[0052] It is further understood that although operations are described in a specific order in the accompanying drawings in the embodiments of this disclosure, this should not be construed as requiring these operations to be performed in the specific order or serial order shown, or requiring all of the shown operations to be performed to obtain the desired result.

[0053] It should be noted that all actions involving the acquisition of signals, information, or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where the application is located, and with the authorization granted by the owner of the relevant device.

[0054] Figure 1 This is a block diagram illustrating a heating regulation system according to an exemplary embodiment, applied to a thermal power unit, such as... Figure 1 As shown, the thermal power unit system 10 includes: a water temperature setting module 101 and a water temperature regulating module 102;

[0055] The water temperature setting module 101 is used to automatically set a first water temperature based on the electricity price and the power generation load of the thermal power unit, or to receive manual instructions to set a second water temperature, wherein the first water temperature does not exceed the set temperature range.

[0056] Understandably, the first water temperature is set based on the power generation load of the thermal power unit and the electricity price, which is the grid connection price. The first water temperature can be a specific water temperature within the allowable range of the hot water supply temperature, or it can be a range of water temperatures within the allowable range of the hot water supply temperature. The same applies to the second water temperature set by manual instruction.

[0057] For example, the principle of automatically setting the first water temperature is that the higher the electricity price, the lower the first water temperature; and the higher the power generation load of the thermal power unit, the lower the first water temperature. For instance, when the allowable range of hot water temperature is 70-80 degrees Celsius, the standard electricity price is 1 yuan per kilowatt-hour, and the standard power generation load of the thermal power unit is 100 kilowatt-hours, and the electricity price is 1.5 yuan per kilowatt-hour, and the power generation load of the thermal power unit is 120 kilowatt-hours, the first water temperature can be 55-65 degrees Celsius.

[0058] The water temperature setting module 101 is also used to determine the first water temperature or the second water temperature as the target water temperature according to manual instructions.

[0059] The water temperature regulation module 102 is used to adjust the heat supply according to the temperature deviation between the target water temperature and the actual water temperature through a PID algorithm, so as to regulate the actual water temperature.

[0060] It is understandable that adjusting the heating supply can be based on the temperature deviation between the target water temperature and the actual water temperature, as well as the PID algorithm. The PID algorithm, which combines P (Proportional), I (Integral), and D (Differential) functions, is a control algorithm that performs calculations based on the input water temperature deviation according to the proportional, integral, and derivative functional relationships. Furthermore, the actual water temperature can be adjusted according to preset rules. These preset rules are: when the target water temperature is higher than the actual water temperature, increase the heating supply; when the temperature change per second of the target water temperature is higher than the temperature change per second of the actual water temperature, increase the heating supply.

[0061] In the above technical solution, a first water temperature is automatically set based on the electricity price and the power generation load of the cogeneration unit, or a second water temperature is set based on a manual instruction. The first water temperature does not exceed the set temperature range. The first or second water temperature is determined as the target water temperature based on the manual instruction. The heating supply is adjusted using a PID algorithm based on the temperature deviation between the target and actual water temperatures to regulate the actual water temperature. Through this solution, the water temperature can be automatically set based on the electricity price and power generation load, or it can be manually set. Furthermore, the heating supply can be adjusted based on the deviation between the set target and actual water temperatures to regulate the actual water temperature.

[0062] Optionally, the water temperature setting module 101 is also used to determine the water temperature offset based on the electricity price and the power generation load of the thermal power unit.

[0063] The water temperature setting module 101 is also used to superimpose the water temperature offset with the second water temperature to obtain the third water temperature.

[0064] The water temperature setting module 101 is also used to determine the first water temperature, the second water temperature, or the third water temperature as the target water temperature according to manual instructions.

[0065] Understandably, the water temperature setting module 101 in this heating regulation system has two modes: manual setting and automatic setting. These two modes can operate independently and be switched freely, or they can be combined. In the combined mode, the manually set second water temperature is used as the base water temperature, and an offset is added to this base water temperature using automatic setting to adjust the water temperature. This water temperature offset is determined similarly to the first water temperature; the principle for determining the water temperature offset is that the higher the electricity price, the lower the water temperature offset, and the higher the power generation load of the thermal power unit, the lower the water temperature offset. Therefore, the target water temperature can be based on the automatically set first water temperature, the manually set second water temperature, or a third water temperature obtained by combining the automatic and manual settings.

[0066] For example, when the unit load is not near the lower or upper limit of the unit's allowable load, the water temperature offset output of the automatic setting stage in superposition mode can be 0; the water temperature in automatic setting mode can be the middle value of the allowable water temperature range; when the unit load is close to the lower limit, since the water temperature needs to be increased, the output value of the automatic setting stage in superposition mode can be a positive value, plus the manually set second water temperature, which can increase the water temperature of the thermal power unit, and the water temperature in automatic setting mode can be the upper limit of the allowable water temperature range; when the unit load is close to the upper limit, since the water temperature needs to be decreased, the output value of the automatic setting stage in superposition mode can be a negative value, plus the manually set second water temperature, which can decrease the water temperature of the thermal power unit, and the water temperature in automatic setting mode can be the lower limit of the allowable water temperature range.

[0067] Optionally, Figure 2 This is a block diagram illustrating yet another heating regulation system according to an exemplary embodiment, such as... Figure 2 As shown, the heating regulation system 10 also includes: a heat exchanger 103, a heater 104, a regulating valve 105, and a pressure regulator 106; the heat exchanger 103 and the heater 104 are used to supply heat to the thermal power unit.

[0068] The regulating valve 105 is used to regulate the heat source flow of the heat exchanger 103 in order to regulate the heat supply.

[0069] The voltage regulator 106 is used to adjust the power supply voltage, power supply current, heating power or operating power of the heater 104 to regulate the heat supply.

[0070] Optionally, the heat exchanger 103 can be a steam-circulating water heat exchanger, and the heater 104 can be an electric heater for circulating water, with the electric energy coming from the plant's auxiliary power supply of the thermal power unit. The heater 104 can employ direct heating or indirect heating methods. For example, an electric heater can directly convert electrical energy into heat energy to raise the water temperature; an electrically driven air heat pump can also be used to heat the circulating water, which has the advantage of high heat conversion efficiency; alternatively, an electric heater can first heat a medium such as molten salt, and then the circulating water absorbs the heat from the molten salt to raise the water temperature. This heating method has a large heat storage capacity, which helps to smooth the circulating water temperature and also has an energy storage effect.

[0071] Optionally, the heating regulation system 10 further includes a heating regulation module 107;

[0072] The heating regulation module 107 is used to increase the heating ratio of the heater and decrease the heating ratio of the heat exchanger when the electricity price is lower than the electricity price threshold.

[0073] The heating regulation module 107 is also used to reduce the heating ratio of the heater and increase the heating ratio of the heat exchanger when the electricity price is higher than the electricity price threshold.

[0074] Understandably, the heating regulation module 107 can regulate the water temperature by changing the heating power of the heat exchanger in the thermal power unit, or by changing the electric heating power of the heater. These two methods can be used individually or together to regulate the water temperature. The heating ratio of the heater 104 and the heat exchanger 103 is adjusted according to the electricity price. When the electricity price is below the threshold or is negative, the output of the heater 104 is increased, and the opening of the regulating valve 105 of the heat exchanger 103 is decreased; when the electricity price is high, the output of the heater 104 is decreased, and the opening of the regulating valve 105 of the heat exchanger 103 is increased.

[0075] In the above technical solution, the automatic water temperature setting method and the manual water temperature setting method can be superimposed to obtain the target water temperature; in addition, heat exchangers and heaters can be used to provide heat for the circulating water of the thermal power unit; and the heating ratio of heaters and heat exchangers can be adjusted according to the comparison of electricity price and electricity price threshold. Through the above technical solution, electrical energy and heat energy can be fully utilized according to changes in electricity price, reducing economic losses, increasing the economic benefits of the thermal power unit, and regulating water temperature to improve the stability of unit operation.

[0082] In step S305, the water temperature offset is superimposed with the second water temperature to obtain the third water temperature.

[0083] In step S306, the first water temperature, the second water temperature, or the third water temperature is determined as the target water temperature according to manual instructions.

[0084] Optionally, Figure 5 This is a flowchart illustrating another heating regulation method according to an exemplary embodiment, such as... Figure 5 As shown, the method may also include the following steps.
