Description

Technical Field

[0001] The present invention relates to the technical field of distribution network visualization, and in particular to a method and system for generating an electrical wiring diagram of a distribution room based on four quadrants. Background Art

[0002] A distribution room refers to an indoor distribution site with low-voltage loads. It mainly distributes electricity to low-voltage users and is equipped with medium-voltage incoming lines (a small number of outgoing lines may be provided), distribution transformers, and low-voltage distribution devices. Facilities for load equipment at voltage levels of 10kV and below are divided into high-voltage distribution rooms and low-voltage distribution rooms. High-voltage distribution rooms generally refer to 6kV-10kV high-voltage switch rooms; low-voltage distribution rooms generally refer to 400V distribution rooms with 10kV or 35kV station transformer outgoing lines.

[0003] As the scale of distribution network construction gradually expands, the load equipment gradually increases. In order to achieve observable and controllable distribution network, real-time online monitoring and control of lines, distribution stations, distribution rooms, etc. in the distribution network based on the distribution automation master station system has become the basis for the construction of intelligent distribution network.

[0004] As an important technology for realizing the intelligentization of power grid, graphic technology has been widely used in the fields of power generation, transmission and distribution of power system. Common power graphics include plant main connection diagram, transmission network geographical connection diagram based on geographic information, transmission network flow diagram on the dispatching large screen, transmission and distribution network system diagram and single-line diagram, etc.

[0005] In order to realize information monitoring inside the distribution room, drawing the electrical wiring diagram inside the distribution room is the basis. The relevant wiring diagram can be drawn on the current CAD system, PMS system, DMS system and marketing procurement system.

In addition, the continuous commissioning of new substations, the increase of lines, and the complexity of the power grid structure have made the above problems increasingly prominent. As a result, the traditional power graphics drawing method has the disadvantages of low work efficiency and easy errors. Summary of the invention

[0036] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For easier understanding, see Figure 1 The present invention provides a method for generating a four-quadrant distribution room electrical wiring diagram, comprising the following steps:

[0038] S1. Based on the blank screen environment as the wiring diagram background, a rectangular coordinate system is established with the center of the screen as the origin to obtain the first quadrant area, the second quadrant area, the third quadrant area and the fourth quadrant area.

[0039] S2. Add all the busbars in the distribution room to the first quadrant, the second quadrant, the third quadrant and the fourth quadrant in sequence according to the four preset voltage levels from high to low, so as to obtain the busbars and their quadrants corresponding to each voltage level.

[0040] It should be noted that, in general examples, the voltage levels in the power system are 380V, 10kV, 35Kv, and 110Kv. According to the order of voltage levels from high to low, the busbar with the highest voltage level is placed in quadrant A, the busbar with the second voltage level is placed in quadrant B, the busbar with the third voltage level is placed in quadrant C, and the busbar with the fourth voltage level is placed in quadrant D. Figure 2 As shown, the short lines are the busbars of each zone, point O is the center point of the screen, O′ is the origin coordinate of the busbars of zones A and C, and O″ is the origin coordinate of the busbars of zones B and D.

[0041] S3. Based on the pre-established power grid CIM model, the topological connection relationship between all busbars and all load devices, all switches, and all transformers in the distribution room is obtained.

[0042] It can be understood that the power grid CIM model, also known as the power grid public information model, is an abstract model that describes all the main objects of the power enterprise and represents the power system resources with object classes and attributes and the relationship between them. Due to the large scale of the complete CIM, the object classes contained in the CIM are divided into several logical packages, each of which represents a part of the entire power system model. The CIM specification uses the Unified Modeling Language (UML) expression method, which defines the CIM as a set of packages. Each CIM contains one or more class diagrams, which graphically display all the classes in the package and their relationships. Then, according to the attributes of the class and the relationship with other classes, each class is defined in text form. For example, the content of IEC61970-301 includes core packages, domain packages, power generation packages, power generation dynamic packages, load model packages, measurement packages, outage packages, production packages, protection packages, topology packages and wire packages. The class diagram of each CIM package shows all the classes in the package and their relationships.

[0043] S4. Connect each busbar, each load device, each switch and each transformer based on the topological connection relationship to generate an electrical wiring diagram for the distribution room.

[0044] It should be noted that, in this embodiment, by constructing the first quadrant, the second quadrant, the third quadrant and the fourth quadrant in a blank screen environment, all the busbars in the distribution room are added to the first quadrant, the second quadrant, the third quadrant and the fourth quadrant in sequence according to the preset four voltage levels from high to low, and then the topological connection relationship between all the busbars and all the load devices, all the switches and all the transformers in the distribution room is obtained through the power grid CIM model, and each busbar, each load device, each switch and each transformer are connected according to their topological connection relationship to generate an electrical wiring diagram of the distribution room, thereby improving the work efficiency of drawing the wiring diagram and reducing the error rate.

[0045] In one embodiment, step S3 specifically includes:

[0046] S301. Construct a voltage level structure matrix, a busbar structure matrix, a transformer structure matrix and a switch structure matrix based on a pre-established power grid CIM model; wherein the voltage level structure matrix is ​​used to record the buses of various voltage levels contained in the power distribution room; the busbar structure matrix is ​​used to record the busbars contained in the power distribution room and the load equipment information connected to the busbars; the transformer structure matrix is ​​used to record the transformers contained in the power distribution room and the switch information connected to them; the switch structure matrix is ​​used to record the switches contained in the power distribution room and the load equipment information connected to the switches;

[0047] S302. Determine the topological connection relationship between each load device, each transformer, each switch and busbar in the distribution room according to the voltage level structure matrix, the busbar structure matrix, the transformer structure matrix and the switch structure matrix.

[0048] Specifically, the voltage level structure matrix can be described as:

[0051] Among them, the LINK vector is determined according to the connection topology between devices, that is, according to the static model of the distribution network area.

[0052] The busbar structure matrix can be described as:

[0053] B=[BUSBAR,TRANS,SWTRAN,SWEQU,LINKTYPE,VERBUS,BPOS,LENGTH]

[0055] There are three types of bus connection, namely, value 1 means that the bus is only connected to non-transformer equipment; value 2 means that the bus is connected to a two-winding transformer in addition to non-transformer equipment, or the bus is only connected to a two-winding transformer; value 3 means that the bus is also connected to a three-winding transformer in addition to non-transformer equipment, or the bus is only connected to a three-winding transformer.

[0056] The location of the busbars is from the origin of each zone to the edge of each zone, and is arranged in order from large to small according to the connection type of the busbars.

[0057] The length of the bus is determined by the equipment connected to the bus and the bus corresponding to its vertical zone; the starting position coordinates of the bus are determined by the starting coordinates of the upstream bus in its area and the length and interval width of the upstream bus.

[0058] The transformer structure matrix can be described as:

[0059] T=[TRANS,LINKBUS,LINKSW,TPOS,GRAUNIT]

[0061] Among them, all IDs in this embodiment are unique and are determined according to the CIM model of the distribution network, that is, the device IDs derived from other systems, and can be any form of unique representation, which can be a number or a string, etc.

[0062] The location coordinates of the transformer are determined by the location coordinates of the upstream transformer in the area where it is located, the width of the transformer element and its interval width.

[0063] The switch structure matrix can be described as:

[0064] S=[SW,T0LINK,T1LINK,TYPE,GRAUNIT]

[0065] The switch structure matrix is ​​a 5×s matrix, in which the first row of SW vectors represents the switch ID, the second row of T0LINK vectors represents the load device ID connected to the first end of each switch, the third row of T1LINK vectors represents the load device ID connected to the second end of each switch, the fourth row of TYPE vectors represents the type of load device connected to each switch, and the fifth row of GRAUNIT vectors represents the drawing primitives of each switch.

[0066] There are two types of switch connection types, namely, a value of 1 indicates that the switch connects the busbar to a non-transformer device; a value of 2 indicates that the switch connects the busbar to a transformer.

[0067] The following is an example of the present invention:

[0068] Table 1 shows the equipment information of a power distribution room, which includes 2 voltage levels, one 10kV and one 0.4kV; 4 busbars, busbar 1 to busbar 4; 10 switches, switch 901 to switch 904, switch 201 to switch 206; 4 lines, high-voltage incoming line 1, high-voltage incoming line 2, low-voltage outgoing line 1, low-voltage outgoing line 2; and 1 energy storage, battery 1.
