Problems solved by technology

[0003] As the proportion of atomic energy units in the power grid continues to increase, once the power grid where the unit is located suffers a serious fault and it is separated from the main grid, it is easy to have high-frequency problems in the local power grid

High-frequency cut-off is the main means to control frequency rise on the grid side. At present, there is no unified setting method. The high-frequency cut-off schemes adopted by each power grid are quite different, and it is difficult to ensure frequency stability in the case of severe excess power in isolated grids.
