Remote operation and maintenance method, system and equipment for wide-area substation automation equipment

Abstract

The invention provides a remote operation and maintenance method, system and equipment for the wide-area substation automation equipment. Remote centralized operation and maintenance management and control of the substation automation equipment are achieved through the wide-area operation and maintenance system technology, and the intensive management level of a master station end on substation end equipment is improved; based on a high-performance general service architecture, a three-layer network system including a public service layer, a general service layer and an application service layer is adopted, and servitization of application functions of automation equipment at a transformer substation end is realized; based on key technologies of two-factor login, digital signature, authority authentication and the like, deep safety protection in an integrated full communication process from dispatching to a transformer substation is realized, and the safety of remotely operating transformer substation equipment by a master station is improved; based on a team responsibility area division mechanism, the workload of operation and maintenance personnel of a maintenance team is reduced, and intensive management of the maintenance team on the transformer substation in the responsibility area is realized.

Description

technical field [0001] The invention relates to the field of operation and maintenance systems for substation automation equipment, in particular to a remote operation and maintenance method, system and equipment for wide-area substation automation equipment. Background technique [0002] At present, the operation and maintenance of substation automation equipment is mainly based on the on-site operation and maintenance mode. The research on remote operation and maintenance in China mainly includes the following aspects: (1) Remote operation and maintenance technology based on Modem, using dial-up Modem to search for substation RTU (Remote Terminal Unit, remote terminal unit), realize the remote cold and hot start of RTU, message monitoring and fault diagnosis. (2) Substation RTU and remote channel monitoring system based on GSM (global system for mobile communications) wireless public mobile communication network for data transmission, which can remotely diagnose substation...
