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 are within the scope of protection of this application.

[0057] In one embodiment, as shown in FIG2 , a current signal delay compensation method is provided. The method is described by taking the computer device in FIG1 as an example, and includes the following steps:

[0058] S201, in the process of monitoring the current of the rhodium reactor through the rhodium self-powered detector SPND, obtaining a real-time current signal sampled by the SPND at a current sampling moment.

[0059] The real-time current signal is a current signal generated by the decay process of rhodium elements in the rhodium reactor.

[0060] Specifically, because the decay of rhodium generates a current signal, the magnitude of which is proportional to the neutron flux at its location, which in turn is closely related to the power and status of the nuclear reactor. Therefore, a rhodium self-powered detector (SPND) is typically used to detect the current signal at various locations. Based on this current signal, the power and status of the nuclear reactor can be determined. While the rhodium self-powered detector (SPND) outputs a real-time current signal at the current sampling moment, it should be noted that this real-time current signal is delayed and does not reflect the power and status of the nuclear reactor at the current sampling moment.

[0061] S202 , performing delay compensation processing on the real-time current signal according to the delay compensation parameter to obtain a target current signal.

[0062] Among them, the delay compensation parameter is related to the real-time current signal, the historical current signal collected by SPND at each historical sampling moment before the current sampling moment, and the sampling period. The delay compensation parameter is used to characterize the current attenuation caused by the decay of the rhodium element in the rhodium reactor before the current sampling moment; the target current signal is the real-time circuit signal after delay compensation processing, and the target current signal can accurately reflect the power and status of the nuclear reactor at the current sampling moment.

[0063] Specifically, a low-pass filter can be used to filter out high-frequency noise in the real-time current signal, and then the delay compensation parameter and the real-time current signal are substituted into a preset compensation calculation formula (for example, Formula 6 in the embodiment below) to perform delay compensation calculation, and the calculation result is the target current signal.

[0064] Optionally, when performing delay compensation processing, it can also be determined whether the current sampling moment is the initial sampling moment; if the current sampling moment is the initial sampling moment, a first delay compensation parameter is obtained, and the real-time current signal is delayed compensated using the first delay compensation parameter to obtain a target current signal; if the current sampling moment is not the initial sampling moment, the historical current signal and sampling period collected by SPND at each historical sampling moment are obtained; based on the real-time current signal, each historical current signal and the sampling period, a second delay compensation parameter is calculated; and the real-time current signal is delayed compensated using the second delay compensation parameter to obtain a target current signal.

[0065] The first delay compensation parameter is a delay compensation parameter calculated in a historical delay compensation process, and the second delay compensation parameter is a delay compensation parameter calculated in a current delay compensation process.

[0066] Specifically, when performing delay compensation processing, since the calculation of the delay compensation parameter involves a historical current signal, if the current sampling moment is the initial sampling moment, no historical current signal exists. Therefore, it is necessary to obtain the first delay compensation parameter calculated during the historical delay compensation process from the storage system of the computer device, and substitute the first delay compensation parameter and the real-time current signal into a preset formula (for example, Formula 6 in the embodiment below), and the result obtained is the target current signal; if the current sampling moment is not the initial sampling moment, there is a historical current signal. At this time, the historical current signal and the sampling period can be obtained from the storage system of the computer device, and the real-time current signal, each historical current signal, and the sampling period are substituted into a preset calculation formula (for example, Formulas 11-12 in the embodiment below) to calculate a second delay compensation parameter. Finally, the second delay compensation parameter and the real-time current signal are substituted into the preset formula (for example, Formula 6 in the embodiment below), and the result obtained is the target current signal.

[0067] Optionally, the process of calculating the second delay compensation parameter can be: substituting the sampling period into a preset calculation formula (such as formulas 9-12 in the embodiments below) to calculate the first compensation coefficient and the second compensation coefficient; calculating the first decay compensation parameter based on the real-time current signal, each historical current signal and the first compensation coefficient, and calculating the second decay compensation parameter based on the real-time current signal, each historical current signal and the second compensation coefficient; summing the first decay compensation parameter and the second decay compensation parameter to obtain the second delay compensation parameter.

[0068] Among them, the first decay compensation parameter is the current attenuation caused by the rhodium element in the rhodium reactor decaying into activated nuclei before the current sampling time; the second decay compensation parameter is the current attenuation caused by the rhodium element in the rhodium reactor decaying into an isomeric state before the current sampling time.

[0069] For example, as shown in FIG3 , FIG3 is a schematic diagram of a nuclear reaction during the decay of rhodium in one embodiment. After neutron irradiation, 92% of them become activated nuclei The remaining 8% becomes isomers After a half-life of 4.3 minutes, it is converted to Nuclide After 42 seconds of β decay, it transitions to a stable element By analyzing the physical properties of rhodium metal, it can be found that the change in neutron flux caused by power change and the change in the output current of the rhodium detector satisfy a fixed numerical relationship. Through numerical research, it is found that the change in neutron flux and the current signal output by the SPND are related to each other as shown in formulas (1)-(3): I(t)=cn(t)+λ1m1(t) (3)

[0070] Among them, m1(t) and m2(t) represent 104 Rh and 104m The amount of charge directly caused by Rh; n(t) represents the detector current signal of SPND; λ1 and λ2 represent 104 Rh and 104m Rh is the decay constant; c is the instantaneous response share of the detector current signal; a1 and a2 are 104 Rh and 104m The current share caused by Rh; I(t) represents the current signal output by SPND.

[0071] Performing Laplace transform on the above formulas (1)-(3) yields the following formula (4):

[0072] Where I(s) is the current signal, n(s) is the neutron flux, is a fixed parameter.

[0073] Due to the fixed parameters is a fixed value, that is, there is a fixed numerical relationship between the current signal and the neutron flux. Simplifying the above formula (4), we get the following formula (5):

[0074] in, A=(a-λ1)·(a-λ2) / (ba); B=(b-λ1)·(b-λ2) / (ab);

[0075] A, B, a, and b are all parameters, I(s) is the current signal, n(s) is the neutron flux, and P is the nuclear reactor power.

[0076] Assuming the sampling period is T, perform inverse Laplace transform on the above formula (5) to obtain the following formulas (6)-(12): P 补偿 (k)=S·[I(k)+x1(k)+x2(k)] (6) x1(k)=M1*I(k)+M2*x1(k-1) (7); x2(k)=M3*I(k)+M4*x2(k-1) (8); M1=A·T / (a·T+1) (9); (10); M3=B·T / (b·T+1) (11); M4=1 / (b·T+1) (12);

[0077] Among them, I(k) is the real-time current signal at time k, Pcompensation(k) is the target current signal at time k, x1(k) is the first decay compensation parameter, x2(k) is the second decay compensation parameter, S is the adjusted parameter, M1 and M2 are the first compensation coefficients, M3 and M4 are the second compensation coefficients; it should be noted that when k=1, x1(k)+x2(k) is the first delay compensation parameter, when k>1, x1(k)+x2(k) is the second delay compensation parameter, T is the sampling period, x1(k-1) and x2(k-1) are historical current signals, and A, B, a, and b are all parameters.

[0078] That is, when the current sampling moment is the initial sampling moment, the first delay compensation parameter x1(k)+x2(k) and parameter S are obtained from the computer's storage system, and the first delay compensation parameter, parameter S and real-time current signal I(k) are substituted into the above formula (6) to calculate the target current signal.

[0079] When the current sampling moment is not the initial sampling moment, the historical current signals x1(k-1) and x2(k-1) collected by SPND at each historical sampling moment and the sampling period T are obtained, and the sampling period T is substituted into the above formulas (9)-(12) to calculate the first compensation coefficients M1 and M2 and the second compensation coefficients M3 and M4; the real-time current signal I(k), each historical current signal x1(k-1) and the first compensation coefficients M1 and M2 are substituted into the above formula (7) to calculate the first decay compensation parameter x1( k); the real-time current signal I(k), each historical current signal x1(k-2) and the first compensation coefficients M3 and M4 are substituted into the above formula (8) to calculate the second decay compensation parameter x2(k); the sum x1(k)+x2(k) of the first decay compensation parameter x1(k) and the second decay compensation parameter x2(k) is used as the second delay compensation parameter; the second delay compensation parameter x1(k)+x2(k), the parameter S and the real-time current signal I(k) are substituted into the above formula (6) to calculate the target current signal.

[0080] In the above-described embodiment, during the current monitoring of the rhodium reactor using a rhodium self-powered detector (SPND), the real-time current signal sampled by the SPND at the current sampling moment is first acquired. Then, based on the delay compensation parameters, delay compensation is performed on the real-time current signal generated by the decay of the rhodium element in the rhodium reactor to obtain the target current signal. Because this delay compensation process is a software-based approach, compared to traditional hardware-based delay compensation methods, it not only reduces costs but also allows for delay compensation of the current signal at any time, significantly increasing the flexibility of delay compensation.

[0081] In the current signal delay compensation method in the above embodiment, the delay compensation parameter is manually set, and the delay compensation parameter is a key factor in determining whether the target current signal is accurate. Therefore, in this embodiment, as shown in FIG4 , a process for verifying the accuracy of the delay compensation parameter is described. The specific method includes:

[0082] S401 , obtaining a real current signal corresponding to a real-time current signal output by the SPND at a preset time.

[0083] The preset moment is located after the current sampling moment in terms of time sequence, and the real current signal is a current signal that can accurately reflect the state and power of the nuclear reactor.

[0084] Specifically, since the current signal output by SPND has a delay, that is, after the preset time, SPND will output the real current signal corresponding to the real-time current signal, that is, after the preset time, the real current signal corresponding to the real-time current signal output by SPND is obtained.

[0085] S402 , performing a signal value comparison between the actual current signal and the target current signal to obtain a comparison result, and verifying the accuracy of the delay compensation parameter based on the comparison result.

[0086] Specifically, the loss rate between the real current signal and the target current signal can be calculated based on the signal values ​​of the real current signal and the target current signal. If the loss rate is less than or equal to the loss rate threshold, it proves that the delay compensation parameter is highly accurate and does not need to be adjusted; if the loss rate is greater than the loss rate threshold, it proves that the delay compensation parameter is less accurate and needs to be adjusted. After adjusting the delay compensation parameter, the operation of calculating the loss value is re-executed until the loss value is less than or equal to the loss rate threshold.

[0087] For example, as shown in Figure 5, Figure 5 shows the signal numerical relationship between the real-time current signal, the target current signal and the true current signal. It can be seen from the picture that the waveforms of the target current signal and the true current signal almost coincide, that is, the target current signal in this application can accurately reflect the power and status of the nuclear reactor.

[0088] In the above embodiment, the real current signal corresponding to the real-time current signal output by the SPND is compared with the target current signal obtained after the delay compensation processing, so as to verify the accuracy of the delay compensation parameters, which largely ensures the accuracy of the delay compensation parameters and further ensures the accuracy of the target current signal.

[0089] In order to more comprehensively demonstrate this solution, this embodiment provides an optional method for current signal delay compensation, as shown in FIG6 :

[0090] S601, in the process of monitoring the current of the rhodium reactor through the rhodium self-powered detector SPND, obtaining the real-time current signal sampled by the SPND at the current sampling moment.

[0092] S603: If the current sampling moment is the initial sampling moment, obtain a first delay compensation parameter, and use the first delay compensation parameter to perform delay compensation processing on the real-time current signal to obtain a target current signal.

[0098] S608 , performing delay compensation processing on the real-time current signal using the second delay compensation parameter to obtain a target current signal.

[0099] Among them, the first decay compensation parameter is the current attenuation caused by the rhodium element in the rhodium reactor decaying into activated nuclei before the current sampling time; the second decay compensation parameter is the current attenuation caused by the rhodium element in the rhodium reactor decaying into an isomeric state before the current sampling time.

[0100] S609 , obtaining a real current signal corresponding to the real-time current signal output by the SPND at a preset time.

[0101] The preset time is located after the current sampling time in terms of time sequence.

[0102] S610 , performing a signal value comparison between the actual current signal and the target current signal to obtain a comparison result, and verifying the accuracy of the delay compensation parameter based on the comparison result.
