Description

Technical Field

[0001] The present application relates to the field of nuclear power plant control technology, and in particular to a method, device, storage medium, and equipment for controlling regulating rods of a fast reactor rod control system. Background Art

[0002] In the design and development of reactors for the first three generations of nuclear power plants, pressurized water reactors (PWRs) are currently the mainstream type of nuclear power plant worldwide, and their design methods and specifications are largely mature. The sodium-cooled fast reactor (SFR), the preferred reactor type for the fourth generation, does not currently offer a significant safety advantage over PWRs. However, its improved uranium resource utilization and proliferation characteristics make it highly attractive to various countries. Various fourth-generation nuclear energy technology companies are actively promoting demonstration projects and commercialization. my country is also gradually mastering fast reactor technology and has built a corresponding SFR demonstration plant.

[0003] A safety vulnerability of sodium-cooled fast reactors lies in the highly reactive chemical properties of the coolant sodium, which reacts violently with both air and water. In terms of reactivity feedback, a reduction in sodium in the core of a large sodium-cooled fast reactor can introduce positive reactivity feedback. The control rods of the demonstration fast reactor are used to adjust power distribution and fine-tune reactivity changes during rod movement, forming the first shutdown system. Achieving effective, precise, rapid response, and stable and reliable control methods for these rods is crucial. Traditional pressurized water reactor (PWR) control rod methods, with their slow response and complex control processes, are no longer sufficient for the new generation of sodium-cooled fast reactor control rods. Therefore, a rod velocity generation control method for the fast reactor rod control system, tailored to the practical needs of fast reactors, is needed. Summary of the Invention

[0022] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0023] In this embodiment, a method for controlling a regulating rod of a fast reactor rod control system is provided. Figure 1 As shown, the method includes:

[0024] Step 101: Obtain a main signal value corresponding to a main signal of a fast reactor rod control system.

[0025] Step 102: input the main signal value into a pre-built regulating rod control program, and determine the control signal value corresponding to the regulating rod control signal according to the main signal value and preset parameter signal data through the regulating rod control program, and generate a rod control signal according to the control signal value.

[0026] Step 103: Input the rod control signal into the fast reactor rod control system, so as to control the corresponding regulating rod of the fast reactor rod control system through the rod control signal.

[0027] Among them, the main signal includes a relative power deviation signal I1, an automatic signal I2 for the regulating rod to be put into operation, a rod lifting prohibition signal I3, and a short-time prohibition of regulating rod movement signal I4; the relative power deviation signal indicates the deviation between the reactor power and the power setting value, the automatic signal I2 for the regulating rod to be put into operation indicates whether the regulating rod is in the automatic control mode, the rod lifting prohibition signal indicates whether the regulating rod is prohibited from being lifted, and the short-time prohibition of regulating rod movement signal indicates whether there is an emergency situation that causes the regulating rod movement to be suspended; the preset parameter signal data includes a dead zone range, a hysteresis difference zone range, a linear growth zone range, and a maximum speed zone range corresponding to the relative power deviation; the regulating rod control signal includes an automatic regulating rod speed signal O1, an automatic regulating rod lifting signal O2, an automatic lowering signal O3, and an automatic stop signal O4.

[0028] In the embodiment of the present application, first, the core parameters of the operation of the reactor's fast reactor rod control system (i.e., the signal value of the main signal) are collected in real time through sensors, monitoring systems, etc., specifically including: relative power deviation signal: reflecting the difference between the real-time power of the reactor and the target set value, used to determine whether the regulating rod needs to be moved to maintain power stability; regulating rod automatic signal: indicating whether the regulating rod is currently in the automatic control mode to avoid conflicts between manual intervention and automatic logic; prohibition of rod lifting signal: forcibly prohibiting the lifting of the regulating rod under abnormal working conditions such as sodium leakage and sodium boiling to prevent reactivity from getting out of control; short-term prohibition of regulating rod action signal: in response to sudden emergencies (such as earthquakes and equipment failures), the regulation rod action is temporarily locked to prevent the expansion of the accident. Next, the main signal value is input into the regulating rod control program to generate control signals. The control program dynamically processes the input signal based on preset parameters. The core logic includes: a deadband range, which sets a tolerance threshold for power deviation. Regulation is triggered only when the deviation exceeds this range, avoiding mechanical fatigue caused by frequent operation; a hysteresis range, which uses a bidirectional buffer to eliminate signal jitter and prevent the regulating rod from repeatedly oscillating near the critical point; a linear growth range, which adjusts the rod speed proportionally to the deviation when the deviation exceeds the deadband, achieving precise linear compensation; and a maximum speed range, which limits the rod speed to match the fast reactor's thermal characteristics and prevent transient overshoot caused by sodium boiling. The program ultimately generates four types of control signals: an automatic rod speed signal, which dynamically adjusts the rod insertion speed based on the deviation; an automatic raising / lowering signal, which independently controls the bidirectional movement of the regulating rod; and an automatic stop signal, which immediately terminates the operation if the safety threshold is exceeded. Finally, the rod control signals are input into the fast reactor system to execute regulation, driving the regulating rod through the actuator.

[0029] By applying the technical solution of this embodiment, a rod control program is used to generate rod control signals for the regulating rods based on various main signals of the fast reactor rod control system and pre-set preset parameter signal data, thereby controlling the regulating rods of the fast reactor rod control system through the rod control signals. Through the coordinated innovation of the signal system and the control logic, the accuracy, response speed and safety of the sodium-cooled fast reactor regulating rod control are improved.

[0030] In an embodiment of the present application, optionally, the control signal value corresponding to the adjustment rod control signal is determined by the adjustment rod control program according to the main signal value and the preset parameter signal data, including: determining the preliminary adjustment rod automatic rod speed signal value according to the relative power deviation signal value and the preset parameter signal data by the adjustment rod control program, and determining the adjustment rod automatic rod speed signal value, the adjustment rod automatic lifting signal value, the adjustment rod automatic insertion signal value, and the adjustment rod automatic stop signal value according to the preliminary adjustment rod automatic rod speed signal value, the adjustment rod automatic signal value, the adjustment rod automatic signal value, the adjustment rod automatic lifting signal value, and the adjustment rod automatic insertion signal value.

[0031] In this embodiment, the regulating rod control program first calculates the relative power deviation signal value and the preset parameter signal data to determine the preliminary regulating rod automatic rod speed signal value, and then determines the regulating rod automatic rod speed signal value, the regulating rod automatic lifting signal value, the regulating rod automatic insertion signal value, and the regulating rod automatic stop signal value based on the preliminary regulating rod automatic rod speed signal value, the regulating rod automatic signal value, the regulating rod automatic input signal value, the prohibition of lifting the rod signal value, and the short-time prohibition of regulating rod action signal value.

[0032] In the embodiment of the present application, optionally, determining the preliminary regulating rod automatic rod speed signal value according to the relative power deviation signal value and the preset parameter signal data by the regulating rod control program includes:

[0033] If the relative power deviation signal value is within the dead zone range, determining that the initial adjustment rod automatic rod speed signal value is 0;

[0034] If the relative power deviation signal value is within the hysteresis error range, determining the preliminary regulating rod automatic rod speed signal value based on the minimum regulating rod speed and the positive or negative sign of the relative power deviation signal value;

[0035] If the relative power deviation signal value is in the linear growth region, determining the automatic rod speed signal value of the preliminary adjustment rod according to the linear growth function corresponding to the linear growth region and the positive or negative sign of the relative power deviation signal value;

[0036] If the relative power deviation signal value is in the maximum speed region, the preliminary adjustment rod automatic rod speed signal value is determined based on the maximum adjustment rod speed and the positive and negative signs of the relative power deviation signal value.

[0037] In this embodiment, the dead zone range, hysteresis zone range, linear growth zone range, and maximum speed zone range corresponding to the relative power deviation can be divided by multiple thresholds. Specifically, the division can be achieved based on three thresholds a, b, and c from small to large. Figure 2As shown, the deadband range is [-a, a), the hysteresis error range is [a, b) and [-b, -a), the linear growth range is [b, c) and [-c, -b), and the maximum speed range is less than -c or greater than c. When the relative power deviation signal value is within the preset deadband range, the power fluctuation is determined to be within the acceptable range and no adjustment rod action is required. At this time, the initial adjustment rod automatic rod speed signal value is set to 0 to avoid frequent starts and stops of the adjustment rod due to minor deviations, reducing mechanical wear and sodium working fluid disturbances. When the deviation exceeds the deadband but enters the hysteresis error range, the adjustment direction is determined based on the deviation sign (positive deviation requires raising the rod, negative deviation requires lowering the rod), and the minimum adjustment rod speed is used as the initial action speed to prevent the adjustment rod from oscillating near the critical point due to signal noise. When the deviation continues to expand into the linear growth range, the rod speed signal value and the deviation value are dynamically linked through a preset linear function. The deviation sign determines the adjustment direction (positive deviation requires raising the rod, negative deviation requires lowering the rod). When the deviation exceeds a safety threshold, the rod speed signal is limited to a preset maximum regulating rod speed to prevent sodium boiling or core power distribution distortion caused by overregulation. This regional dynamic control strategy significantly improves the accuracy, stability, and safety of regulating rod control in sodium-cooled fast reactors.

[0038] In a specific application scenario, assume that the initial automatic speed signal value of the regulating rod is L1. L1 is converted from the value of input I1 under different conditions. I1.v and I1.value both represent the relative power deviation signal value. Vmax represents the maximum regulating rod speed, and Vmin represents the minimum regulating rod speed. The specific condition characteristics are as follows:

[0039] If I1.v <= (-c), L1 output is -Vmax;

[0040] If I1.value>(-c)and I1.value<(-b), L1 output is 66.0*I1.value / (cb)+66.0*b / (cb)-Vmin based on the linear growth function;

[0041] If I1.value>=(-b) and I1.value<(-a), L1 output is -Vmin;

[0042] If I1.value>=(-a)and I1.value<=a, L1 output is 0.0;

[0043] If I1.value>=(a) and I1.value<(b), L1 output is -Vmin;

[0044] If I1.value>=(b) and I1.value<(c), L1 output is 66.0*I1.value / (cb)+66.0*b / (cb)+Vmin based on the linear growth function;

[0045] If I1.value>=c, L1 output is Vmax.

[0046] In the embodiment of the present application, optionally, according to the preliminary automatic speed signal value of the regulating rod, the automatic signal value of the regulating rod already put into operation, the prohibition signal value of the regulating rod lifting, and the short-time prohibition signal value of the regulating rod action, determining the automatic speed signal value of the regulating rod, the automatic raising signal value of the regulating rod, the automatic lowering signal value of the regulating rod, and the automatic stopping signal value of the regulating rod includes:

[0047] If the regulating rod has been put into automatic signal value is 0, and the short-time prohibition regulating rod action signal value is 0, then determine the regulating rod automatic rod speed signal value is 0, the regulating rod automatic lifting signal value is 0, the regulating rod automatic lowering signal value is 0, and the regulating rod automatic stop signal value is 1;

[0048] If the regulating rod has been put into automatic operation, the prohibition of lifting the regulating rod signal is 0, and the short-time prohibition of regulating rod movement signal is 0, then the intermediate regulating rod automatic rod speed signal value is determined based on the absolute value of the preliminary regulating rod automatic rod speed signal value, and the intermediate regulating rod automatic raising signal value, the intermediate regulating rod automatic lowering signal value, and the intermediate regulating rod automatic stopping signal value are determined based on the positive and negative signs of the preliminary regulating rod automatic rod speed signal value; the absolute value of the preliminary regulating rod automatic rod speed signal value is used as the regulating rod automatic rod speed signal value; when the preliminary regulating rod automatic rod speed signal value is positive, the regulating rod automatic raising signal value is determined to be 1, the regulating rod automatic lowering signal value is determined to be 0, and the regulating rod automatic stopping signal value is 0; when the preliminary regulating rod automatic rod speed signal value is negative, the regulating rod automatic raising signal value is determined to be 0, the regulating rod automatic lowering signal value is determined to be 1, and the regulating rod automatic stopping signal value is 0; when the preliminary regulating rod automatic rod speed signal value is 0, the regulating rod automatic raising signal value is determined to be 0, the regulating rod automatic lowering signal value is determined to be 0, and the regulating rod automatic stopping signal value is 1;

[0049] If the regulating rod has been put into automatic signal value 1, the prohibition of lifting the rod signal value is 1, and the short-time prohibition of regulating rod action signal value is 0, then the intermediate regulating rod automatic rod speed signal value, the intermediate regulating rod automatic lifting signal value, the intermediate regulating rod automatic insertion signal value and the intermediate regulating rod automatic stop signal value are determined based on the size and positive and negative signs of the preliminary regulating rod automatic rod speed signal value; when the preliminary regulating rod automatic rod speed signal value is non-negative, the regulating rod automatic rod speed signal value is determined to be 0, the regulating rod automatic lifting signal value is 0, the regulating rod automatic insertion signal value is 0, and the regulating rod automatic stop signal value is 1; when the preliminary regulating rod automatic rod speed signal value is negative, the regulating rod automatic rod speed signal value is determined to be the absolute value of the preliminary regulating rod automatic rod speed signal value, the regulating rod automatic lifting signal value is 0, the regulating rod automatic insertion signal value is 1, and the regulating rod automatic stop signal value is 0;

[0050] If the short-time prohibition of the adjustment rod action signal value is 1, the control signal value will not be output within the preset time length, and after the preset time length, the adjustment rod automatic rod speed signal value, the adjustment rod automatic lifting signal value, the adjustment rod automatic insertion signal value, and the adjustment rod automatic stop signal value are determined based on the preliminary adjustment rod automatic rod speed signal value, the adjustment rod automatic signal value and the prohibition of lifting the rod signal value.

[0051] In this embodiment, the preliminary rod speed signal and the safety interlock signal are integrated through four-level condition judgment to generate a control signal that can directly drive the actuator: the first, manual mode or emergency stop state: when the regulating rod has been put into automatic signal value I2.v=0 (manual mode) and the regulating rod action signal value I4.v=0 is temporarily prohibited, no matter what the value of I3.v is, the regulating rod automatic rod speed signal value O1.v=0, the regulating rod automatic lifting signal value O2.v=0, the regulating rod automatic insertion signal value O3.v=0, and the regulating rod automatic stop signal value O4.v=1 are forced to enter the safety holding state to prevent the manual mode from conflicting with the automatic logic, and at the same time serve as the default safety position in an unexpected state. Second, fully automatic safe operation state: When I2.v = 1, I4.v = 0, I3.v = 0, if L1 > 0, O2.v = 1, O3.v = 0, O4.v = 0; if L1 < 0, O2.v = 0, O3.v = 1, O4.v = 0; if L1 = 0, O2.v = 0, O3.v = 0, O4.v = 1. Third, prohibition of lifting intervention state: When I2.v = 1, I4.v = 0, I3.v = 1, L1 ≥ 0, then L1 = F(I1.v), O1.v = 0, O2.v = 0, O3.v = 0, O4.v = 1; L1 < 0, then L1 = F(I1.v), O1.v = |L1|, O2.v = 0, O3.v = 1, O4.v = 0. This logic limits dangerous movements under specific operating conditions while retaining necessary adjustment capabilities. The fourth type, short-term emergency lockout, occurs when I4.v = 1 (e.g., earthquake, equipment failure), completely freezing all control signal outputs for a preset duration (e.g., 2 seconds), and the actuator maintains its current state. After the freeze period, the control signal is recalculated based on the real-time signal value to avoid malfunctions caused by transient interference. The preset duration begins when I4.v = 1 occurs.

[0052] In the embodiment of the present application, optionally, determining the automatic speed signal value of the regulating rod, the automatic raising signal value of the regulating rod, the automatic lowering signal value of the regulating rod, and the automatic stop signal value of the regulating rod according to the preliminary automatic speed signal value of the regulating rod, the automatic signal value of the regulating rod already inserted, and the prohibition of raising the rod signal value includes:

[0053] If the regulating rod has been put into the automatic signal value is 0, then determine the regulating rod automatic rod speed signal value is 0, the regulating rod automatic lifting signal value is 0, the regulating rod automatic lowering signal value is 0, and the regulating rod automatic stop signal value is 1;

[0054] If the regulating rod has been put into automatic signal value 1, and the prohibition of lifting rod signal value 0, then determine the intermediate regulating rod automatic rod speed signal value based on the absolute value of the preliminary regulating rod automatic rod speed signal value, and determine the intermediate regulating rod automatic raising signal value, the intermediate regulating rod automatic lowering signal value and the intermediate regulating rod automatic stopping signal value based on the positive and negative signs of the preliminary regulating rod automatic rod speed signal value; take the absolute value of the preliminary regulating rod automatic rod speed signal value as the regulating rod automatic rod speed signal value; when the preliminary regulating rod automatic rod speed signal value is positive, determine the regulating rod automatic raising signal value to be 1, the regulating rod automatic lowering signal value to be 0, and the regulating rod automatic stopping signal value to be 0; when the preliminary regulating rod automatic rod speed signal value is negative, determine the regulating rod automatic raising signal value to be 0, the regulating rod automatic lowering signal value to be 1, and the regulating rod automatic stopping signal value to be 0; when the preliminary regulating rod automatic rod speed signal value is 0, determine the regulating rod automatic raising signal value to be 0, the regulating rod automatic lowering signal value to be 0, and the regulating rod automatic stopping signal value to be 1;

[0055] If the automatic signal value of the regulating rod has been put into use is 1, and the prohibition of lifting the rod signal value is 1, then the intermediate regulating rod automatic rod speed signal value, the intermediate regulating rod automatic lifting signal value, the intermediate regulating rod automatic insertion signal value and the intermediate regulating rod automatic stop signal value are determined based on the size and positive and negative signs of the preliminary regulating rod automatic rod speed signal value; when the preliminary regulating rod automatic rod speed signal value is non-negative, the regulating rod automatic rod speed signal value is determined to be 0, the regulating rod automatic lifting signal value is 0, the regulating rod automatic insertion signal value is 0, and the regulating rod automatic stop signal value is 1; when the preliminary regulating rod automatic rod speed signal value is negative, the regulating rod automatic rod speed signal value is determined to be the absolute value of the preliminary regulating rod automatic rod speed signal value, the regulating rod automatic lifting signal value is 0, the regulating rod automatic insertion signal value is 1, and the regulating rod automatic stop signal value is 0.

[0056] In this embodiment, at the end of the preset time duration during which the adjustment rod action signal value is prohibited from changing to 1 for a short period of time, the following logic is executed. If I2.v = 0, regardless of the value of I3, O1.v = 0, O2.v = 0, O3.v = 0, O4.v = 1, to prevent conflicts between manual operation and automatic logic, and serve as the default safety state when the system is abnormal. If I2.v = 1, I3.v = 0, O1.v = |L1|, in addition, if L1> 0, O2.v = 1, O3.v = 0, O4.v = 0; if L1< 0, O2.v = 0, O3.v = 1, O4.v = 0; if L1 = 0, O2.v = 0, O3.v = 0, O4.v = 1. Closed-loop compensation for power deviation is achieved, and speed and direction are directly driven by the preliminary calculation results, eliminating intermediate conversion delays. If I2.v = 1, I3.v = 1, and L1 ≥ 0, then O1.v = 0, O2.v = 0, O3.v = 0, and O4.v = 1. If I2.v = 1, I3.v = 1, and L1 < 0, then O1.v = |L1|, O2.v = 0, O3.v = 1, and O4.v = 0. Dangerous operating directions are restricted under specific operating conditions (e.g., prohibiting the lifting of the rod in the event of a sodium leak) while retaining the necessary power regulation capability (allowing the insertion of the rod to reduce power). This technical solution significantly improves the intrinsic safety level and adaptability to operating conditions of sodium-cooled fast reactor regulating rod control through nested safety logic and directional control constraints. Its core advantages are: multi-level safety protection gradient: from manual forced shutdown, directional analysis in automatic mode, to speed constraints for prohibiting rod lifting conditions, a safety barrier covering all operating scenarios is constructed; adaptation to sodium working fluid characteristics: the prohibition of rod lifting logic directly responds to unique risks such as sodium leakage and sodium boiling in sodium-cooled fast reactors, and avoids reactivity runaway through a "only decrease, not increase" strategy; closed-loop control robustness: speed absolute value mapping and directional sign analysis mechanism eliminate the risk of "positive and negative sign misjudgment" in traditional methods, and improve power regulation accuracy; human-machine collaborative safety boundary: manual mode forced shutdown and autonomous adjustment in automatic mode complement each other, preventing human error while retaining the accuracy of automated control.

[0057] In an embodiment of the present application, optionally, before the main signal value is input into a pre-built regulating rod control program, the method further includes: constructing a rod speed-relative power deviation function model with a preset parameter signal and a relative power deviation signal as input, and with a preliminary regulating rod automatic rod speed signal and a preliminary regulating rod direction as output, and establishing a first calculation module based on the rod speed-relative power deviation function model; constructing a rod speed-relative power deviation function model with an automatic signal value of the regulating rod, a prohibition of raising the rod signal value, and a short-time prohibition of regulating rod action signal value as input, and with an intermediate regulating rod automatic rod speed signal, an intermediate regulating rod automatic raising signal, an intermediate regulating rod automatic lowering signal, and an intermediate regulating rod automatic lowering signal as output. A second calculation module is constructed with the value taking mode of each automatic stop signal as output; a third calculation module is constructed with the automatic rod speed signal of the middle adjustment rod, the automatic lifting signal of the middle adjustment rod, the automatic insertion signal of the middle adjustment rod, and the automatic stop signal of the middle adjustment rod as input, and the automatic rod speed signal of the adjustment rod, the automatic lifting signal of the adjustment rod, the automatic insertion signal of the adjustment rod, and the automatic stop signal of the adjustment rod as output; based on the first calculation module, the second calculation module and the third calculation module, the adjustment rod control program is established, and the preset parameter signal data is written into the first calculation module of the adjustment rod control program.

[0058] In this embodiment, Figure 3 As shown, the control program is decomposed into three functional layers through modular design, achieving decoupling of signal processing, safety interlocks, and execution output. The specific construction process is as follows. The first calculation module: Inputs: relative power deviation signal value I1.v and preset parameter signal data (dead zone / hysteresis error zone / linear growth zone / maximum speed zone); Output: preliminary control rod automatic speed signal value L1; A piecewise function is used to convert the power deviation into a control rod speed requirement. The second calculation module: Inputs: control rod automatic engagement signal value I2.v, control rod lift prohibition signal value I3.v, short-term action prohibition signal value I4.v (including timing signal); Output: intermediate control signals (control rod speed / lift / drop / stop value selection). The third calculation module: Inputs: intermediate control signals (intermediate control rod automatic speed signal, intermediate control rod automatic lift signal, intermediate control rod automatic drop signal, intermediate control rod automatic stop signal); Outputs: control rod automatic speed signal, lift / drop / stop signals; Calculation of various control rod control signals based on the intermediate control signals. This improves program operation efficiency.

[0059] In specific application scenarios, the configuration of the adjustment rod control program can be achieved in the following ways: determine the method input and output and collect input signals according to the detection system requirements and algorithm needs; build the control system algorithm model (various calculation modules) in the domestic development environment, and compile to generate a graphical configuration file; import the algorithm graphical module exported from the configuration file into the DCS host computer software, build the input and output logic function diagram according to the system monitoring requirements, and compile to generate an executable file; download the executable file to the DCS to complete the connection of the input and output signals; and complete the design and specific application of the program.
