Relay protection device action constant value optimization method, system and equipment and storage medium

The invention discloses a relay protection device action constant value optimization method, system and equipment and a storage medium, and the method comprises the steps: S1, calculating action constant values cooperating with protection of different sections of an adjacent line, and further confirming the satisfaction conditions of a solution space discrete point sensitivity constraint condition, a selectivity constraint condition, a level difference constraint condition and a power flow constraint condition; s2, optimizing a relay protection constant value by adopting an improved discrete cuckoo algorithm based on the calculated action constant value matched with the protection of different sections of the adjacent line and the satisfaction condition of the sensitivity constraint condition, the selectivity constraint condition, the level difference constraint condition and the power flow constraint condition of the spatial discrete point of the confirmation solution; and S3, outputting the optimized relay
