摘要
本文对换流站站用电系统400V断路器保护定值整定原理进行说明,并结合现场实际给出整定计算的方法。以此来优化提高各换流站400V断路器上下级保护配合,并提高断路器的可靠性,减少其误动、拒动的可能性。
Based on practical engineering experiences, typical setting principles of the 400V breaker of the converter station service power system are analyzed in this paper, and the setting calculation method is also summarized, hoping it is helpful to the settings of the converter station service power system in future HVDC projects.
