Description
Technical field
The present invention relates to electric power network technique fields, and in particular to one kind is for automatically generating distribution line definite value switch definite value figure
Synchronizing calculation method.
Background technique
Currently, the work of 10kV distribution network protection fixed value adjusting is there are the more heavy workloads of manpower intervention, calculating accuracy is low, calculates
Low efficiency, it is not intuitive the problems such as, relay protection constant value adjustment such as occurs, related personnel needs to return to office and re-start guarantor
Protect fixed value calculation, efficiency, in terms of can not all ensure completely.This project carries out distribution by carrying out in a deep going way to investigate
The solution party of complete intelligent protection definite value audio-visual picture is realized in intelligent protection fixed value calculation and setting management research work
Case reduces confusion caused by due to relay protection setting mistake.
The research of patent through the invention proposes a kind of for automatically generating the adjusting of distribution line definite value switch definite value figure
Calculation method protects fixed value calculation efficiency to improve, it is horizontal to promote power grid operation.
Summary of the invention
Being designed to provide for the embodiment of the present invention is a kind of for automatically generating the whole of distribution line definite value switch definite value figure
Determine calculation method, protection fixed value calculation efficiency can be improved, ensure the safe and stable operation of electric system.
To achieve the above object, the embodiment of the invention provides one kind for automatically generating distribution line definite value switch definite value
The synchronizing calculation method of figure can clearly understand the protection on current power distribution route by generating the audio-visual picture of protection definite value
Definite value detail, can facilitate related personnel to problem it is quick, facilitate investigation position；The method detected by crotch flashback is automatic
At figure step are as follows: first before automatic mapping, current power distribution route is segmented, by different level, classifying type accurately divided；
It is segmented partiting step: according to the difference of power supply mode on distribution line and the difference of the state of interconnection switch, to determine
The supply district of current line；
Partiting step by different level: according to topological connection relation, the belonging relation between equipment each on distribution line, the trunk of division
Trunk shaft tower belonging to route, branched line and branch；Each branch can according to the trunk shaft tower number belonging to branch to branch into
Row sequence；
Classifying type partiting step: the definite value situation of distribution line switch on intelligent definite value figure is obtained, according to the physical attribute of switch
It is divided into voltage-type switch and current mode switch；
It is the tree construction that paper space is divided into different levels that crotch flashback detection, which is drawn, and the space of known range is divided into
Several equal subspaces, what is stored in every sub-spaces is the markup information of each tree node and node；Individual subspace knot
Structure is fairly simple, and when spatial data object distribution is relatively uniform, with relatively high spatial data insertion and inquiry effect
Rate, therefore subspace object is stored on all tree nodes, tree node when storing deposit after mountable first trunk by the sequence of branch
Storage；
When drawing branch node, needs to carry out each branch to sort out to be sequentially distributed and be controlled in main line measurement progress rule, that is, exist
In branch when present node, main line coordinate where determining this branch is first needed, is then collided when drawing present node
It checks；Need to carry out the branch of flashback when collision Ergodic judgement can, calculated when object unit quantity is too many
Pressure is too big, needs to reduce the cost for finding the object that two may collide by a method；So being carried out to drawing empty
Between divide, as long as each node carry out to current location carry out collision detection, if check with the presence of node, this node
8 directions can be carried out around changing coordinates and carry out rotated detection collision, until checking successfully；
Therefore crotch flashback detection drafting method divides distribution line in combination with foregoing description, can be divided into when drawing route
The trunk of distribution line is drawn, branch draws.
Preferably, this method further include:
The length of the fixed connecting line drawn pixel shared by each switch, switch two sides；
It sets distribution line and draws direction, back gauge；
Start to draw all kinds of switches on the trunk of route, the sequence for switching drafting is arranged according to shaft tower number belonging to each switch
Sequence is drawn；
Trunk branch is ranked up according to affiliated trunk shaft tower number；
It carries out drawing each branched line, every branch switch progress for drawing a branch switch and all needing and having drawn by shaft tower flashback
Collision detection.
The present invention also proposes a kind of computer equipment, including memory, processor and storage on a memory and can located
The computer program that runs on reason device, the processor are realized above-mentioned for automatically generating distribution line when executing described program
The synchronizing calculation method of definite value switch definite value figure.
