[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] Various non-limiting implementations of the present application are described in detail below in conjunction with the accompanying drawings.

[0046] Exemplary Methods

[0047] See also Figure 1 , which is a flow chart of a data processing method based on a generator set provided in an embodiment of the present application. In one example, the method can be applied to a data processing system based on a generator set. Figure 2 , which is a schematic diagram of the structure of a data processing system based on a generator set provided in an embodiment of the present application. Figure 2 As shown, the data processing system 200 includes: a data acquisition device 201, a parameter correction device 202 and a first generator set mechanism model 203. Among them:

[0048] The data acquisition device 201 is used to collect the operating data of the generator set, and the parameter correction device 202 is used to receive the operating data collected by the data acquisition device and process the operating data to obtain the processing results; the first generator set mechanism model 203 is used to receive the processing results sent by the parameter correction device 202 and correct the first generator set mechanism model 203.

[0049] For the specific steps performed by the data processing system 200, reference may be made to the description of S101-S103 below, wherein the data acquisition device 201 may perform S101, the parameter correction device 202 may perform S102, and the first generator set mechanism model 203 may perform S103.

[0050] In this embodiment, Figure 1 The method shown may include, for example, the following steps: S101 - S103 .

[0051] S101: Acquire the operating data of the generator set.

[0052] In one example, the operating data of the generator set may be acquired through a data acquisition device, and the operating data of the generator set may include at least one parameter during the operation of the generator set.

[0053] In one example, the data acquisition device may be a real-time supervisory information system at plant level (SIS) of a power plant.

[0054] In one example, the parameters during the operation of the generator set include but are not limited to the following parameters: main steam flow, main steam pressure, main steam temperature, feed water flow, electric power, superheater and reheater water spray volume, superheater outlet temperature and pressure, high-pressure cylinder first stage pressure, reheater outlet temperature and pressure, condenser pressure, fuel quantity, total air volume, exhaust temperature, etc.

[0055] S102: Obtaining a correction value of a first operating parameter of a first device in the generator set according to the operating data of the generator set.

[0056] After the operating data of the generator set is acquired, the operating data of the generator set may be processed to obtain a corrected value of a first operating parameter of a first device in the generator set.

[0057] Regarding the first device, it can be any device in a generator set, and the present application embodiment does not make any specific limitation. In one example, the first device can be a steam turbine, and in another example, the first device can be a furnace.

[0058] The first operating parameter may be any operating parameter of the first device during operation. In one example, when the first device is a steam turbine, the first operating parameter may be the efficiency of the steam turbine; in another example, when the first device is a furnace, the first operating parameter may be the heat transfer coefficient of the furnace.

[0059] In one example, when S102 is implemented, the operating data of the generator set may be analyzed according to a specific algorithm to obtain a corrected value of the first operating parameter.

[0060] In another example, when S102 is specifically implemented, the early warning model can be used to obtain the corrected value of the first operating parameter. In this case, the aforementioned parameter correction device 202 can be the early warning model mentioned here. In an embodiment of the present application, the early warning model can output the corrected value of the operating parameter of at least one device included in the thermal power unit according to the operating parameters of the generator set in the early warning model. In an embodiment of the present application, the operating data of the generator set obtained in S101 can be input into the early warning model, and the early warning model can output the corrected value of the first operating parameter.

[0061] In an embodiment of the present application, the early warning model may be pre-trained. In a specific example, the early warning model may be trained according to training operating parameters. As a specific example, the training operating parameters may correspond to operating parameters when various operating indicators of the generator set (such as rapid load change capability) meet expectations.

[0062] In one example, the training operation data in the embodiment of the present application may be historical operation data of the generator set.

[0063] In another example, considering that the actual operating data of the generator set is limited during the generator set planning stage. Therefore, the training operating data may also be the operating data output by the third generator set mechanism model. In one example, the third generator set mechanism model may be an initial model initially constructed based on the operating mechanism of the generator set. In one example, the initial model may be the first generator set mechanism model mentioned above, or it may not be the first generator set mechanism model. When the initial model is not the first generator set mechanism model, the first generator set mechanism model may be a model obtained after modifying the initial generator set mechanism model.

[0064] S103: According to the correction value of the first operating parameter, the first generator set mechanism model is corrected to obtain a second generator set mechanism model, wherein the first generator set mechanism model and the second generator set mechanism model are simulation models of the generator set.

[0065] After obtaining the corrected value of the first operating parameter, the first generator set mechanism model can be corrected according to the corrected value of the first operating parameter to obtain the second generator set mechanism model. In one example, the first operating parameter in the first generator set mechanism model can be modified according to the corrected value to obtain the second generator set mechanism model.

[0066] In the embodiment of the present application, the first generator set mechanism model and the second generator set mechanism model are both simulation models of the generator set, and the first generator set mechanism model and the second generator set mechanism model can reflect the operating mechanism of the generator set.

[0067] In one example, the first generator set mechanism model can be an initial model constructed based on the operating mechanism of the generator set, or a model updated based on the initial model, which is not specifically limited in the embodiments of the present application. The method of updating the initial model is similar to the method of updating the first generator set mechanism model, and will not be repeated here.

[0068] It can be seen that by utilizing the solution of the embodiment of the present application, the simulation model of the generator set can be updated based on the operating data of the generator set, so that the updated second generator set mechanism model is more accurate, and correspondingly, the operating parameters of the generator set determined based on the second generator set mechanism model will also be more reasonable, thereby making the operation process of the generator set more in line with expectations.

[0069] Next, the relationship between the generator set model and the generator set is introduced.

[0070] See also Figure 3 , Figure 3 A schematic diagram of the structure of another data processing system based on a generator set provided in an embodiment of the present application. Figure 3 As shown:

[0071] The first generator set mechanism model 203 may output operating parameters to the first control system 301. After receiving the operating parameters, the first control system 301 may obtain a control amount based on the operating parameters and send the control amount to the second control system 302. After receiving the control amount, the second control system 302 may control the operation of the generator set based on the control amount.

[0072] Regarding the specific implementation of the first control system 301 obtaining the control amount according to the received operating parameters, a traditional control amount determination method can be adopted, and the embodiment of the present application does not make any specific limitation.

[0073] In addition, the specific implementation method of the second control system 302 controlling the operation of the generator set based on the control amount may also adopt a traditional control method, which is not specifically limited in the embodiment of the present application.

[0074] In one example, the first control system may be a virtual control system constructed based on a virtual data processing unit (DPU), and the second control system may be a field control system in the same area as the generator set.

[0075] In one example, the first control system and the first generator set mechanism model may communicate with each other via an Object Linking and Embedding for Process Control (OPC) protocol.

[0076] After the first generator set mechanism model is corrected to the second generator set mechanism model, the second generator set mechanism model can output operating parameters to the first control system 301, so that the first control system 301 obtains the control quantity based on the operating parameters, and sends the control quantity to the second control system 302, and the second control system 302 is used to control the operation of the generator set based on the control quantity.

[0077] In one example, if Figure 3 As shown, the first generator set mechanism model 203 and the data acquisition device 201 can also be connected to the three-dimensional visualization system 303.

[0078] As an example, the three-dimensional visualization system 303 can truly reflect the position, size, shape and other information of each device and system in the power plant. The status and display effect of the equipment are driven by data, for example, three-dimensional dynamic special effects display can be performed according to given data.

[0079] In one example, the three-dimensional visualization system 303 can display the operating data collected by the acquisition device 201. This enables visual status monitoring. In addition, the three-dimensional visualization system can also enable virtual characters to roam the entire plant within the simulation range. It includes modules such as power plant cognition, main system principles, main equipment principles, equipment assembly, knowledge learning and assessment. In the virtual scene, operations such as search positioning, automatic roaming, fixed-point roaming, flight mode, and equipment information viewing can be performed.

[0080] In another example, when the first generator mechanism model 203 is connected to the three-dimensional visualization system 303, the user can operate valves, pumps and other equipment in the display page of the three-dimensional visualization system 303, and can operate some local equipment in the three-dimensional scene. By clicking on the equipment in the interface, the scene of the three-dimensional visualization system can be positioned near the corresponding equipment.
