The Substation Online Five Anti-system Software Design And Research

Substation exists personnel or equipment caused by misuse, accident more huge losses, to carry out research on the substation-line system of five anti important role to ensure that the substation safe and stable operation.The software of the substation Online five anti-system which has been developed to the stage based on graph-billing is an important part of the whole system as the human-computer interaction interface. However, it has some problems. For instance, graphical modeling method is cumbersome and inefficient, system maintainability is low and the speed of automatically generate logic rule base is also slow. This paper mainly does the in-depth studies about the graphics-oriented object modeling method, string matching algorithm in a framework network environment and the Boolean matrix algorithm under the environment of Reachability matrix generate method.The paper first studies the graphics-object oriented modeling method combined with the Visual Graph platform (VG foundation modeling method) and the defects of the method’s application performance. Then the paper proposes a power graphics-object oriented modeling method combined with Visual Graph optimization platform (VG optimization power modeling method). After that, through the experiments, the paper compares the efficiency and application performance of VG optimization power modeling method and other three modeling methods.Secondly, the paper studies the a method based on frame theory combined with WBM algorithm to improve the system maintainability of the substation Online five anti-system. Then it introduces the framework for network to the substation Online five anti-system and self-optimizes. Further more, this method analyzes and promotes an improved BM algorithm oriented the substation Online five anti-system—WBM algorithm. And then, through experiments, the paper compare the improvement effect to the system maintainability of this method with the other five methods one of which is an original framework for network combined with BM algorithm. At the same time, the paper integrates the method into the oriented object language VC++to achieve.The paper also studies a Boolean relay matrix algorithm to improve the speed of automatically generation of logic rule base. Firstly, the paper builds an environment for automatically generated the substation Online five anti-system logic rule base based on the Reachability matrix generation method——Boolean relay matrix. And then put the algorithm into the environment of Reachability matrix generation method, compare the generation logic rule base’s computation time, the range of applications and operational stability of this algorithm with those of Boolean matrix algorithm and Boolean matrix improvement algorithm through experimental methods.Finally, this paper designs the substation Online five anti-system’s application program combined with these three methods, including a database,drawing management, soft-ware interface and initialization, login user management, operation ticket management, logic rule base is automatically generated, historical data save and inquire.The substation Online five anti-system’s application program achieved in this paper is proved by experimental comparison. It improves the efficiency and performance of the system graphical modeling, and also improve the maintainability of the system, accelerating the speed of logic rule base generation.
