Embodiment Construction

[0032] Isolation switch operation is an important part of substation operation and maintenance, but at present the isolation switch is mainly operated by operators on the spot. The monitoring background of the substation performs the opening and closing operation of the isolating switch. For some substations whose equipment is outdated and cannot be operated by the isolating switch in the monitoring background, operators need to manually switch on and off on the spot. With the full development of power grid regulation and control integration and the development needs of unattended substations, in order to reduce the workload of operation and maintenance personnel and improve the efficiency of power grid operation and maintenance, the previous mode of manual operation of equipment is gradually shifting to dispatch control Transition of the remote operation mode on the master side.

[0033] The invention provides a technical solution for remote operation of an isolating switch b...

Abstract

The invention discloses a remote switching operation method based on comprehensive visualization and anti-error topology analysis, and belongs to the field of transformer substation dispatching control. Through the technical scheme, comprehensively visual online monitoring of an isolating switch is combined with a security protection technology based on four-layer anti-error topology, so that the security and reliability of remote operation projects of the isolating switch at a dispatching end are guaranteed. The method consists of two aspects, namely a visual operation mode and four-layer anti-error security assurance. Through the visual operation mode, reliable information assurance is supplied for the operation of the isolating switch, and the state of the isolating switch can be effectively monitored under an unattended condition; and through four-layer anti-error locking, the reliability of the operation is guaranteed, switching misoperation can be effectively avoided, and the security of the operation is guaranteed.

Description

technical field [0001] The invention belongs to the field of substation dispatching control, and in particular relates to a remote operation method for an isolating switch or a grounding switch based on comprehensive visualization and error prevention topology analysis. technical background [0002] Substation remote operation refers to the remote control and remote adjustment of the primary and secondary equipment of the substation at the dispatching control master station, including: substation circuit breaker and isolating switch switching, transformer tap adjustment, backup and automatic switching on / off (backup Automatic switching on / off of power supply), etc., among which the isolation switch operation is an important part of the operation and maintenance of the substation, but the realization rate of the remote operation of the isolation switch dispatching is generally low at present. With the full development of the integration of power grid regulation and control, i...
