Description

Technical Field

[0001] This invention relates to the field of generator control technology, specifically to a method for automatic adjustment of generator power. Background Technology

[0002] Waste heat power generation uses waste heat steam to drive a steam turbine to generate electricity. The power generation is adjusted manually according to the pressure. When the amount of waste heat steam increases and the pressure rises, the main valve is opened manually. When the amount of waste heat steam decreases and the pressure drops, the main valve is closed manually to adjust the power generation.

[0003] Because waste heat power generation uses the waste heat from the flue gas of the smelting furnace, the steam volume fluctuates greatly, resulting in frequent manual operation of the power generation load, high labor intensity, and delayed adjustments, which affects the "three-impulse" control of the boiler drum water level and poses a safety risk of boiler drum overpressure. Summary of the Invention

[0004] To solve the above-mentioned technical problems, a method for automatic adjustment of generator power is provided. This technical solution solves the problem that the waste heat power generation uses the waste heat of flue gas from the smelting furnace, which causes large fluctuations in steam volume, resulting in frequent manual operation of the power generation load, high labor intensity, and delayed adjustment, affecting the "three-impulse" control of the boiler drum water level and posing a safety risk of boiler drum overpressure.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A method for automatically adjusting generator power includes:

[0007] Obtain the current operating power requirement of the generator;

[0008] Based on the current operating power demand of the generator, the standard value of the steam pressure in front of the main valve is determined by analysis.

[0009] Determine the dead zone threshold for main valve steam pressure regulation based on the standard value of the main valve steam pressure.

[0010] Real-time monitoring of the steam pressure in front of the main valve, obtaining the real-time value of the steam pressure in front of the main valve;

[0011] The difference between the real-time value of the main valve steam pressure and the standard value of the main valve steam pressure is taken as the pressure deviation.

[0012] Determine if the pressure deviation is greater than the dead zone threshold for the main valve steam pressure regulation. If yes, trigger the action condition; otherwise, do not trigger the action condition.

[0013] If the condition is determined to be triggered, it is determined whether the real-time value of the main valve steam pressure is greater than the standard value of the main valve steam pressure. If so, the output pulse increases the load and controls the main valve opening to increase. If not, the output pulse decreases the load and controls the main valve opening to decrease.

[0014] Preferably, the step of analyzing and determining the standard value of the main valve steam pressure based on the current operating power demand of the generator specifically includes:

[0015] Within the allowable range of the main valve inlet steam pressure, set several sample values ​​of the main valve inlet steam pressure;

[0016] The main valve inlet steam pressure regulation system is used to make the main valve inlet steam pressure reach the sample value of each main valve inlet steam pressure, and the generator output power corresponding to each main valve inlet steam pressure sample value is recorded.

[0017] Plot the main valve steam pressure sample value minus generator output power coordinates in a two-dimensional rectangular coordinate system, using the main valve steam pressure sample value as the horizontal axis and the generator output power as the vertical axis.

[0018] Based on several main valve inlet steam pressure sample values ​​and generator output power coordinate points, a function of main valve inlet steam pressure sample values ​​and generator output power is fitted by function fitting method.

[0019] Substitute the current operating power demand of the generator into the main valve inlet steam pressure sample value - generator output power function to obtain the corresponding main valve inlet steam pressure standard value.

[0020] Preferably, the function fitting method is linear fitting, and the main valve inlet steam pressure sample value - generator output power function is specifically:

[0021]

[0022] In the formula, y is the current operating power demand of the generator, x is the standard value of the main valve steam pressure corresponding to the current operating power demand of the generator being y, k and b are function parameters, and x i Let y be the sample value of the steam pressure before the i-th main valve. i This represents the generator output power corresponding to the sample value of the steam pressure before the i-th main valve.

[0023] Preferably, determining the dead zone threshold for main valve pre-vapor pressure regulation based on the standard value of the main valve pre-vapor pressure specifically includes:

[0024] Historical monitoring values ​​of the main valve inlet steam pressure are obtained, and the data are analyzed to determine the normal operating deviation rate of the main valve inlet steam pressure.

[0025] The dead zone threshold for main valve steam pressure regulation is obtained by multiplying the standard value of the main valve steam pressure in front by the normal operating deviation rate of the main valve steam pressure in front.

[0026] Preferably, the analysis of historical monitoring data on the main valve inlet steam pressure to determine the normal operating deviation rate of the main valve inlet steam pressure specifically includes:

[0027] Based on the historical monitoring data of the main valve steam pressure, the historical deviation rate of the steam pressure corresponding to each historical monitoring data of the main valve steam pressure is calculated to obtain the historical deviation rate data of the steam pressure.

[0028] Outliers in the historical steam pressure deviation rate data are removed to obtain the historical steam pressure standard deviation rate data.

[0029] The historical standard deviation rate of steam pressure that appears most frequently in the historical standard deviation rate data is selected as the highest frequency historical standard deviation rate.

[0030] The maximum value in the historical standard deviation rate data of steam pressure is selected as the worst historical standard deviation rate;

[0031] The minimum value in the historical standard deviation rate data of steam pressure is selected as the optimal historical standard deviation rate.

[0032] Based on the highest frequency historical standard deviation rate, the worst historical standard deviation rate, and the best historical standard deviation rate, the normal operation deviation rate of the steam pressure before the main valve is calculated using the standard deviation calculation formula.

[0033] Preferably, the formula for calculating the standard deviation is as follows:

[0034]

[0035] In the formula, X0 is the normal operating deviation rate of the steam pressure before the main valve. X1 is the average of all historical standard deviation rates for steam pressure, X2 is the worst historical standard deviation rate, and X3 is the best historical standard deviation rate.

[0036] Preferably, the step of removing outliers from the historical steam pressure deviation rate data to obtain the historical steam pressure standard deviation rate data specifically includes:

[0037] Calculate the mean and standard deviation of all historical steam pressure deviation data;

[0038] Based on the average and standard deviation of historical steam pressure deviation rate data, an outlier determination inequality is constructed based on the Grubbs criterion.

[0039] Substitute each historical steam pressure deviation rate into the outlier determination inequality and determine whether it is satisfied. If it is, the historical steam pressure deviation rate is an outlier; otherwise, the historical steam pressure deviation rate is not an outlier.

[0040] Preferably, the step of constructing an outlier determination inequality based on the average and standard deviation of historical steam pressure deviation data specifically includes:

[0041] Determine a detection level;

[0042] Based on the total number and detection level of historical steam pressure deviation rate data, anomaly judgment thresholds are determined according to the Grubbs standard.

[0043] Based on the anomaly detection threshold, an anomaly detection inequality is constructed;

[0044] The outlier determination inequality is as follows:

[0045]

[0046] In the formula, X j ' is the historical deviation rate of the j-th steam pressure, is the average value of the historical steam pressure deviation rate data, S is the standard deviation of the historical steam pressure deviation rate data, and bpn is the anomaly detection threshold.

[0047] Preferably, the detection level ranges from 0.01 to 0.1.

[0048] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0049] This invention proposes a method for automatic generator power adjustment. Based on historical generator operation data, it performs intelligent analysis and learning. Through the development and application of an automatic power supply synchronization and automatic load adjustment control system, it reduces steam pressure fluctuations in waste heat boilers, eliminates the problem of "three-impulse" control caused by pressure fluctuations, reduces the safety risk of boiler drum overpressure, and improves the inherent safety of the equipment.

[0057] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0058] Reference Figure 1 As shown, a method for automatic adjustment of generator power includes:

[0059] Obtain the current operating power requirement of the generator;

[0060] Based on the current operating power demand of the generator, the standard value of the steam pressure in front of the main valve is determined by analysis.

[0061] Determine the dead zone threshold for main valve steam pressure regulation based on the standard value of the main valve steam pressure.

[0062] Real-time monitoring of the steam pressure in front of the main valve, obtaining the real-time value of the steam pressure in front of the main valve;

[0063] The difference between the real-time value of the main valve steam pressure and the standard value of the main valve steam pressure is taken as the pressure deviation.

[0064] Determine if the pressure deviation is greater than the dead zone threshold for the main valve steam pressure regulation. If yes, trigger the action condition; otherwise, do not trigger the action condition.

[0065] If the condition is determined to be triggered, it is determined whether the real-time value of the main valve steam pressure is greater than the standard value of the main valve steam pressure. If so, the output pulse increases the load and controls the main valve opening to increase. If not, the output pulse decreases the load and controls the main valve opening to decrease.

[0066] This solution uses intelligent analysis and learning based on historical generator operation data. Through the development and application of an automatic power supply synchronization and automatic load adjustment control system, it reduces steam pressure fluctuations in the waste heat boiler, eliminates the problem of "three-impulse" control caused by pressure fluctuations, reduces the safety risk of boiler drum overpressure, improves the inherent safety of the equipment, and at the same time reduces the labor intensity of workers and solves the problem of lag in manual operation.

[0067] Reference Figure 2 As shown, based on the generator's current operating power demand, the standard value of the main valve steam pressure is specifically determined as follows:

[0068] Within the allowable range of the main valve inlet steam pressure, set several sample values ​​of the main valve inlet steam pressure;

[0069] The main valve inlet steam pressure regulation system is used to make the main valve inlet steam pressure reach the sample value of each main valve inlet steam pressure, and the generator output power corresponding to each main valve inlet steam pressure sample value is recorded.

[0070] Plot the main valve steam pressure sample value minus generator output power coordinates in a two-dimensional rectangular coordinate system, using the main valve steam pressure sample value as the horizontal axis and the generator output power as the vertical axis.

[0071] Based on several main valve inlet steam pressure sample values ​​and generator output power coordinate points, a function of main valve inlet steam pressure sample values ​​and generator output power is fitted by function fitting method.

[0072] Substitute the current operating power demand of the generator into the main valve inlet steam pressure sample value - generator output power function to obtain the corresponding main valve inlet steam pressure standard value.

[0073] In some preferred embodiments, the function fitting method is specifically linear fitting, and the function of main valve inlet steam pressure sample value - generator output power is specifically:

[0074]

[0075] In the formula, y is the current operating power demand of the generator, x is the standard value of the main valve steam pressure corresponding to the current operating power demand of the generator being y, k and b are function parameters, and x i Let y be the sample value of the steam pressure before the i-th main valve. i This represents the generator output power corresponding to the sample value of the steam pressure before the i-th main valve.

[0076] In this scheme, by comprehensively fitting and analyzing the inherent mathematical relationship between steam pressure and generator power, when operating, only the desired generator operating power needs to be input. Based on the sample value of the steam pressure in front of the main valve - the generator output power function, the standard value of the steam pressure in front of the main valve can be automatically determined, thereby realizing the standardized control setting of the steam pressure in front of the main valve.

[0077] Reference Figure 3 As shown, based on the standard value of the main valve inlet vapor pressure, the specific steps to determine the main valve inlet vapor pressure control dead zone threshold include:

[0078] Historical monitoring values ​​of the main valve inlet steam pressure are obtained, and the data are analyzed to determine the normal operating deviation rate of the main valve inlet steam pressure.

[0079] The dead zone threshold for main valve steam pressure regulation is obtained by multiplying the standard value of the main valve steam pressure in front by the normal operating deviation rate of the main valve steam pressure in front.

[0080] To reduce the number of valve operations and prevent frequent valve actuation, a "dead zone" triggering limit condition was added to the program's logic control. When the fluctuation deviation is within the set range, no adjustment control is performed.

[0081] Reference Figure 4 As shown, based on the analysis of historical monitoring data of the main valve inlet steam pressure, the specific normal operation deviation rate of the main valve inlet steam pressure is determined as follows:

[0082] Based on the historical monitoring data of the main valve steam pressure, the historical deviation rate of the steam pressure corresponding to each historical monitoring data of the main valve steam pressure is calculated to obtain the historical deviation rate data of the steam pressure.

[0083] Outliers in the historical steam pressure deviation rate data are removed to obtain the historical steam pressure standard deviation rate data.

[0084] The historical standard deviation rate of steam pressure that appears most frequently in the historical standard deviation rate data is selected as the highest frequency historical standard deviation rate.

[0085] The maximum value in the historical standard deviation rate data of steam pressure is selected as the worst historical standard deviation rate;

[0086] The minimum value in the historical standard deviation rate data of steam pressure is selected as the optimal historical standard deviation rate.

[0087] Based on the highest frequency historical standard deviation rate, the worst historical standard deviation rate, and the best historical standard deviation rate, the normal operation deviation rate of the steam pressure before the main valve is calculated using the standard deviation calculation formula.

[0088] The formula for calculating standard deviation is as follows:

[0089]

[0090] In the formula, X0 is the normal operating deviation rate of the steam pressure before the main valve. X1 is the average of all historical standard deviation rates for steam pressure, X2 is the worst historical standard deviation rate, and X3 is the best historical standard deviation rate.

[0091] Understandably, the highest historical standard deviation rate, the worst historical standard deviation rate, and the best historical standard deviation rate represent three typical operating states during the normal operation of the steam system. In this scheme, the average of the comprehensive deviation rates under the three typical operating states during the normal operation of the steam system is used to calculate the normal operating deviation rate of the steam pressure before the main valve during the normal operation of the steam system. This normal operating deviation rate can effectively represent the standard pressure fluctuation state of the steam pressure before the main valve under normal operating conditions. When the fluctuation deviation range of the steam pressure before the main valve is less than the normal operating deviation rate, it can be determined that the fluctuation of the steam pressure before the main valve is in a normal state and no adjustment control is required. This allows for fine-grained control and adjustment of the steam pressure before the main valve.

[0092] Reference Figure 5 As shown, outliers in the historical steam pressure deviation rate data are removed to obtain the historical steam pressure standard deviation rate data, which specifically includes:

[0093] Calculate the mean and standard deviation of all historical steam pressure deviation data;

[0094] Based on the average and standard deviation of historical steam pressure deviation rate data, an outlier determination inequality is constructed based on the Grubbs criterion.

[0095] Substitute each historical steam pressure deviation rate into the outlier determination inequality and determine whether it is satisfied. If it is, the historical steam pressure deviation rate is an outlier; otherwise, the historical steam pressure deviation rate is not an outlier.

[0096] Reference Figure 6 As shown, based on the average and standard deviation of historical steam pressure deviation data, the outlier determination inequality constructed based on the Grubbs criterion specifically includes:

[0097] A detection level is determined, with the value ranging from 0.01 to 0.1. In some preferred embodiments, the detection level is set to 0.05, which can effectively retain a sufficient amount of valid data while taking into account the accuracy of outlier detection.

[0098] Based on the total number and detection level of historical steam pressure deviation rate data, anomaly judgment thresholds are determined according to the Grubbs standard.

[0099] Based on the anomaly detection threshold, an anomaly detection inequality is constructed;

[0100] The outlier determination inequality is as follows:

[0101]

[0102] In the formula, X j ' is the historical deviation rate of the j-th steam pressure, is the average value of the historical steam pressure deviation rate data, S is the standard deviation of the historical steam pressure deviation rate data, and bpn is the anomaly detection threshold.

[0103] Understandably, during normal operation of the steam system, the fluctuation of the steam pressure before the main valve should conform to a normal distribution. Based on this, this solution uses the Grubbs criterion to retain the effective data within the fluctuation range that conforms to a normal distribution in the historical steam pressure deviation rate. Based on the above effective data, the normal operation deviation rate of the steam pressure before the main valve is calculated. This effectively ensures that the calculated normal operation deviation rate of the steam pressure before the main valve can accurately reflect the normal fluctuation of the steam pressure before the main valve. Based on this normal operation deviation rate, a dead zone threshold is set, which can effectively ensure the accurate identification of normal pressure when triggering limiting conditions, and realize precise intelligent adjustment and control of the main valve opening.

[0104] Based on the above-mentioned invention concept of automatic generator power regulation method, the specific software design is as follows: Figure 7 As shown:

[0105] By detecting the steam pressure before the turbine's main valve and comparing the detected value with the set value, the DCS control system simulates manual operation and automatically outputs load increase or decrease switching pulse signals, which are then used to adjust the main valve opening via a 505 controller. Low inlet pressure results in a load decrease output, while high inlet pressure results in a load increase output.

[0106] The human-machine interface has an "automatic / manual" selection button. It detects the steam pressure in front of the main valve and calculates the difference with the set value. The difference is compared with the action conditions. If the detected value is higher than the set value and the adjustment conditions are met, a pulse is output to increase the load. If the detected value is lower than the set value and the adjustment conditions are met, a pulse is output to decrease the load. The pulse output length and interval time are adjusted to simulate the manual operation time. The adjustment speed is controlled according to the rate of change.

[0107] Meanwhile, to reduce the number of valve actions and prevent frequent valve operation, a "dead zone" triggering restriction condition was added to the program's logic control. When the fluctuation deviation is within the set range, no adjustment control is performed.

[0108] In summary, the advantages of this invention are as follows: through the development and application of the automatic power supply synchronization and automatic load adjustment control system, the opening degree of the main valve is controlled by using switching quantities, which can reduce the labor intensity of workers and solve the problem of lag in manual operation.

[0109] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
