Embodiment
A kind of 10kV distribution line pre-operation method, comprises the steps:
To some equipment of storing in components database in primary connection figure and the electrical network of electrical network.
According to selected equipment, in components database, search described equipment and the circuit with this equipment connection.
Judge described equipment and the electriferous state with the circuit of this equipment connection, if electriferous state is identical, in components database, searches and the miscellaneous equipment of described connection, then proceed to previous step; Otherwise stop searching, obtain pre-operation control chart.
The equipment that in pre-operation control chart, electriferous state is identical and circuit are shown by same color.
The present invention includes the judgement of equipment live state and equipment operating prompting, two functions of displacement, by pre-operation control chart and components database judgement step by step alternately, to all become same color at equipment, the circuit of co-bit from same power supply status, when equipment operating, eject the state that prompting frame shows neighbouring device, operated equipment and subordinate equipment state are made corresponding change.The present invention is the operated graphical interfaces drawing based on visual studio program development software (PDS).
As shown in Figure 1, equipment live state arbitration functions: S101, in components database, find the power supply point in pre-operation figure.S102, in components database, find the line-outgoing equipment that this power supply point connects.S103, according to the record of components database, judge deciliter state of line-outgoing equipment.If S104 equipment stops in a point position, EP (end of program).If S105 equipment, in co-bit, continues the circuit that searching equipment connects in components database.S106, found circuit is transformed to the color consistent with power supply point and equipment, represents from same power supply.S107, in database, find other elements that this circuit connects.If S108 is not connected to other equipment, stop EP (end of program).If be connected to other equipment, return to S102 step.
As shown in Figure 2, carry out the process of " closing " operation.The element of the following stated, is also the some equipment in electrical network, comprises on-load switch, car switch and disconnecting link etc.S201, judge the current state that needs operating equipment.If S202 has been co-bit, points out and stop.If S203 point of position, collects neighbouring device state information, and points out.S204, user determine whether to carry out co-bit operation, if not, stop.To carry out co-bit operation if S205 determines, check that whether these equipment both sides are charged.If S206 is simultaneously charged, the equipment that judgement need operate is switching station equipment or line facility; If only have one side charged, putting this equipment (mostly being all kinds of switches) is co-bit state.If S207 switching station equipment, is set to co-bit state by this equipment (mostly being all kinds of switches); If line facility does not allow to operate (due to common line line facility ampacity difference, cyclization easily causes apparatus overload).S208, from then on equipment starts, and finds with the circuit of this equipment UNICOM with at the equipment of co-bit, and putting its state is electriferous state.
As shown in Figure 3, carry out the process of " dividing " bit manipulation.S301, judge the current state that needs operating equipment, comprise switch, disconnecting link, car switch, on-load switch; If be a point position, point out and stop.If S302 co-bit, collects neighbouring device state information, and points out.S303, determine whether to divide bit manipulation, if not, stop.To divide bit manipulation if S304 determines, search the affiliated power supply of this equipment, be started to calculate by power supply, while calculating current device, put its state for a point position.S305, judgement are switching station equipment or line facility.If S306 line facility, continues to find All other routes and the equipment of the subordinate that is connected with equipment, put them for electriferous state not.If S307 switching station equipment, judges whether that both sides are simultaneously charged.If S308 both sides are simultaneously charged, change the subordinate equipment electriferous state (change color) being attached thereto.If not, return to S306 step.
