[0055] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] According to an embodiment of the present invention, an embodiment of a heat supply unit control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0057] In this embodiment, a heat supply unit control method is provided, which can be used for the above-mentioned terminal devices, such as a computer, etc. As Figure 1 shown, the heat supply unit control method includes the following steps:

[0058] Step S1: Obtain the target load and the actual load of the heat supply unit. Specifically, the target load instruction is the target load required to be output by the heat supply unit according to the specified requirements, and the actual load is the load actually output by the heat supply unit at the current moment. It is necessary to adjust to make the actual load equal to the target load.

[0059] Step S2: Calculate the coordinated load instruction based on the target load. Specifically, the coordinated load instruction starts from the initial load and changes with time based on the variable load rate. When the coordinated load instruction reaches the target load of the unit, the coordinated load instruction no longer changes and stabilizes at the target load. This process is to ensure the normal operation and stable operation of the heat supply unit.

[0060] Step S3: Calculate the load setting value according to the target load and the actual load. Specifically, by calculating the load setting value, the situation of over-regulation can be effectively avoided, and the safe operation of the heat supply unit can be ensured.

[0061] Step S4: Calculate the real-time load deviation based on the actual load, the coordinated load instruction, and the load set value. Specifically, by calculating the real-time load deviation, the coordinated control system of the boiler and turbine is flexibly adjusted, improving the response speed and load change rate of the entire heating unit and enhancing the flexibility of the heating unit.

[0062] Step S5: Adjust the load of the heating unit based on the load set value and the real-time load deviation. Specifically, the heating unit includes a coordinated control system for the boiler and turbine, a throttling control system for heating extraction steam, and a throttling control system for condensate water. By comprehensively considering the response speed and peak shaving potential of the system, the three systems are adjusted respectively, realizing the idea of "layered" control, fully utilizing the energy storage of each part of the heating unit, and maximizing the flexibility of the heating unit.

[0063] Through the above steps S1 to S5, the heating unit control method provided by the embodiment of the present invention, by fully utilizing the energy storage of each part of the heating unit, accumulates the power increment brought by the throttling technology on the basis of the original load change rate of the unit, greatly shortening the response speed of the heating unit, improving the response speed and load change rate of the heating unit, enhancing the flexibility of the heating unit, and providing strong support for the large-scale grid connection of renewable energy.

[0064] Specifically, in one embodiment, the above step S2 is as Figure 2 shown, and specifically includes the following steps:

[0065] Step S21: Obtain the load change rate, initial load, and current operating time of the heating unit.

[0066] Step S22: Calculate the target time required to reach the target load from the initial load based on the load change rate, target load, and initial load.

[0067] Step S23: Compare the current operating time with the target time.

[0068] Step S24: If the current operating time is less than the target time, the coordinated load instruction is the sum of the load changes accumulated by the initial load and the current operating time.

[0069] Step S25: If the current operating time is greater than the target time, the coordinated load instruction is the target load.

[0070] Specifically, the calculation method of the coordinated load instruction is as follows:

[0071]

[0072] In the formula: Pe1 is the coordinated load instruction; Pe00 is the initial load; Pe0 is the target load; rate0 is the load change rate of the heating unit; t is the real-time time; t sThe time required to coordinate the load command to reach the target load.

[0073] Through the above process, it can be understood that the coordinated load command starts from the initial load and increases with time based on the variable load rate. When the coordinated load command reaches the unit target load, the coordinated load command no longer changes and stabilizes at the target load. This process is to ensure the normal operation and stable operation of the heating unit.

[0074] Specifically, in one embodiment, the load setting value includes: the first load setting value of the heating steam extraction throttling system and the second load setting value of the condensate throttling system. The above step S3 is as Figure 3 shown and specifically includes the following steps:

[0075] Step S31: Obtain the maximum load increment of the heat network, the maximum load increment of the condensate, the preset steam extraction throttling load value, and the preset condensate throttling load value. Specifically, the maximum load increment of the heat network is the maximum load increment of the heat network obtained according to the current operating state of the heat network; the maximum load increment of the condensate is the maximum load increment that the condensate throttling system can provide under the deaerator water level limit.

[0076] Step S32: Calculate the first load setting value of the heating steam extraction throttling system according to the maximum load increment of the heat network, the preset steam extraction throttling load value, the target load, and the actual generated load. Specifically, by comprehensively comparing and calculating to obtain the first load setting value, it can effectively avoid the occurrence of over-regulation of the heating steam extraction throttling system and ensure the safe operation of the heating steam extraction throttling system.

[0077] Step S33: Calculate the second load setting value of the condensate throttling system according to the maximum load increment of the condensate, the preset condensate throttling load value, the target load, the actual generated load, and the first load setting value. Specifically, by comprehensively comparing and calculating to obtain the second load setting value of the condensate throttling system, it can effectively avoid the occurrence of over-regulation of the condensate throttling system and ensure the safe operation of the condensate throttling system.

[0078] Specifically, in one embodiment, the above step S32 is as Figure 4 shown and specifically includes the following steps:

[0079] Step S321: Calculate the first load difference based on the target load and the actual generated load.

[0080] Step S322: Compare the maximum load increment of the heat network, the preset steam extraction throttling load value, and the first load difference, and select the minimum value as the first load setting value of the heating steam extraction throttling system.

[0081] Specifically, the process of calculating the first load setting value is as follows:

[0082] Pe2 = min{ΔPe h , Pe h , Pe0 - Pe4}

[0083] Wherein, Pe2 is the first load setting value of the heating extraction throttle system; ΔPe h is the maximum load increment of the heat network obtained according to the current operating state of the heat network; Pe h is the extraction throttle load value preset by the operator; Pe4 is the actual generated load of the unit.

[0084] By comprehensively comparing and calculating to obtain the first load setting value, it can effectively avoid over-regulation of the heating extraction throttle system and ensure the safe operation of the heating extraction throttle system.

[0085] Specifically, in an embodiment, step S33 above, as Figure 5 shown, specifically includes the following steps:

[0086] Step S331: Calculate the second load difference based on the target load, actual generated load, and the first load setting value.

[0087] Step S332: Compare the maximum condensate load increment, the preset condensate throttle load value, and the second load difference, and select the minimum value as the second load setting value of the condensate throttle system.

[0088] Specifically, the process of calculating the second load setting value is as follows:

[0089] Pe3 = min{ΔPe c , Pe c , Pe0 - Pe4 - Pe2}

[0090] Wherein, Pe3 is the second load setting value of the condensate throttle system; ΔPe c is the maximum condensate load increment that can be provided under the deaerator water level limit; Pe c is the condensate throttle load value preset by the operator.

[0091] By comprehensively comparing and calculating to obtain the second load setting value of the condensate throttle system, it can effectively avoid over-regulation of the condensate throttle system and ensure the safe operation of the condensate throttle system.

[0092] Specifically, in an embodiment, step S4 above, as Figure 6 shown, specifically includes the following steps:

[0093] Step S41: Calculate the real-time load value by the actual generated load and the load setting value.

[0094] Step S42: Take the difference between the real-time load value and the coordinated load instruction as the real-time load deviation.

[0095] Specifically, the calculation method of the real-time load deviation is as follows:

[0096] Pe l = Pe2 + Pe3 + Pe1

[0097] ΔPe0 = Pe4 - Pe l

[0098] In the formula, Pe l is the real-time load value sent by the coordinated control system of the boiler and turbine, and △Pe o is the real-time load deviation input to the coordinated control system of the boiler and turbine.

[0099] By calculating the real-time load deviation, the coordinated control system of the boiler and turbine is flexibly adjusted, improving the response speed and load change rate of the entire heating unit and enhancing the flexibility of the heating unit.

[0100] Specifically, in an embodiment, the heating unit includes a coordinated control system of the boiler and turbine, a throttling control system for heating steam extraction, and a throttling control system for condensate. The load set value includes: a first load set value of the throttling control system for heating steam extraction and a second load set value of the throttling control system for condensate. The above step S5, as Figure 7 shown, specifically includes the following steps:

[0101] Step S51: Extract the first load set value from the load set value to calculate the throttling flow rate of heating steam extraction, and perform variable load adjustment on the throttling control system for heating steam extraction through the throttling flow rate of heating steam extraction. Specifically, the calculation method of the throttling flow rate of heating steam extraction is as follows:

[0102]

[0103] In the formula: G gr is the throttling flow rate of heating steam extraction; w gr is the work done per unit heating steam extraction flow rate obtained by the equivalent heat drop method; Pe2 is the first load set value.

[0104] Step S52: Extract the second load set value from the load set value to calculate the throttling flow rate of condensate, and perform variable load adjustment on the throttling control system for condensate through the throttling flow rate of condensate. Specifically, the calculation method of the throttling flow rate of condensate is as follows:

[0105]

[0106] In the formula: G cond is the throttling flow rate of heating steam extraction; w condΔP1 is the increase in the unit power of the unit when the condensate flow rate changes obtained by the equivalent heat drop method; Pe3 is the second load set value.

[0107] Step S53: Perform variable load adjustment on the coordinated control system of the boiler-turbine unit through the real-time load deviation.

[0108] Specifically, through the combined action of extraction steam throttling and condensate throttling for heating, and coupling with the coordinated control system, the variable load of the entire heating unit is adjusted, fully utilizing the energy storage of each part of the heating unit. Based on the original variable load rate of the unit, the power increment brought by the throttling system is accumulated, greatly shortening the response speed of the heating unit, improving the response speed and variable load rate of the heating unit, enhancing the flexibility of the heating unit, and the implementation method is simple, without the need to add equipment, with a short recovery period, providing strong support for the large-scale grid connection of renewable energy.
