Embodiment Construction

[0029] The present invention is described in detail below in conjunction with accompanying drawing:

[0030] The present invention is divided into two modules: one is the programming system of the anti-misoperation locking rule base, and the other is the anti-misoperation locking operation system.

[0031] 1. The programming system of the anti-mistake locking rule base

[0032] At present, with the development of substation automation technology, the automation system with layered and distributed structure mode of interval-oriented and object-oriented design has become the mainstream. The IEC 61850 standard divides the substation automation system into three levels in terms of logical structure, namely "process level", "interval level" and "station control level". The substation automation system completes its corresponding functions at different levels. The invention adopts the method of combining centralized anti-mislocking at the station control layer and decentralized ant...

Abstract

The invention discloses an anti-operation locking system of a transformer substation automatic system, which is characterized by comprising a programming system and an operation system, wherein the programming system is used for providing functions of management, resource allocation and editing and debugging to the whole engineering and is operated in the operation system; the operation system is used for completing the tasks of input processing, program executing and output processing by explaining the target codes generated by the programming system and is operated in a monitoring system, a communication management unit or a measurement and control device of an upper computer; and the programming system and the operation system perform data interaction through a communication interface. The invention improves the programming efficiency of a logic regulation database of the transformer substation automatic system, reduces the difficulty of follow-up maintenance and management, is convenient to examine, maintain and modify the anti-operation logic regulations, and further strengthens the reliability simultaneously while improving the maintainability of the anti-operation logic regulations of the transformer substation.

Description

technical field [0001] The invention relates to an anti-misoperation locking system for realizing a substation automation system of an electric power system, and belongs to the technical field of electric power automation. Background technique [0002] Prevention of misoperation is an important part of substation operation management. If misoperation occurs, not only the operator may be seriously injured, but also the operating equipment may be seriously damaged, and further power outages may occur, which will affect the power grid. safe operation. In the form of laws and regulations, our country stipulates the principles of management, operation, design and use of electrical equipment for error prevention. [0003] In the substation integrated automation system, in order to prevent misoperation, the system in the station is required to have the anti-misoperation locking function. The common anti-misoperation locking includes mechanical locking, electromagnetic locking, ele...
