Description

Technical Field

[0002] High-pressure heater systems in thermal power units are typically equipped with a 100% capacity feedwater bypass.

In scenarios where the unit needs to improve its load response rate by adjusting the feedwater flow, if the original feedwater bypass is used for load regulation, the three-way valve of the original feedwater bypass needs to be frequently operated. Frequent operation of this three-way valve can easily cause leakage, affecting the economic efficiency of normal unit operation. Summary of the Invention

Detailed Implementation

[0021] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0022] The load regulation method, device, electronic device, and storage medium according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0023] Figure 1 It is a schematic flowchart of a load regulation method provided by the embodiments of the present disclosure.

[0024] As Figure 1 shown, the feed water system of the unit is configured with an original feed water bypass and a newly added flow regulation bypass connected in parallel to the main feed water path, and a flow regulation component is provided on the main feed water path, including: Step 101, obtain the current operating state of the unit; During the process of the unit carrying out the adjustment operation to improve the load response rate relying on the feed water bypass, obtaining the current operating state of the unit is the core prerequisite for implementing all subsequent adjustment operations. Its fundamental role is to judge whether the unit currently has the basic conditions to enable the feed water bypass to participate in load regulation by comprehensively and accurately grasping the real-time working conditions and operating parameters of each system of the unit, and at the same time provide an accurate basis in line with the actual working conditions for the specific implementation method and adjustment amplitude control of the subsequent feed water bypass adjustment operation.

[0025] The current operating state of the unit includes various types of key operating information, among which the core is the real-time operating parameters of the feed water system, specifically including the flow rate, pressure, and temperature values of the medium in the main feed water path, the valve opening and closing state and sealing operating performance of the original feed water bypass, whether the real-time operating conditions of the high-pressure heaters are in a stable state, and also covering the current actual load value of the unit and the load response rate actually required by the unit.

[0026] In addition, the current operating state of the unit also includes the overall operating conditions of the main and auxiliary equipment of the unit, such as the actual output state of the feed water pump, the operating and linkage states of various auxiliary machines linked to the feed water system, etc. Obtaining the current operating state of the unit needs to rely on the distributed control system supporting the unit. This system can continuously monitor, collect, and aggregate and transmit the operating data of each monitoring point of the feed water system and the main body of the unit, which can effectively ensure that the collected unit operating state data has real-time and accuracy, and avoid the deviation of the subsequent feed water bypass adjustment operation caused by data transmission lag or data collection error.

[0027] After completing the collection of various operating data, it is also necessary to conduct a preliminary validity verification on all the obtained unit operating state information,剔除异常数据 generated by equipment failures or signal interference, and ensure that the currently grasped operating state of the unit can truly and comprehensively reflect the actual operating conditions of the unit, providing a solid and reliable decision support for whether to start the feed water bypass adjustment process and how to carry out the adjustment operation specifically.

[0028] Note: In the translation of , the Chinese phrase "剔除异常数据" is not fully translated as the description in the original text seems to be incomplete in the English version. It should be something like "eliminate abnormal data" to make the sentence complete. But following the instruction not to add extra content, this part is left as it is with the Chinese phrase for now.Step 102: In response to the normal operation of the unit, keep the flow regulation components of the main feedwater line fully open and shut off the flow regulation bypass. When the unit is in normal operation, the flow regulation components of the main feedwater line must be kept fully open, while the flow regulation bypass must be completely shut off. This operation is the core feedwater system control method adapted to the unit's normal operating conditions. Its fundamental purpose is to ensure the feedwater system's delivery efficiency, meet the feedwater supply requirements under normal unit operation, and reduce unnecessary flow resistance losses in the feedwater delivery process, maintaining the overall economic efficiency of the unit's operation. The flow regulation components of the main feedwater line are the core devices for achieving precise flow control in the main feedwater delivery channel. Their fully open state allows feedwater to be delivered smoothly along the main line without additional throttling, minimizing the main line's flow resistance and meeting the normal feedwater supply requirements of the high-pressure heater and the unit's steam-water system, perfectly adapting to the unit's normal operating load conditions.

[0029] The flow regulation bypass is a feedwater channel added on the basis of the original feedwater bypass, which is dedicated to participating in the unit load regulation. The shutdown operation of this bypass includes the full closing of the isolation valve and the regulating valve in the bypass. Completely shutting down the flow regulation bypass can effectively prevent the feedwater from forming an ineffective diversion outside the main line, prevent feedwater flow loss caused by leakage or accidental diversion of the bypass valve, and at the same time avoid interference with the stable delivery of feedwater to the main line caused by the misoperation of the bypass valve.

[0030] Maintaining this state requires continuous monitoring of the unit's operating conditions through a real-time monitoring system. This ensures that when the unit has no load adjustment requirements and all system operating parameters are within a stable range, the fully open state of the main feedwater flow regulation components and the closed state of the flow regulation bypass are always maintained. This allows the feedwater system to operate in optimal condition to support the normal operation of the unit, reducing energy loss from the core link of feedwater delivery and ensuring the economical operation level of the unit during normal operation.

[0031] Step 103: In response to the unit load adjustment, the flow regulation bypass is activated and its feedwater flow is regulated; wherein, when the feedwater flow of the flow regulation bypass is adjusted to the maximum value but still cannot meet the load adjustment requirements, the flow regulation component of the main feedwater line is regulated to reduce the opening degree, thereby increasing the total feedwater flow through the original feedwater bypass and the flow regulation bypass.

[0032] When a load adjustment demand is detected in the unit, the flow regulation bypass is immediately activated, and the feedwater flow is adjusted according to the actual load adjustment needs. This operation is the core adjustment link that relies on the feedwater bypass to improve the unit's load response rate. It can adapt to changes in feedwater supply demand caused by changes in unit load by precisely adjusting the bypass feedwater flow. Activating the flow regulation bypass requires opening the isolation valve and regulating valve on the bypass. Subsequently, based on the specific magnitude of the unit load adjustment, the opening of the regulating valve on the flow regulation bypass is continuously adjusted to achieve precise control of the bypass feedwater flow, ensuring that the feedwater output of the flow regulation bypass always matches the real-time feedwater demand during the unit load adjustment process.

[0033] If the bypass water flow rate reaches the maximum design value after the regulating valve of the flow regulating bypass is fully open, and still cannot meet the current load regulation water demand of the unit, the flow regulating component of the main water supply line is adjusted. By gradually reducing the opening of this component, the water flow resistance of the main water supply line is increased, and some of the water in the main water supply line is diverted to the original water supply bypass and the flow regulating bypass, thereby increasing the total water supply flow of the two bypasses and ensuring that the bypass water supply can match the actual load regulation needs of the unit.

[0034] This tiered control method prioritizes adjusting the feedwater flow rate through the flow regulation bypass, only adjusting the main feedwater components after the bypass regulation capacity reaches its limit. This reduces the frequency of operation of the original feedwater bypass valves, preventing leakage problems caused by frequent operation, and also makes the feedwater flow rate adjustment process more stable and precise. It prevents sudden flow changes from impacting the stable operation of the unit's steam-water system and high-pressure heater, ensuring the stability of feedwater supply during unit load regulation.

[0035] In some embodiments, the step of activating the flow regulation bypass and regulating its feedwater flow in response to the unit load adjustment includes: The water flow rate of the flow regulation bypass is controlled by a series-connected shut-off component and a flow regulation component configured based on the flow regulation bypass.

[0036] When the unit experiences load regulation needs, thus activating the flow regulation bypass and controlling its feedwater flow, the entire process relies on the series-connected shut-off components and flow regulation components configured within the flow regulation bypass. This achieves precise and controllable regulation of the feedwater flow in the flow regulation bypass. These two core components are arranged in series on the feedwater delivery channel of the flow regulation bypass, forming an orderly control hierarchy. This ensures that the adjustment of the bypass feedwater flow combines operational safety with precise regulation. During specific operation, the series-connected shut-off components must first be opened to a fully open state, establishing an unobstructed basic channel for feedwater flow within the flow regulation bypass. As the fundamental device for controlling the flow regulation bypass, the fully open state of the shut-off components ensures that no additional flow resistance is generated in the bypass channel, providing stable feedwater flow conditions for subsequent precise flow regulation.

[0037] After the shut-off component is fully opened, the opening degree of the series-connected flow regulating component is adjusted according to the real-time feedwater demand of the unit load regulation. This component can be flexibly adjusted within the range of fully closed to fully open according to actual needs, thereby achieving continuous and precise control of the feedwater flow of the flow regulating bypass, allowing the feedwater flow output from the bypass to dynamically match the real-time demand during the unit load change process. The series arrangement allows the two components to perform their respective functions: the shut-off component is specifically responsible for the on / off control of the bypass, while the flow regulating component is specifically responsible for the precise regulation of the flow. This avoids the operational losses and regulation errors caused by a single component simultaneously undertaking both on / off and regulation functions. At the same time, when the bypass is not in operation, the complete shutdown of the shut-off component further ensures the sealing performance of the bypass, preventing feedwater leakage, and balancing the accuracy of flow regulation with the economic operation of the entire feedwater system.

[0038] In some embodiments, the flow regulating component of the main water supply line is a regulating valve, the shut-off component of the flow regulating bypass is an isolation valve, and the flow regulating component of the flow regulating bypass is a regulating valve.

[0039] In the process of regulating the feedwater flow of the flow regulation bypass by relying on the series shut-off components and flow regulation components, and regulating the opening degree of the flow regulation components of the main feedwater line, the flow regulation components set in the main feedwater line are regulating valves, the shut-off components configured in the flow regulation bypass are isolation valves, and the flow regulation components of the flow regulation bypass are also regulating valves. The targeted configuration of various valves is highly consistent with the flow regulation requirements of the feedwater system, which can make the feedwater flow adjustment during the unit load regulation process more accurate and operable, and adapt to the actual operation requirements of the unit load response rate improvement.

[0040] The regulating valve on the main feedwater line, as the core flow control device, possesses continuous and precise opening adjustment capabilities. From its fully open state, it can gradually reduce its opening according to the actual load adjustment needs of the unit, precisely controlling the feedwater flow in the main line. This smoothly diverts feedwater from the main line to the original feedwater bypass and flow regulation bypass, preventing sudden changes in main line flow from impacting the stable operation of the unit's steam-water system and high-pressure heater. The isolation valve on the flow regulation bypass, as a dedicated shut-off component for bypass on / off control, features reliable opening and closing action and excellent sealing performance. When fully open, it provides an unobstructed path for feedwater flow in the bypass, laying the foundation for subsequent flow regulation. When fully closed, it completely cuts off the feedwater passage in the bypass, effectively preventing feedwater leakage and ensuring the economical operation of the feedwater system when the bypass is not in operation.

[0041] As the core flow regulation device of the bypass, the regulating valve of the flow regulation bypass can achieve continuous fine adjustment of the opening degree. It can accurately control the bypass feedwater flow according to the real-time demand of unit load regulation within the range of fully closed to fully open. After forming a series connection with the isolation valve, the on-off control of the flow regulation bypass and the flow regulation form a clear operation level, making the flow regulation of the bypass more stable. The reasonable configuration of various valves makes the regulation operation of the entire water supply system more in line with the operating conditions of unit load regulation, and improves the overall regulation efficiency.

[0042] In some embodiments, the flow-passing component of the original water supply bypass is a three-way valve.

[0043] In some embodiments, the step of keeping the flow regulation components of the main feedwater line fully open and shutting off the flow regulation bypass in response to normal unit operation includes: In response to the normal operating state of the unit, the shut-off component and the flow regulation component of the flow regulation bypass are closed.

[0044] When the unit is in normal operation, the operation of keeping the flow regulation components of the main feedwater line fully open and shutting off the flow regulation bypass is performed. Specifically, the shut-off components of the flow regulation bypass and the flow regulation components are completely closed. This operation is a key feedwater system control method to adapt to the unit's normal no-load regulation needs. It can completely cut off the feedwater flow path of the flow regulation bypass from a structural perspective, ensuring the feedwater system's delivery efficiency and operating economy during normal unit operation.

[0045] Keeping the flow regulation components of the main feedwater line fully open allows for smooth feedwater delivery along the main line without additional throttling, minimizing main line flow resistance and precisely matching the regular feedwater supply needs of the high-pressure heater and unit steam-water system, ensuring the feedwater delivery is always in optimal operating condition. Simultaneously closing the shut-off components of the flow regulation bypass and the flow regulation components creates a double-seal shut-off effect, completely eliminating feedwater leakage or ineffective diversion in the flow regulation bypass. This avoids potential sealing hazards caused by closing a single component, preventing feedwater loss, and also prevents interference with the stable delivery of main line feedwater due to accidental flow through the bypass valve.

[0046] By fully closing the two core components of the flow regulation bypass, the bypass remains in a completely non-operating, sealed state, reducing unnecessary valve movements and effectively extending the service life of related bypass valves. The entire process relies on the unit's real-time monitoring system to continuously monitor equipment status, ensuring that during normal unit operation, the fully open state of the main feedwater flow regulation components and the fully closed state of the flow regulation bypass shut-off components and flow regulation components are consistently maintained. This allows all feedwater to be transported along the main line, controlling energy loss at the core of feedwater transport and maintaining the economical level of normal unit operation.
