    Abstract: This paper took the sequential tripping action of the low-frequency and low-voltage load shedding device and the reserve power automatic input protection device in a 110 kV substation as an example. It proposed optimization measures of the logic of action to reduce the impact on the power system and network load and promote reliable and stable operation after analyzing the logical sequence of the sequential tripping action of the low-frequency and low-voltage load shedding device and the reserve power automatic input protection device based on information from substation monitoring reports, an action record of the protective device, the power flow distribution, etc. It also proposed optimization measures of the logic of action to reduce the impact on the power system and network load and promote reliable and stable operation.
    Key words: substation; low-frequency and low-voltage load shedding device; reserve power automatic input protection device
