Wherein, distinguish color and comprise that color, transformer current when color, transformer current when transformer current normal condition color, transformer current approach 0.8 times of out-of-limit numerical value exceedes 1 times of out-of-limit numerical value exceedes the color of out-of-limit numerical value when more than 2 times;
In electric network wiring scheme, refresh in real time the current monitoring situation of each transformer station, distinguish to distinguish color respectively, in the time of selected certain transformer station of terminal user, eject messagewindow, show the real-time current situation of all transformers in this transformer station, amplification is provided simultaneously, dwindles, the function of translation and intercepting electrical network line graph;
Curve index: all transformers are represented by affiliated unit and the grouping of affiliated transformer station, according to selecting screening to show each substation site, select transformer station to enter time/current curve of checking all transformers in it, time/current curve comprises real-time curve, history curve, diurnal curve, across time step curve; In addition, can adjust coordinate axis, add, delete curve, curve color and background color is set, curve numerical value and sectional drawing are exported in EXCEL;
Statistical report form: inquiry and two kinds of report generation modes of manual typing are provided; When inquiry, select inquiry period, these information of transformer, inquire about completely, in the electric network wiring scheme embedding, by the electric current of the each transformer station of differentiation colour code the setting in advance situation of crossing the border, and derived query result data and wiring diagram are in EXCEL.
7. transformer neutral point DC current management monitoring system according to claim 6, the rendering algorithm that it is characterized in that described electric network wiring scheme is: the each element in electric network wiring scheme adopts from the method for painting and completes graphic plotting, in the time that changing, certainly paints once element oneself state, without whole figure is refreshed.
