Description

Technical Field

[0001] The present disclosure relates to the technical field of thermal power generation, and in particular to a control method and device for a condensate pump, an electronic device, and a storage medium. Background Art

[0002] In the thermal power generation system, the condensate pump is one of the important equipment for transporting condensate. The steam turbine generates electricity by steam work. The condensate formed after the steam is cooled is stored in the condenser. The condensate pump extracts the condensate from the condenser and transports it to the deaerator.

[0003] In the related technology of the control method of the condensate pump, a double condensate pump is usually used to transport the condensate, and the double condensate pumps are operated with the same power frequency or the same variable frequency.

[0004] When the unit load changes, the output flow and pressure of the dual condensing pumps running at the same power frequency often do not match the actual demand, resulting in increased throttling losses, making the energy-saving effect of the dual condensing pumps running at the same power frequency lower; when the unit load is low, the energy-saving effect of the dual condensing pumps running at the same variable frequency is lower. Therefore, whether the dual condensing pumps are running at the same power frequency or the same variable frequency will result in a lower energy-saving effect of the dual condensing pumps.

[0052] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0053] The following describes a control method and device for a condensate pump, an electronic device, and a storage medium according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0054] Figure 1 A flow chart of a condensate pump control method provided in an embodiment of the present disclosure.

[0055] like Figure 1 As shown, the method is applied to the control system of the condensate pump, and the method comprises the following steps:

[0056] Step 101, obtaining a real-time water level value of a deaerator connected to a double condenser pump, and obtaining a real-time pressure value of a first water supply regulating valve of the deaerator; the double condenser pump includes a power frequency pump and a variable frequency pump.

[0057] The deaerator is an important equipment in the thermal power generation system, which is used to remove oxygen from the condensate to prevent corrosion and oxidation. After being heated and deoxygenated in the deaerator, the condensate is sent to the boiler or other water-using equipment. The real-time water level value refers to the current water level inside the deaerator. The real-time water level value can be obtained by real-time monitoring of the water level sensor. However, it should be clear that this statement is not intended to limit the real-time water level value to only be monitored by the water level sensor, and it can also be measured by other methods.

[0058] The first water supply regulating valve is a regulating valve located at the inlet of the deaerator, which is used to control the flow of condensate entering the deaerator. By adjusting the opening and closing degree of the first water supply regulating valve, the water level of the deaerator can be adjusted. The real-time pressure value refers to the pressure value at the inlet of the deaerator. The real-time pressure value can be obtained by real-time monitoring of the pressure sensor, but it should be clear that this statement is not intended to limit the real-time pressure value to only be monitored by the pressure sensor, and can also be measured by other methods. The real-time pressure value reflects the pressure state of the condensate when it enters the deaerator.

[0059] The power frequency pump refers to a condensing pump that runs at a fixed frequency (i.e., power frequency). The speed and flow of the power frequency pump are fixed and cannot be adjusted according to actual needs. The variable frequency pump refers to a condensing pump that can run at a variable frequency. By changing the frequency, the pump speed and flow can be accurately adjusted.

[0060] By real-time monitoring of the system's operating status, it can be ensured that the system operates within a safe range and prevent system failures or accidents caused by abnormal water levels or pressures, thereby ensuring the safe and stable operation of the entire system.

[0061] Step 102, when it is determined that the real-time water level value is not within the preset safety water level range, adjust the opening degree of the second water supply regulating valve of the industrial frequency pump until the real-time water level value is within the preset safety water level range; the second water supply regulating valve is located between the industrial frequency pump and the first water supply regulating valve.

[0062] The preset safe water level range refers to a water level interval range set to ensure the normal operation of the deaerator. When the real-time water level value is within the preset safe water level range, the water level of the deaerator is considered to be safe. The second water supply regulating valve is a regulating valve located between the power frequency pump and the first water supply regulating valve. By adjusting the opening and closing degree of the second water supply regulating valve, the output flow of the power frequency pump can be regulated, thereby further affecting the water level of the deaerator. The opening and closing degree of the second water supply regulating valve refers to the current degree of opening of the second water supply regulating valve, expressed in percentage or other units. Changes in the opening and closing degree of the second water supply regulating valve will directly affect the flow through the second water supply regulating valve. The embodiment of the present disclosure does not limit the value of the preset safe water level range, and can be specifically set according to actual business needs.

[0063] For example, when the real-time water level value is higher than the upper limit of the preset safe water level range, it means that the water level of the deaerator is too high, and the opening degree of the second water upper regulating valve needs to be reduced to reduce the condensate flow entering the deaerator until the real-time water level value is within the preset safe digital range. When the real-time water level value is lower than the lower limit of the preset safe water level range, it means that the water level of the deaerator is too low, and the opening degree of the second water upper regulating valve needs to be increased to increase the condensate flow entering the deaerator until the real-time water level value is within the preset safe digital range.

[0064] Changes in water level will directly affect the performance and efficiency of the deaerator. Keeping it within the safe water level range ensures that the deaerator can continue to effectively remove oxygen from the condensate, prevent corrosion and oxidation, and maintain the stable operation of the entire system.

[0065] Step 103: When it is determined that the real-time pressure value is not within the preset safety pressure range, adjust the frequency of the variable frequency pump until the real-time pressure value is within the preset safety pressure range.

[0066] The preset safety pressure range refers to a pressure interval range set to ensure the normal operation of the deaerator and its upstream pipeline. When the real-time pressure value is within this range, the system pressure is considered safe. The frequency of the variable frequency pump refers to the frequency at which the variable frequency pump is currently running, and this value can be adjusted through the control system. Changing the frequency can change the speed and flow rate of the pump, thereby achieving regulation of the system pressure. The embodiments of the present disclosure do not limit the value of the preset safety pressure range, and the specific value can be set according to actual business needs.

[0067] For example, when the real-time pressure value is higher than the upper limit of the preset safety pressure range, it means that the pressure at the inlet of the deaerator is too high, and the frequency of the variable frequency pump needs to be reduced to reduce the output pressure until the real-time pressure value is within the preset safety pressure range. When the real-time pressure value is lower than the lower limit of the preset safety pressure range, it means that the pressure at the inlet of the deaerator is too low, and the frequency of the variable frequency pump needs to be increased to increase the output pressure until the real-time pressure value is within the preset safety pressure range.

[0068] The variable frequency pump changes the output pressure and flow rate by adjusting the frequency, thereby achieving energy saving and consumption reduction. When the real-time pressure value deviates from the preset safe pressure range, by accurately adjusting the frequency of the variable frequency pump, energy efficiency can be maximized and operating costs can be reduced while ensuring the safety and stability of the system.

[0069] The control method of the condenser pump provided by the present disclosure obtains the real-time water level value of the deaerator connected to the double condenser pump, and obtains the real-time pressure value of the first water supply regulating valve of the deaerator; the double condenser pump includes a power frequency pump and a variable frequency pump; when it is determined that the real-time water level value is not within the preset safe water level range, the opening and closing degree of the second water supply regulating valve of the power frequency pump is adjusted until the real-time water level value is within the preset safe water level range; the second water supply regulating valve is located between the power frequency pump and the first water supply regulating valve; when it is determined that the real-time pressure value is not within the preset safe pressure range, the frequency of the variable frequency pump is adjusted until the real-time pressure value is within the preset safe pressure range. Compared with the related art, the embodiment of the present disclosure runs the power frequency pump and the variable frequency pump at the same time. Since the power frequency pump has a better energy-saving effect in controlling the water level, and the variable frequency pump has a better energy-saving effect in controlling the pressure, the power frequency pump and the variable frequency pump run at the same time, thereby improving the energy-saving effect of the double condenser pump.

[0070] As a refinement of step 102, when adjusting the opening degree of the second water supply regulating valve of the industrial frequency pump until the real-time water level value is within the preset safe water level range, it can be achieved by, but not limited to, the following method: adjusting the opening degree of the second water supply regulating valve in a direction so that the real-time water level value approaches the preset safe water level range until the real-time water level value is within the preset safe water level range.

[0071] For ease of understanding, an example is provided. Assume that there is a deaerator connected to a double condensate pump, and its preset safe water level range is 1.5 meters to 2.0 meters. The current real-time water level value is 1.3 meters, which is lower than the lower limit of the preset safe water level range. In order to adjust the real-time water level value to the preset safe water level range, it is necessary to increase the opening degree of the second water supply regulating valve to increase the amount of water entering the deaerator until the real-time water level value is within the preset safe water level range.

[0072] In thermal systems, maintaining an appropriate water level can improve heat exchange efficiency and reduce energy waste. By adjusting the opening and closing degree of the second water supply valve to control the water level, energy efficiency can be improved and operating costs can be reduced while ensuring system safety and stability.

[0073] As a refinement of the above embodiment, when adjusting the opening and closing degree of the second water supply regulating valve until the real-time water level value is within the preset safety water level range, it can be achieved by but not limited to the following method: adjusting the opening and closing degree of the first water supply regulating valve and adjusting the opening and closing degree of the second water supply regulating valve in a direction so that the real-time water level value approaches the preset safety water level range until the real-time water level value is within the preset safety water level range.

[0074] For ease of understanding, an example is provided. Assume that there is a deaerator connected to a double condensation pump, and its preset safe water level range is 1.8 meters to 2.2 meters. The current real-time water level value is 1.6 meters, which is lower than the lower limit of the preset safe water level range. First, gradually increase the opening and closing degree of the first water supply regulating valve. Since the first water supply regulating valve is closest to the entrance of the deaerator, its adjustment may have a more direct and significant impact on the water level. As the opening and closing degree of the first water supply regulating valve increases, the real-time water level value begins to gradually rise. Since the speed at which the real-time water level value rises is not fast enough, it is necessary to adjust the opening and closing degree of the second water supply regulating valve. The second water supply regulating valve is located behind the water outlet of the power frequency pump, and its adjustment can make more detailed adjustments to the water level entering the deaerator. When the real-time water level value reaches 2.0 meters, it is just within the preset safe water level range (1.8 meters to 2.2 meters), stop adjusting the opening and closing degree of the first water supply regulating valve and the second water supply regulating valve.

[0075] The water level is one of the key factors for the stable operation of the system. Keeping it within the preset safe water level range can ensure the stability and reliability of the system and prevent system fluctuations or failures caused by abnormal water levels.

[0076] As a refinement of the above embodiment, when adjusting the opening and closing degree of the first water supply regulating valve and adjusting the opening and closing degree of the second water supply regulating valve, the following methods may be adopted but are not limited to: Figure 2 As shown, Figure 2 A flow chart of a method for adjusting the opening and closing degree of a water supply regulating valve provided in an embodiment of the present disclosure includes:

[0077] Step 201, obtaining the changing speed of the real-time water level value.

[0078] The change rate refers to the rate at which the real-time water level changes over time, that is, the change in the water level per unit time. It reflects how fast the water level rises or falls. Dividing the change in the real-time water level by the time interval gives the change rate of the real-time water level. This speed is usually expressed as the change in water level per unit time, such as meters per second, centimeters per minute, etc.

[0079] Monitoring the rate of change is done to achieve more effective control, ensuring that the deaerator water level remains within the range for safe and economical operation.

[0080] Step 202: if the change speed is greater than a preset threshold, the opening degree of the second water supply regulating valve is adjusted, and the opening degree of the first water supply regulating valve is stopped.

[0081] When the water level changes too quickly, if the opening and closing of the two valves are adjusted at the same time, the water level may fluctuate too much, or even exceed the preset safety range. To avoid this, the system chooses to only adjust the second water supply valve, which has a relatively small impact on the water level or is easier to control precisely, and stops adjusting the first water supply valve, which may have a greater impact on the water level, to prevent overadjustment. The preset threshold value can be any value, and the embodiment of the present disclosure does not limit the value of the preset threshold value, which can be set specifically according to actual business needs.

[0082] Step 203, if the change speed is less than or equal to the preset threshold, then adjusting the opening degree of the second water supply regulating valve and adjusting the opening degree of the first water supply regulating valve are executed.

[0083] When the water level changes slowly, the system is in a relatively stable state. At this time, adjusting the opening and closing of the two valves at the same time can more effectively control the water level. By adjusting the two valves in coordination, the target water level can be reached faster, improving the response speed and efficiency of the system.

[0084] As a refinement of step 103, when adjusting the frequency of the variable frequency pump until the real-time pressure value is within the preset safety pressure range, it can be achieved in the following manner but is not limited to: adjusting the frequency of the variable frequency pump in a direction that makes the real-time pressure value approach the preset safety pressure range until the real-time pressure value is within the preset safety pressure range.

[0085] For ease of understanding, an example is provided. Assuming that the preset safety pressure range is 1.0 to 1.5, the current real-time pressure value is 0.9, which is lower than the lower limit of the preset safety pressure range. The frequency of the variable frequency pump is gradually increased until the real-time pressure value is within the preset safety pressure range.

[0086] The preset safety pressure range is determined based on the system design and operation requirements. Ensuring that the real-time pressure value is within this range can prevent the system from malfunctioning or being damaged due to excessively high or low pressure. Adjusting the frequency of the variable frequency pump to maintain the real-time pressure value within the preset safety range is a key measure to protect system equipment and ensure stable system operation.

[0087] In practical applications, in order to achieve better energy-saving effects of dual pumps, the industrial frequency pump and the variable frequency pump need to run simultaneously, the industrial frequency pump runs in industrial frequency mode, and the variable frequency pump runs in variable frequency mode. The industrial frequency pump runs at a constant speed, and the energy consumption is relatively stable but may be high. The variable frequency pump can reduce energy consumption while meeting water supply requirements by adjusting the speed to match the actual needs. The use of both can reduce overall energy consumption through the energy-saving effect of the variable frequency pump while ensuring the quality of water supply.

[0088] In one possible implementation of the embodiment of the present disclosure, in order to adjust the pressure value of the variable frequency pump when the industrial frequency pump and the variable frequency pump are running at the same time, such as Figure 3 As shown, Figure 3 A schematic diagram of a variable frequency voltage regulation switching circuit provided by an embodiment of the present disclosure, in Figure 3 In the embodiment of the present disclosure, the condensate pump is replaced by a condensate pump. As long as one of the condensate pumps A and B is operated in a power frequency mode, the remaining condensate pump is operated in a variable frequency mode. Figure 4 As shown, Figure 4 A schematic diagram of a method for controlling water level adjustment of an industrial frequency pump provided in an embodiment of the present disclosure, wherein as long as one of the condensate pump A and the condensate pump B operates in a variable frequency manner, the remaining condensate pump operates in an industrial frequency manner.

[0089] In summary, the embodiments of the present disclosure can achieve the following effects:

[0090] In the embodiment of the present disclosure, the industrial frequency pump and the variable frequency pump are operated simultaneously. Since the industrial frequency pump has a better energy-saving effect in controlling the water level, and the variable frequency pump has a better energy-saving effect in controlling the pressure, the industrial frequency pump and the variable frequency pump are operated simultaneously, thereby improving the energy-saving effect of the double condensation pump.

[0091] Corresponding to the above-mentioned condensate pump control method, the present invention also provides a condensate pump control device. Since the device embodiment of the present invention corresponds to the above-mentioned method embodiment, the details not disclosed in the device embodiment can be referred to the above-mentioned method embodiment, and will not be repeated in the present invention.
