Technical Field

The invention relates to the technical field of power system automation, in particular to a transformer substation switching operation control method, a transformer substation switching operation control system and a transformer substation switching operation control device based on cloud-edge cooperation.

Background

The microcomputer anti-misoperation locking system of the transformer substation becomes a key technical means for preventing electrical misoperation after the development of more than 20 years, and plays a remarkable role in preventing electrical misoperation, ensuring the personal safety of an operation site and the safety of a power grid.

At present, under a switching operation mode of a transformer substation, a command is issued through an OMS (operation management system), operation and maintenance personnel manually write tickets in a PMS (permanent magnet system), the operation tickets are printed after the operation is finished, and simulation preview and voucher operation is carried out on an anti-error host of the transformer substation. However, with the popularization and application of the power grid dispatching operation system of national grid company "one-key sequential control" and "full-flow, full-error-prevention and full-sequential control", the cooperative operation mode of the power grid dispatching end and the station end is more and more common in the power grid regulation and control process, and the following defects in the efficiency of the current transformer substation switching operation error-prevention system are highlighted:

(1) the PMS adopts a manual ticket writing mode, is low in efficiency, and cannot realize the whole processes of order adjustment, ticket operation, rehearsal and operation and online management and control.

(2) The billing and operation rehearsal of the transformer substation anti-error system cannot be realized in a remote workstation, and the interfaces and functions of anti-error products of different manufacturers and different models are not uniform; the intelligent ticket forming function is not provided, and the working efficiency is low.

(3) The transformer substation anti-misoperation system adopts a computer key voucher, so that the step monitoring of a guardian and an operator cannot be realized technically, and meanwhile, the operation display of the computer key is incomplete and not intuitive.

(4) The mode of 'paper operation ticket + recording pen' is still adopted in the on-site operation monitoring, misoperation caused by human factors is controlled by lacking effective means, and electronic, full-flow and online control of operation is lacked. The operation information backfill and the recording are required to be filled on the paper ticket surface and to be filled in by multiple systems.

At present, the safety and error prevention research of switching operation integrated with regulation and error prevention mainly centers on the aspects of error prevention system information acquisition, operation ticket generation, safety and error prevention rule integrated management and the like; however, the current research results lack of a whole switching operation business process and an online support mechanism, so that the problems of error-proofing billing, operation rehearsal, low field operation efficiency and the like still exist; on the other hand, the occurrence of field misoperation and operation leakage accidents cannot be completely prevented from the aspect of the anti-misoperation effect.
