摘要
直流谐波保护在直流保护中属于后备保护,在实际运行过程中发生直流谐波保护动作的概率较低,本文结合柴达木换流站两次直流谐波保护动作跳闸情况,在介绍直流谐波保护原理的基础上,对保护动作情况进行分析,并提出一些改进建议,对现场运行维护人员提供一定的指导作用。
HVDC harmonic protection is a back-up protection in HVDC protection,the low probability of the HVDC harmonic protection action in the actual operation. In this paper,the author analysed the reason and process of HVDC harmonic protection which had happened twice in Qaidam Converter Station,and introduced the principle of the HVDC harmonic protection, Some improvement suggestions are presented, which provide some guidance for the operation and maintenance personnel.
