The present invention discloses a one-key sequence control automatic test and verification method for an intelligent substation. The method comprises: receiving a sequence control request from a monitoring host; driving a simulated intelligent device control service to respond to the sequence control request according to the pre-configured sequence control logic of an intelligent device; collecting the sequence control logic of the response data obtained by the monitoring host; and comparing the sequence control logic of the response data with the configured sequence control logic of the intelligent device to obtain a test result. The present invention also discloses a corresponding apparatus and system. By using the technical scheme of the present invention, according to the pre-configured sequence control logic of the intelligent device, the simulated intelligent device control service is driven to respond to the sequence control request, the sequence control logic of the response data is compared with the configured sequence control logic of the configured intelligent device, and a test result is obtained according to the comparison result, so that the test is accurate and fast,and the problem of low efficiency of the existing one-key sequence control test is effectively solved.
