The Research And Development About The Visualization Of The Substation Main Wiring Reliability Evaluation Process

In order to combined the main electrical wiring reliability calculation andDrawing of power system perfectly, this paper studies a set of programs to calculatethe reliability which uses VB6.0as development platform, calles Visio DrawingControl controls for graphical. In terms of the main wiring graph drawing, if simplyusing development tools such as VB, VC, Delphi directly developing the graphicwhich will not only greatly increase the workload of development, at the same timebut also not conducive to the maintenance of late. Secondary development based onVisio Drawing Control controls and using VB to simply call this Control can achievestrong Drawing function, the method greatly reduces the complexity of the substationmain wiring Drawing program, make it relatively easy to make the development ofpower system Drawing program.This paper first introduces the meaning of the substation main wiring reliabilityevaluation and its development present situation, in particular, in the aspect ofdrawing instructions; Lists several typical form of substation main wiring, and itsoperation mode and a disadvantage; Focusing on Visio Drawing Control Control forsecondary development, especially in the development of mold, developed a set ofmain wiring which can draw various forms of interface; Substation main wiringreliability calculation method and the evaluation model are proposed; On this basis,using VB which supports Drawing Control ActiveX Control, that can write acalculation of the main electrical wiring in the form of VB program, the program canautomatically find each node of the main wiring number, can automatically identifyall kinds of wiring topology structure, can easily input raw data in the graphical, thencalculate reliability parameters of the main wiring. Finally, citing several typical mainelectrical wiring, and verifying the correctness of the program.Thus, we explore the practicability and extensibility of the program, and instructthe shortcoming of the program, and look ahead of the prospect of the program. Theuse of this method make the Visio drawing embedded to VB interface and make thesystem controllability of graphics stronger.
