[0026] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0027] The control method and device for simulating a break discharge process according to an embodiment of the present application are described below with reference to the accompanying drawings.

[0028] Figure 1 It is a schematic flowchart of a control method for simulating a break discharge process provided by an embodiment of the present application. As Figure 1 shown, it is executed by a control unit, and the method includes the following steps:

[0029] S101, adjust the initial states of the valves in the valve set according to the initial state information.

[0030] The valve set includes at least one of a first valve, a second valve, a third valve, and a break adjustment valve.

[0031] In some implementations, the control unit is a terminal such as a computer capable of implementing basic control functions. Based on the control unit, the opening and adjustment of each module are performed to reduce misoperations caused by manual processing.

[0032] In some implementations, the initial state information can be pre-configured information, and the initial state information includes the initial states of the valves. For example, if the initial state information indicates that the first valve is closed and the other valves are open, then according to the initial state information, the initial state of the first valve in the valve set is adjusted to closed, and the initial states of the other valves are adjusted to open; in this embodiment, the initial state information can be that the first valve, the third valve, and the break adjustment valve are closed, and the second valve is open. Based on this initial state information, the first valve, the third valve, and the break adjustment valve in the valve set are adjusted to closed, and the second valve is adjusted to open.

[0033] S102, based on the initial power, turn on the heating unit in the test body to heat the mixed fluid, and determine whether the heating unit meets the first determination condition of the temperature according to the temperature of the heating unit.

[0034] Optionally, the initial power can be a set value, and there is no specific limitation; that is, turn on the heating unit in the test body and set the power of the heating unit to this initial power; where the test body can be a core simulator.

[0035] In some implementations, the heating unit can be one or more heating rods, that is, the test body can include one or more heating rods; the heating rods operate according to the initial power to achieve heating of the mixed fluid.

[0036] Furthermore, obtain the temperature of the heating unit for measurement, that is, measure the temperature of one or more heating rods in the heating unit, and determine whether the heating unit meets the first determination condition of the temperature according to the temperature of the heating unit. In some implementations, the first determination condition can be that the temperature reaches a preset value. For example, when the temperature of the heating unit meets the preset value, it is determined that the heating unit meets the first determination condition of the temperature; otherwise, it is determined that the heating unit does not meet the first determination condition of the temperature.

[0037] S103, in response to the heating unit meeting the first determination condition, obtain and execute the control strategy to implement the simulation of the break spray test.

[0038] The control strategy includes power control of the heating unit based on the decay rule and state control of the valves in the valve set.

[0039] It can be understood that the decay rule refers to the rule of power decay of the heating unit during the actual break spray process. The power decay rule can be simulated according to the power decay during the actual break spray process, and power control is performed according to this power decay rule. For example, if the initial power is 10 and the power decay rule is to gradually decay by 1, then the power control of the heating unit based on the decay rule will change from the initial power of 10 to 9, 8 until the end of the test simulation.

[0040] In some implementations, the state control of the valves in the valve set is to change the open or closed state of the valves. During the break discharge test, the break adjustment valve is required to achieve the break discharge process. Therefore, the state control of the break adjustment valve is the open state. Correspondingly, the open or closed states of the first valve, the second valve, and the third valve are adaptively adjusted to ensure that the break discharge test can be achieved. In this implementation, the states of the valves during the break discharge stage are: the second valve is closed, and the first valve, the third valve, and the break adjustment valve are open.

[0041] In some implementations, the opening degree of the break adjustment valve can also be adjusted, and based on the opening degree of the break adjustment valve, the pressure of the test body is controlled to make it more conform to the actual pressure change during the break discharge process, achieving a better test effect.

[0042] In this embodiment, based on the control unit, the states of the first valve, the second valve, the third valve, and the break adjustment valve in the valve set are adjusted to the initial state at the start of the test, and the heating unit in the test body is turned on based on the initial power. When the temperature of the heating unit satisfies the first determination condition, the decay rule for power control is obtained to adjust the power and the valve states are controlled and adjusted to achieve efficient control of each valve and the heating unit in the test body during the test process. Controlling the power based on the decay rule is more in line with the decay trend of the reactor core, the test effect is better, and at the same time, misoperations are not likely to occur during the test process, and the test process is safer.

[0043] Based on the above embodiments, Figure 2 is a schematic flow chart of another control method for simulating the break discharge process provided by the embodiments of the present application. As Figure 2 shown, it is executed by the control unit, and the method includes the following steps:

[0044] S201, adjust the initial states of the valves in the valve set according to the initial state information.

[0045] In some implementations, the initial state information includes: the first valve, the third valve, and the break adjustment valve are closed, and the second valve is open; according to the initial state information, the initial states of the first valve, the third valve, and the break adjustment valve are controlled to be closed, and the initial state of the second valve is open.

[0046] In the embodiments of the present application, the implementation method of step S201 can be implemented in any one of the various embodiments of the present disclosure, and no limitation is made here and will not be elaborated further.

[0047] S202, turn on the heating unit in the test body based on the initial power to heat the mixed fluid, and determine whether the heating unit satisfies the first determination condition of the temperature according to the temperature of the heating unit.

[0048] In some implementations, the heating unit includes at least one heating rod, and the real-time temperature of each heating rod in the heating unit is obtained; optionally, one or more temperature measuring instruments, such as thermocouples or temperature sensors, can be arranged in the test body to measure the real-time temperature.

[0049] In response to the real-time temperature of any heating rod being greater than or equal to the set temperature threshold, it is determined that the heating unit meets the first determination condition for temperature; that is, when the temperature of any heating rod reaches the set temperature threshold, it is determined that the heating unit meets the first determination condition for temperature.

[0050] In the embodiments of the present application, the implementation method of step S202 can be implemented in any one of the embodiments of the present disclosure, and no limitation is made here and will not be elaborated further.

[0051] S203, in response to the heating unit meeting the first determination condition, obtain the power decay curve of the heating unit, and use the power decay curve as the decay rule to control the power of the heating unit, obtain the valve opening and closing information, and control the initial state of the valves in the valve set based on the valve opening and closing information.

[0052] In some implementations, the power decay curve describes the power decay process during the simulation test process, and can be obtained in advance by simulating the actual power decay. For example Figure 3 As shown, the power decay curve is obtained through the decay simulation of the core decay process. According to the power decay curve as the power decay rule, the power of the heating unit is controlled, that is, the power of the heating unit is controlled to change in real time according to the power decay curve to simulate the decay curve of the core decay process.

[0053] Optionally, the valve opening and closing information may include closing the second valve, opening the first valve, the third valve, and the break adjustment valve, which are test information configured in advance. Specifically, that is, the initial state of the second valve can be adjusted from open to closed based on the valve opening and closing information; in response to the second valve being completely closed, the initial states of the first valve, the third valve, and the break adjustment valve are adjusted from closed to open according to the valve opening and closing information.

[0054] In some implementations, the break adjustment valve can also be opened to a set opening, and the pressure drop curve of the test body is obtained. The pressure drop curve is used to describe the change trend of the pressure of the test body during the actual break discharge process, and can be obtained by simulating the change of pressure during the actual break discharge process, as Figure 4As shown; it can be understood that different opening degrees of the break adjustment valve have different effects on the pressure of the test body. Therefore, the pressure change of the test body can be correspondingly affected by adjusting the opening degree of the break adjustment valve, so that the pressure change of the test body conforms to the pressure change trend during the actual break discharge process. Therefore, the set opening degree of the break adjustment valve is adjusted according to the pressure drop curve to simulate the pressure change of the test body during the discharge process, making the test process more conform to the actual break discharge process.

[0055] Based on the control method of the above embodiments, a simulation of the break discharge process test is carried out. During the test process, test parameters such as the power of the heating unit, the pressure of the test body, and the flow rate change can be as Figure 5 Exemplarily shown, the control center can respond quickly according to the conditions during the test process and complete each control step in the order of the test process, which can improve the control effect and reduce the test error.

[0056] In this embodiment, at the initial stage of the test, the initial states of the valves in the valve set are adjusted, that is, the valves are adaptively opened and closed. Further, the heating unit inside the test body is started with the initial power to heat the mixed fluid, and it is determined whether to start the control of the discharge test based on whether the temperature of the heating unit meets the first determination condition. When the temperature of any heating rod measurement point in the heating unit reaches the set temperature threshold, the power decay curve of the heating unit is obtained to perform power knowledge on the heating unit, and the initial states of the valves are adjusted based on the valve opening and closing information. The opening degree of the break adjustment valve can also be adjusted to control the pressure change of the test body to conform to the corresponding pressure drop curve, achieving a better test simulation process while improving the rapid response during the test process, making the test process more conform to the actual break discharge process.

[0057] To implement the above embodiments, the present application also proposes a control device for simulating the break discharge process.

[0058] Figure 6 The structural schematic diagram of a control device for simulating the break discharge process provided by an embodiment of the present application. As Figure 6 Shown, the control device for simulating the break discharge process includes:

[0059] A control unit 601, a fluid generation unit 602, a heating unit 603, a first valve 10, a second valve 20, a third valve 30, and a break adjustment valve 40; wherein the fluid generation unit 602, the heating unit 603, the first valve 10, the second valve 20, the third valve 30, and the break adjustment valve 40 are connected by pipelines, the control unit 601 is respectively connected to the heating unit 603, the first valve 10, the second valve 20, the third valve 30, and the break adjustment valve 40, and the heating unit 603 is inside the test body.

[0060] The control unit 601 is configured to adjust the initial states of the first valve 10, the second valve 20, the third valve 30, and the break adjustment valve 40 according to the initial state information; turn on the heating unit 603 based on the initial power, and determine whether the heating unit 603 meets the first determination condition of the temperature according to the temperature of the heating unit 603; in response to the heating unit 603 meeting the first determination condition, obtain and execute a control strategy to simulate a break discharge test; wherein the control strategy includes power control of the heating unit 603 based on an attenuation rule and state control of the first valve 10, the second valve 20, the third valve 30, and the break adjustment valve 40.

[0061] The fluid generation unit 602 is configured to generate a mixed fluid and send the mixed fluid to the test body through a pipeline, the first valve 10, and the second valve 20.

[0062] The heating unit 603 in the test body is configured to heat the mixed fluid and send the mixed fluid to the break adjustment valve 40 through a pipeline and the third valve 30.

[0063] The break adjustment valve 40 is configured to simulate a break discharge.

[0064] In some implementations, the fluid generation unit 602 may include a saturated water generation module and a steam generation module. The saturated water generation module generates saturated water, and the steam module generates steam, so as to mix the saturated water and the steam to obtain a mixed fluid.

[0065] In some implementations, a fourth valve may further be included between the fluid generation unit 602 and the heating unit 603. The fourth valve is configured to adjust the flow rate of the mixed fluid flowing into the test body; optionally, the test body may be a core simulator, and the heating unit 603 is one or more heating rods.

[0066] In some implementations, the control unit 601 may receive the real-time temperature of each heating rod in the heating unit 603. In response to the temperature of any heating rod exceeding the set temperature threshold, it is determined that the heating unit 603 meets the first determination condition of the temperature; optionally, the temperature of the heating rod may be obtained by arranging temperature detection instruments, such as thermocouples and other instruments for temperature acquisition and real-time transmission to the control center, so that the control center can perform test control in a timely manner based on the changes in test data.

[0067] In response to the heating unit 603 satisfying the first determination condition, the control unit 601 may obtain the power decay curve of the heating unit 603, and use the power decay curve as a decay rule to perform power control on the heating unit 603; obtain the valve opening / closing information, and control the initial states of the first valve 10, the second valve 20, the third valve 30, and the break adjustment valve 40 based on the valve opening / closing information; wherein the power decay curve and the valve opening / closing information may be curve information obtained by advance simulation, for example, obtained by simulating the actual power decay, and adjust the power of the heating unit 603 in the test body according to the power decay curve to simulate the process of core decay.

[0068] Optionally, the valve opening / closing information may be to close the second valve 20, open the first valve 10, the third valve 30, and the break adjustment valve 40; the control unit 601 adjusts the initial state of the second valve 20 from open to closed based on the valve opening / closing information; in response to the second valve 20 being completely closed, adjusts the initial states of the first valve 10, the third valve 30, and the break adjustment valve 40 from closed to open according to the valve opening / closing information; in this embodiment, the second valve may be used to indicate whether the current test is started. When the heating unit 603 satisfies the first determination condition, close the second valve 20 to start the spray simulation test; after the second valve 20 is completely closed, open the first valve 10, the third valve 30, and the break adjustment valve 40 simultaneously; it can be understood that after the first valve 10 is opened, the mixed fluid will enter the test body through the connecting pipe, and further flow out from the third valve 30 after being processed by the test body to reach the break adjustment valve 40, and the break adjustment valve 40 realizes the spray process of the mixed fluid.

[0069] In some implementations, the control unit 601 opens the break adjustment valve 40 to a set opening degree, and obtains the pressure drop curve of the test body; adjusts the set opening degree of the break adjustment valve 40 according to the pressure drop curve to simulate the pressure change in the spray process; wherein the pressure drop curve is a curve obtained by advance simulation, for example, can be obtained by simulating the pressure change in the actual break spray process, and adjust the opening degree of the break adjustment valve 40 according to the pressure drop curve to simulate the pressure drop trend of the test body in the spray process and improve the test accuracy.

[0070] It should be noted that the foregoing explanation of the embodiment of the control method for simulating the break spray process also applies to the control device for simulating the break spray process of this embodiment, and will not be elaborated here.

[0071] In the embodiment of the present application, at the initial stage of the test, the control unit adjusts the initial states of the valves in the valve set, that is, adaptively opens and closes the valves. Further, the heating unit inside the test body is turned on with the initial power to heat the mixed fluid, and it is determined whether to start the control spray test based on whether the temperature of the heating unit meets the first determination condition. When the temperature of any heating rod measurement point in the heating unit reaches the set temperature threshold, the power decay curve of the heating unit is obtained to perform power common knowledge on the heating unit, and the initial states of the valves are adjusted based on the valve opening and closing information. The opening of the break adjustment valve can also be adjusted to control the pressure change of the test body to conform to the corresponding pressure drop curve, realizing a better test simulation process, making the test process more conform to the actual break spray process, reducing the misoperation behavior of manual processing, and more accurately simulating the test process with the power and pressure changes in the actual spray process, so as to obtain more effective test data.
