Description

Technical Field

[0001] The present invention belongs to the field of substation design, and in particular relates to a substation virtual-real full-loop model information association method, system, equipment and medium. Background Art

[0002] In a smart substation, signals are connected to process-layer IED devices such as smart components through real-loop cables. Process-layer IED devices are connected to bay-layer IED devices such as protection, measurement and control through virtual terminals (virtual loops). Bay-layer IED devices then send the received signals to the station control layer network to reach the monitoring system.

[0003] Currently, in the traditional design process, the drawing design of the secondary real circuit and the virtual circuit design based on SCD (Substation Configuration Description) are carried out separately, and the real circuit information and the virtual circuit information cannot be unified. This results in the inability to associate the signal of the secondary real circuit with the virtual circuit signal in SCD, and the various updates of the signal definition of the real circuit cannot be automatically transmitted to other subsequent links. Therefore, on the one hand, it leads to an increase in manual workload and inconsistency of various signals before and after. For example, the independence of the virtual and real circuits makes it impossible to carry out real-time abnormality analysis, fault diagnosis and other technical applications. Daily operation and maintenance also requires manual comparison of virtual and real circuits, which brings inconvenience to operation and maintenance personnel.

[0004] Therefore, it is urgent to study a method for associating information between virtual and real full-circuit models of substations. The core of this method is to establish information association between virtual and real full-circuit models of secondary equipment based on SCD and real-circuit SPD models to achieve full-circuit connectivity. Summary of the invention

[0005] The purpose of the present invention is to provide a method, system, equipment and medium for associating information of virtual and real full-loop models of substations. By establishing information association of virtual and real full-loop models of secondary equipment, the full loop is connected, which can solve the problem that the existing substation loops, virtual loops and station control layer signals are relatively independent, the signals cannot be connected in the full loop, and real-time abnormality analysis, fault diagnosis and other technical applications cannot be jointly carried out.

When the component is a power input, power output or other signal output component, the search is interrupted, otherwise the search continues for the connected components; through this search, the loop topology of the substation is split into multiple small topology loops with the signal input component as the core;

[0017] In each small topological loop, all signal output elements are found, their series and parallel relationships are analyzed according to the connection relationship, and an association mapping between the signal input element and multiple signal output elements is established.

[0018] In particular, an association mapping is established between the secondary equipment in the process layer device and the process layer in the interval layer device via the process layer in the process layer device, including establishing an association relationship between the ICD model data object of the secondary equipment and its own signal acquisition element, mapping the physical terminal of the secondary equipment to the unique DO or DA node in the ICD model; and establishing a connection relationship between the virtual terminal of the process layer in the process layer device and the process layer logic device in the interval layer device; searching for all data receiving data objects through the virtual terminal connection, and then searching for all data sending data objects through the FCDA of the data set, merging the two parts of the data objects, thereby establishing an association mapping between the process layer in the process layer device and the process layer in the interval layer device.

[0048] The technical solutions and beneficial effects of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] The present invention provides a substation virtual-real full-loop model information association method, system, device and medium. First, by establishing the signal association and definition of the process layer and the interval layer device signal acquisition element, the signal mapping of the primary and secondary equipment physical loop is realized; then based on the mapping of the SPD model and the ICD model, the information association of the secondary equipment physical loop to the virtual loop is realized; then, by referencing the name and description retrieval and establishing a private mapping table, the process layer and the station control layer signal mapping is realized; finally, by mapping the virtual loop and the real loop port, the information association of the physical link and the virtual loop link is realized. Through the above steps, the present invention establishes a complete mapping relationship between the virtual loop, the real loop, and the station control layer signals, and finally forms the substation virtual-real full-loop model information association.

[0050] like Figure 1 As shown, a preferred embodiment of the present invention provides a method for associating information of a substation virtual-real full-loop model, comprising the following steps:

[0051] Step 1, establishing information association between the signal sending element and the signal collecting element of the access cable to realize signal transmission from the primary device to the secondary device;

[0052] The signal is generally transmitted from the terminal box of the primary device to the physical contact of the corresponding secondary device through the cable. To complete the mapping of primary and secondary device signals, it is necessary to retrieve the whole station logic model (SPD model), retrieve the component types on both sides of the cable, and obtain the complete relationship between the primary device signal definition and the secondary device according to the type of primary device output component and the type of secondary device signal acquisition component, so as to complete the signal transmission. It should be noted that some secondary devices are used for both receiving signals and sending signals. When used to receive signals, they serve as signal acquisition components; when used to send signals, they serve as signal sending components.

[0053] During the secondary circuit design process, the SPD model often only stores the component definitions of the output side equipment and the definitions of the inter-cabinet connections. In order to achieve full-circuit information transmission, it is first necessary to obtain the signal association and definition of the signal acquisition components of the process layer equipment. This mainly includes the following steps:

[0054] 1) Based on the SPD logic model, the signal transmission rules of the component are expanded. One of the connection points of the component type is selected as the signal definition point; define whether there is potential isolation between each connection point of the component and the potential type of each connection point. As shown in Table 1, the corresponding connection point potential transmission definition and the connection point number that maintains potential transmission are defined.

[0055] Table 1

[0056]

[0057]

[0058] 2) Analyze all the connections in the cabinet and between cabinets, and the connections in the components and between components (hereinafter collectively referred to as connections) in the SPD model, and divide the components into signal output and signal input components according to the component type; define the direct connection components such as terminals that do not input or output signals but transmit potential as direct connection components. Simplify the loop topology of the direct connection components and the connected components to form the loop topology between the signal input and output components. Figure 2 Simplified graphical connections are shown;

[0059] 3) Read all devices with IED type in the SPD model, obtain the list of all signal input components in the device and sub-devices, start from the signal definition point of the signal input component, search the loop topology, and find all components connected to the signal input component through the connection relationship. When the component is a power input, power output or other signal output component, the search is interrupted, otherwise the search continues. Through this search, the complete loop topology of the substation can be split into multiple small topology loops with the signal input component as the core;

[0060] 4) In each small topological loop in the previous step, find all signal output elements, analyze their series and parallel relationships according to the connection relationship, and establish an association mapping between the signal input element and multiple signal output elements;

[0061] Step 2, establishing the association between the real circuit and the virtual circuit of the secondary equipment in the process layer equipment (the process layer in the process layer equipment and the process layer in the bay layer equipment), and realizing the signal transmission from the real circuit to the virtual circuit and the bay layer;

[0062] For process layer IED devices such as intelligent components, the real loop is associated with the process layer signal of the ICD model through internal mapping, and then associated with the process layer logic device of the interval layer device through virtual terminal connection; for interval layer devices such as protection, measurement and control, the real loop is associated with the station control layer logic device of the ICD model through internal mapping.

[0063] To establish the above mapping relationship, it is first necessary to establish the association relationship between the physical circuit model and the virtual circuit model, that is, the association between the ICD model data object (DO) of the IED device and its own signal acquisition component. Its implementation mainly includes the association between the virtual and physical circuits based on SPD.

[0064] In the SPD model, the Device element describes the instantiated electrical device. The Device is composed of sub-devices, components, internal components, internal component connections, and connection points. Among them, the component represents a specific logical function on the electrical device, which is composed of one or more connection points on the device and includes the name, desc, group, type, and icdRef attributes. For the IED device, each logical function has a corresponding component, and its grouping is logic, including the icdRef attribute, with the format of "LD / LN.DO.DA". Therefore, by traversing the components grouped as logic in the IED device and using the icdRef attribute of the component, the physical wiring terminals of the secondary device can be mapped to the unique DO or DA (Data Attribute) node in the ICD model. The association relationship between the physical terminal and the ICD model signal is as follows Figure 3 shown. Its model example is as follows:

[0065] 1. <Devicename="1-13n" iedName="default" label="Merging Unit">

[0066] 2. <Partname="NR.ZD_PCS-221GB-G" num="1" / >

[0070] 6. <Componentname="I2" desc="Protective current phase B" icdRef="MUSV / TCTR2.Amp,MUSV / TCTR2.AmpChB" / >

[0078] 14.

[0079] For process layer IED devices such as intelligent terminals and merging units, the icdRef of their components should be associated with the data object (DO) under the process layer logical device (LD); for bay-level IED devices such as measuring and control units, it should be associated with the data object (DO) under the logical device (LD) of their substation control layer signals.

[0080] Then, for process layer IED devices such as intelligent terminals and merging units, it is also necessary to establish the association between the process layer devices and the process layer logical devices of the bay-level devices through virtual terminal connections.

[0081] In the implementation of current intelligent substations, process layer devices are connected to the process layer logical devices of bay-level devices through virtual terminal connections. Search for all received data objects DO through virtual terminal connections, and then search for all sent DO through the FCDA (entries) of the data set. The two parts can be combined to establish the association between the process layer devices and the process layer logical devices of the bay-level devices.

[0082] Step 3: Establish the information association between the process layer and the substation control layer to realize the signal transfer from the process layer to the substation control layer;

[0083] For the signals of the bay layer IED devices such as measurement and control that are directly connected by cable, the connection between the station control layer signal logic device of the primary device and the bay layer device has been established through steps 1 and 2; and for the signals of the process layer IED devices such as the intelligent terminal that are directly connected by cable, the connection between the process layer signal logic device of the primary device and the bay layer device has been established through the above steps, and the connection between the process layer logic device of the bay layer device itself and the station control layer logic device must be established before the signal can be sent to the station control layer device to complete the entire signal transmission.

[0084] The mapping association from the process layer to the station control layer in the smart substation is divided into the following cases:

[0085] a) In the ICD model of some IED devices, the process layer and the station control layer are under different logical devices (LD) but have the same reference name. In this case, the mapping association is established by searching whether there is a signal with the same reference in the station control layer.

[0086] b) If there is no DO with the same reference name, since the signals corresponding to the station control layer and process layer of the current power grid access detection device have the same and unique description, the mapping association is established through the DO with the same description attributes of the station control layer and the process layer.

[0087] c) If the above two methods cannot find the corresponding mapping association, the association between the process layer and the station control layer should be manually established through private attributes. Add a new attribute mapping table of the Private attribute of type NR_VARMAP in the IED element, and its value contains the short address (sAddr) of the station control layer and the process layer. By traversing all DAs of the station control layer and the process layer, searching for the DA with the same short address in the corresponding attribute mapping table, and obtaining its DO element, its mapping association can be established.

[0088] Step 4: The station control layer in the bay layer device sends a signal to the station control layer device through the communication network.

[0089] Furthermore, for the virtual circuit, an optical port mapping is also established between the process layers to realize the association between the virtual circuit signal and the physical optical fiber circuit;

[0090] The transmission of virtual circuits between process layers and interval layers is carried out through physical optical fibers. It is necessary to associate the physical connection corresponding to the optical cable in the SPD with the port mapping of the virtual circuit to achieve matching.

[0091] At present, in smart substations, the virtual terminal connection (ExtRef) of the receiving IED device in the SCD model is generally used to set the optical port number it receives. The optical port corresponding to the IED device in the SCD corresponds to the optical port component under the device with the same IEDName attribute in the SPD. Since the optical port name of the SCD is inconsistent with the name of the optical port component of the SPD, it is necessary to fill in the optical port name of the corresponding IED in the icdRef attribute of the optical port component of the SPD to establish its mapping.

[0092] Read the SCD model, parse the optical port of the data set subscribed by each IED device, and map it to the optical port component of the SPD model through the above steps. The corresponding connection point port (Port) can be found through the PinRef attribute of the optical port component type RX.

[0093] Analyze the fiber connection topology of the corresponding port, and treat the components in the loop with empty signal type and potential transmission as fiber switching, and track the fiber connections corresponding to other connection points of the components. Devices of type Switch are also regarded as data switching, and the topology diagram of the fiber components is established. Using the pre-order traversal method, search for the IEDName attribute of the device to which other optical port components connected to the component belong, and the fiber loop topology of the data set subscribed by the IED device can be established.

[0094] Another preferred embodiment of the present invention also provides a substation virtual-real full-loop model information association system, comprising:
