[0025] In order to enable those skilled in the art to better understand the present invention, the following will be combined with the drawings in this application to clearly and completely describe the technical solutions in the present invention. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] It should be noted that the terms "first", "second", etc. in the description, claims and drawings of this application are used to distinguish different objects, rather than to limit a specific order.

[0027] According to one aspect of the present invention, a core simulator is provided. Figure 1 A schematic diagram of the core simulator provided for this application is shown in FIG. Figure 1 As shown, the core simulator includes:

[0028] The signal converter module 11 is configured to receive a physical signal from the first core control system and convert the physical signal into a voltage signal having a predetermined amplitude; and receive a characteristic signal output by the integrated circuit module 13 and convert the characteristic signal into a target physical signal in the first core control system;

[0029] The signal converter module 11 serves as a controlled source and includes multiple signal converters, wherein the signal converters are composed of multiple types of controlled sources. For example, the signal converters can be composed of a current-controlled voltage source, a current-controlled current source, a voltage-controlled current source, and a voltage-controlled voltage source. The signal converter module 11 can access a variety of signals, providing a rich variety of signal input types, strong adaptability, and the ability to represent real physical parameters. The predetermined amplitude can be flexibly set according to the needs of the application scenario.

[0030] The above-mentioned first core control system is used as a verification object, which includes but is not limited to a power regulation system, a rod drive system, a rod control system, a rod position system, and a nuclear measurement system.

[0031] It should be noted that the physical signals corresponding to the power regulation system include but are not limited to the initial power signal and the speed regulation signal; the physical signals corresponding to the rod drive system include but are not limited to the rod position signal. The target physical signals include but are not limited to the normalized power signal and the speed regulation signal.

[0032] The integrated circuit module 13 is connected to the signal converter module 11 and is configured to receive the voltage signal and a preset given signal from the second core control system, and to perform real-time calculations on the voltage signal and the given signal based on a pre-programmed core model to obtain a characteristic signal. The core model is obtained by mapping a hardware-based digital circuit based on the core's physical model.

[0033] The characteristic signal is a signal used to describe signal characteristics in signal processing. It can be a transformation or extraction of the original signal, used to represent certain specific properties or characteristics of the signal. For example, characteristic signals include but are not limited to normalized power signals.

[0034] The host computer 15 is connected to the integrated circuit module 13 and is used to monitor the behavioral characteristics and operating condition signals of the core model and to re-express the physical signals.

[0035] The host computer includes a computer, which includes a dedicated power electronics design platform and a built core model. The computer completes the hardware characterization of the core and converts the core interface signals through a communication interface.

[0036] The core model's behavioral characteristics represent the physical processes and behaviors within the nuclear reactor core. These characteristics can be captured by monitoring operating signals. These operating signals represent various parameters and status signals during reactor operation, such as temperature, pressure, flow rate, and power. By monitoring and analyzing these operating signals, we can understand the core model's behavioral characteristics, including thermal, dynamic, and nuclear physics characteristics.

[0037] Physical signal reformulation involves processing and transforming the original physical signal to better represent its characteristics and information. This can be achieved through signal processing techniques such as filtering, noise reduction, and feature extraction. By reformulating the physical signal, useful information can be extracted, noise and interference removed, leading to better understanding and analysis of the signal.

[0038] Physical signal re-expression plays a crucial role in monitoring core models. By re-expressing operating condition signals, characteristic signals related to core behavior can be extracted, enabling better monitoring and analysis of core status and performance. These characteristic signals can be used for fault detection, anomaly identification, and performance evaluation, supporting the safe operation of nuclear reactors.

[0039] The core simulator described above is combined with a control method to achieve the purpose of verifying the control characteristics of the system and subsystems.

[0040] Optionally, during the operation of the core simulator, the signal of the object selector of the integrated circuit module 13 is identified to complete the confirmation of the system verification object, and the selection of the logical operation condition set and the signal validity characterization of the signal unit are completed. The host computer's dedicated power electronics verification platform should have been connected to the integrated circuit module 13 and completed the corresponding hardware mapping, and the core interface conversion signal status is confirmed by the host computer. After the above status is correct, the start switch of the integrated circuit module 13 can be enabled, and all timing expressions in the logical operation condition set can be completed, and finally the characteristic result expression is obtained.

[0041] Optionally, the core simulator can be used to implement functional verification such as electrical and logical functions, performance verification, etc. of subsystems, redundant systems, and cascaded combination systems; and multiple cycle verifications can be performed through one-touch reset of the integrated circuit module 13 .

[0042] In the invention, the core simulator uses a signal converter module to convert and access the system signal, and uses a core model to perform real-time calculations on the core. The system signal can be directly directed to the engineering system, thereby solving the technical problems in the related technologies that there is no direct correlation between the full process design and implementation of the control system in the field involved, and there are technical problems such as a single signal type, poor accessibility, poor signal physical parameter characterization capability, fuzzy control feature confirmability, and poor verification object expansibility. The technical effect of improving the rationality, relevance, verifiability, expansibility of the control system design and the characterization capability of electrical parameters is achieved.

[0043] Furthermore, the core simulator is fully powered by real-time computations using modeled hardware. By setting verification objects, operating according to system logic, and combining system and subsystem control requirements, the integrated circuit module 13 and specific signal timings enable real-time signal computation and logic verification for the entire system and subsystems in real-time mode, achieving design optimization and verification of system functionality and performance. The host computer, combined with a dedicated power electronics design platform, extracts characteristic signals through a communication interface, improving the conversion and testability of state data and enhancing the system's digital representation capabilities, thereby accelerating design effectiveness and testability.

[0044] When the power regulation system is connected, the power regulation system transmits the power signal and speed control signal to the integrated circuit module 13 via a signal converter. Based on the initial power signal and the rod position signal of the rod drive system of the integrated circuit module 13, the integrated circuit module 13 completes the normalized power output of the core model and connects it to the power feedback input of the power regulation system via the signal converter, thus completing the real-time simulation of the power regulation system. When the rod drive system is connected, the rod position signal of the rod drive system is transmitted to the integrated circuit module 13 via a signal converter. Based on the rod position signal and the initial power signal of the power regulation system of the integrated circuit module 13, the integrated circuit module 13 completes the normalized power output of the core model and calculates the speed control signal through the power regulation system, thus completing the real-time simulation of the rod drive system.

[0045] Optionally, the signal converter module 11 is used to receive and convert physical signals such as rod position, power setting, and speed control signals from the power regulation system and rod drive system, uniformly converting various current and voltage signals into voltage signals of predetermined amplitudes. The integrated circuit module 13 receives signals from the signal converter and outputs characteristic signals based on a fully hardware-based core model. The host computer 15 monitors the core model's behavioral characteristics and operating condition signals, as well as re-expresses the physical signals.

[0046] In an optional embodiment, the integrated circuit module 13 includes: an initial power signal unit, which is used to set the initial power signal in the power regulation system when the second core control system is a power regulation system.

[0047] The initial power signal unit is used to set the initial power signal of the core.

[0048] In an optional embodiment, the integrated circuit module 13 includes: a speed regulation signal unit, configured to integrate the speed regulation signal to generate a rod position signal when the physical signal in the first core control system includes the speed regulation signal.

[0049] For example, the speed control signal unit is used to integrate the speed control signal and form a rod position signal, and participate in the normalized power output of the core. The normalized power output is the power normalized output value calculated in real time, which is the power output of the entire system and participates in the real-time feedback calculation of the system.

[0050] In an optional embodiment, the above-mentioned integrated circuit module 13 includes: a normalized power output unit, which is used to output a normalized power signal, wherein when the first core control system is a power regulation system, the normalized power signal is returned to the power regulation system as the target physical signal of the power regulation system; when the first core control system is a rod drive system, the normalized power signal is used as an input quantity to calculate the speed regulation signal.

[0051] For example, based on the stick position signal of the integrated circuit module 13 and the initialized power signal and taking them as input, the hardware-based digital circuit mapping completes the calculation and realizes the normalized power signal output.

[0052] In an optional embodiment, the integrated circuit module 13 includes: an object selector for selecting any one of the power regulation system and the rod drive system as the first core control system, wherein the unselected system serves as the second core control system.

[0053] For example, the object selector is used to select the object to be verified, and the power regulation system or the rod drive system can be selected for verification according to the actual verification object needs.

[0054] In an optional embodiment, the integrated circuit module 13 includes: a start switch, which is used to control the integrated circuit module 13 to start and run real-time calculation after the initialization state of the integrated circuit module 13 is confirmed.

[0055] For example, the integrated circuit module 13 selects the core model and the signal flow according to the object selector, and after the start switch is used to confirm all initial states, the real-time calculation of the integrated circuit module 13 is started and runs.

[0056] In an optional embodiment, the integrated circuit module 13 includes: a state resetting unit, configured to reset the integrated circuit module 13 to an initialization state.

[0057] For example, the state reset unit can reset the state of the integrated circuit module 13 to implement multiple independent real-time calculations.

[0058] In an optional embodiment, the integrated circuit module 13 includes: a signal generating unit, configured to convert the normalized power signal into a characteristic signal by utilizing a conversion relationship between amplitude and frequency.

[0059] For example, the signal generating unit is used to express the normalized power output as a characteristic signal, complete the corresponding conversion relationship between amplitude and frequency, and output it through the port.

[0060] In an optional embodiment, the integrated circuit module 13 includes: a logic operation condition set unit, which is used to perturb the normalized power signal and / or the rod position signal based on the logic operation in the logic operation condition set.

[0061] A logical operating condition set can be used to describe different operating states, working modes, or operating conditions of a system. A logical operating condition set typically consists of a series of logical operations and conditions, which can be logical calculations, judgment statements, trigger conditions, and more. By combining and judging these operations and conditions, operating conditions can be classified and controlled. For example, a logical operating condition set unit can perform perturbations on power and rod position signals, enabling the selection of these logical operations as needed.

[0062] In an optional embodiment, the integrated circuit module 13 includes: a core hardware mapping unit, which is used to map the operating status of the integrated circuit module 13 into a hardware status.

[0063] For example, the core hardware mapping unit can communicate the state of the on-chip real-time unit to express the hardware state. The core hardware mapping unit stores the core model. In the specific implementation process, the core model is burned into the integrated circuit module 13 by the host computer 15, forming the core hardware mapping unit.

[0064] In an optional embodiment, the integrated circuit module 13 includes: a virtual signal interface unit for restoring the physical signal in the first core control system.

[0065] For example, the virtual signal interface unit completes the restoration of the physical signal for expressing the internal real physical signal. In addition, the virtual signal interface unit is also used to receive or output the corresponding signal.

[0066] The optional embodiments of the present application are described in detail below.

[0067] Figure 2 This is a schematic diagram of the core simulator provided in this application when it is connected to the power regulation system, as shown in Figure 2 As shown, if the verification object is a power regulation system, the integrated circuit module 13 is connected to the initial power signal and speed regulation signal of the power regulation system. The physical property characterization of the signal is completed by the signal converter module 11 and the integrated circuit module 13. The integrated circuit module 13 completes the normalized power signal output according to the core model in the core hardware mapping unit, and the virtual signal interface unit and signal converter of the integrated circuit module 13 are output to the power feedback to complete the system access integrity. The verification purpose is to realize the characteristic signal deployment and operation preparation by the host computer 15 through the logical operation condition set. At the same time, the host computer 15 monitors the characteristic signal through a dedicated platform software tool.

[0068] If the power regulation system is connected and the core simulator is in working state, the integrated circuit module 13 monitors the initial power setting and calculates the power feedback value of the normalized power signal in real time based on the value of the speed regulation signal by the core hardware mapping unit.

[0069] If the initial power signal enters a steady state after the calculated power feedback, a transient change setting can be performed to achieve a given power disturbance. If the speed regulation signal changes, it is a real-time dynamic disturbance under speed regulation, and the disturbance results can be represented on the host computer.

[0070] Figure 3 This is a schematic diagram of the core simulator provided in this application when it is connected to the rod drive system, as shown in Figure 3 As shown, if the verification target is the rod drive system, the integrated circuit module 13 accesses the rod position signal of the rod drive system. The physical properties of this signal are characterized by the signal converter module 11 and the integrated circuit module 13. The integrated circuit module 13 determines the internal initial power signal based on the operating condition set and outputs a normalized power signal based on the core model in the core hardware mapping unit. The virtual signal interface unit and signal converter of the integrated circuit module 13 output the signal to the speed control signal, completing the system signal access integrity. For verification purposes, the host computer 15 implements characteristic signal deployment and operational preparation through the logical operation operating condition set. Simultaneously, the host computer 15 monitors the characteristic signal using dedicated platform software tools.

[0071] If the rod drive system is connected and the core simulator is already operational, the integrated circuit module 13 monitors the rod position signal setting. Based on the value of the initial power signal, the core hardware mapping unit calculates the power feedback value of the normalized power signal in real time. After the integrated circuit module 13 completes the calculation, the speed control signal is output and transmitted to the rod drive system through the signal converter.

[0072] If the rod position signal enters a steady state after the power feedback is calculated, a transient change setting can be performed to achieve a given disturbance of the rod position, and the disturbance results can be represented on the host computer.

The initial power signal unit is used to set the initial power signal of the core. The speed control signal unit is used to integrate and form the rod position signal and participate in the normalized power signal output of the core. The normalized power signal output is a real-time calculated power normalized output value, which represents the power output of the entire system and participates in the real-time feedback calculation of the system. The object selector is used to select the verification object, and can be used to verify the power regulation system or the rod drive system according to the actual verification object. The integrated circuit module 13 selects the core model and signal flow according to the object selector. The start switch is used to start and run the real-time calculation of the integrated circuit module 13 after all initial states are confirmed. The state reset unit is used to reset the state of the full real-time on-chip unit to realize multiple independent real-time calculations. The signal generation unit is used to express the normalized power output as a characteristic signal, such as completing the corresponding conversion relationship between amplitude and frequency and outputting it through the port. The logical operation condition set unit is used to perform perturbations of the power and rod position signals, and can complete the above-mentioned logical operation selection as needed. The core hardware mapping unit is used to express the hardware state of the integrated circuit module 13 through communication. The virtual signal interface unit is used to restore the physical signal and express the internal real physical signal. The communication interface is used for data communication between the integrated circuit module 13 and the host computer 15 .

[0074] Optionally, the core hardware mapping unit and the virtual signal interface unit can be combined into one unit.

[0075] It should be noted that, in the present invention, the core simulator has the following advantages:

[0076] (1) The use of a full range of signal converters, combined with the internal integrated circuit module 13, provides a wide range of signal access types and complete and accurate physical parameter expression.
