out the harmonics generated by the DC control system to avoid adverse effects on the AC transmission system.After the AC fi lter of a converter station of±500 kV is put into use for a certain period of time,there are faults such as frequent switching,large inrush current when input,and serious damage to the capacitor.In order to ensure the safe operation of the AC fi lter,the power supply bureau must be required to fi nd out the cause of the fault and formulate a corresponding fault solution in time.The article takes±500 kV as a kind of converter station as an example.Firstly,it summarizes the main problems existing in the current operation,and puts forward the precautionary measures and precautions in the operation process,which has certain reference signifi cance for the production site.
