Description

Technical Field

[0001] The present invention belongs to the field of electrical simulation modeling, and particularly relates to an electrical simulation automatic modeling method, device and readable storage medium. Background Art

[0002] The simulation model of the electrical system in a nuclear power plant can perform real-time simulation calculations on parameters such as three-phase voltage / current, positive / negative / zero-sequence voltage / current, frequency, active power, and reactive power of the distribution network, and has the simulation ability to support the simulation of electrical load power consumption under different working conditions such as unit startup, grid connection, power increase and decrease, no-load and island operation, and power failure accidents. The electrical system can also supply power to equipment such as high-power motors, 380V power motors, downstream transformers, downstream distribution panels, and local boxes in the nuclear power plant.

[0003] A professional electrical system simulation model consists of two parts, namely an electrical load model and a distribution network model. Among them, to establish an electrical load model, information such as bus name, voltage level, switch number, equipment number, equipment name, rated power, and rated current needs to be obtained from the design input; to establish a distribution network model, the connections between upstream and downstream voltage buses and the connections between the main electrical equipment among them need to be obtained from the electrical single-line diagram in the order from top to bottom and from left to right.

[0004] The design information mainly concerned in establishing an electrical simulation model includes: the equipment code of the circuit breaker on the upstream incoming line of the system single-line diagram, its upstream and downstream voltage levels, and the system code of the incoming power supply; the equipment code of the motor load on the load feeder branch and its voltage level; the code of the local box on the load feeder branch and its voltage level; the type of contactor group in the control loop of the load equipment, that is, the control logic type in the secondary wiring diagram; the equipment code of the transformer, the equipment code of the contactor group, and the upstream and downstream voltage levels on the downstream low-voltage distribution panel branch; the equipment code of the charger on the DC bus, the equipment codes of the incoming and outgoing circuit breakers, the rated voltage on the DC side, and the rated voltage on the AC side; the equipment name of the inverter on the DC bus, the equipment codes of the incoming and outgoing circuit breakers, the rated voltage on the DC side, and the rated voltage on the AC side; the equipment name and rated capacity of the battery on the DC bus; the topological data information of the distribution network, that is, the original topological connection relationship representing the medium-voltage distribution network, etc.

[0005] In the past, nuclear power plants used a traditional model to verify electrical system simulation models within their platforms. Electrical engineers typically submitted design inputs such as system one-line diagrams and feeder tables. Electrical simulation engineers first manually built a distribution network topology model based on each one-line diagram. They then populated the electrical load model with data such as load device type, design power, and design current from the corresponding distribution feeder tables. Nuclear power plants have numerous electrical systems, and relying on this manual modeling approach presents the following technical challenges: First, labor costs are high and, due to the limited expertise of electrical simulation engineers, errors are likely to occur. Second, the appearance of simulation drawings differs significantly from electrical one-line diagrams, requiring design verifiers to interpret the simulation drawings. Third, the data transfer between design and simulation modeling is disconnected, significantly impacting the efficiency of electrical system simulation modeling. Furthermore, the low level of integrated collaborative participation of electrical professionals within the verification platform results in long verification cycles and low efficiency. This contradicts the efficient, collaborative, and intelligent design verification process advocated by digital nuclear power plants. Summary of the Invention

[0006] To address the shortcomings of the prior art, the present invention aims to provide an automated electrical simulation modeling method, device, and readable storage medium. By standardizing the design data in electrical distribution design drawings, this method achieves collaboration between design and information identification protocols. This method enables automated modeling from electrical design files to simulation models, primarily by automatically generating electrical load models and distribution network models, and automatically populating simulation model data from design data.

[0007] By directly regulating the form and content scope of the feeder design information of the electrical distribution system, and using information extraction and conversion tool software, the electrical simulation automatic modeling process can be automatically carried out after receiving the data, so that the electrical dedicated design software and the simulation verification platform electrical simulation modeling are seamlessly connected, which can improve the accuracy of data recognition and electrical modeling process, and is more suitable for the rapid automatic simulation modeling and design verification process of digital electrical professionals.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is an electrical simulation automatic modeling method, which includes the following steps:

[0009] S1: Obtain the original design file, sort out the electrical system single-line diagram, and define the typical upstream and downstream inlet and outlet line types;

[0010] S2: For each typical upstream and downstream inlet and outlet line type defined in step S1, combined with the characteristics of its electrical equipment and the needs of the simulation topology model, standardize the requirements for the topology information extraction content of its distribution network;

[0011] S3: Classify the electrical loads of the original design document, and specify the requirements for extracting the simulation model data of the electrical loads in combination with their characteristics;

[0012] S4: Generate an electrical simulation data interface file according to the specifications in steps S2 and S3;

[0013] S5: Sort out the feeder tables of electrical systems with different voltage levels in the original design document, and develop unit simulation components corresponding to each unit component in the original design document in the electrical modeling software environment;

[0014] S6: Use the simulation modeling software to import the electrical simulation data interface file generated in step S4 to generate an electrical simulation model format file, and at the same time load the unit simulation components developed in step S5, and use the simulation modeling software to edit and compile it to generate an executable electrical simulation model.

[0015] Further, in step S4, select the electrical distribution feeder table as the electrical simulation data interface file.

[0016] Further, step S1 includes sub-steps:

[0017] S101: Conduct a first-level classification of the single-line diagrams of electrical systems with different voltage levels, current types, and distribution methods according to the types of electrical equipment flowing through, and the types of electrical equipment include chargers, transformers, battery packs, and inverters;

[0018] S102: On the basis of the first-level classification, conduct a second-level classification by judging whether the single-line diagram of the electrical system is powered after being switched and controlled by a static switch.

[0019] Further, the topological information of the distribution network includes the connection between busbars through incoming and outgoing line branches, the upstream and downstream connection between electrical equipment on each incoming and outgoing branch, and the connection between load equipment under the busbar. The connection information between two busbars is characterized by selecting the equipment code of a key equipment as the characteristic data, and it is stipulated that the outgoing line branch of the upstream busbar and the incoming line branch of the downstream busbar need to contain this characteristic data information at the same time.

[0020] Further, step S2 includes: First, stipulate that the electrical simulation data interface needs to include the types of incoming and outgoing lines, and then standardize them one by one according to the types of incoming and outgoing lines.

[0021] Further, the standardization one by one according to the types of incoming and outgoing lines includes that for the incoming line branch switched by a static switch, it is necessary to distinguish the branch on the inverter side of the static switch, the branch on the transformer side of the static switch, and the fixed connection relationship of the static switch itself, the equipment code of the inverter on the inverter side, the code of the upstream busbar, the equipment code of the transformer on the transformer side, and the equipment code of the circuit breaker on the output side of the static switch.

[0022] Further, step S3 includes receiving the load design parameter data in the electrical distribution feeder tables, the single-line diagram of the electrical system, and the data table of the working medium flow rate and power relationship for different voltage levels or types in the power plant system, and converting it into the electrical load simulation calculation information required for a specific electrical simulation model.

[0023] Further, step S3 includes dividing the loads according to the influence degree of the equipment power consumption change under different working conditions and selecting characteristic identifiers.

[0024] For low-voltage infrequently operated circuit type loads, the corresponding load simulation model may not be associated with the process simulation model, and its power consumption can be simulated according to the rated power in the feeder table.

[0025] For electrical equipment whose power consumption is greatly affected by specific operating conditions, it is necessary to define the associated relationship data with the process simulation model. The definition specification requires that the I d-code column in the feeder table must be the item number of the corresponding process equipment.

[0026] An electrical simulation automatic modeling device, the device includes:

[0027] The upstream and downstream bus in-out line type definition module is used to receive the single-line diagram of the electrical system with different voltage levels or types in the power plant system and define several electrical distribution system in-out line types with typical topological characteristics.

[0028] The distribution network topology information specification module is used to receive the electrical distribution system in-out line type data with typical topological characteristics defined by the upstream and downstream bus in-out line type definition module and convert it into the distribution network topology information required for specific simulation models corresponding to each typical topological characteristic.

[0029] The load model data specification module is used to receive the load design parameter data in the electrical distribution feeder tables, the single-line diagram of the electrical system, and the data table of the working medium flow rate and power relationship for different voltage levels or types in the power plant system, and convert it into the electrical load simulation calculation information required for a specific electrical simulation model.

[0030] The electrical simulation data interface generation module is used to receive the distribution network topology information converted by the distribution network topology information specification module and the electrical load simulation calculation information from the load model data specification module, parse and comprehensively configure the above information to generate a standardized electrical simulation data interface file.

[0031] The simulation unit component creation module is used to develop unit simulation components such as circuit breakers, transformers, electric valve loads, fan or pump loads, and buses that correspond to electrical design.

[0032] The interface data reading and conversion calculation module is used to receive the electrical simulation standard interface data generated by the electrical simulation data interface generation module, and generate a simulation model text file that can be recognized by the simulation support platform after reading and conversion.

[0033] The electrical simulation model generation module is used to apply professional simulation support platform software to receive the simulation model text file converted by the interface data reading and conversion calculation module, and at the same time load the unit simulation components generated by the simulation unit component creation module. After compilation and debugging, a simulation model that can run on the professional simulation support platform and perform electrical function calculations is generated.

[0034] A computer-readable storage medium stores an implementation program for information transmission. When the program is executed by a processor, it implements the steps in an electrical simulation automatic modeling method and its optional implementation manners.

[0035] The effect of the present invention is as follows: An electrical simulation automatic modeling method, device and readable storage medium disclosed by the present invention, by adopting the specification of the feeder design information of the electrical distribution system in terms of both form and content scope, and developing information extraction and conversion tool software, gets rid of the modeling working mode that depends on extracting configuration data between single-line diagrams of electrical systems at various voltage levels and multiple different feeder tables at the same time, forms a data interaction form specification between the electrical design platform and the simulation verification platform, and improves the practicability of the electrical simulation modeling technology. It enhances the automation ability and performance of electrical system simulation modeling, improves the consistency between the simulation model drawings and the design drawings, reduces the manual error rate, saves manual time-consuming, and ultimately improves the work efficiency of electrical simulation modeling and related design verification. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 It is a method flow chart of an electrical simulation automatic modeling method described in the present invention;

[0037] Figure 2 It is a structural schematic diagram of an electrical simulation automatic modeling device described in the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0039] Embodiment 1

[0040] As Figure 1 shown, an electrical simulation automatic modeling method described in the present invention includes the following steps:

[0041] S1: Summarize all design documents related to electrical simulation, sort out the electrical system single-line diagrams for different voltage levels, current types and distribution methods, and define the typical upstream and downstream inlet and outlet line types.

[0042] The basic data interface file should retain the original electrical design data file format as much as possible to minimize changes to the electrical data format and facilitate docking with the electrical design platform. Therefore, the original electrical distribution feeder table is selected as the basic electrical simulation data interface file.

[0043] Distribution systems are connected by bus voltage level. Most high-voltage buses provide power to lower-voltage buses, with a small number of interconnected buses of the same voltage level. Bus current types include AC and DC. Some electrical systems use static switches to select from multiple upstream power sources. Different electrical systems have different types of upstream incoming bus branches and downstream branches to other buses. For upstream incoming bus types, a primary classification is first performed based on the type of electrical equipment flowing through them, including chargers, transformers (voltage regulators), battery packs, and inverters. Based on this primary classification, a secondary classification is performed based on whether the power is supplied through static switches. Furthermore, classification can be performed based on whether the power is connected to a bus of the same level or if it is supplied outside the design scope. A total of 10 incoming bus types are defined, and similarly, five outgoing bus types are defined.

[0044] S2: For each typical incoming and outgoing line type, combined with the characteristics of its electrical equipment and the needs of the simulation topology model, standardize the topology information requirements of the distribution network.

[0045] The topological information of the distribution network includes the connection between busbars through incoming and outgoing line branches, the upstream and downstream connection between electrical equipment on each incoming and outgoing branch, and the connection of load equipment under the busbar. The connection information between the two busbars is obtained by selecting the equipment code of a key equipment as the characteristic data, and stipulating that the outgoing branch of the upstream busbar and the incoming branch of the downstream busbar must also contain the characteristic data information. For example, if the upstream DC of the incoming line is supplied by an inverter (not through a static switch), the bus feeder table of this system provides a corresponding relationship with the upstream busbar through the same inverter code. Different electrical systems have different types of upstream incoming branch of the busbar power supply and downstream branches to other busbars, and the types of electrical equipment in the corresponding branches and the connection relationship between equipment are also different. First, it is stipulated that the interface with the electrical simulation data must include the input and output line types, and then standardize them one by one according to the type. For example, for the incoming branch switched by the static switch, it is necessary to distinguish the fixed connection relationship between the static switch inverter side branch and the transformer side branch and the static switch itself, the inverter device code on the inverter side, the upstream bus code, the transformer device code on the transformer side, the device code of the circuit breaker on the output side of the static switch (the incoming side of the bus at this level), etc.

[0046] S3: Classify the electrical loads according to the requirements of the electrical load simulation model, and combine their characteristics to standardize the requirements for extracting simulation model data of the electrical loads.

[0047] The loads of the distribution system are divided into multiple types of load branches such as medium-voltage, low-voltage infrequently operated circuit type, low-voltage reversible motor type, and single-direction rotating motor type. The key focus of electrical design verification is to check whether the electrical loads of the distribution system meet the design requirements and are matched with the selected electrical equipment types under different operating conditions of nuclear power plants. Corresponding to different simulation depth requirements, further simulation is carried out, and the data content requirements of the simulation model are different. First, divide the loads according to the degree of influence on the electrical consumption change of equipment under different conditions and select characteristic identifiers. For example, for low-voltage infrequently operated circuit type loads such as rectifier power supplies, heaters, and lighting, "breaker feeder circuits" are used in the electrical feeder design. These loads do not receive control signals, and their electricity consumption has nothing to do with the operating conditions. They can be regarded as being powered on all the time. The corresponding load simulation model does not need to be associated with the process simulation model, and its electricity consumption can be simulated according to the rated power in the feeder table. Therefore, the electrical simulation load requires the "breaker model" in the feeder table to provide typical characteristic information (such as starting with the letter "DL"). Secondly, for electrical equipment whose electricity consumption is greatly affected by specific operating conditions, it is necessary to define the data of the association relationship with the process simulation model. For example, for reversible motor type loads such as various pumps and fans, "fuse-contactor feeder circuits" are used in the electrical feeder design. Defining its electrical simulation load requires the "fuse-contactor model" in the feeder table to provide typical characteristic information (such as starting with the letter "CF I"). Its electricity consumption varies with the operating conditions of the process system equipment, and the corresponding load simulation model needs to consider being associated with the process simulation model. Therefore, the definition specification requires that the I d-code (encoding) column in the feeder table must be the tag number of the corresponding process equipment, such as WSC002PO.

[0048] Receive the load design parameter data in the electrical distribution feeder tables, secondary single-line diagrams, and working medium flow and power relationship data tables of different voltage levels or types in the power plant system, and convert them into the electrical load simulation calculation information required by the specific electrical simulation model.

[0049] S4: Generate an electrical simulation data interface file

[0050] According to the specifications in Step S2 and Step S3, supplement the data requirements for the newly added distribution network topology and electrical loads into the original distribution system feeder table to generate an electrical simulation data interface file that meets the data form and content requirements for automatic modeling in the electrical specialty.

[0051] S5: Create unit simulation components

[0052] Sort out the feeder tables of electrical systems with different voltage levels, and summarize each unit component within the scope of electrical design. Then, in the nuclear power plant electrical modeling software environment, develop unit simulation components such as circuit breakers, transformers, electric valve loads, fan or pump loads, and busbars that correspond to the electrical design.

[0053] For the large number of feeder branches in the low-voltage distribution system, the distribution panel is a feeder simulation unit component, which can simplify the structure and quantity of electrical simulation drawings and facilitate the quick search for load devices. Develop an electrical simulation distribution panel component suitable for the structure of the feeder table to convert the layout information of the feeder table into the corresponding simulation distribution panel.

[0054] S6: Generate an electrical simulation model

[0055] Use the simulation modeling software to automatically import the electrical simulation data interface file generated in step S4 to generate an electrical simulation model format file. At the same time, load the unit simulation components developed in step S5, and use the simulation modeling software to edit and compile them to generate an executable electrical simulation model.

[0056] As can be seen from the above embodiments, an automatic electrical simulation modeling method disclosed by the present invention, by establishing data extraction rules, developing an automatic conversion tool software, automatically importing an electrical simulation data interface file, extracting and converting information into an electrical simulation model format file, and finally generating an electrical simulation model that can be recognized and edited into an executable one by the simulation modeling software. By adopting the specification of the feeder design information of the electrical distribution system in terms of both form and content scope, and developing an information extraction and conversion tool software, it gets rid of the modeling work mode that depends on extracting configuration data from the single-line diagrams of electrical systems with different voltage levels and multiple different feeder tables at the same time, forms a formal specification for data interaction between the electrical design platform and the simulation verification platform, and improves the practicality of the electrical simulation modeling technology.

[0057] Improve the automation ability and performance of electrical system simulation modeling, improve the consistency between the simulation model drawings and the design drawings, reduce the manual error rate, save manual time-consuming, and ultimately improve the work efficiency of electrical simulation modeling and related design verification.
