Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed description.
The closed loop control method of a kind of power scheduling operation order and ground wire operation; It is utilization network topology technology; Through the dispatcher operation order is ordered, returned and to make process carry out ground wire hanging, tear open prompting, realize ordering and the synchronous interaction management of ground wire management, help dispatcher's intelligent decision the whole network ground wire state of living in; The whole network ground wire is hung the situation of tearing open carry out integral body, prevent the generation that mistake is hung, mistake is torn accidents such as ground wire open control.The closed loop control method of this power scheduling operation order and ground wire operation coordinates through power network topology figure module, scheduling grid switching operation process module and ground wire operational administrative module that control realizes.Wherein, the power network topology figure module is mainly used in electrical network graphical modeling and displaying, for the ground wire management provides the network topology analytic function; Scheduling grid switching operation process module is mainly used in and generates the scheduling grid switching operation bill, and the operation dispatching operational order orders, return and make function; Ground wire operational administrative module is used to analyze the priority operating sequence of ground wire operation and scheduling operating command, and orders in the operation order, carries out the ground wire operation before returning order and remind with state.
The closed loop control method of a kind of power scheduling operation order and ground wire operation may further comprise the steps:
1, the power network topology figure module carries out modeling and shows the modeling figure according to electrical network primary connection figure.
The electrical network figure module is an electrical network graphic plotting and a management type platform based on data integrated technology of picture library and topology model construction technique construction, supports once, secondary device graphic plotting and demonstration; Modeling can be simulated the actual physical attribute of each equipment, handles five anti-rules automatically.
The power network topology figure module carries out modeling according to the primary connection figure to different equipment simulating actual physical attributes, but the circuit breaker turn-off current, and isolating switch can be realized obvious interruption intervals; Bus can compile, distributes and transmit electric energy; Generate figure as shown in Figure 1 after the modeling; Circuit breaker and isolating switch black shade are represented closure state, and the blank expression of white off-state, the mode of connection are that double-bus adds other maternal formula; 252 circuit breakers and 251 circuit breakers and both sides isolating switch be at closure state, and pocket encloses I road and half pocket line at run mode.
2, scheduling grid switching operation process module is touched figure generation and operation dispatching operational order according to building.
When needs overhauled circuit, scheduling grid switching operation process module generating run was ordered, and for example dispatched the grid switching operation bill order and was " half pocket line, 252 circuit breakers are changeed maintenance ", and the operation dispatching operational order orders and time order operation then.Order in scheduling, return to make in the process ground wire is articulated, removes extension that prompting depends on topology and the five anti-rule judgment ground wires of scheduling grid switching operation order to equipment, electrical network primary connection figure, tears demand open, and in figure, remind.
3, the ground wire administration module is when the power network topology figure module carries out simulated operation; Analyze the electric network state of electric grid operating front and back; On safety analysis result's basis, carry out the prompting of hanging earthing conductor operation; And the current state of record ground wire, return when making when operational order and again the dismantling operation of ground wire to be pointed out.
As shown in Figure 2, when carrying out the hanging earthing conductor operation, ground wire operational administrative module is analyzed according to power network topology operational order (inspection operation order) is resolved to operation order item by item, and carries out the electrical network simulated operation; In the simulated operating procedure through to electric network state before operating and the state comparative analysis of operation back: when reaching the maintenance condition, at first need 252 circuit breakers be broken off, draw back 252 circuit breaker both sides isolating switches then.Processing safety is analyzed after the EO, intelligent decision goes out at 252 circuit breaker both sides hanging earthing conductors, ejects with the dialog box window form then, and the prompting dispatcher needs hanging earthing conductor, need with field verification ground wire current state, just can construct.When inspection operation orders to finish, hanging earthing conductor, reach the maintenance condition after, electric network state is as shown in Figure 3.
When site operation finishes; Scheduling operation order is returned when making the dispatcher for " with 252 circuit breakers transhipment row ", and through same analytical work, ground wire operational administrative module prompting dispatcher need remove ground wire at this moment; And and field verification, just can send the electricity operation.As shown in Figure 4, when removing the ground wire operation, ground wire operational administrative module is analyzed according to power network topology operational order (sending electric operational order) is resolved to operation order item by item, and carries out the electrical network simulated operation; In the simulated operating procedure through to electric network state before operating and the state comparative analysis of operation back: reach when removing the ground wire condition, at first need 252 closing of power circuit breaker be connected 252 circuit breaker both sides isolating switches then.After the EO processing safety is analyzed, intelligent decision goes out at 252 circuit breaker both sides hanging earthing conductors, ejects with the dialog box window form then, and the prompting dispatcher removes ground wire.
It is emphasized that; Embodiment of the present invention is illustrative; Rather than it is determinate; Therefore the present invention includes and be not limited to the embodiment described in the embodiment, every other execution modes that drawn by those skilled in the art's technical scheme according to the present invention belong to the scope that the present invention protects equally.
