Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
With the continuous development of the nuclear power field, in order to ensure the safe operation of a nuclear reactor, an off-pile detection device is required to detect the nuclear power of the nuclear reactor and convert the nuclear power into thermal power for display.
Currently, nuclear power of a nuclear reactor is generally determined by a fixed nuclear power calculation formula and nuclear reactor operating parameters. However, in a high power operating state of the nuclear reactor (e.g., the nuclear power and the thermal power are greater than the first power, which is typically 30% of the rated power), it is understood that the first power may be adaptively adjusted according to the configuration of the nuclear reactor, where the rated power refers to the maximum power that the nuclear reactor can operate at, and is used to monitor whether the nuclear reactor is overloaded. Referring to fig. 1A, in which the horizontal axis is the thermal power PTH, the vertical axis is the nuclear power PR, and the RPN is the off-pile detection device, it is known from the coordinate point (1,1.26) that when the thermal power reaches the rated power, the nuclear power has reached 126% of the rated power, that is, the nuclear power needs to reach 126% of the rated power to be converted into the thermal power equal to the rated power. At this time, since there is a large deviation between the thermal power and the nuclear power, the reactor is likely to jump directly, and thus it is known that the nuclear power and the thermal power have a large difference in the high-power operation state of the nuclear reactor, and the safety of the nuclear power operation is reduced.
Based on this, in one embodiment, as shown in fig. 1B, there is provided a nuclear power determining method of a nuclear reactor, which is exemplified as an application of the method to an off-stack detection apparatus, including the steps of:
s101, determining the initial nuclear power of the nuclear reactor according to the actual running current of the nuclear reactor and the initial power model of the current wheel.
Wherein the actual operating current refers to the current in the reactor when the reactor is operating, and may include an upper operating current and a lower operating current; the initial power model of the round refers to a trained model, which can be but is not limited to a decision tree model, a random forest model, a support vector machine model, a neural network model, a model degree lifting decision tree model and the like, and is used for determining the nuclear power of the reactor during the running in the round according to the actual running current; the initial core power refers to the core power output by the initial power model of the present round.
Alternatively, the off-stack detection device may directly obtain the actual operating current of the nuclear reactor through a measurement channel connected to the nuclear reactor; and then, the actual running current is directly input into a trained primary initial power model, and the primary initial power model determines the initial nuclear power of the nuclear reactor according to the actual running current and model parameters.
And S102, when the initial nuclear power is larger than the nuclear power threshold, adjusting the initial power model of the present round according to the conversion relation between the nuclear power and the thermal power corresponding to the nuclear reactor, and obtaining the target power model of the present round of the nuclear reactor.
The core power threshold is a numerical value for measuring whether the initial core power can be directly used as the target core power; the round of target power model refers to a neural network model obtained after the round of initial power model is adjusted.
It is understood that the nuclear power of the nuclear reactor core varies greatly in the power up phase. Therefore, in order to ensure the accuracy of the determination of the nuclear power, the initial power model of the present round needs to be adjusted according to the conversion relationship between the nuclear power and the thermal power corresponding to the nuclear reactor, so that the nuclear power output by the target power model of the present round after adjustment is more accurate.
Optionally, in order to more accurately measure whether the nuclear reactor is in a high power stage, the nuclear power threshold may be determined according to a corresponding curve of nuclear power and thermal power of the nuclear reactor in a historical turn. For example, 30% of rated power may be used as the core power threshold.
Further, the initial nuclear power and the nuclear power threshold value can be compared, and under the condition that the initial nuclear power is larger than the nuclear power threshold value, the initial power model of the present round can be trained based on the conversion relation between the nuclear power and the thermal power corresponding to the nuclear reactor, so that the target power model of the present round of the nuclear reactor is obtained.
Accordingly, in the case where the initial nuclear power is less than or equal to the nuclear power threshold, the initial nuclear power is taken as a target nuclear power of the nuclear reactor.
It will be appreciated that since the change in power distribution is small in the low power phase of the nuclear reactor, the initial nuclear power may be directly taken as the target nuclear power of the nuclear reactor.
S103, determining the target nuclear power of the nuclear reactor according to the current round target power model and the actual running current.
Alternatively, after the current round target power model is determined, the actual operating current may be directly input into the current round target power model to determine the target nuclear power of the nuclear reactor.
According to the nuclear power determining method of the nuclear reactor, the initial nuclear power of the nuclear reactor is determined according to the actual running current of the nuclear reactor and the initial power model of the current wheel, and under the condition that the initial nuclear power is larger than a nuclear power threshold value, the initial power model of the current wheel is adjusted according to the conversion relation between the corresponding nuclear power and the thermal power of the nuclear reactor to obtain the target power model of the current wheel of the nuclear reactor, and then the target nuclear power of the nuclear reactor is determined according to the target power model of the current wheel and the actual running current. Compared with the prior art, the nuclear power of the nuclear reactor is determined by adopting a fixed nuclear power calculation formula, the method is adopted, and under the condition that the initial nuclear power is larger than the nuclear power threshold value, the initial power model of the current round is adjusted based on the conversion relation, so that the target power model of the current round is more accurate, the accuracy of the target nuclear power of the nuclear reactor is improved, and the stable operation of the nuclear reactor is further ensured.
In order to ensure the accuracy of the initial power model of the present round, before determining the initial nuclear power of the nuclear reactor, in this embodiment, an alternative manner of determining the initial power model of the present round is provided, as shown in fig. 2, and specifically includes the following steps:
s201, obtaining standard operation current of the nuclear reactor when the nuclear reactor operates at rated power.
The standard operating current refers to the current of the nuclear reactor in normal operation under rated power.
It will be appreciated that in order to ensure the accuracy of the standard operating current, the average value of the theoretical operating currents of the components of the nuclear reactor when operating at rated power may be taken as the standard operating current.
S202, taking the ratio between the standard operation current and the historical operation current as a first adjustment parameter.
Wherein, the historical operating current refers to the current of the nuclear reactor in the previous round when the nuclear reactor normally operates under rated power; the first tuning parameter refers to a proportional value for tuning the model parameters.
Optionally, after determining the standard operating current, the historical operating current of the previous round of operation of the nuclear reactor at the rated power may be divided by the standard operating current, and the first adjustment parameter may be calculated.
And S203, carrying out parameter adjustment on a previous round of target power model of the nuclear reactor according to the first adjustment parameters to obtain a current round of initial power model of the nuclear reactor.
Optionally, after determining the first adjustment parameter, parameters in a previous round of target power model of the nuclear reactor may be adjusted based on the first adjustment parameter to obtain a current round of initial power model of the nuclear reactor. For example, the product between the first tuning parameter and the model parameter of the previous round of the target power model of the nuclear reactor may be taken as the model parameter of the current round of the initial power model of the nuclear reactor.
Alternatively, the product between the first tuning parameter and the model parameter of the previous round of the target power model of the nuclear reactor may be referred to as the model parameter of the current round of the initial power model of the nuclear reactor by referring to the following equations (1) and (2). Wherein, K U refers to the upper matching coefficient between the nuclear reactor operating current and the nuclear reactor nuclear power in the power model, and K L refers to the lower matching coefficient between the nuclear reactor operating current and the nuclear reactor nuclear power in the power model; k U (n+1) and K L (n+1) refer to model parameters of the initial power model of the present round (n+1 round); k U (n) and K L (n) refer to model parameters of the last round (nth round) of the target power model; i n refers to the historical operating current, I n+1 refers to the standard operating current, and further, I n/In+1 refers to the first tuning parameter.

In this embodiment, parameter adjustment is performed on a previous round of target power model of the nuclear reactor according to the first adjustment parameter to obtain a current round of initial power model of the nuclear reactor, so that accuracy of the current round of initial power model can be ensured.
In order to ensure the accuracy of the target power model of the present wheel, in this embodiment, an alternative way of determining the target power model of the present wheel is provided, as shown in fig. 3, and specifically includes the following steps:
s301, determining a second adjusting parameter according to the conversion relation between the nuclear power and the thermal power corresponding to the nuclear reactor.
The conversion relation is represented by a unitary quadratic function; the adjustment coefficients are determined from the function coefficients of the unitary quadratic function.
Alternatively, since the conversion relationship can be characterized by a unitary quadratic function, i.e., the conversion relationship can be assumed to beWherein a and b are the function coefficients of a unitary quadratic function; x represents thermal power; y represents the target core power; therefore, the second tuning parameter m needs to be met/>。
Further, when the nuclear reactor is operated at rated power, both the nuclear power and the thermal power are 1 in the conversion relationship, i.eConversion can obtain/>。
S302, adjusting model parameters of the initial power model of the current round by adopting second adjusting parameters to obtain the target power model of the current round of the nuclear reactor.
Alternatively, the model parameters of the current round target power model may be determined according to the second adjustment parameters and the model parameters of the current round initial power model with reference to the following equations (3) and (4). Wherein, K U '(n+1) and K L' (n+1) refer to model parameters of the current round of target power model.

（4）
Further, the current round target power model of the nuclear reactor can be determined according to model parameters of the current round target power model.
In this embodiment, the second adjustment parameter is adopted to adjust the model parameter of the primary power model to obtain the primary target power model of the nuclear reactor, so that the accuracy of the primary target power model can be ensured.

With reference to fig. 4, the specific implementation procedure is as follows:
