A measurement and control device and its logic display method for preventing false locks

Abstract

The present invention relates to a measurement and control device and a misoperation-preventive locking logic display method thereof, which belong to the technical field of power system protection and automation. The method of the invention firstly determines the misoperation-preventive locking logic according to a misoperation-preventive logic rule base; then, the determined misoperation-preventive locking logic is loaded into the measurement and control device; the measurement and control device identifies the received misoperation-preventive locking logic and marks it with an OR gate logic, and the corresponding logical expression is split into at least two parallel sub-logical expressions; and finally the contents of the sub-logical expressions obtained are graphically displayed. The method of the invention can display the blocking logic diagram in real-time on the measurement and control device so as to make the engineer intuitively, conveniently and real-time determine whether the blocking logic result reflects the actual working condition of the equipment layer and to facilitate the debugging progress of the automation project of a substation.

Description

technical field [0001] The invention relates to a measurement and control device and an anti-misoperation locking logic display method thereof, belonging to the technical field of power system protection and automation. Background technique [0002] Prevention of misoperation is an important content of substation operation management. If misoperation occurs, not only the operator may be seriously injured, but also the operating equipment may be seriously damaged, which may further cause power outage accidents. [0003] In order to effectively prevent personal and major equipment accidents caused by misuse of electrical equipment, my country put forward the requirements of five preventions for electrical equipment as early as 1990, and stipulated the principles of management, design and use of electrical misuse prevention in the form of regulations. The principle that the design of the anti-misoperation device should be followed is: all high-voltage electrical equipment that ...
