AI Technical Summary
Existing power grid bus protection methods are unable to accurately determine the source of voltage dip faults in complex power grid environments, leading to misjudgments of fault sources, triggering unnecessary protection actions, and affecting power grid stability.
By collecting data from busbar protection devices within the power grid area, a two-way misconduction relationship analysis and data sharing mechanism is established. Voltage sag source analysis is used to determine whether a voltage sag is a misconduction, ensuring the accuracy of protection actions.
It improves the accuracy and reliability of busbar protection, reduces maloperation, enhances the stability and security of the power grid, and avoids unnecessary protection actions.
