Description

technical field [0001] The present application relates to the field of electrical technology, in particular to a power-specific algorithm hardware module suitable for power system control and protection devices. Background technique [0002] Each component of the power system needs to be equipped with a relay protection device. When a fault occurs in a designated area of ​​the power system, the relay protection device can disconnect the faulty equipment in a very short time to ensure the normal operation of the rest and avoid large-scale damage. A power outage occurred. The relay protection device performs data collection, communication and fault judgment through the microcomputer system to determine the faulty component and remove it from the power system. With the expansion of the functions of relay protection devices, the requirements for the performance of microcomputer systems, especially the chips in them, are also increasing. [0003] In the current technology, vari...
