Description

Technical Field

[0001] This invention relates to the field of heating technology, and more specifically, to a power control method, apparatus, and heating system for a heating system. Background Technology

[0002] Currently, large-scale heating projects primarily rely on gas-fired boilers for energy supply. However, due to the high risk and construction difficulty of gas-fired boilers, an increasing number of projects are opting for parallel connection of gas-fired wall-hung boilers. However, because the heating power of gas-fired wall-hung boilers is typically controlled using a fixed-setting, progressively approximating control method, the thermal response speed is slower. This forces users to add a large buffer tank to store energy and address the contradiction between rapid thermal control and slow thermal response, thus necessitating a stable heat output. Furthermore, long piping systems, especially those in residential heating systems where boilers and heat pumps are connected in parallel, result in slow temperature rise in the heating pipes over extended periods. When the total power exceeds the heating demand for a prolonged period, it can easily damage the pipes. Additionally, excessive heat accumulation can trigger the system's self-protection mechanism, causing frequent system starts and accelerating the aging of the energy supply equipment.

[0043] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0044] like Figure 1As shown, in a first embodiment of a power control method for a heating system according to the present invention, the power control method is applied to a multi-energy continuous heating system, wherein the multi-energy continuous heating system includes multiple energy supply devices and multiple heating devices simultaneously connected to the multiple energy supply devices; the power control method includes the following steps: S1, during the operation of the heating devices, monitoring the usage status and power consumption of the heating devices. S2, identifying the first heating device whose usage status has changed, obtaining the power consumption of the first heating device, updating the total output power of all the energy supply devices according to the power consumption of the first heating device, and setting the power output of all the energy supply devices according to the total output power. Specifically, in this multi-energy continuous heating system, multiple energy supply devices simultaneously provide heating power to multiple heating devices, enabling the heating devices to output heat as required. When the heating devices are working, there is a power consumption demand; when the heating devices stop working, their power consumption correspondingly becomes zero, that is, there is no power consumption demand at this time. If the power output of the power supply equipment is set according to the demand of the heating equipment, and a change in the operating status of the heating equipment leads to a significant change in power consumption demand, and the power supply equipment does not respond quickly, the adjustment speed of the entire heating system will slow down. This will cause the heating system to operate in a mismatched state for an extended period, accelerating the aging of the entire system. Therefore, when a change in the operating status of the heating equipment causes a mismatch in the power consumption demand of the entire heating system, the power consumption of the first heating equipment whose operating status has changed is obtained. The total output power of all power supply equipment is then quickly set based on this new total output power. This setting process can be understood as an initial setup. Setting the power output of all power supply equipment includes shutting down some equipment, which can be understood as setting the power output of that equipment to zero. This process quickly brings the power output of the heating system into a state that matches its operating status, preventing the heating system from operating in an abnormal state for an extended period.

[0045] In one embodiment, in step S2, the first heating device whose usage state has changed is confirmed to have its power consumption obtained, and the total output power of the multiple energy supply devices is updated based on the power consumption of the first heating device. This includes: when the first heating device switches from an unused state to an used state, obtaining the target power consumption of the first heating device, and increasing the total output power of all the energy supply devices based on the target power consumption of the first heating device. Obtaining the target power consumption of the first heating device when its usage state switches from an unused state to an used state can be understood as the power consumption required for the first heating device to operate. At this time, the energy consumption of the entire system has increased. Therefore, the target power consumption can be added to the existing total output power to obtain the new total output power that the energy supply devices need to set. It can be understood that this operation is performed on each of the multiple first heating devices when their usage state switches from an unused state to an used state. That is, the final new total output power that the energy supply devices need to set is the sum of the target power consumption of all the first heating devices that have switched from an unused state to an used state, based on the original total output power. The switching of the first heating device's usage status from unused to used can also be understood as the switching of the first heating device's operating status from off to on. That is, when the first heating device is in use, it is in the on state; when the first heating device is not in use, it is in the off state.

[0046] In one embodiment, in step S2, confirming the change in the usage state of the first heating device, obtaining the power consumption of the first heating device, and updating the total output power of the multiple energy supply devices based on the power consumption of the first heating device, includes: when the first heating device switches from a usage state to an unused state, obtaining the historical power consumption of the first heating device, and reducing the total output power of all the energy supply devices based on the historical power consumption of the first heating device. Obtaining the historical power consumption of the first heating device when its usage state switches from a usage state to an unused state can be understood as the power consumption of the first heating device during operation. At this time, the energy consumption of the entire system is reduced, and the historical power consumption can be reduced from the existing total output power to obtain the new total output power required for the energy supply devices. It can be understood that this operation is performed on each of the multiple first heating devices when their usage state switches from a usage state to an unused state; that is, the final new total output power required for the energy supply devices is the original total output power minus the sum of the historical power consumption of all the first heating devices that switched from a usage state to an unused state. The switching of the first heating device's usage status from "used" to "unused" can also be understood as the first heating device's operating state switching from "on" to "off". That is, when the first heating device is in use, it is in the "on" state, and when the first heating device is in unused, it is in the "off" state.

[0047] It is understandable that when some of the primary heating equipment simultaneously switches from an unused state to an active state, and others switch from an active state to an unused state, the above steps can be performed sequentially. After each update of the total output power of all heating equipment, the next update will be based on the updated total output power of the heating equipment.

[0048] In one embodiment, such as Figure 2As shown, the power control method of the present invention further includes: S0, confirming that the second heating device is currently in use, obtaining the sum of the target demand power of all the second heating devices, and setting the total output power of all the power supply devices based on the sum of the target demand power of all the second heating devices. That is, at a certain stage of the operation of the heating system, the operating status of the heating devices can be confirmed, the second heating devices in use can be obtained, the sum of the target demand power of all the second heating devices can be obtained, the total output power of all the power supply devices can be set based on the sum of the target demand power, and step S1 and subsequent operations can be performed based on the total output power. In one embodiment, when the operation is performed at the initial stage of the heating system, that is, at this time it can be understood that there are no second heating devices, and the total output power of the power supply devices can be understood as approximately zero. The total output power of the power supply devices is set based on the addition of the first heating device. At the same time, it can be understood that during the execution process, the second heating devices can be no longer obtained, and the total output power can be updated directly based on the current total output power of the power supply devices.

[0049] In one embodiment of the power control method of the present invention, in step S2, setting the power output of all the power supply devices according to the total output power includes: obtaining the maximum output power and minimum output power of the power supply devices, so as to set the power output of all the power supply devices according to the maximum output power and minimum output power of the power supply devices and the total output power. Specifically, in the process of setting the power output of each power supply device, the maximum output power and minimum output power of each power supply device can be obtained first. The maximum output power of each power supply device can be understood as the power that ensures the power supply device will not overheat and form scale, and the minimum output power of each power supply device can be understood as the power that ensures the power supply device will not overcool and form scale. The maximum output power and minimum output power of each power supply device can be understood as being strongly correlated with the power supply device itself. Different functional devices may have different maximum and minimum output powers. These can be preset based on empirical values. The power output of the power supply devices is set within the range of the maximum and minimum output power of each power supply device.

[0050] In one embodiment, such as Figure 3As shown, the step of setting the power output of all power supply devices according to the maximum and minimum output power of the power supply devices and the total output power includes: A1. Obtaining a plurality of first power supply devices and a plurality of second power supply devices in a preset order; A2. Setting the power output of the plurality of first power supply devices to their corresponding maximum output power, and obtaining a first difference between the total output power and the sum of the output power of all first power supply devices; A3. Obtaining the total power output range of the plurality of second power supply devices according to the maximum and minimum output power of the second power supply devices; A4. Determining whether the first difference exceeds the total power output range of the plurality of second power supply devices. If so, proceeding to step A5; otherwise, proceeding to step A6; A5. Adjusting the number of first power supply devices to update the first power supply devices and the second power supply devices, and proceeding to step A2; A6. Setting the power output of the second power supply devices according to the maximum and minimum output power of the second power supply devices and the first difference.

[0051] In other words, based on the above, the specific setting process for the power output of the power supply equipment is given. The activation sequence of the power supply equipment is set as a preset sequence. Several first power supply equipment are set according to the preset sequence, and after acquiring the first power supply equipment, second power supply equipment is acquired according to the preset sequence. The power output of the first power supply equipment is set to its corresponding maximum output power. Simultaneously, the number of first power supply equipment is selected such that the difference between the total output power of all current power supply equipment and the sum of the power output of all first power supply equipment is the first difference, which can also be understood as the remaining power demand within the total power output range of all second power supply equipment. That is, the number of first power supply equipment can be adjusted during this process. The total power output range of the second power supply equipment can be set according to the maximum and minimum output power of the second power supply equipment. That is, the maximum value of the total power output range of the second power supply equipment is the sum of the maximum output power of all second power supply equipment, and the minimum value is the sum of the minimum output power of all second power supply equipment. When the first difference is within the total power output range of several secondary power supply devices, the power output of all secondary power supply devices can be set based on the maximum and minimum output power of the secondary power supply devices, i.e., the remaining power. It can be understood that power supply devices not set are in a non-operating state.

[0052] In one embodiment, the plurality of second power supply devices can be two, namely a third power supply device and a fourth power supply device. In step A6, setting the power output of the second power supply device based on the maximum and minimum output power of the second power supply device and the first difference includes: setting the third power supply device to its minimum or maximum output power to ensure that the second difference between the first difference and the output power of the third power supply device is within the power range of the fourth power supply device. That is, the power output of any one of the two second power supply devices, such as the third power supply device, can be set to its maximum or minimum output power, and the remaining power at this time, i.e., the second difference, can be obtained, such that the second difference is within the power range of the fourth power supply device.

[0053] In one embodiment, such as Figure 4 As shown, the power control method of the present invention further includes: A7, acquiring the operating parameters of the heating equipment, and adjusting the actual output power of several second energy supply devices according to the operating parameters of the heating equipment. When obtaining the power output setting of each energy supply device, the actual output power of the second energy supply device can be fine-tuned based on the operating parameters of the heating equipment during operation. The adjustment process can be such that when the actual output power of a certain second energy supply device is not its maximum or minimum output power, the actual output power of that second energy supply device can be adjusted first as a quick response.

[0054] In one specific embodiment, the system includes 10 power supply devices, each with a maximum power of 24KW and a minimum power of 10KW. If the total output power of all power supply devices is calculated to be 30KW based on the usage status of the heating equipment, and since 20KW < 30KW < 48KW, then two second power supply devices (i.e., a third and a fourth power supply device) can be set up instead of a first power supply device. The fourth power supply device can be used to output the minimum load, which is 10KW, while the third power supply device outputs 14KW, which is 58% of its maximum load. During fine-tuning, the load of the third power supply device can be adjusted until it is fully loaded or its output equals its minimum load. Then, the fourth power supply device can be adjusted, using a smooth transition to reduce the adjustment error introduced by the adjustment. To avoid the problem of simultaneously adjusting the output of two power supply devices, which can easily lead to significant output changes from small adjustments, if the total output power of all power supply devices is calculated to be 36KW based on the usage status of the heating equipment, and the output of the fourth power supply device is set to the minimum load, then the remaining load will exceed the maximum load of the third power supply device. Therefore, the third power supply device should be set to full load, and the fourth power supply device should be set to output 12KW and adjusted. Thus, during fine-tuning, the load of the fourth power supply device should be adjusted until the fourth power supply device is at full load or its output equals its minimum load. If the total output power of all heating equipment is calculated to be 100KW based on its usage status, then setting up three primary heating devices results in a remaining power of 100KW - 24*3 = 28KW, meaning 20KW < 28KW < 48KW. The remaining 28KW is distributed among the third and fourth heating devices. If the third heating device is at full load, this remaining power is 6KW. Since the minimum power of a single heating device is 10KW, the third heating device cannot be at full load. Therefore, the fourth heating device can be set to its minimum load of 10KW, allowing the third heating device to be set to a load of 18KW. The selection of the primary heating devices follows the order of the heating devices in the control sequence. After selecting the primary heating device, the next two heating devices are selected as secondary heating devices, ensuring that the minimum and maximum power of these two secondary heating devices are included in the remaining required power. This process allows for two power supply devices to be in a smooth power distribution control state at any given time. One of these two second power supply devices is fast-response, while the non-fast-response second power supply device exists to cooperate with the fast-response second power supply device.

[0055] In one specific embodiment, such as Figure 5As shown, multiple heating devices can include underfloor heating, swimming pool heating, and shower heating. 1 is the primary side outlet water temperature probe, 2 is the primary side return water temperature probe, 3 is the secondary side outlet water temperature probe, 4 is the secondary side circulation flow sensor, 5 is the secondary side return water temperature probe, 6 is the water tank temperature probe, 7 is the domestic water flow sensor, 8 is the swimming pool temperature probe, 9 is the domestic water inlet temperature probe, 10 is the first step-in tee, and 11 is the second step-in tee. The power requirement for underfloor heating can be determined based on the corresponding flow rate, temperature rise rate, and system efficiency. The corresponding power requirement is P1 = 70ηΔT1xL1, where ΔT1 is the temperature change of the underfloor heating system (in °C / s), L1 is the volume of water flowing through the underfloor heating output side in 1 second, and η is the system efficiency, which is the ratio of energy provided by the power supply equipment to the energy consumed by the heating equipment. Energy transfer involves losses and cannot reach 100%. The flow rate detected by the water flow sensor 4 is the flow rate of the heating circuit. The flow rate corresponding to each heating device can be obtained based on the opening degree of the step tee 10. For example, when the opening degree of the first step tee 10 is 80%, 80% of the flow from the water flow sensor 4 flows through the second step tee 11, and 20% flows to the underfloor heating. When the opening degree of the second step tee 11 is 0%, the flow from the second step tee 11 flows entirely to the water tank. When the opening degree of the second step tee 11 is 80%, 80% of the total flow from the second step tee 11 flows to the swimming pool, and 20% flows to the water tank. The power requirement for swimming pool heating can be determined based on its corresponding flow rate, temperature rise rate, and heating efficiency. The corresponding required power is P2 = 70ηΔT2xL2, where ΔT2 is the set temperature change of the swimming pool in °C / s, and L2 is the volume of water flowing through the swimming pool flow sensor in 1 second. The power requirement for bathing heating can be determined based on its corresponding flow rate, temperature rise rate, and heating efficiency. The corresponding power requirement is P3 = 70ηΔT3 x L3, where ΔT3 is the temperature change of the shower setting in °C / s, and L3 is the volume of water flowing through the shower flow sensor in 1 second. Meanwhile, when there is a need for pool heating, the pool's heat capacity is relatively large, and the usage frequency is low, the temperature drop rate will not cause the system to start frequently. Therefore, pool heating can be stopped directly after the pool reaches the target temperature. When underfloor heating, pool heating, and shower heating are all in use simultaneously, P... 总 =P1 + P2 + P3, where P 总This represents the total output power of all power supply equipment. When pool heating is shut down, this total output power is directly removed from P3, and the power output of each power supply equipment is reset. If any of P1, P2, or P3 experiences a significant change, the temperature of the secondary side outlet water temperature probe may experience a large abrupt change. This process will likely reach a peak value from a stable value within 5 seconds. If the power supply equipment power is not reduced in time, it may lead to overheating of the primary side inlet pipes or even damage to the power supply equipment. If the power supply equipment power is reduced too low while a large amount of water is being used in the tank, the water temperature in the tank will drop significantly during the time it takes to restart the power supply equipment. A minimum power P is set for all primary side power supply equipment. Min and P Max In terms of control, it can achieve seamless power control.
