Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] Example of display method
[0025] The method of displaying the main wiring based on the switch-on / off state of the branch in the smart substation, the steps are as follows:
[0026] Detection step: detecting the state of the branch CT or the branch SV receiving the soft pressure plate;
[0027] Judgment steps: If the CT primary value of the branch is zero or the SV receiving soft pressure plate is in the exit state, the corresponding branch module is in the exit state, and the control state of the corresponding branch module is not set; otherwise, the corresponding branch is in the input state, and the corresponding branch is set. The control state of the branch module;
[0028] Displaying step: detecting the control state, and displaying the branch module corresponding to the set control state in the main wiring diagram.
[0029] The above method ...

The invention relates to a branch entry and exit states based display method and an apparatus for main lines in a smart transformer station. The method comprises the following steps: a detection step, a determining step and a display step. In the detection step, the states of a branch CT or a branch SV receiving soft pressing plate are detected. In the determining state, if the primary value of the branch CT is zero or if the SV receiving soft pressing plate is in an exit state, the corresponding branch module is indicated to be in an exit state too, and the non-set position corresponds to the control state of the branch module. Otherwise, the corresponding branch is indicated to be in an entry state and the set position corresponds to the control state of the branch module. In the display step, the control states are detected so that the branch module corresponding to the control states can be displayed with positions in a drawing for main lines. According to the invention, the apparatus is based on an embedded system, utilizes the entry state of a branch, fully considers the practical engineering application, and adopts a dynamic display mode for main lines. The crystal display device of the apparatus only displays branches in service while automatically shielding those out of service, so that operators can check the information on display about the main lines conveniently. Further, the interface is also compact and good looking.
Description
technical field [0001] The invention belongs to the field of intelligent substations, and in particular relates to a method and device for displaying main wiring based on the switch-on / off state of branch circuits. Background technique [0002] The main wiring forms of the primary system in the substation are various, the number of access branches is different, and there are various operation modes such as branch switch switching, bus switching, and bus interconnection. [0003] In the traditional main wiring display mode, the busbar protection device is displayed according to the largest branch circuit that can be supported. There are many display pages, and the data display content is limited and crowded. Since only a part of the branches will be put into operation in a specific project, it is impossible to visually judge which are the operating branches that are put into use and which are the out-of-service branches that are not put into use from the main wiring diagram o...
