介绍了抽水蓄能机组低频保护的概念及国内外抽水蓄能机组低频保护整定的原则,在分析对比该原则的基础上,以宝泉抽水蓄能电站低频保护整定为例,介绍了抽水蓄能机组低频保护整定过程及定值校核计算过程,并对抽水蓄能机组低频保护整定提出相关建议,为国内抽水蓄能电站完成机组低频保护整定提供借鉴。
The concept of low frequency protection of pumped storage units and the principle of low frequency protection setting of pumped storage units at home and abroad are introduced. Based on the comparison and analysis of this principle, taking baoquan pumped storage power station low frequency protection setting as an example, the pumped storage The setting process of low-frequency protection and the calculation process of setting value are analyzed, and some suggestions are put forward for the setting of low-frequency protection of pumped storage units, which can provide references for the completion of low-frequency protection setting of domestic pumped storage plants.
