Problems solved by technology

At present, the return of secondary equipment and the implementation of safety measures still adopt the traditional operation ticket form, and manual return and check are carried out one by one. This method is inefficient and error-prone.
Moreover, the current substation sequence control operation is mainly aimed at the running state, and there are few studies on the operation sequence control of the protection device.

Embodiment Construction

[0048] The present invention is described in detail below in conjunction with accompanying drawing:

[0049] A one-button sequential control method for an intelligent substation protection device, comprising the following steps:

[0050] (1) The soft pressure plate of the intelligent substation protection device is uniformly named and defined according to the standard rules, and the soft pressure plate is standardized;

[0051] The soft press plates are named and defined according to the standard rules, and the whole station is unified to avoid misoperations caused by operators’ understanding errors due to different naming methods of similar soft press plates.

[0052] The screens of each interval are arranged according to a unified standard. The functional soft pressing plate is distinguished by a yellow mark, and the export soft pressing plate is distinguished by a red icon. explain. In view of the fact that the management of the soft clamping plate of the intelligent stat...

Abstract

The invention discloses a one-key sequential control method for an intelligent transformer substation protection device, proposes the sequential control for the protection device, achieves the one-keysequential control of switching protection and safety isolation, and effectively reduces the risk of misoperation in the safety measure process through the fixing of the switching step of the protection device. The above technical scheme of the invention is implemented at one 220kV intelligent transformer substation, and the operation state is better, thereby greatly improving the intelligentization level of the transformer substation.

Description

technical field [0001] The invention relates to the technical field of online operation and maintenance of secondary equipment in intelligent substations, in particular to a one-button sequential control method and system for a protection device in an intelligent substation. Background technique [0002] In recent years, the development of communication network technology has created conditions for the application and promotion of smart substations, which has continuously improved the intelligence of substations. The smart substation replaces the hard wiring of the traditional substation with three layers and two networks, creating good technical conditions for the maintenance and status monitoring of relay protection equipment. [0003] The smart substation replaces the hard wiring of the traditional substation through optical fiber communication. The traditional secondary circuit wiring is expressed as an invisible abstract network message, which increases the workload of ...
