Description

Technical Field

[0001] This invention relates to the technical field of water vapor thermal energy conversion monitoring, and in particular to a method and device for monitoring the process of water vapor thermal energy conversion. Background Technology

[0002] A boiler is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. A boiler consists of two parts: the boiler and the furnace. The hot water or steam produced in the boiler can directly provide the thermal energy needed for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. Boilers are widely used in railway stations, ships, locomotives and industrial and mining enterprises. The boiler steam production process has typical nonlinear and large time delay characteristics.

[0003] The application of advanced control algorithms in modern industry is of positive significance for improving system control quality, saving energy, and increasing economic efficiency. At the same time, variable load is also a common problem in industry. However, the phenomenon of resource waste and loss of economic benefits due to untimely system response is also very common. Designing a coordination system in the whole process of water, steam and heat energy to improve the system response speed plays an important role in improving the response capability of complex large-scale systems.

[0004] Water-steam thermal energy conversion is a complex, multi-variable controlled object with uncertainties. Although the boiler and evaporator each have their own regulation systems, considering the characteristics of joint operation, they must maintain a coordinated operating mode so that the entire water-steam thermal energy system can adapt to the system's variable load as soon as possible, while ensuring the system's safe and stable operation. Therefore, monitoring the water-steam thermal energy conversion process is of paramount importance. Summary of the Invention

[0033] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0034] Example 1

[0035] Reference Figure 1 The first embodiment of the present invention provides a method for monitoring the process of water vapor-thermal energy conversion, comprising:

[0036] S1: A general model of the conversion resources in the entire water vapor-thermal energy process system is performed to obtain a preliminary monitoring model. It should be noted that the conversion resources include:

[0037] Evaporator load, main steam pressure, control valve opening, concentrated oil concentration, air supply volume, water supply volume, and main steam flow rate.

[0038] Furthermore, the general modeling provides a universal state-space model for the entire water vapor-thermal energy system operation, including:

[0039]

[0040]

[0041]

[0042] Where x is a state variable common to the entire water vapor thermal energy system, x min x is the minimum value of the state variable that is universally applicable to the entire process of water vapor thermal energy system operation. max Let q be the maximum value of the state variables common to the entire water vapor thermal energy system, q be the water vapor thermal energy conversion state coefficient indicating how quickly it maintains its current state, and k be the load energy consumption p. f The contribution coefficient to the state variable, where n is the node number of the water vapor-thermal energy conversion and t is the time.

[0043] Specifically, the initial monitoring model is obtained and trained, including:

[0044] Initialize the population and set its initial velocity;

[0045] Based on the load aggregator's initial strategy, the boiler, evaporator, and monitoring system each output decision factors according to their own utility functions and transmit them to the load aggregator.

[0046] After receiving the decision factors, the load aggregator makes a decision and transmits it to its followers;

[0047] The follower determines whether the initial monitoring model has converged based on the decision. If it has converged, it exits the loop and outputs the model results.

[0048] Otherwise, update the particle position until the convergence criterion is met, then exit the loop and output the model result.

[0049] S2: Solve the preliminary monitoring model using the binary approach based on the Fibonacci sequence to establish coordinated management of water vapor-thermal energy conversion. This step requires clarification regarding the binary approach solution, which includes:

[0050] Transform the state-space model into a space matrix;

[0051] Add the Fibonacci sequence to calculate the Nth power of the spatial matrix;

[0052] By using the binary concept, N can be decomposed into binary numbers for faster calculation;

[0053] The final solution obtained is the final value of the space matrix, which is the solution of the general model;

[0054] The solution is the optimal golden ratio for the operating system during water vapor-thermal energy conversion. Partial running code is as follows:

[0055]

[0056]

[0057] S3: Introducing synergistic factors into the entire water-steam thermal energy process system, and coordinating with water-steam thermal energy conversion management to monitor and manage the real-time boiler water-steam thermal energy conversion system. It should also be noted that the introduced synergistic factors include:

[0058] Historical operational data of the entire water vapor thermal energy system were collected and preprocessed to form a sample dataset.

[0059] The boiler's variable inertia parameters and the evaporator's variable inertia parameters are obtained by performing parameter calculations on the sample dataset using the least squares machine.

[0060] The boiler's changing inertial parameters and the evaporator's changing inertial parameters are balanced based on the recursive equation, and the cooperative weights are output.

[0061] The collaborative weight is the collaborative factor;

[0062] Furthermore, monitoring and management include:

[0063] Add synergistic factors to the entire process system of water vapor thermal energy;

[0064] Read the solution of the general model for the operation of the entire water vapor thermal energy system;

[0065] The synergistic factor and solution are set as the threshold value for monitoring water vapor-thermal energy conversion. If the threshold value is exceeded, an anomaly is identified.

[0066] Ideally, the water-steam thermal energy conversion is a complex, multi-variable controlled object with uncertainties. Although the boiler and evaporator each have their own regulation systems, considering the characteristics of joint operation, they must maintain a coordinated operating mode so that the entire water-steam thermal energy system can adapt to the system's variable load as soon as possible, while ensuring the safe and stable operation of the system. Therefore, monitoring the water-steam thermal energy conversion process is of paramount importance.

[0067] Preferably, in order to better verify and illustrate the technical effects of the method of the present invention, this embodiment compares the traditional water vapor heat energy conversion control method with the method of the present invention through a comparative experiment, and compares the experimental results with scientific demonstration methods to illustrate the real technical effects of the method of the present invention.

[0068] The first-order pure control model provided in the traditional water vapor-thermal energy conversion control method is programmed to obtain the first program execution body. Then, the preliminary monitoring model, coordination factor and solution provided by the method of this invention are programmed to obtain the second program execution body. The first program execution body and the second program execution body are imported into MATLAB for simulation study.

[0069] Adjust the controller parameters to obtain the optimal value, input the processed water vapor heat energy conversion related parameters, set the monitoring parameters to Tr=20, H=2, give a step 10 to observe the system response curve, judge the output curve, and obtain the final monitoring test results.

[0070] Reference Figure 2 It can be clearly seen that, for monitoring the water vapor-thermal energy conversion process, the method of the present invention is closer to the characteristics of the monitored object than the traditional method, and the response effect is better. That is, the monitoring effect of the method of the present invention is significantly improved and the response process is smooth.
