[0035] Figure 1 It is a schematic flowchart of a method for regulating a generator set provided in an embodiment of the present application.
[0036] As Figure 1 shown, the method for regulating the generator set proposed in this embodiment specifically includes the following steps:
[0037] S101. Construct a thermal system model of the generator set based on the heat balance diagram of the generator set.
[0038] In the embodiments of the present application, the heat balance diagram is an image of the heat balance data of the pre-provided generator set, and the thermal system model refers to a model that simulates the conditions of the generator set under different electrical loads and heat loads under the design conditions. As can be understood by those skilled in the art, the thermal system model of the generator set can be constructed through the heat balance diagram of the generator set for subsequent processing. Optionally, the generator set can be a steam turbine generator set, and there can be at least two generator sets. In the present application, two steam turbine generator sets are taken as an example for description, which does not constitute a limitation on the type and quantity of the generator sets. For example, Figure 2 is a schematic diagram of a typical generator set, such as Figure 2 shown, there are two steam turbine generator sets. 1 is the No. 1 unit, 2 is the No. 2 unit, 3 is the high-voltage auxiliary transformer, 4 is the heat supply main station, and 5 is the user. Among them, the rated loads of the No. 1 unit and the No. 2 unit are 200 MW (megawatts).
[0039] S102. Obtain the actual operating parameters of the generator set according to the thermal system model.
[0040] In the embodiments of the present application, the actual operating parameters refer to the actual power generation capacity, actual heat supply capacity, and actual economic indicators of the generator set. The actual operating parameters of the generator set are obtained according to the thermal system model of the generator set constructed in step S101 for subsequent processing.
[0041] It should be noted that the theoretical operating parameters of the generator set can be obtained through simulation by the constructed thermal system model. For example, as mentioned in the above example, the theoretical operating parameters of the No. 1 unit and the No. 2 unit under different conditions (such as the heat rate acceptance condition) can be simulated through the thermal system model. The condition values of 60%, 80%, and 100% are respectively selected for simulation, and the corresponding theoretical parameters can be obtained. Figure 3 is the theoretical operating parameter diagram of the generator set under different conditions. Specifically, it can be as Figure 3 shown, and the theoretical operating parameter diagrams of the No. 1 unit and the No. 2 unit under different heat rate acceptance conditions can be obtained.
[0042] S103. Obtain the adjustment parameters of the generator set according to the actual operating parameters.
[0043] In the embodiments of the present application, the adjustment parameters are the parameters based on which the generator set is adjusted. The adjustment parameters of the generator set are obtained according to the actual operating parameters obtained in step S102.
[0044] S104. Adjust the generator set according to the adjustment parameters.
[0045] In the embodiments of the present application, the generator set is adjusted according to the adjustment parameters of the generator set obtained in step S103.
[0046] The adjustment method of the generator set provided by the present application constructs a thermodynamic system model of the generator set based on the heat balance diagram of the generator set, obtains the actual operating parameters of the generator set according to the thermodynamic system model, obtains the adjustment parameters of the generator set according to the actual operating parameters, and adjusts the generator set according to the adjustment parameters. Thus, the present application constructs a thermodynamic system model of the generator set based on the heat balance diagram of the generator set, and further obtains adjustment parameters according to the actual operating parameters obtained from the thermodynamic system model to adjust the generator set, reducing the energy consumption of the generator set and improving the economic benefits of the generator set.
[0047] Figure 4 It is a schematic flow chart of another adjustment method of the generator set provided by an embodiment of the present application.
[0048] As Figure 4 shown, the adjustment method of the generator set proposed in this embodiment specifically includes the following steps:
[0049] S401, obtain the heat balance diagram of the generator set.
[0050] In the embodiments of the present application, the heat balance diagram of the pre-set generator set is obtained for subsequent processing.
[0051] S402, call the model building tool of the generator set.
[0052] In the embodiments of the present application, the model building tool is the tool for building the thermodynamic system model. The model building tool of the generator set is called for subsequent model building processing. It should be noted that the model building tool can be Ebsilon (a general thermodynamic modeling configuration software), and the heat balance calculation and simulation of the thermodynamic system can be carried out through Ebsilon.
[0053] S403, run the model building tool, and perform model simulation based on the heat balance diagram to generate a thermodynamic system model.
[0054] In the embodiments of the present application, run the model building tool called in step S402, and generate a thermodynamic system model based on the heat balance diagram obtained in step S201. Those skilled in the art can understand that the corresponding thermodynamic system model can be generated by inputting the heat balance data on the heat balance diagram into the model building tool. For example, by inputting the heat balance data into Ebsilon, the corresponding thermodynamic system model can be obtained.
[0055] The step "obtain the actual operating parameters of the generator set according to the thermodynamic system model" in the above embodiment includes the following steps:
[0056] S404. Conduct tests on the generator set to obtain the test performance parameters of the generator set.
[0057] In the embodiments of the present application, the test performance parameters are the performance parameters obtained when the generator set is being tested. Conduct tests on the generator set to obtain the test performance parameters of the generator set. It should be noted that the test refers to the heating energy consumption test. The test performance parameters may specifically include, but are not limited to, the main performance indicators and economic indicators of the generator set. The high and medium pressure cylinder efficiency, power generation coal consumption, and heating coal consumption rate of the generator set can be measured through the heating energy consumption test, and based on this, the main performance indicators and economic indicators of the generator set, that is, the test performance parameters, can be obtained.
[0058] S405. Modify the thermal system model according to the test performance parameters to obtain the modified thermal system model.
[0059] In the embodiments of the present application, the thermal system model generated in step S403 is modified according to the test performance parameters of the generator set obtained in step S404 to obtain the modified thermal system model. It should be noted that when the test performance parameters are input into the thermal system model, the thermal system model will automatically be modified according to the test performance parameters.
[0060] S406. Obtain the actual operating parameters of the generator set according to the modified thermal system model.
[0061] In the embodiments of the present application, the actual operating parameters of the generator set are obtained according to the modified thermal system model obtained in step S405 for subsequent processing. For example, as mentioned in the above example, the actual operating parameters of Unit 1 and Unit 2 under different operating conditions are calculated through the modified thermal system model. Figure 5 is the actual operating parameter diagram of the generator set under different operating conditions, as Figure 5 shown, from Figure 3 and Figure 5 it is not difficult to see that the deviation between the actual operating parameters and the theoretical operating parameters of the two units is relatively large.
[0062] The step "obtain the adjustment parameters of the generator set according to the actual operating parameters" in the above embodiments includes the following steps:
[0063] S207. Determine the operating boundary diagram of the generator set according to the actual operating parameters.
[0064] In the embodiments of the present application, the operating boundary diagram of the generator set is obtained according to the actual operating parameters obtained in step S206 for subsequent processing. For example, continuing with the above example, according to the actual operating parameters of Unit 1 and Unit 2 respectively, that is Figure 5Based on the actual operating parameters shown, draw the corresponding operating boundary diagram. Figure 6 and Figure 7 are the operating boundary diagrams of Unit 1 and Unit 2 respectively. Specifically, as shown in Figure 6 and Figure 7 Taking the heating load and power generation load as the abscissa and ordinate respectively, draw the line diagrams of the pure condensing condition, boiler maximum load condition, boiler minimum load condition, and maximum steam supply condition according to the actual operating parameters, and the operating boundary diagram of Unit 1 can be obtained. Similarly, draw the line diagrams of the pure condensing condition, boiler maximum load condition, boiler minimum load condition, maximum steam supply condition, and maximum heating capacity according to the actual operating parameters, and the operating boundary diagram of Unit 2 can be obtained.
[0065] S408. According to the operating boundary diagram, obtain the adjustment range and adjustment boundary of the generator set.
[0066] In the embodiments of the present application, the adjustment range refers to the parameter range that needs to be based on when adjusting the generator set, and the adjustment boundary refers to the critical value when adjusting the generator set, that is, the edge part of the adjustment range. According to the operating boundary diagram of the generator set determined in step S407, obtain the adjustment range and adjustment boundary of the generator set for subsequent processing. For example, as shown in Figure 6 and Figure 7 shown, Figure 6 the closed area formed by the four straight lines in is the adjustment range of Generator Set 1, and the edge part is the adjustment boundary of Generator Set 1. Similarly, Figure 7 the closed area formed by the four straight lines in is the adjustment range of Generator Set 2, and the edge part is the adjustment boundary of Generator Set 2.
[0067] S409. Simulate different working conditions of the generator set within the adjustment range and adjustment boundary according to the corrected thermal system model to obtain multiple sets of operating data of the generator set.
[0068] In the embodiments of the present application, according to the corrected thermal system model obtained in step S405, within the adjustment range and adjustment boundary of the generator set in step S408, that is, without exceeding the adjustment range and adjustment boundary, simulate different working conditions of the generator set to obtain multiple sets of operating data of the generator set. Optionally, the operating data includes evaluation indicators in the set dimension. Optionally, the economic indicator can be used as the evaluation indicator in the set dimension. It should be noted that the corrected thermal system model can be used to calculate under changing working conditions to obtain multiple sets of high-density and high-precision operating data corresponding to different working conditions.
[0069] S410. In response to the lowest evaluation indicator in the set dimension of the operating data, determine the adjustment method corresponding to the operating data as the target adjustment method.
[0070] In the embodiments of the present application, the evaluation index is the index evaluated on the set dimension, the adjustment method is the load distribution method for distributing the heating load and the power generation load of the generator set, and the target adjustment method is the load distribution method corresponding to the operating data with the lowest evaluation index on the set dimension. It is determined whether the operating data of multiple generator sets obtained in step S409 meets the requirements, and a group of operating data with the lowest evaluation index on the set dimension is selected therefrom, and the adjustment method corresponding to the operating data is used as the target adjustment method for adjusting the generator set. For example, when the economic index of a group of operating data is the lowest, that is, the economic benefit is the best, adjusting the generator set according to the adjustment method corresponding to this operating data means distributing the heating load and the power generation load of the generator set.
[0071] S411. Adjust the generator set according to the target adjustment method.
[0072] In the embodiments of the present application, the generator set is adjusted according to the target adjustment method determined in step S410 to meet the requirement of the lowest evaluation index on the set dimension. For example, as described in the above example, when the evaluation index is the economic index, the economic index is made the lowest, that is, the economic benefit is the best, by adjusting the generator set. Optionally, the operating data obtained from the corrected thermal system model can be imported into the control system through the control system, and the control system adjusts the generator set even according to the changes in the external network power generation load and the heating load to achieve the distribution of the power generation load and the heating load.
[0073] The adjustment method of the generator set provided by this application includes: obtaining the heat balance diagram of the generator set, invoking the model building tool of the generator set, running the model building tool, performing model simulation based on the heat balance diagram to generate the thermal system model, conducting tests on the generator set to obtain the test performance parameters of the generator set, correcting the thermal system model according to the test performance parameters to obtain the corrected thermal system model, obtaining the actual operating parameters of the generator set according to the corrected thermal system model, determining the operating boundary diagram of the generator set according to the actual operating parameters, obtaining the adjustment range and adjustment boundary of the generator set according to the operating boundary diagram, simulating different operating conditions of the generator set within the adjustment range and adjustment boundary according to the corrected thermal system model to obtain multiple sets of operating data of the generator set, determining that the adjustment method corresponding to the operating data is the target adjustment method in response to the lowest evaluation index on the set dimension in the operating data, and adjusting the generator set according to the target adjustment method. Thus, this application constructs the thermal system model of the generator set based on the heat balance diagram of the generator set, and further obtains the adjustment parameters according to the actual operating parameters obtained from the thermal system model to adjust the generator set, reducing the energy consumption of the generator set and improving the economic benefits of the generator set.
