An oscillating disassembly device can be used to divide the power grid into several parts. Currently, this device has not been adopted by yibin bureau. If a large unit is cut off in a short time, the active power in the power grid will be seriously unbalanced, and the frequency will be rapidly reduced, thus leading to the frequency collapse of the entire power grid. In order to avoid such power grid accidents, it is necessary to use low-cycle load reducing device preset frequency to gradually cut off each load in several rounds until the active power balance and the frequency returns to normal.
