Intelligentized diagnostic system of substation-operation operation tickets

Abstract

The invention discloses an intelligentized diagnostic system of substation-operation operation tickets, which is mainly formed by a maintenance module and an operation ticket generating module, wherein the operation ticket generating module is in communication connection with a database server, and the maintenance module is connected with a device anti-operation logic base in the database server. The device anti-operation logic base comprises a primary device anti-operation logic base, a secondary device anti-operation logic base and a primary / secondary device operation logic base. The operation ticket generating module comprises a picture display unit, a primary device anti-operation logic judgment unit, a secondary device anti-operation logic judgment unit and a primary / secondary device operation logic diagnosis unit. The intelligentized diagnostic system has the advantages that secondary device anti-operation logic added in an operation ticket system has a prompt locking effect on operation of important pressing boards in secondary switching operation and operation of secondary pressing boards related to a primary device state, and accidents of pressing board throwing leakage or throwing errors in an operation process can be effectively avoided.

Description

technical field [0001] The invention relates to a system for generating and managing substation operation tickets, in particular to an intelligent diagnosis system for substation operation tickets. [0002] Background technique [0003] In the daily operation and maintenance of power substation, switching operation is one of the important tasks. The operation includes the operation of primary equipment and secondary equipment such as secondary circuit breakers and protective pressure plates. However, the existing substation operation operation ticket generation management system only establishes the anti-mistake logic library and logical judgment for the primary equipment. The principle of equipment is complex, and substation operators generally do not have a deep grasp of the principles of the secondary aspect, resulting in relatively weak knowledge of the secondary relay protection part; at the same time, the original operating ticket system has no special features for t...

However, the existing substation operation operation ticket generation management system only establishes the anti-mistake logic library and logical judgment for the primary equipment. The principle of equipment is complex, and substation operators generally do not have a deep grasp of the principles of the secondary aspect, resulting in relatively weak knowledge of the secondary relay protection part; at the same time, the original operating ticket system has no special features for the switching of important secondary pressure plates. The alarm signal has no specific anti-misoperation locking means, which is not conducive to the safety protection of the secondary operation of the operating personnel

With the advancement of the "overhaul" mode, operators will be exposed to more and more types of protection devices. It is difficult to guarantee the correct operation of secondary equipment only by relying on the existing primary equipment error prevention conditions. At the same time, there is no The management system aimed at the operation of secondary equipment and the judgment of anti-mistake logic will cause the operator to accidentally turn on and off the relay protection plate during the operation process, which will bring great danger to the safety of production and operators.
