Embodiment Construction

[0023] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] The substation programmed control system based on integrated five defenses has unique advantages in specific implementation.

[0025] List the operation ticket first, and the work of issuing the operation ticket can be completed in the separate operation ticket system of the substation, or in the integrated five-defense system.

[0026] Then simulate a preview in the integrated five-defense system to ensure that each step of operation satisfies the five-defense logic and form a programmed operation sequence. During the rehearsal, for remote control operations, it is necessary to configure whether to participate in programmed control. Whether a certain step of remote operation participates in program control can be modified during the billing process, but it is fixed and cannot be modified after the billing is completed.

Abstract

The invention discloses an integrated five-prevention operation ticket system-based programmed control system, which is a novel mode for implementing programmed operation of a substation. The system automatically remotely controls the completion of operation items configured to be subjected to programmed control in sequence from operation tickets which have been subjected to simulation preview. In the system, running states of intervals and the operation tickets switched between the running states are not needed to be preset before the commissioning, and the operation tickets are made out before operation. The system allows prestore tickets and heavy load tickets in an operation ticket system framework, so the system also supports various preset soft strap programmed control operations. Meanwhile, the system supports and matches a computer key for field operation. The integrated five-prevention operation ticket system-based programmed control system has the advantages of not needing presetting the running states of the intervals, or presetting the operation tickets switched between the running states, or performing complicated inspection and acceptance work before acceptance of works, and saving programmed control configuration of engineers and the inspection and acceptance work of operating personnel for the programmed control tickets. A part which is required to be remotely controlled manually at a background originally is changed into an automatic execution part so as to accord with a rule of first preview and then operation.

Description

technical field [0001] The invention belongs to the field of power system automation, and more specifically relates to a substation automation system. Background technique [0002] 1. Five-proof operation ticket system [0003] The traditional operation process of the substation is: issue an operation ticket in the five-defense operation ticket system, conduct a simulation preview, and then execute it. According to the task to be performed, a specific operation ticket is issued; the operation ticket is used for the five-defense operation rehearsal, and the five-defense logic is checked during the rehearsal; after the five-defense logic check is passed, the actual equipment operation is performed. The actual equipment operation can be completed remotely in the monitoring system, or it can be transmitted to the computer key, and the operation can be completed on site. [0004] The traditional operation process is formed by accumulating a large amount of practical operation e...
