[0024] Example 1:

[0025] Figure 1 This is a flowchart illustrating a new generation of high-reliability substation configuration-free parameter design method provided in Embodiment 1 of the present invention. This method is applicable to automatically generating configuration-free parameters in a new generation of high-reliability substations. This method can be executed by a new generation of high-reliability substation configuration-free parameter system, wherein the device can be implemented by software and / or hardware, and is generally integrated on an electronic device. In this embodiment, the electronic device includes, but is not limited to, devices such as computers.

[0026] like Figure 1 As shown in Embodiment 1 of the present invention, a new generation of high-reliability substation parameter-free design method includes the following steps:

[0027] S110. Construct a primary wiring diagram, which includes the topology relationships in the smart substation.

[0028] The primary wiring diagram is a standardized schematic diagram in a power system used to show the connection relationships of electrical equipment (such as circuit breakers, disconnectors, transformers, busbars, etc.) in the primary circuit. Topology can refer to the physical structure and logical connection relationships formed by the electrical connections of primary electrical equipment (such as circuit breakers, disconnectors, transformers, busbars, etc.).

[0029] In this embodiment, a main wiring diagram can be constructed first, which may include the topological relationships in the smart substation.

[0030] In one embodiment, constructing a primary wiring diagram includes: designing a topology based on primary equipment; defining primary bay attributes for primary bays in the topology, wherein the primary bay attributes include at least the bay number of the primary bay; determining the scheduling name of the primary equipment and mapping and associating the scheduling name with the bay number of the primary bay corresponding to the primary equipment; and determining the number of windings and polarity of all current transformers (CTs) in the topology, as well as the number of windings and secondary ratings of all voltage transformers (PTs).

[0031] Primary equipment refers to electrical equipment that directly participates in the production, transmission, distribution, and use of electrical energy in a power system. Its function is to realize the conversion, transmission, and control of electrical energy, directly bearing the voltage, current, and power of the power system under normal or fault conditions. A primary bay can be an independent functional unit in a power system composed of primary electrical equipment (such as circuit breakers, disconnectors, instrument transformers, lines, or transformers). It can be used to complete specific tasks of electrical energy transmission, distribution, or transformation, and usually corresponds to a specific power circuit (such as a line bay, transformer bay, or busbar equipment bay). Primary bay attributes refer to specific attribute values ​​describing the characteristics, functions, and operating parameters of a primary bay, used to clarify the electrical characteristics, equipment configuration, and operating logic of the bay. Bay number can be a unique identifier for a primary bay. Dispatch naming can be a unique name and number assigned to primary electrical equipment, used to clarify the equipment's identity, function, and topological relationship within the system. The winding of a current transformer (CT) refers to the coil wound with insulated wire inside the current transformer, and the polarity of the CT refers to the relative direction of the current between the primary and secondary windings during electromagnetic induction. The winding of a voltage transformer (PT) can refer to the coil inside the voltage transformer used to achieve electromagnetic induction conversion from high voltage on the primary side to low voltage on the secondary side. The secondary rating can refer to the standard voltage value and capacity of the PT secondary winding during normal operation.

[0032] In this embodiment, the primary equipment can be used to design the topology relationship and define the primary interval attribute of the primary interval in the topology relationship. The scheduling name of the primary equipment is mapped and associated with the interval number of the primary interval corresponding to the primary equipment. The number of windings and polarity of all current transformers (CTs) in the topology relationship, as well as the number of windings and secondary rating of all voltage transformers (PTs) are determined, thereby completing the construction of the primary main wiring diagram.

[0033] For example, Figure 2 A schematic diagram of a primary main wiring diagram provided in an embodiment of the present invention, such as... Figure 2As shown, the design of a primary topology can include necessary primary equipment such as buses, transformers, lines, circuit breakers, and instrument transformers. Defined primary bay attributes can include voltage level, wiring type, bay type, and bay number. Primary bay attributes can be used for IED name generation and can also adapt to different types of configuration-free parameter templates, providing a basis for configuration-free parameter generation. Information such as the scheduling name (project name) of primary equipment can also be defined, and a mapping association can be established between the primary equipment scheduling name (project name) and the primary equipment bay number. Scheduling name is mainly used for IED naming and the description of the instantiated IED when adding an IED. The number and polarity of CT windings are defined; this parameter is mainly used for whether the current is connected with positive or reverse polarity when configuring a virtual loop. The number and secondary rating of PT windings are defined; this parameter is mainly used for selecting the cascaded voltage when configuring a virtual loop—whether to cascade A-phase voltage or three-phase voltage.

[0034] S120. The topology diagram is formalized into a structure that adapts to the description of configuration-free parameters, including the introduction of adapted secondary device groups and the pre-setting of different types of default parameter values.

[0035] In this embodiment, secondary equipment groups are added and associated with the corresponding bays in the main wiring diagram, either automatically or manually. For example, the manual addition method can be as follows: when adding an IED within a bay, set the IED's bay number, equipment type, set type, voltage level, bay type, and branch phase number. The automatic addition method can be as follows: configure the secondary equipment groups to the maximum extent possible according to the voltage level and bay type of each bay. For example, in a 500kV circuit breaker bay, automatically configure 2 sets of circuit breaker protection, 2 sets of circuit breaker acquisition and execution units, and 1 set of circuit breaker measurement and control.

[0036] In one embodiment, associating the Intelligent Electronic Devices (IEDs) in the substation configuration description SCD file with the corresponding bays in the main wiring diagram includes: obtaining each primary bay in the main wiring diagram; for each primary bay, configuring a secondary equipment group with the goal of maximizing the voltage level and bay type of the primary bay, the secondary equipment group including one or more IEDs, the parameters of the IEDs including bay number, equipment type, set, voltage level, bay type and branch phase number; and associating the secondary equipment group with the primary bay.

[0037] The voltage level refers to the rated voltage at which the IED is designed to operate. The IED type can include incoming line IEDs, outgoing line IEDs, bus tie IEDs, transformer IEDs, capacitor / reactor IEDs, and PT IEDs. The secondary equipment group refers to an organic combination of various devices that monitor, control, protect, regulate, and communicate the operating status of the primary system. Indirect control of the power system is achieved through signal acquisition, processing, and command transmission from the primary equipment. The IED number is a unique identifier for the primary electrical IED to which it belongs. The equipment type can be a category based on the IED's function. The protection set can be for dual or triple protection configurations, identifying the number of protection sets to which the IED belongs, used to distinguish equipment groups in redundant systems. The IED voltage level can be the rated voltage level of the primary system served by the IED. The IED IED IED type can be the functional attribute of the primary IED to which it belongs. The branch phase number can be the number identifying the phase (A / B / C phases) or branch circuit associated with the IED. For example, the branch phase number can refer to the branch number (branch one, branch two) on the low-voltage side of the transformer, the phase number (phase A, phase B, phase C) of the transformer body acquisition and execution unit, and the phase number of the high-resistance body acquisition and execution unit.

[0038] In this embodiment, for a primary bay in the main wiring diagram, the goal is to maximize the voltage level and bay type of the primary bay. Secondary equipment groups can be configured, and then the secondary equipment groups can be associated with the primary bay, so that a single primary bay or the entire substation can support more types of bays.

[0039] In this embodiment, after adding all IED devices to the substation, the IED name and description can be automatically generated. The IED name can be generated using a 6-layer structure, consisting of device type, bay type, voltage level, bay type, bay number, and branch phase number. The IED description is generated in the order of voltage level, bay type, and device type. For example, in a 500kV circuit breaker bay, one IED device is added. The bay number is 1, the voltage level is 500kV, the device type is protection, the bay type is circuit breaker, and the type is the first set; the branch phase number is none, and the dispatch name is 5011 circuit breaker. Then the IED name is P_B5001A, and the IED description is the first protection set for the 500kV 5011 circuit breaker.

[0040] Based on the basic structure of IED: equipment type, bay type, voltage level, bay type, bay number, and branch phase number, an adaptation type identification system is constructed, the corresponding implementation configuration-free parameter template is extracted, and default parameter values ​​are preset.

[0041] S130, IED configuration-free parameters are generated based on the three-level strategy assignment.

[0042] The IED configuration parameters may include common parameters, virtual terminal connection parameters, extended adaptability parameters, and safety automatic configuration parameters.

[0043] In this embodiment, topological relationships and configuration-free parameters of all IED devices at the site can be used.

[0044] In one embodiment, the IED configuration parameters include one or more of the following: common parameters, virtual terminal connection parameters, extended adaptability parameters, and safety automatic configuration parameters; wherein, the common parameters include the IED bay number, voltage level, wiring method, set type, and virtual local area network (VLAN) tag; the virtual terminal connection parameters include connecting bus groups, connecting circuit breaker bays, protection configuration methods, and branch or tributary connection relationships; the safety automatic configuration parameters include connecting safety automatic device objects, tripping and closing tributary numbers.

[0045] In this embodiment, common parameters refer to parameters of common attributes of the IED, which may include the IED's bay number, voltage level, wiring method, set, and Virtual Local Area Network (VLAN) tag. Virtual terminal connection parameters may include connection to bus groups, connection to circuit breaker bays, protection configuration methods, and branch or tributary connection relationships; these parameters can be used to describe connection relationships with other IED devices. Expanded adaptability parameters can be used to describe parameters of bay protection devices or new independent protection or safety automatic devices whose connection objects are common datasets; adaptability is improved by changing the sending dataset of the subscribed object. Safety automatic configuration parameters may include the connected safety automatic device object, tripping and closing tributary numbers; these parameters can be used to describe the connection relationships between various configuration-free secondary devices and safety automatic devices.

[0046] This embodiment defines and classifies various parameters of primary equipment and IED equipment in detail, such as primary interval attributes, CT / PT winding parameters, and common parameters of IED equipment, so that the equipment parameter configuration is systematic, reducing ambiguity and arbitrariness, and further improving the standardization of configuration.

[0047] For example, Figure 3 A schematic diagram of a three-way wiring provided in an embodiment of the present invention is shown below. Figure 3 As shown, taking the side circuit breaker bay closest to busbar 1 as the center, the topological relationship between this side circuit breaker bay and the adjacent line bay, main transformer bay, and circuit breaker bay is as follows: busbar group 1 is named bus I, busbar group 2 is named bus II, the circuit breaker bay closest to bus II is the side circuit breaker bay, and the line or main transformer bay closest to bus II is the side bay.

[0048] Based on the topology, IED configuration parameters are generated, taking P_B5001A as an example:

[0049] For configuring common parameters, the following generation strategies can be used: Local Interval Number: This can be the interval number of the current interval. Set Type: This can be the set type of the current device, set when adding an IED device. Wiring Type: This can be the wiring type of the current interval, specifically based on the primary topology analysis. Voltage Level: This can be the voltage level parameter of the current interval, set in the main wiring diagram. VLAN Tag: This can be the VLAN tag of the current device.

[0050] The connection of circuit breaker bays can be configured through a primary topology. For example, the generation strategy for connecting the edge 1 circuit breaker bay is as follows: according to the primary topology, the edge 1 circuit breaker is not connected, so the value is 0. The generation strategy for connecting the edge 2 circuit breaker bay is as follows: according to the primary topology, the edge 2 circuit breaker bay is connected, the bay number of the edge 2 circuit breaker is 2, and the value is 2. The generation strategy for connecting the edge 1 bus group is as follows: according to the primary topology, the edge 1 bus bay bay has a bay number of 1, the edge circuit breaker bay is connected to the edge 1 bus bay, and the value of the connection to the edge 1 bus group is 1. The generation strategy for connecting the edge 1 bus group is as follows: when adding an IED, the branch number of the edge circuit breaker bay is set to 1, and the protection branch number of the edge 1 bus is 1. The edge 1 circuit breaker uses an expanded dataset, which defaults to 0.

[0051] The adaptive parameter is usually set to 0 by default, but can be manually specified when adaptation is required.

[0052] The configuration of automatic safety parameters can be determined by whether or not the substation is connected to an automatic safety device; this implementation does not impose such a limitation. Table 1 below shows the configuration parameters for the first circuit breaker protection device P_B5001A in the side circuit breaker bay.

[0055] This invention achieves efficient and accurate design of configuration-free parameters through automatic generation of topology association parameters and three-level strategy assignment, reducing manual intervention and solving the problems of parameter abstraction and error susceptibility in configuration-free technology. It realizes efficient and accurate configuration-free design of secondary equipment and provides key technical support for the construction of a new generation of high-reliability substations.
