Multiple emergency area during with the electrical network complex fault is divided into different accident subregions, to information analyses such as the upstream and downstream of each accident subregion, corresponding trip switch, regional trend, zone loads, and according to the priority displaying of operate time of the relevant trip switch of accident subregion.
4, accident is judged and decision-making module
Utilize the static security analysis principle, carry out N-1 and cut-off analysis, lsafety level and the state of analytical system after accident.
5, network automatic closing module
To the accurate judgement of the power failure state of target bus or load and to target be non-fault zone (judgement, when satisfying operation condition, the console switch of correspondence is included in the series of operations control according to the order that defines, remote control is carried out.
6, electrical network single-phase earthing discrimination module
Automatically monitor busbar voltage, when judging the suspicious single-phase earthing of bus, system searches out the associated switch of this bus automatically, carries out switch by the dispatcher according to certain priority and divides closing operation according to the order of sequence, determines suspicious ground connection outlet fast.
7, try the drawing-die piece automatically
According to the switch changed position situation, by the network topology analysis, failure judgement power failure scope, and nature of occurence.
8, electrical network subregion topology coloring module
Sheet net trend intelligent analysis with represent instrument, mainly the radial electrical network towards the area adopts tree, INTELLIGENT IDENTIFICATION goes out the supply district of 220KV transformer station.
Can offer the dispatcher in the reference of scheduler routine operation aid decision by above-mentioned design, can make dispatching of power netwoks rise to " automated intelligent type " scheduling by present " manual analysis type " scheduling.Be implemented in the opportunity of combat that in emergency circumstances avoids delay, safety and catastrophe problem were eliminated in the stage of breeding, and then prevent the generation of large area blackout.
