A visualization analysis of the functional requirements and check system for anti-misoperation blocking logic in a substation is designed and applied. It is based on an intelligent monitoring platform. The system realizes the graphical display and the real-time checking result display for the primary equipment on a monitoring wiring diagram. At the same time, it can realize the visualization of the whole station anti-operation blocking logic rules and an integrated simulation check. The online simulation supports both graphic and manual display. Different sizes of graphics canvas required by different logic rules present a problem. Thus an adaptive layout algorithm for a visual logic diagram is proposed to realize the adaptive layout display of different logic rules. Finally, the result of engineering application is given. The system deepens the functional application of anti-misoperation blocking logic on an intelligent monitoring platform, and provides a convenient means for corresponding engineering debugging and acceptance.
