Specific embodiment
A kind of 10kV distribution line pre-operation method, comprises the steps：
The some equipment in the primary connection figure of electrical network and electrical network are stored in components database.
According to selected equipment, components database is searched described equipment and the circuit being connected with this equipment.
Judge described equipment and the electriferous state of the circuit being connected with this equipment, if electriferous state is identical, components database is searched the miscellaneous equipment with described connection, then proceeds to previous step；Otherwise stop searching, obtain pre-operation control figure.
Electriferous state identical equipment in pre-operation control figure and circuit are shown with same color.
The present invention includes equipment live condition adjudgement and equipment operation prompting, two functions of displacement, interacted with components database by pre-operation control figure and judge step by step, by from same power supply status closing the equipment of position, circuit is all changed into same color, the state that prompting frame shows neighbouring device is ejected, operated equipment and subordinate equipment state make corresponding change during equipment operation.The present invention is the operable graphical interfaces being drawn based on visual studio program development software (PDS).
As shown in figure 1, equipment live condition adjudgement function：S101, in components database find pre-operation in figure power supply point.S102, find the line-outgoing equipment that this power supply point is connected in components database.S103, the record according to components database, judge the division state of line-outgoing equipment.If S104 equipment, in a point position, stops, EP (end of program).If S105 equipment is closing position, continue to find the circuit that equipment is connected in components database.S106, the circuit being found is transformed to the color consistent with power supply point and equipment, represents and be derived from same power supply.S107, find the other elements that this circuit is connected in data base.If S108 is not connected to other equipment, stop, EP (end of program).If being connected to other equipment, return S102 step.
As shown in Fig. 2 carrying out the process that " conjunction " operates.The element of described below, namely some equipment in electrical network, including on-load switch, car switch and disconnecting link etc..S201, judgement are currently needed for the state of operation equipment.If S202 has been to close position, points out and stop.If S203 point of position, then collect neighbouring device status information, and give to point out.S204, user determine whether to carry out closing bit manipulation, if it is not, then stopping.S205 if it is determined that will carry out closing bit manipulation, then checks whether this equipment both sides is powered.If S206 is simultaneously powered, judge that the equipment that need to operate is switching station's equipment or line facility；If only powered on one side, put this equipment（It mostly is all kinds of switches）For closing position state.If S207 switching station equipment, then by this equipment（It mostly is all kinds of switches）It is set to conjunction position state；If line facility does not then allow to be operated（Because common line line facility current-carrying capacity is different, cyclization easily causes apparatus overload）.S208, from the beginning of this equipment, find and the circuit of this equipment UNICOM and in the equipment closing position, putting its state is electriferous state.
As shown in figure 3, carrying out the process of " dividing " bit manipulation.S301, judgement are currently needed for the state of operation equipment, including switch, disconnecting link, car switch, on-load switch；If being a point position, pointing out and stopping.If S302 closes position, then collect neighbouring device status information, and give to point out.S303, determine whether to carry out a point bit manipulation, if it is not, then stopping.S304 if it is determined that a point bit manipulation will be carried out, then searches the affiliated power supply of this equipment, calculates by power supply, and when calculating current device, putting its state is point position.S305, judgement are switching station's equipment or line facility.If S306 line facility, then continually look for the All other routes of subordinate and the equipment being connected with equipment, putting them is without electricity condition.If S307 switching station equipment, judge whether that both sides are simultaneously powered.If S308 both sides are simultaneously powered, then change the subordinate equipment electriferous state being attached thereto（Color change）.If it is not, then returning S306 step.
