Description
Technical field
The present invention relates to the shaft tower information modelling approach of technical field of electric power, more particularly to a kind of transmission line of electricity.
Background technology
First：The transmission line of electricity number of power network is not known, and is occurred in evolution newly-increased or removal transmission line of electricity
Situation.Simultaneously for a transmission line of electricity, the number of its shaft tower is not known, and is related to increase during later maintenance and is removed bar
Tower, the representation of the fixed columns of tradition does not adapt to such business；Second：Be actually to the local maintenance of circuit using shaft tower as
Foundation, every section of circuit safeguarded by the shaft tower affiliated unit where it, therefore for long-distance transmission line, during failure
One time determined that its accountability unit was most important；3rd：Electric power system dispatching separates two pieces of business from system, and one is regulation and control
Management, is responsible for the fault location of transmission line of electricity, only recognizes trouble point to the distance number of transformer station.One is transmission of electricity repairing, before being responsible for
Fixed a breakdown toward the position of fault, the shaft tower numbering only recognized near trouble point.Therefore, for transmission of electricity repair personnel, it is not known that
Regulate and control the corresponding shaft tower numbering of the distance number provided, for regulation and control personnel, it is not known that the actual inspection of transmission of electricity repair personnel is true
The shaft tower recognized is corresponding apart from number.4th, it is necessary to notify at multiple departments after transmission line of electricity or shaft tower information are changed
Reason, often takes time and effort, there is also various omissions, cause the data between all departments inconsistent.The a variety of deficiencies of the above, to across special
Industry high-level scheduling commander buried hidden danger, be this we have proposed a kind of shaft tower information modelling approach of transmission line of electricity.
The content of the invention
The present invention proposes a kind of shaft tower information modelling approach of transmission line of electricity, to solve what is proposed in above-mentioned background technology
Problem.
The present invention proposes a kind of shaft tower information modelling approach of transmission line of electricity, comprises the following steps：
S1, power system transmission line are formed by a series of support of shaft towers is built on stilts, are connected between transmission line of electricity by transformer station
Connect；
S2, after modeling, transmission line of electricity corresponds to circuit, and the two ends of circuit are referred to as end points, the intersection of a plurality of circuit
Multiple end points, one transformer station of ordinary circumstance lower node correspondence are included on referred to as node, each node；
Multiple shaft towers on S3, transmission line of electricity, are divided on one group of associated line segment, model and are denoted as line
Road is divided into multiple sub-pieces, every shaft tower one sub- point of correspondence, the circuit corresponding one between shaft tower and shaft tower by one group of son point
Individual line segment, sub- point possesses affiliated unit, geographical longitude and latitude, the attribute of shaft tower numbering, and sub-piece, which possesses, uses span attribute, simultaneously
Also affiliated previous height point and the attribute of latter height point；
S4, numbered by the previous height point belonging to sub-piece and latter height point, sub- point can be carried out to orderly combination,
Form sub-piece sequence；
S5, the shaft tower number put by sub-piece sequence, acquisition and sub-piece use span attribute, energy reduction go out specific
The corresponding physical distance of numbering shaft tower, conversely, can also extrapolate the shaft tower of reference numeral by given distance value, and then is determined
The O＆M unit of the shaft tower, advantage is：For the regulation and control personnel for being only concerned distance, a distance value is provided with regard to finger can be assigned
Order, commander's O＆M unit goes to the place operation, and track walker need to only report the numbering of failure shaft tower, and regulation and control personnel can just obtain
The distance of accident spot is known, so as to take emergency measures；
When S6, regulation and control personnel send the distance instruction of accident spot, changed by the model value of computer, each O＆M list
What position was obtained is understandable shaft tower numbering, and whether conveniently judge the shaft tower is oneself compass of competency, and then decides whether to arrange people
Member goes to processing；
S7, further, shaft tower physically can correspond to the sub- point on multiple models, defeated in actual demand to meet
The case model that electric line parallel lines on same tower, T connect represents that parallel lines on same tower is equivalent to the same shaft tower of son point correspondence of different circuits, T
The process connect, two are split into equivalent to original circuit, two new end points occur, with node the two new end points
With need the end points of circuit that T taps into be associated；
S8, when needing to increase shaft tower newly in the centre of existing line, will equivalent to inserting new sub- point on circuit model
Original sub-piece is divided into two sub-pieces, the corresponding sub-piece of synchronized update, sub- point respective attributes；
S9, similarly, when circuit needs to delete shaft tower, equivalent to first deleting the corresponding sub- point of shaft tower on circuit model,
The sub-piece that this sub- point is associated again is merged；
S10, when adjacent two lines road is merged, equivalent to by all sub- points belonging on wherein one circuit model all
Another circuit model is directed to, then deletes the line information.
It is preferred that, in above-mentioned, the step of additions and deletions of shaft tower information, query statement are performed, by original single modeling of tradition
Exponential operation, be reduced to Constant Grade operation.
It is preferred that, in above-mentioned, transmission line of electricity carries out unified Modeling by shaft tower information, it is adaptable to computer representation,
Distance and shaft tower numbering, easily switch between the business of O＆M unit, eliminate power system regulation and administration and transmission of electricity repair personnel it
Between major differences.
It is preferred that, in above-mentioned, by transmission line of electricity, shaft tower, the information-based modeling of the unified progress of substation information, distribution is unique
Numbering, is easy to dispatch, protects, the data exchange of each information system of observing and controlling, is easy to later stage each information subsystem integrated.
A kind of beneficial effect of the shaft tower information modelling approach of transmission line of electricity proposed by the invention：In informationization modeling
In, each shaft tower of every circuit, which has, oneself is uniquely numbered, and this shaft tower information can be carried out to information-based modeling, and this process is complete
It can be completed entirely by computer,, can be by the form of database in face of magnanimity information so as to greatly improve the precision of tower spotting
Real-time query is carried out, while it is easy to the processing of additions and deletions, modeling method proposed by the present invention, by before original recall precision is ensured
