[0028] Figure 1 FIG. 6 is a flowchart of a heat unit coordinated control optimization method according to an embodiment of the present application. It should be noted that the heat unit coordinated control optimization method of the embodiments of the present application can be applied to the heat unit coordinated control optimization apparatus of the embodiments of the present application. The heat unit coordinated control optimization apparatus can be configured on an electronic device such as a boiler controller. As shown in FIG. 6, the heat unit coordinated control optimization method can include the following steps. Figure 1

[0029] Step S101, obtaining a current heat supply steam flow, a current unit load, and a current main steam flow in a boiler control instruction.

[0030] The parameter to be adjusted is obtained.

[0031] It should be noted that the unit load in the embodiments of the present application refers to a power generation load.

[0032] ​Step S102, based on the parameter relationship, the current heat supply steam flow is converted into a converted unit load and a converted main steam flow; wherein the parameter relationship includes the relationship between the heat supply steam flow and the unit load and the main steam flow, respectively.

[0033] In some embodiments, the parameter relationship acquisition method comprises:

[0034] Building a thermal state model of the heat supply unit;

[0035] Obtaining the actual operating parameters of the heat supply unit;

[0036] Correcting the parameters of the thermal state model through the actual operating parameters to obtain a corrected thermal state model;

[0037] Based on the corrected thermal state model, a variable condition calculation is performed to obtain load flow data; wherein the load flow data includes unit load, heat supply steam flow and main steam flow;

[0038] Based on the load flow data, the parameter relationship is obtained.

[0039] As a possible implementation, according to the heat balance diagram and other design data of the heat supply unit, a thermal state model of the unit is built by means of thermal calculation software.

[0040] Example 1, select the cold reheat mode of a certain 600MW heat supply unit as the calculation model, and optimize the control logic for the unit cold reheat (industrial steam supply pressure greater than 2.1MPa). According to the heat balance diagram, sliding pressure curve, heat supply index and other design data of the heat supply unit, a thermal state model of the heat supply unit is built by means of thermal calculation software.

[0041] Step 1: According to the heat balance diagram, sliding pressure curve, heat supply index and other design data of the unit, a thermal state model of the unit is built by means of thermal calculation software;

[0042] As a possible implementation, the actual operating parameters of the heat supply unit can be obtained by experiment, for example, turbine performance test. For example, the actual operating parameters can include high and medium pressure cylinder efficiency, steam extraction efficiency, heater end difference, etc., as shown in Table 1 below.

[0043] Table 1:

[0044]

[0045] Specifically, based on the load flow data, the parameter relationship is obtained, comprising:

[0046] Under the condition of the unit load, the relationship between the heat supply steam flow and the main steam flow is calculated; under the condition of the main steam flow, the relationship between the heat supply steam flow and the unit load is calculated.

[0047] As an example, as shown in Table 2 below, the main steam flow data table under different unit loads and different heat supply steam flows can be used to calculate the relationship between the heat supply steam flow and the main steam flow under the same unit load, for example, the relationship between the heat supply steam flow and the main steam flow under the working condition T01 and the working condition T04 is calculated.

[0048]

[0049] Similarly, according to the thermal state model, the data table of the heat supply steam flow under different main steam flows and different unit loads can be obtained, and the relationship between the unit load and the heat supply steam flow under the same main steam flow is obtained.

[0050] As an example, through calculation, under different unit load working conditions, the influence of the heat supply steam flow on the unit load is about 0.287KW.h / t, and converted into the main steam flow: the increase of the main steam flow caused by the increase of 1 ton of heat supply steam flow is about 0.85t / h.

[0051] In step S103, based on the converted unit load and the converted main steam flow, the current unit load and the current main steam flow are adjusted to obtain the target energy value of the heat supply unit.

[0052] Specifically, based on the converted unit load and the converted main steam flow, the current unit load and the current main steam flow are adjusted to obtain the target energy value of the heat supply unit, including:

[0053] The converted unit load and the converted main steam flow are superimposed with the corresponding current unit load and the current main steam flow respectively to obtain the target energy value of the heat supply unit.

[0054] That is, the heat supply steam flow converted into the electric load or the main steam flow is sent to the boiler main control loop, and the boiler main control loop performs calculation, and the converted electric load or main steam flow is added to the unit electric load instruction and the main steam flow instruction respectively to obtain the target value of the energy demand of the heat supply unit.

[0055] It should be further pointed out that after conversion, the target energy value of the heat supply unit cannot exceed the maximum load of the heat supply unit.

[0056] Therefore, further, according to the parameter relationship and the load range limit value of the heat supply unit, an operation domain of the heat supply steam flow of the heat supply unit is determined; the operation domain of the heat supply steam flow is used to constrain the target energy value of the heat supply unit.

[0057] It can be understood that, as shown in Figure 2 The determination of the load range limit value can obtain the operation domain of the heat supply steam flow (corresponding to the heat supply extraction flow in the figure) of the heat supply unit, and the heat supply capacity of the heat supply unit outside the operation domain cannot meet the requirement.

[0058] In step S104, operation control is performed according to the target energy value of the heat supply unit.

[0059] After obtaining the target energy value of the heat supply unit, operation control is performed according to the target energy value.

[0060] As shown in the cold reheat heat supply system of the thermal power unit, the cold reheat steam supply mode of the steam turbine is taken as an example, the current heat supply steam flow (i.e. the heat supply flow in the figure) is obtained from the heat supply instruction, the heat supply flow is converted through a formula, the converted unit load (the converted load in the formula) and the converted main steam flow are obtained; the converted main steam flow and the current main steam flow (the main steam flow in the formula) are superimposed to obtain the target main steam flow, and the target main steam flow is used to adjust the main steam flow accumulation and the boiler oxygen content and other parameters; the converted unit load and the current unit load (the unit load in the formula) are superimposed to obtain the target unit load, and the target unit load is used to adjust the desuperheating water flow, the total fuel quantity, the boiler load and the desorption flue adjusting valve position and other parameters. Figure 3 Figure 3 That is, the result of the boiler main control loop operation is sent to the air, coal, water and other sub-loops, so that the energy demand of the heat supply unit and the timely optimal matching of the energy output on the boiler side can be realized, thereby improving the automatic adjustment quality of the heat supply unit.
