[0060] For ease of understanding, the relevant content of the voltage regulator will be introduced first in this embodiment.
[0061] As a key component for system loop pressure control, the voltage regulator typically includes a swirl tube, spray tube, heater, and safety valve. The voltage regulator controls the system loop pressure by mitigating pressure rises through spraying or pressure drops through heating. During the dynamic adjustment process of the voltage regulator, the actions of its swirl tube, spray tube, safety valve, and heater cause internal heat and mass transfer phenomena, including spray condensation, vapor zone condensation, liquid zone evaporation, interfacial heat transfer, and wall condensation. Furthermore, when supercooled water flows into the bottom of the liquid zone from the swirl tube or spray water falls onto the top of the liquid zone, it can cause thermal stratification in the liquid zone of the voltage regulator. In practice, these factors significantly affect the calculation of voltage regulator parameters; therefore, these physical processes should be fully considered when establishing the mathematical model.
[0062] In related technologies, a two-zone or three-zone model of the voltage regulator is established, and the parameters of the voltage regulator are calculated based on the two-zone or three-zone model. However, the wall condensation and interface heat transfer issues are not considered in the calculation process. Therefore, this method of calculating voltage regulator parameters may lead to low accuracy of parameter calculation.
[0063] The voltage regulator parameter determination method, apparatus, electronic device, medium, and program product provided in this application embodiment obtain the first structural parameter information, total mass, and total energy of the target voltage regulator at the current time point, as well as the vapor-liquid enthalpy of the target voltage regulator at the previous time point; then, based on the vapor-liquid enthalpy and the vapor-liquid heat and mass transfer constitutive equation at the previous time point, determine the heat and mass transfer of the target voltage regulator at the current time point; next, based on the first structural parameter information and the heat and mass transfer, determine the liquid region mass and liquid region enthalpy of the target voltage regulator at the current time point; finally, based on the first structural parameter information, total mass, total energy, and heat and mass transfer, determine the pressure, vapor region mass, and vapor region enthalpy of the target voltage regulator at the current time point. This application embodiment is based on a voltage regulator model and determines the heat and mass transfer of the target voltage regulator at the current time point based on the vapor-liquid enthalpy and the vapor-liquid heat and mass transfer constitutive equation. Furthermore, based on the first structural parameter information, total mass, total energy, and heat and mass transfer, the pressure, vapor-liquid region mass, and vapor-liquid region enthalpy of the target regulator at the current time point can be accurately calculated. This comprehensively considers heat and mass transfer phenomena within the regulator, thereby improving the calculation accuracy of the regulator model and the accuracy of regulator parameter calculations.
[0064] For ease of understanding, Figure 3 This is a schematic diagram of the voltage regulator model in one embodiment of this application. Figure 3As shown, the pressure regulator model involved in this embodiment includes at least one of the following: a spray pipe 301, a vapor zone 302, a liquid zone 303, a safety valve 304, an electric heater 305, and a oscillation pipe 306. The spray pipe 301 controls the flow rate of the medium in the pressure regulator. When the pressure in the system circuit exceeds a set value, the spray pipe opens, releasing a certain amount of medium to reduce the pressure in the system circuit. When the pressure is lower than the set value, the spray pipe closes, stopping the release of medium. The safety valve 304 is a safety protection device in the pressure regulator. When the pressure in the system circuit exceeds the maximum pressure value set by the safety valve, the safety valve automatically opens, releasing excess medium to protect the system circuit from damage caused by excessive pressure. The electric heater 305 controls the temperature of the medium in the pressure regulator. Through the heating effect of the heater, the temperature of the medium can be increased, thereby increasing the vapor pressure of the medium to achieve the purpose of stabilizing the pressure in the system circuit. The oscillation pipe 306 is the core component of the pressure regulator, used to sense pressure changes in the system circuit. When the pressure in the system loop fluctuates, the oscillation tube generates a corresponding flow rate. Through cooperation with other components, it adjusts the working state of the voltage regulator to maintain a stable pressure in the system loop.

[0116] Of course, the total mass equation of the liquid region can also be expressed as other variations or equivalent formulas of the above formula (7).
[0117] S502. Based on the first structural parameter information, heat transfer and mass transfer, total mass of the liquid zone, and the pressure of the target regulator at the previous time point, determine the enthalpy value of each node in the liquid zone of the target regulator at the current time point.
[0118] Optionally, in the embodiments of this application, the enthalpy values of each node in the liquid region are used to indicate the thermal energy values at different node positions in the liquid region of the target voltage regulator after the liquid region is divided into n equal mass nodes.
[0119] In this embodiment, the electronic device can obtain the enthalpy values of each node in the liquid region at the current time point by substituting the flow rate of the fluctuating pipe, the flow rate of the spray pipe, the flow rate of the safety valve, the external heat source, the heat and mass transfer, the total mass of the liquid region, and the pressure of the target voltage regulator at the previous time point from the first structural parameter information into a preset equation.

[0120] In summary, the electronic equipment can determine the total mass of the liquid zone of the target pressure regulator at the current time point based on the flow rates of the oscillating pipe, spray pipe, safety valve, external heat source, and heat and mass transfer. Furthermore, based on the calculated total mass of the liquid zone, the pressure of the target pressure regulator at the previous time point, the flow rates of the oscillating pipe, spray pipe, safety valve, external heat source, and heat and mass transfer, the electronic equipment determines the enthalpy values of each node in the liquid zone of the target pressure regulator at the current time point. This embodiment of the application determines the total mass of the liquid zone of the target pressure regulator at the current time point based on the heat and mass transfer calculated from the vapor-liquid heat and mass transfer constitutive equation. Furthermore, based on the calculated total mass of the liquid zone, the pressure of the target pressure regulator at the previous time point, and heat and mass transfer, the enthalpy values of each node in the liquid zone can be calculated more accurately, which is beneficial for improving the accuracy of the pressure regulator parameters.

For example... Figure 6 As shown, step S502 includes steps S601 and S602.
[0122] Step S601: Based on the first structural parameter information, heat transfer and mass transfer, and total mass of the liquid zone, determine the inflow and outflow rates of each node in the liquid zone of the target voltage regulator.
[0123] In this embodiment, the electronic device can obtain the total mass of the liquid zone based on the flow rate of the ripple pipe, the flow rate of the spray pipe, the flow rate of the safety valve, and the heat and mass transfer information in the first structural parameter information. Furthermore, the electronic device can determine the mass of each node in the liquid zone based on the total mass of the liquid zone, the first structural parameter information, and the heat and mass transfer information, and calculate the inflow and outflow rates of each node in the liquid zone of the target voltage regulator using the liquid zone mass conservation equation.
[0124] For example, in the embodiments of this application, the inflow rate of any liquid zone node is used to indicate the mass flow rate entering the liquid zone node per unit time; the outflow rate of any liquid zone node in the embodiments of this application is used to indicate the mass flow rate leaving the liquid zone node per unit time.
[0125] For example, the liquid region mass conservation equation involved in the embodiments of this application is used to characterize the change in mass within the liquid region of the target voltage regulator, and can be expressed as the following formula (8):

[0128] Of course, the mass conservation equation of the liquid region can also be expressed as other variations or equivalent formulas of the above formula (8).
[0129] Thus, through the above implementation method, the inflow and outflow rates of each node in the liquid zone of the target voltage regulator are obtained; this flow information is very important for further analysis of the mass distribution, flow characteristics and thermal balance of the liquid zone.
[0130] Step S602: Based on the first structural parameter information, heat and mass transfer, total mass of the liquid zone, pressure at the previous time point, inflow rate, outflow rate, and enthalpy of each node of the liquid zone at the previous time point, determine the enthalpy of each node of the target regulator at the current time point.
[0131] In this embodiment, the electronic device can calculate the enthalpy of each node in the liquid zone at the current time point based on the flow rate of the fluctuating pipe, the flow rate of the spray pipe, the flow rate of the safety valve, the external heat source, the heat and mass transfer, the total mass of the liquid zone, the pressure at the previous time point, the inflow and outflow rates obtained in step S601, and the enthalpy of each node of the liquid zone of the target voltage regulator at the previous time point, using the liquid zone energy conservation equation.
[0132] For example, the liquid region energy conservation equation involved in the embodiments of this application is used to characterize the energy change in the liquid region of the target voltage regulator, and can be expressed as the following formula (9):
[0133] dH l,n / dt=(w r,n +w cs,n +w ci,n +wcw,n )h fs -w fl,n h gs +w sp,l,n h sp,l +w su,l,n h su,l -w sv,l,n h l,n +w in,n h l,n-1 -w out,n h l,n +Q ht,n +Q s,l,n +Q tc,n +V l,n dP / dt (9)
[0134] Among them, w cw,n The wall condensation flow rate at the nth node is expressed in kg / s; h gs The vapor phase saturation enthalpy is expressed in J / kg; h sp,l The enthalpy of liquid spraying is expressed in J / kg; h su,l The flow enthalpy of the liquid-zone fluctuation tube is expressed in J / kg; h l,n h represents the enthalpy of the nth node in the liquid region at the previous time point, in J / kg. l,n-1 Q represents the enthalpy of the (n-1)th node in the liquid region at the previous time point, in J / kg. ht,n Q represents the interfacial heat transfer at node n, expressed in W. s,l,n Q is the external heat source at the nth node of the liquid region, with units of W; tc,n Heat conduction at the nth node, in W; V l,n Let m be the volume of the nth node in the liquid region. 3 P represents the pressure at the previous time point, in Pa; H l,n This represents the total enthalpy of the nth node in the liquid region at the current time point, in J.
[0135] It should be understood that, according to H l,n and M l,n The enthalpy value of the nth node in the liquid region at the current time point can be calculated, for example, by using H l,n With M l,n The enthalpy value of the nth node in the liquid region at the current time point is obtained by calculating the ratio.
[0136] Of course, the energy conservation equation in the liquid region can also be expressed as other variations or equivalent formulas of the above formula (9).
[0137] Thus, through the above implementation method, the electronic device obtains the inflow and outflow rates of each node in the liquid region of the target voltage regulator based on the liquid region mass conservation equation. Furthermore, based on the liquid region energy conservation equation and the inflow and outflow rates of each node in the liquid region, the electronic device can more accurately obtain the enthalpy values of each node in the liquid region of the target voltage regulator at the current time point, comprehensively considering heat and mass transfer phenomena within the voltage regulator, thereby improving the calculation accuracy of the voltage regulator model and the accuracy of voltage regulator parameter calculations.
[0138] based on Figure 4 The embodiment shown, Figure 7 This is a flowchart illustrating a method for determining voltage regulator parameters in another embodiment of this application, as shown below. Figure 7 As shown, based on the above embodiments, this application embodiment describes and explains step S404, which involves determining the pressure, steam zone mass, and steam zone enthalpy of the target voltage regulator at the current time point based on the first structural parameter information, total mass, total energy, and heat and mass transfer. For example... Figure 7 As shown, step S404 may include S701, S702 and S703.
[0139] Step S701: Determine the steam zone mass of the target voltage regulator at the current time point based on the first structural parameter information and heat and mass transfer.

[0156] In this embodiment, the electronic device can determine the pressure and enthalpy of the target voltage regulator at the current time point by performing step-by-step iterative solutions based on the preset control equations, according to the target voltage regulator's steam zone mass, steam zone energy, total energy, and total mass at the current time point.
[0157] In summary, the electronic device can calculate the liquid region mass of the target regulator at the current time point based on the vapor region mass conservation equation. Then, the electronic device substitutes the data obtained from the above solution into the vapor region energy conservation equation to calculate the vapor region energy of the target regulator at the current time point. Further, the electronic device performs step-by-step iterative solutions using preset control equations to determine the pressure and vapor region enthalpy of the target regulator at the current time point.

[0158] based on Figure 7 The embodiment shown, Figure 8 This is a flowchart illustrating a method for determining voltage regulator parameters in another embodiment of this application, as shown below. Figure 8 As shown, based on the above embodiments, this application embodiment describes and explains step S703, which involves determining the pressure and enthalpy of the target voltage regulator at the current time point based on the steam zone mass, steam zone energy, total energy, and total mass of the target voltage regulator at the current time point. For example... Figure 8 As shown, step S703 may include steps S801 and S802.
[0159] Step S801: Determine the enthalpy value of the target regulator in the current time zone based on the current time zone mass, energy, pressure of the target regulator at the previous time zone, and specific volume of the steam zone.
[0160] For example, the vapor zone volume ratio involved in the embodiments of this application can be used to indicate the volume occupied by a unit mass of vapor zone. The vapor zone volume ratio can be expressed as the following formula (13):
[0161]
[0162] Among them, M v V represents the mass of the gas section, expressed in kg. v This refers to the volume of the vapor chamber, in meters (m). 3 ;v v This refers to the specific volume of the vapor zone, in cubic meters (m³). 3 / kg.
[0163] Of course, the specific volume of the vapor zone can also be expressed as other variations or equivalent formulas of the above formula (13).
[0164] In this embodiment of the application, the electronic device can calculate the enthalpy value of the target voltage regulator at the current time point based on the steam zone mass, steam zone energy, pressure of the target voltage regulator at the previous time point, and steam zone specific volume, according to the preset first control equation.
[0165] For example, the first governing equation involved in the embodiments of this application can be expressed as the following formula (14):
[0166] h v =u v +Pv v (14)
[0167] Among them, u v The specific internal energy of the vapor region is expressed in J / kg / h. v This represents the enthalpy value of the vapor region at the current time point.
[0168] Of course, the first governing equation can also be expressed as other variations or equivalent formulas of the above formula (14).
[0169] Optionally, the specific internal energy of the steam zone involved in the embodiments of this application can be used to indicate the energy occupied by a unit mass of steam zone. The specific internal energy of the steam zone can be expressed as the following formula (15):
[0170]
[0171] Among them, M v For the quality of the vehicle area; U v For the energy of the gas field.
[0172] Of course, the specific internal energy of the gas region can also be expressed as other variations or equivalent formulas of the above formula (15).
[0173] S802, based on the total energy, total mass, liquid zone specific volume, liquid zone enthalpy, vapor zone mass, and vapor zone enthalpy of the target regulator at the previous time point, determine the pressure of the target regulator at the current time point.
[0174] For example, the liquid zone specific volume involved in the embodiments of this application can be used to indicate the volume occupied by a unit mass of liquid zone; the liquid zone specific volume can be expressed as the following formula (16):
[0175]
[0176] Among them, v l This refers to the specific volume of the liquid region, in cubic meters (m³). 3 / kg; V l The volume of the liquid region is expressed in cubic meters (m³). 3 .
[0177] Of course, the specific volume of the liquid region can also be expressed as other variations or equivalent formulas of the above formula (16).
[0178] In this embodiment, the electronic device can determine the pressure of the target voltage regulator at the current time point by using a preset second control equation based on the total energy, the liquid specific volume, liquid enthalpy, vapor mass, and vapor enthalpy of the target voltage regulator at the previous time point.
[0179] For example, the second governing equation involved in the embodiments of this application can be expressed as the following formula (17):
[0180] h l =(UM v h v +PV) / (MM v (17)
[0181] Where V is the total volume of the voltage regulator, in meters. 3 h l This represents the enthalpy of the liquid region at the current time point, expressed in J / kg.
[0182] Of course, the specific volume of the liquid region can also be expressed as other variations or equivalent formulas of the above formula (17).
[0183] Optionally, the total volume of the voltage regulator can be expressed as follows (18):
[0184] V = (MM) v )v l +M v v v (18)
[0185] Of course, the total volume can also be expressed as other variations or equivalent formulas of the above formula (18).
[0186] Thus, through the above implementation method, the electronic device can determine the vapor enthalpy value of the target regulator at the current time point based on the preset first control equation. Furthermore, the electronic device substitutes the data obtained from the above solution into the preset second control equation for calculation, thereby accurately obtaining the pressure of the target regulator at the current time point, which helps improve the accuracy of the regulator parameters.
[0187] based on Figure 8 The embodiment shown in this application further describes step S801 of the above embodiment, which involves determining the enthalpy value of the target voltage regulator at the current time point based on the current time point's steam zone mass, steam zone energy, the target voltage regulator's pressure at the previous time point, and the steam zone specific volume. Step S801 may include:
[0188] Based on the current steam zone mass, steam zone energy, the target regulator's pressure at the previous time point, and the steam zone specific volume, iterative processing is performed to obtain the target regulator's steam zone enthalpy value at the current time point. The steam zone enthalpy value at the current time point satisfies the preset iteration termination condition.
[0189] Optionally, in this embodiment, the preset iteration termination condition is that the difference between the iterative value of the vapor region enthalpy at the previous time point and the iterative value of the vapor region enthalpy at the current time point is less than a preset difference (e.g., 10). -4 (etc.)
[0190] In this embodiment, the electronic device can substitute the current vapor zone mass, vapor zone energy, and the target voltage regulator's pressure and vapor zone specific volume at the previous time point into the first control equation, and use a step-by-step iterative method until the vapor zone enthalpy value of the target voltage regulator at the current time point that meets the preset iteration termination condition is obtained.
[0191] Accordingly, the electronic device substitutes the total energy, total mass, liquid zone specific volume, liquid zone enthalpy, vapor zone mass, and vapor zone enthalpy of the target regulator at the previous time point into the second control equation, and uses a step-by-step iterative method until the pressure of the target regulator at the current time point is obtained under the condition of satisfying the preset iteration termination condition.
[0192] For example, suppose the enthalpy of the vapor region at the previous time point is A, and the enthalpy of the vapor region at the current time point is B. If AB < 10 -4 If the iteration termination condition is met, the regulator pressure and vapor zone enthalpy at the new moment are obtained, and the calculation for the next time period begins.
[0193] In summary, the electronic device uses a step-by-step iterative method based on the first and second control equations. When the enthalpy value of the vapor region at the current time point meets the preset iteration termination condition, it is beneficial to accurately obtain the enthalpy value of the voltage regulator's vapor region, thereby improving the accuracy of the voltage regulator parameters.

[0197] For example, the liquid zone specific volume function involved in the embodiments of this application can be expressed as the following formula (19):
[0198] v l =v l (P1,h l (19)
[0199] Where P1 is the pressure at the current time point, in Pa.
[0200] Of course, the liquid volume function can also be expressed as other variations or equivalent formulas of the above formula (19).
[0201] Step S902: Determine the specific volume of the steam region of the target regulator at the current time point based on the enthalpy and pressure of the steam region of the target regulator at the current time point.
[0202] In this embodiment of the application, the electronic device can obtain the vapor zone specific volume of the target voltage regulator at the current time point based on the vapor zone enthalpy and pressure of the target voltage regulator at the current time point and a preset vapor zone specific volume function.
[0203] For example, the specific volume function of the vapor zone involved in the embodiments of this application can be expressed as the following formula (20):
[0204] v v =v v (P1,h v (20)
[0205] Of course, the volume function of the vapor zone can also be expressed as other variations or equivalent formulas of the above formula (20).
[0206] Thus, through the above implementation method, the electronic device, based on the first and second control equations, adopts a step-by-step iterative method, comprehensively considering heat and mass transfer phenomena within the voltage regulator, and can accurately obtain the enthalpy and pressure of the voltage regulator's steam region when the enthalpy value of the steam region at the current time point meets the preset iteration termination condition, thereby improving the accuracy of voltage regulator parameter calculation.
