Intelligent substation one-key sequential control checking method and system based on block chain

The invention discloses an intelligent substation one-key sequential control checking method and system based on a block chain, and the method comprises the steps that a block chain server is configured in a region III of an intelligent substation monitoring system, and an access interface is provided for a safe region I; an intelligent substation operator generates a public key and a private keyof each role of each link of the sequential control system through the blockchain server; after one-key sequential control debugging of the intelligent substation is completed, global configuration related to a sequential control system is submitted in a transaction form; in combination with the local sequence control ticket file and the sequence control system global configuration on the block chain, the sequence control host successfully checks the sequence control operation command and sends the sequence control operation command to the anti-misoperation host; in combination with the localanti-error configuration f
