Abstract
A chip-level software and hardware cooperative relay protection device is provided. The device includes: a control chip, wherein a first control unit, a second control unit, and multiple logic circuits are integrated on the control chip; and the logic circuits perform microsecond-level rapid calculation on electrical signals of a protected electrical device, obtain fault feature parameters of the protected electrical device are and transmit same to the first control unit, then perform millisecond-level real-time protection logic determination according to the fault feature parameters of the protected electrical device to obtain relay protection results of the protected electrical device, and protect the protected electrical device by controlling an external relay according to the relay protection results. When the first control unit protects the protected electrical device, the second control unit performs second-level quasi-real-time management communication function processing on operation data generated by the first control unit and the logic circuits.
