Referring to fig. 3, a schematic diagram of a trip interface (corresponding to a trip monitoring unit) of the present application is shown.
In the tripping interface, tripping events are divided into four types of switches, circuits, buses and main transformers. In each type of display, the voltage levels are preferably arranged from high to low, and the same voltage level is arranged in time sequence.
The decision process of the four types of trip logics is as follows:
(1) tripping a switch:
when a switch protection action is accompanied by switch displacement, the switch is judged to be tripped. For the tripping of the 10kV lines of the distribution network, the tripping belongs to the switch tripping category, and the opposite side does not need to be considered, so that a switch tripping event can be generated for any 10kV line as long as a protection action signal and a switch are shifted.
(2) Line tripping
Tripping a main network conventional line: according to the fact that the name of a trip line is used as an identification basis, when a certain line trips, accidents with the same line name and protection action signals and switch deflection conditions in the same time range are combined into a trip item through retrieval, and specific accident information is checked through clicking details.
Tripping of the main network T connection line: and storing all T-connection line information in the main network tidal current diagram in the library, and automatically searching whether protection action signals and switch displacement conditions exist in each side within the same time range when T-connection line tripping occurs. If yes, the trip events are automatically combined into one trip event, the specific event can be checked by clicking the details, and the key information, namely time, station name, equipment and the like, is still displayed according to the accident module in the specific event.
And (3) line tripping zone connection and disconnection conditions: the method comprises the steps that line information with the linkage cutting condition is stored in a warehouse, when a specific line trips, the corresponding linkage cutting line condition is automatically searched within a certain time range (according to protection linkage cutting time), and if corresponding switch deflection exists, the linkage cutting module is displayed.
(3) Tripping of a main transformer:
when main transformer main protection action (differential protection, heavy gas protection) is carried out and simultaneously each side switch of the main transformer is displaced, the main transformer tripping event is judged.
(4) Bus trip
And (3) bus self protection actions (busbar differential protection and failure protection), and when the switch of the connected line interval on the section of bus is shifted and the line interval protection information is not available, the bus is judged to be tripped, and the X bus differential correspondingly searches the busbar connection switch and the line switch on the X section of bus. In addition, if a certain 220kV bus has a long trip condition, when the certain 220kV bus trips, the interval condition of the opposite sides of the line connected with the certain bus is searched, and if the switch is shifted and the related protection condition exists, the trip event of the same bus is merged.
And the main transformer middle backup protection and the main transformer low backup protection act, and a bus trip event is judged when a bus branch or a main transformer middle and low voltage side switch is shifted.
And the association key in the accident information column can be linked to the accident interface to view detailed accident information, and the link is identified according to the field. For example, if the xxx line of the 110kV canadian line trips, the correlation of the "canadian" field is recognized, and then two records of the xxx switch fault signal of the 110kV canadian line of the canadian line and the xxx switch fault signal of the 110kV canadian line of the city are marked in red for being convenient to view.
