All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in FIG. 1, the invention provides a power distribution network medium voltage fault comprehensive analysis and information prompt system, an actual power distribution network is simulated into a GIS drawing unit, a fault identification unit which is the same as the actual power distribution network is provided in the GIS drawing unit, the fault detection node information collected in real time is used for triggering the fault identification unit in the GIS drawing unit to work, the fault position is marked timely and quickly, and the influence range of the fault position on the power distribution network is displayed in the GIS drawing unit, so that the protection and the defense of lines in the influence range are facilitated in advance, the fault position is conveniently found out timely, a solution is formulated, effective fault research and judgment of distribution network emergency repair commanders is facilitated, and medium voltage fault events are handled timely.
The comprehensive fault analysis system specifically comprises a power distribution network module dividing unit 1, a power distribution network GIS drawing unit 2, a fault information counting unit 3, a detection information processing unit 4 and a fault planning and solving unit 5.
The fault information statistical unit 3 constructs coordinate systems of different units according to the classification of the detection data, integrates the detection data of each fault detection node in the coordinate systems according to the classification, and generates a real-time dynamic graph of the fault detection data.
The detection information processing unit 4 sets a detection object threshold value of each detection node, compares the collected fault detection node data with the threshold value in real time, and judges the fault occurrence position in time;
the fault planning solution unit 5 calculates the fault upstream and downstream information according to the fault occurrence position, calculates the power loss load, and analyzes the power conversion and restoration scheme.
The power distribution network module dividing unit 1 is used for setting a plurality of fault detection nodes on a power distribution network and dividing the power distribution network into detection modules with control relations.
The data detected by the fault detection node specifically includes information of current, voltage, power, temperature and the like, and any information affecting the operation of the power distribution network can be used as the detection information of the fault detection node.
In the embodiment, the fault detection node divides the whole power distribution network into different detection modules and assists in determining the network topology control relationship in the power distribution network, so that the arrangement and selection of the fault detection node are important.
The specific steps for laying the fault detection nodes are as follows:
adding a primary fault detection unit on a plurality of branch lines of the primary distribution transformer equipment, and naming each fault detection node in the range of the primary fault detection unit in a way of specifically setting I1, I2, I3, … … and Ii (I is the number of the branch lines of the primary distribution transformer equipment).
Generally speaking, the first-level fault detection unit can control the line on-off relation of the corresponding second-level fault detection unit, that is, the lower-level distribution transformer equipment is controlled by the upper-level distribution transformer equipment, when the upper-level distribution transformer equipment has a fault problem, the lower-level distribution transformer equipment is also affected by the fault problem, and the first-level fault detection unit in the equipment is concerned with the total on-off condition in the graded distribution transformer equipment.
Adding secondary fault detection units on a plurality of branch lines of secondary distribution transformer equipment, naming each fault detection node in the range of the primary fault detection unit, wherein the naming mode is specifically set to be Ii-IIm; … … (i is the number of branch lines of the first-stage distribution transformer equipment, m is the number of branch lines of the second-stage distribution transformer equipment).
When the distribution transformer equipment below the second level is particularly applied to a region, the naming mode is analogized to know that the distribution transformer equipment is mainly influenced by the fault in the higher-level distribution transformer equipment or the fault in the lower-level distribution transformer equipment, so that the higher-level distribution transformer equipment and the lower-level distribution transformer equipment which are possibly influenced by the fault can be quickly found through the naming mode of the fault detection node.
For example, when the whole distribution network has three levels of distribution transformer equipment, and one fault detection node is named as I4-II3-III8, once a specific fault problem occurs in the II3 node, problems can occur in reverse pushing I4 and III8, and other network topology circuits connected with I4 and III8 can also be affected.
N-level fault detection units are added on a plurality of branch lines of n-level distribution transformer equipment, and each fault detection node in the range of the n-level fault detection units is named in a specific mode of Ii-IIm-IIIp- … … -Nr (i is the number of branch lines of the first-level distribution transformer equipment, m is the number of branch lines of the second-level distribution transformer equipment, p is the number of branch lines of the third-level distribution transformer equipment, … … and r is the number of branch lines of the n-level distribution transformer equipment).
Similarly, by the naming mode, the line range influenced by the fault point can be quickly found, and a power conversion and restoration scheme can be conveniently and timely formulated.
A plurality of detection points which are uniformly distributed are arranged between two distribution transformer devices, an interval fault detection unit is added to each detection point, and each fault detection node in the range of the interval fault detection unit is named.
That is to say, the naming mode of the fault detection node between the primary distribution transformer equipment and the secondary distribution transformer equipment is generally according to the number of branch lines of each level of distribution transformer equipment, and the fault detection node on each branch line of the primary distribution transformer equipment is named as I1-a, I1-b, I1-c and … …; i2-a, I2-b, I2-c, … …; i3-a, I3-b, I3-c and … ….
The fault detection nodes on each branch line of the secondary distribution transformer equipment are named as II1-a, II1-b, II1-c and … …; II2-a, II2-b, II2-c, … …; II3-a, II3-b, II3-c, … ….
By analogy, when a problem occurs in the power transmission process of each stage of distribution transformer equipment, a plurality of fault detection points are arranged between two stages of distribution transformer equipment, so that the fault detection nodes of the corresponding branch line power transmission sections can be directly and quickly searched, the number of sections of the troubleshooting line can be reduced, and the fault solving efficiency is improved.
The distribution network GIS drawing unit 1 is also used for simulating the distribution condition of a transmission circuit of the distribution network by using a GIS system, a fault identification unit is correspondingly added on each fault detection node, and the distribution network GIS drawing unit generates a simulated distribution network according to the actual distribution data of the transmission circuit of the distribution network.
The step of generating the GIS map about the power distribution network by the power distribution network GIS drawing unit specifically comprises the following steps:
firstly, the distribution transformer equipment in the GIS platform is loaded and a mesh connection relation graph is formed.
In this step, a general mesh connection relation diagram of the distribution transformer equipment is preliminarily formed, and the mesh connection relation diagram only represents the distribution condition of the distribution network.
Then, the tree traversal algorithm is used for searching the associated control lines in the mesh connection relation graph, and a fault identification unit is arranged at each traversal node position.
The traversal algorithm used in the embodiment is specifically breadth-first traversal, and the breadth-first traversal is characterized in that the nodes on a certain layer are searched in a layer sequence and then are searched for the next layer, that is, the nodes are accessed from a first-stage distribution transformer device, all branch lines of the first-stage distribution transformer device are accessed and then sequentially accessed to a next-stage distribution transformer device, and through the access of the layers, the associated control lines in the distribution transformer device can be conveniently searched, and the corresponding control relationship can be quickly found.
In addition, each traversal node in the associated control line represents one fault detection point in each stage of distribution transformer equipment and also represents a plurality of detection points arranged between two distribution transformer equipment, and meanwhile, because the associated control line in the mesh connection relation graph is obtained by using a breadth-first traversal algorithm, when one detection point has a fault, the influence range of the fault can be calculated by using the associated control line, the fault can be comprehensively analyzed more intuitively and simply, and meanwhile, the user can be helped to quickly obtain fault information by using the self function of the associated control line.
The fault identification unit in the embodiment has the function of responding to the fault occurrence time in time, when the data of the fault detection node is abnormal, the fault data of the fault detection node controls the fault identification unit to work, the fault identification unit displays the fault occurrence time in real time, namely, the fault identification unit in the distribution network GIS drawing unit works fast in time, and a first site where the fault occurs can be marked in time, so that the fault line troubleshooting time is shortened, and the fault maintenance efficiency is improved.
The fault identification of the fault identification unit mainly depends on the color change of the fault detection node after the fault is responded, specifically, the inverse proportional function relationship between the fault occurrence time and the RGB is adopted, when the fault occurrence time is longer, the RGB of the fault identification color is smaller, the fault identification color is darker and darker, that is, the RGB of the fault identification color is reversely reduced along with the fault occurrence time, the unit of the fault occurrence time is s, the fault occurrence time is prolonged by one second, and the RGB values are respectively reduced by an equivalent value.
Specifically, for example, the standard values for RGB without fail response are R255, G255, and B0.
When the trouble takes place, trouble identification element in time marks out the trouble position, and from RGB's standard value, R and G diminish simultaneously, and that colour will be darker and darker, and R, G, B all become black for 0 at last.
In summary, the principle of using the fault identification unit to prompt the occurrence sequence of the faults in the present embodiment is as follows:
when a fault occurs, the detection information processing unit sends fault information to the fault identification unit in time, the fault identification unit responds, the color begins to appear on a traversal node on the GIS drawing, at the moment, R is 255, G is 255, and B is 0;
as the fault triggering time continues, R and G become smaller at the same time, and the color of the first fault occurrence point becomes darker and darker;
the first fault occurrence point affects other branch lines in the power distribution network, so that fault identification units on other traversal nodes also start to respond to faults, the corresponding traversal nodes start to appear colors, at this time, R is 255, G is 255, and B is 0;
as the fault triggering time continues, R and G become smaller at the same time, and the color of the fault occurrence point becomes darker and darker;
due to the fact that time difference exists between the first fault occurrence point and the fault occurrence point caused by secondary influence, the color of the fault identification unit of each traversal node is judged to be dark and light, the first fault occurrence position can be found quickly, and timely maintenance is facilitated.
In addition, the fault identification unit is used for marking the information of the fault, the data of the fault detection node is not collected any more, as long as the fault identification unit triggers work, RGB data are correspondingly changed through the change of every second, and therefore the accuracy of judging the first fault position can be improved, obviously, the fault information statistical unit (3) cannot collect data once every second, and therefore the first fault position cannot be immediately judged only through the fault information statistical unit (3).
Then, the line control nodes in the associated control lines are counted, and a line control node list of the power distribution network lines is generated.
GIS drawings help users to visually check fault occurrence positions and fault influence associated lines, in order to further help users to determine maintenance schemes and analyze power-switching and power-restoration lines, line control nodes of power distribution lines need to be generated into detailed tables, control nodes needing power-off maintenance can be visually judged according to the naming mode of fault detection points, normal power supply is facilitated by switching power from other line control nodes, and meanwhile subsequent power-restoration operation is facilitated for each node.
And when the fault identification unit is triggered, automatically searching the line control node list, and calculating the information of the fault upstream and the fault downstream by the fault planning solution unit according to the line control node list and the fault occurrence position, and analyzing a power conversion and restoration scheme.
And finally, displaying the distribution lines formed by connecting the line control nodes according to the network topology.
That is, when a fault occurs, distribution lines which may be affected are defined according to line control nodes, thereby facilitating emergency fault prevention.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention.
