Abstract

The invention discloses an intelligent inspection system and method for secondary equipment of a 500kV transformer substation, and relates to the technical field of power management. The system comprises a monitoring host, a scheduling end, a communication gateway machine, a station control layer network, spacer layer equipment and a sequential control host which are connected with one another, wherein the sequential control host is connected with the station control layer network and is in bidirectional communication with the station control layer network; the method is based on the equipmentand comprises the steps of S1, soft pressing plate one-key sequential control, the sequential control host initiates station end programmed control, the steps sequentially comprise three steps of S1.1 operation ticket retrieval, S1.2 operation rehearsal and S1.3 operation execution, and manual intervention is carried out through operation cancellation, operation pause, operation continuing and operation ending in the process of flow proceeding. Through the monitoring host, the scheduling end, the communication gateway machine, the station control layer network, the spacer layer equipment, thesequential control host and the like, the safety management and control of the soft strap are realized.

Description

technical field [0001] The invention relates to the technical field of electric power management, in particular to an intelligent inspection system and method for secondary equipment of a 500kV substation. Background technique [0002] Substation "one-button sequential control" operation is an advanced application technology of smart grid. Through the application of automatic control technology, sensing and Internet of Things technology, automatic status identification and intelligent judgment technology, the traditional manual switching which is complicated, repetitive and error-prone The gate operation mode has changed to project software prefabrication, modular construction of operation tasks, automatic identification of equipment status, intelligent verification of anti-mistake interlocking, one-key start of operation steps, and automatic sequence execution of the operation process. Future direction. One-button sequential control is used to operate the substation, and t...
