The invention discloses a
sequence control system and method for the switching operation of a
transformer substation. By taking the operation project
software prefabrication, operation task module construction,
equipment state automatic judgment and anti-misoperation
interlocking intelligent check as the main characteristics, a one-key
sequence control function of one-key starting of operation steps and
automatic sequence execution of an operation process is realized based on an operation process of task generation,
simulation rehearsal and instruction execution. According to the scheme, during the switching process of the
transformer substation, by the operation project
prefabrication, the invoicing and approval links of the field work tickets are avoided, the management cost is reduced,and the operation tasks are built modularly, and the application range of the
sequential control operation mode is expanded. Through the
equipment state automatic identification and the anti-
error checking, the
workload of operators is reduced, and the operation process is simplified. Through the use of two sets of anti-misoperation systems, the anti-misoperation capability is improved; and the operation process is started by one key and is automatically executed, so that the operation efficiency and safety of the disconnecting link of the
transformer substation are greatly improved, and the very high application value and popularization significance are achieved.
