Description

Technical Field

[0001] This document relates to the field of condenser cooling water volume control technology, and in particular to an energy-saving optimization control method, equipment and medium for condenser cooling water volume. Background Technology

[0002] The control of condenser cooling water flow rate directly affects the economics of thermal power units: increasing the cooling water flow rate can reduce unit back pressure and heat consumption, but it will also increase the power consumption of circulating water pumps. Therefore, there exists an optimal cooling water flow rate that minimizes the sum of these two factors.

[0003] The existing frequency converter control scheme has the following shortcomings: (1) The control target is singular and heat consumption and power consumption are not taken as the overall optimization object; (2) The "one-to-two" frequency converter has "three-to-two switching" operation, which has high safety risk; (3) The frequency converter lacks systematic reliability design and has a high failure rate; (4) The control algorithm has slow response and poor adaptability.

[0004] Therefore, how to achieve precise regulation of cooling water flow through optimized control strategies without modifying the circulating water pump is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] According to embodiments of the present invention, an energy-saving optimization control method, device, and medium for condenser cooling water volume are provided, aiming to solve the above-mentioned problems.

[0006] According to an embodiment of the present invention, an energy-saving optimization control method for condenser cooling water volume is provided, comprising: Obtain the real-time load parameters and cooling water inlet temperature parameters of the unit; Based on the load parameters and the temperature parameters, the optimal cooling water flow rate is determined by gradually increasing or decreasing the flow rate. The operating status of the circulating water pump is controlled according to the optimal cooling water flow rate. The optimal cooling water flow rate is the flow rate that minimizes the sum of the change in unit heat consumption and the change in circulating water pump power consumption.

[0007] According to an embodiment of the present invention, an electronic device is provided, comprising: Processor; and, A memory is configured to store computer-executable instructions, which, when executed, cause the processor to implement the steps of the energy-saving optimization control method for condenser cooling water volume described above.

[0008] This invention aims to minimize the sum of changes in unit heat consumption and circulating water pump power consumption. It precisely determines the optimal cooling water flow rate through a step-by-step flow adjustment method, avoiding heat and power imbalances caused by improper flow regulation. A control scheme with one frequency converter corresponding to one circulating water pump and automatic bypass switching is employed, avoiding the complex switching operations required for a single frequency converter to drive multiple pumps, thus reducing operational safety risks. Furthermore, measures such as configuring the frequency converter capacity with a 1.25 times margin, redundant power unit design, and automatic switching in case of bypass switch failure improve system reliability. A combined strategy of low-load single-pump frequency conversion and high-load parallel operation of power frequency and frequency converter, along with a two-layer architecture combining model predictive control and adaptive control, achieves accurate response and stable control under all operating conditions. In addition, an independent cooling system with the circulating water header as the water source is configured for the frequency converter, prioritizing the frequency converter's cooling needs when adjusting the cooling water flow rate, ensuring stable operation of the frequency converter in high-temperature and dusty environments.

Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this document.

[0014] Method Implementation Examples According to an embodiment of the present invention, an energy-saving optimization control method for condenser cooling water volume is provided. This method is implemented without changing the original circulating water pump and its supporting motor foundation, motor and circulating water pump installation location. The method improves the frequency conversion control of the circulating water pump motor by adding a high-voltage frequency converter and a matching electrical system to achieve electronic frequency conversion continuous speed regulation.

[0015] Figure 1 This is a flowchart of the energy-saving optimization control method for condenser cooling water volume according to an embodiment of the present invention, as shown below. Figure 1 As shown, the energy-saving optimization control method for condenser cooling water volume according to an embodiment of the present invention specifically includes: S1. Obtain the real-time load parameters and cooling water inlet temperature parameters of the unit; S1 specifically includes: The unit's DCS control system collects the unit's power generation load, condenser heat load, and main steam flow as real-time load parameters. The condenser cooling water inlet temperature is acquired by a high-precision platinum resistance temperature transmitter, and after digital filtering and outlier removal, stable and reliable cooling water inlet temperature parameters are obtained. The above load and temperature parameters are uploaded synchronously to the optimization controller as input for calculating the optimal cooling water flow rate.

[0016] S2. Determine the optimal cooling water flow rate by stepping up or down the flow rate based on the load parameters and the temperature parameters. The optimal cooling water flow rate is the flow rate that minimizes the sum of the changes in unit heat consumption and the changes in circulating water pump power consumption. Under constant cooling water inlet temperature and unit load, the condenser pressure changes with the cooling water flow rate. Specifically, as the cooling water flow rate increases, heat exchange in the condenser is enhanced, the unit back pressure decreases, the turbine's work capacity increases, and the unit's heat consumption (coal consumption) decreases accordingly. However, at the same time, the power consumption of the circulating water pump increases with the flow rate. When the increase in cooling water flow rate is small, the decrease in heat consumption is greater than the increase in pump power consumption, and the total energy consumption decreases. When the cooling water flow rate continues to increase beyond a certain critical point, the increase in pump power consumption will exceed the decrease in heat consumption, and the total energy consumption begins to rise. Therefore, the total energy consumption is lowest at this critical point, and the cooling water flow rate corresponding to this critical point is the optimal cooling water flow rate.

[0017] Furthermore, under the condition that the cooling water inlet temperature and unit load are constant, the condenser pressure changes with the cooling water flow rate. When the cooling water flow rate increases, the unit back pressure decreases and the unit heat consumption decreases, but the power consumption of the circulating water pump increases at the same time. When the cooling water flow rate increases too much, the increase in the power consumption of the circulating water pump will offset the decrease in the unit heat consumption.

[0018] Furthermore, the determination of the optimal cooling water flow rate through a step-by-step increase / decrease method specifically includes: Based on the current cooling water flow rate, a flow rate increase operation is performed according to a preset step size. The preset step size is pre-calibrated based on the unit capacity and circulating water pump characteristics. A step size that is too small will result in an excessively long optimization time, while a step size that is too large may cause the optimal flow rate point to be missed. Preferably, the step size is set to 1% to 5% of the rated flow rate of the circulating water pump.

[0019] After each flow rate increase operation, the changes in unit heat consumption and circulating water pump power consumption caused by the flow rate increase are calculated. The change in unit heat consumption is calculated by converting the change in condenser pressure after the flow rate increase into a heat consumption change value based on the mapping relationship between condenser pressure and unit heat consumption. The change in circulating water pump power consumption is calculated by converting the change in flow rate after the flow rate increase into a power consumption change value based on the flow rate-power characteristic curve of the circulating water pump.

[0020] When the decrease in heat consumption indicated by the change in heat consumption is greater than the increase in power consumption indicated by the change in power consumption, it indicates that the economic benefits of increasing the flow rate are greater than the costs incurred, and the next flow rate increase operation is performed. When the heat loss reduction value is less than the power consumption increase value, it indicates that increasing the flow rate is no longer economical, and continuing to increase the flow rate will lead to an increase in total loss. Therefore, the flow rate increase operation is stopped, and the cooling water flow rate before this flow rate increase operation is used as the candidate flow rate. After stopping the flow increase operation, a flow decrease operation is performed based on the candidate flow rate, following a preset step size, and the changes in heat consumption and circulating water pump power consumption are recalculated. This flow decrease operation is used to correct for potential overshooting issues during the flow increase phase. Since the stopping condition during the step-by-step increase is when the heat consumption reduction value is first less than the power consumption increase value, the optimal flow point may lie between the flow rate before and after this increase operation. Therefore, a tentative decrease is needed from the candidate flow rate in the opposite direction to approach the true optimal flow point.

[0021] When the increase in heat loss due to reducing flow rate is less than the decrease in power consumption, it indicates that the heat loss due to reducing flow rate is less than the power consumption saved, and the next flow rate reduction operation will continue. When the increase in heat loss is greater than the decrease in power consumption, it indicates that continuing to reduce the flow rate will cause heat loss to exceed power savings. Therefore, the flow rate reduction operation is stopped, and the cooling water flow rate before this flow rate reduction operation is taken as the optimal cooling water flow rate.

[0022] S3. Controlling the operating state of the circulating water pump according to the optimal cooling water flow rate. S3 specifically includes: controlling the operating state of the circulating water pump according to the optimal cooling water flow rate is performed without changing the original location and connection relationship of the circulating water pump and its associated motor. Specifically, this includes: When the real-time load of the unit is lower than the preset load threshold, it indicates that the output of a single circulating water pump can meet the cooling requirements of the unit. A single circulating water pump is operated in a variable frequency mode, and the cooling water flow rate is changed by adjusting the speed of the single circulating water pump. The load threshold is pre-calibrated based on the unit's rated load and the rated flow rate of the circulating water pump, and is typically set to 50% to 70% of the unit's rated load. When the unit load is lower than this threshold, the single variable frequency pump can operate in its high-efficiency range, and flow matching is achieved by adjusting the speed, avoiding the start-up and shutdown losses and throttling losses of the fixed frequency pump.

[0023] When the real-time load of the unit is higher than the load threshold, it indicates that the output of a single circulating water pump can no longer meet the cooling demand of the unit. Multiple circulating water pumps are connected in parallel, with at least one circulating water pump operating at a fixed speed in power frequency mode as the base pump and at least one circulating water pump operating in variable frequency mode as the regulating pump. The cooling water flow rate is changed by adjusting the speed of the variable frequency pump. In parallel operation mode, the fixed-frequency pump bears the basic flow load, while the variable-frequency pump bears the flow regulation load. The fixed-frequency pump operates at its rated condition with the highest efficiency; the variable-frequency pump achieves continuous and precise control of the total flow through speed regulation, meeting the dynamic adjustment requirements under varying load conditions.

[0024] The start / stop combination and number allocation of the fixed frequency pump and the variable frequency pump are determined in real time by the controller based on the current total cooling water flow demand and the maximum allowable output frequency of the frequency converter.

[0025] Specifically, when the required total cooling water flow is small, the controller prioritizes starting one fixed-frequency pump. When the required flow exceeds the rated flow of a single fixed-frequency pump, the controller starts a second fixed-frequency pump. When the required flow further increases and all fixed-frequency pumps are already in operation, a variable-frequency pump is then activated to supplement the flow and finely adjust it. Simultaneously, the controller monitors the inverter's output frequency in real time. When the inverter frequency approaches the maximum allowable output frequency, it indicates that the current variable-frequency pump is nearing full load. At this point, the controller starts the next fixed-frequency or variable-frequency pump to share the flow load, preventing the inverter from operating at its limit frequency for extended periods, which could lead to overheating or reduced lifespan.

[0026] In the mode of parallel operation of the multiple circulating water pumps: Prioritize starting the mains frequency pump to meet the foundation cooling water flow requirements; If the cooling water flow is still insufficient after the fixed frequency pump is put into operation, then the variable frequency pump is put into operation and started at the lowest frequency. The cooling water flow rate is increased by gradually increasing the frequency of the variable frequency pump until the optimal cooling water flow rate is reached.

[0027] Furthermore, variable frequency speed regulation of circulating water pumps faces three major technical challenges in actual operation: insufficient control precision, slow response speed, and weak system stability, which directly affect the cooling water flow regulation effect and the economic efficiency of unit operation.

[0028] To address the issue of insufficient control precision, the solution employs a PID closed-loop precision control algorithm. Using real-time cooling water flow and inverter output frequency as feedback parameters, the algorithm dynamically corrects the control output by online adaptive tuning of the proportional, integral, and derivative coefficients. This eliminates steady-state errors and dynamic overshoot, ensuring that the cooling water flow accurately tracks the optimal setpoint and fundamentally improving flow regulation precision.

[0029] To address the issue of lag in response speed, this invention introduces a model predictive control (MPC) method. Based on historical operating data of the unit, real-time load, and cooling water temperature, a variable frequency speed regulation prediction model is established. This model predicts frequency change trends and flow regulation needs 1 to 3 control cycles in advance, proactively adjusting the inverter output frequency to achieve millisecond-level fast response. This avoids unit back pressure fluctuations and increased energy consumption caused by flow regulation lag, ensuring rapid optimization and stable regulation under varying operating conditions.

[0030] To address the issue of weak system stability, this invention incorporates an adaptive robust control method that monitors key parameters such as ambient temperature and humidity, grid voltage amplitude and harmonics, and pump load current in real time. By identifying the system model and disturbance characteristics online, it dynamically corrects control parameters and output limits, automatically suppressing external interference and internal parameter drift. This ensures the variable frequency system operates stably under all operating conditions and multiple disturbances, eliminating the risk of condenser operation caused by speed regulation failure.

[0031] Furthermore, the circulating water pump is driven by a frequency converter; The frequency converter and the motor are connected by a one-to-one direct electrical connection. The output side of the frequency converter is further equipped with a one-to-one automatic switching operation scheme after the high-voltage frequency conversion modification. The frequency converter capacity is matched with the rated power of the motor and has a 20% capacity margin. The power is configured to be 1.25 times the rated power. The power unit of the frequency converter is equipped with redundant components, so that the frequency converter system will still maintain normal operation when any power unit fails.

[0032] Furthermore, after the high-voltage frequency conversion upgrade, the electrical control mode is a one-to-one automatic switching operation scheme, with the frequency converter capacity matching the rated power of the motor and leaving a 20% capacity margin.

[0033] Furthermore, the frequency converter adopts a voltage source type multilevel topology; The frequency converter is of the high-high type and does not use an output boost form; On the input side, multiplexed rectification cancels out current harmonics. The output voltage waveform is made close to a sine wave by multi-level voltage synthesis on the output side; The inverter does not have an output reactor at its output terminal.

[0034] Furthermore, the total current harmonics and voltage harmonics of the frequency converter are no more than 2%, and the harmonic requirements for grid feedback meet the most stringent requirements of the standard for voltage distortion.

[0035] Furthermore, the transformer efficiency reaches over 98%, the efficiency of the entire frequency converter system reaches over 97% across the entire speed range, and it possesses transformer closing low inrush current technology.

[0036] Furthermore, an independent cooling system is configured for the frequency converter; The cooling system uses a circulating water main pipe as the cooling water source; The cooling system includes a circulating water booster pump and a backwash filter, which are used to maintain the inverter operating within the set temperature and cleanliness range. The minimum flow rate of the circulating water booster pump is not less than 100 m³ / h, and the minimum flow rate of the backwash filter is not less than 120 m³ / h. The circulating water booster pump and the backwash filter are equipped with an electrical control cabinet to achieve remote control.

[0037] When adjusting the cooling water flow rate, priority should be given to ensuring the water flow rate requirements of the inverter cooling system; When the total cooling water flow rate is lower than the preset cooling protection threshold, the frequency reduction rate of the variable frequency pump is limited.

[0038] Furthermore, the internal heat exchange tubes of the water source cooling unit are made of copper tubes with a diameter ≥7 / 9.52mm and a thickness ≥0.35mm, and externally connected with hydrophilic aluminum heat sinks with a thickness ≥0.115mm. The heat sinks are processed into sinusoidal double-wave corrugated fins with a fin spacing ≤2.8mm, and are tightly attached by hydraulic tube expansion to increase heat transfer efficiency, with an expansion pressure ≥120MPa; the U-shaped tubes at both ends of the heat exchanger are arranged in an alternating manner.

[0039] More specifically, the dynamic adjustment in this embodiment of the invention adopts a two-layer control architecture: The upper level aims to achieve the best unit economy and calculates the optimal cooling water flow rate setpoint based on unit load and cooling water inlet temperature; The optimal cooling water flow rate under different loads and different cooling water inlet temperatures is pre-calibrated through offline tests to form an optimized control database; The lower layer uses a combination of model predictive control and adaptive control to ensure that the actual cooling water flow rate tracks the upper layer setpoint. The adaptive control algorithm monitors changes in ambient temperature and power supply voltage in real time and adaptively adjusts control parameters to maintain system stability.

[0040] This invention utilizes a newly added high-voltage frequency converter to replace high and low speeds for precise speed regulation, achieving optimal control of condenser cooling water flow under various load conditions and realizing energy savings under different load segments. The improved frequency conversion of the circulating water pump motor optimizes the economical operation of the cold-end system, resulting in a decrease in average coal consumption for power supply of approximately 0.2 g / (kW·h), saving 660 tons of standard coal annually, and generating coal savings revenue of 678,900 yuan.

[0041] This invention aims to minimize the sum of changes in unit heat consumption and circulating water pump power consumption. It precisely determines the optimal cooling water flow rate through a step-by-step flow adjustment method, avoiding heat and power imbalances caused by improper flow regulation. A control scheme with one frequency converter corresponding to one circulating water pump and automatic bypass switching is employed, avoiding the complex switching operations required for a single frequency converter to drive multiple pumps, thus reducing operational safety risks. Furthermore, measures such as configuring the frequency converter capacity with a 1.25 times margin, redundant power unit design, and automatic switching in case of bypass switch failure improve system reliability. A combined strategy of low-load single-pump frequency conversion and high-load parallel operation of power frequency and frequency converter, along with a two-layer architecture combining model predictive control and adaptive control, achieves accurate response and stable control under all operating conditions. In addition, an independent cooling system with the circulating water header as the water source is configured for the frequency converter, prioritizing the frequency converter's cooling needs when adjusting the cooling water flow rate, ensuring stable operation of the frequency converter in high-temperature and dusty environments.
