[0064] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0065] First, the application scenario of the present disclosure is introduced. The present disclosure is applied in a scenario where the operating load of a generator set is in an unstable state. For example, the generator set may be a thermal power unit, and the unstable state may refer to the generator set being in a load increase state or a load decrease state.
[0066] During the production process of a thermal power plant, the low-quality exhaust steam discharged from the low-pressure cylinder of the turbine of the generator set will be cooled by the circulating water in the condenser to obtain condensate. Due to the large difference in the specific volumes of exhaust steam and condensate, a vacuum will be generated during the condensation of the exhaust steam, and the exhaust steam from the low-pressure cylinder is nearly saturated at the initial stage. Therefore, the lower the back pressure, the lower the exhaust temperature.
[0067] The working efficiency of the condenser can be characterized by the back pressure. The lower the back pressure, the higher the working efficiency of the condenser. In other words, when the back pressure is within the normal operating range, the condenser is determined to be operating normally; when the back pressure is outside the normal operating range, the condenser is determined to be operating abnormally. For example, if the back pressure of the condenser is too high (greater than or equal to -70KPa), the condenser will trip, making the generator set unable to continue to produce electricity; if the back pressure of the condenser is too low, the steam at the last stage blade of the turbine will reach the expansion limit. If the back pressure is further reduced, the flow of steam at the last stage blade will become disordered, increasing energy loss, thereby reducing the power generation efficiency of the generator set.
[0068] Since the back pressure of the condenser will affect the working efficiency of the generator set, it is necessary to control the back pressure of the condenser to stabilize the working efficiency of the generator set. Since the cooling effect (i.e., heat absorption capacity) of the circulating water in the circulating water pump on the condensed water will affect the back pressure of the condenser, the back pressure of the condenser can be controlled by adjusting the operating frequency of the circulating water pump. The operating frequency of the circulating water pump is negatively correlated with the back pressure of the condenser, that is, the lower the operating frequency of the circulating water pump, the higher the back pressure of the condenser; the higher the operating frequency of the circulating water pump, the lower the back pressure of the condenser.
[0069] The generator set can be equipped with two circulating water pumps, one of which is variable frequency controlled and can adjust the frequency of the circulating water pump according to the operating conditions of the generator set; the other is industrial frequency controlled and can only adjust the frequency of the circulating water pump to high frequency or low frequency operation, so as to control the condenser back pressure value of the generator set by adjusting the operating frequency of the two circulating water pumps. The two circulating water pumps can be adjusted a limited number of times for long-term seasonal changes, but they cannot respond effectively to changes in the temperature difference between day and night, peak and valley changes in power load, etc.
[0070] In the related art, when the generator set is in non-steady-state operation, the operating conditions of the unit vary greatly, and the operating parameters of the circulating water pump and condenser in the generator set cannot be accurately determined, so that the precise control of the operating frequency of the circulating water pump cannot be achieved, resulting in low working efficiency of the condenser, and then low power generation efficiency of the generator set, leading to waste of resources.
[0071] In order to solve the above problems, the present disclosure provides a control method, device, storage medium and electronic device for a generator set; when the operating load of the generator set is in an unstable state, the current water temperature of the circulating water in the first circulating water pump of the generator set is obtained; the current load and the target load of the generator set are obtained; according to the current water temperature, the current load and the target load, the operating frequency of the first circulating water pump is adjusted; through the above technical scheme, when the operating load of the generator set is in an unstable state, based on the current water temperature of the circulating water pump, the current load and the target load of the generator set, the operating frequency of the circulating water pump can be tracked and adjusted, thereby stabilizing the operating condition of the generator set, realizing precise adjustment of the operating frequency of the circulating water pump, thereby stabilizing the operating condition of the generator set and improving the power generation efficiency of the generator set.
[0072] Figure 1 FIG. 1 is a flow chart showing a method for controlling a generator set according to an exemplary embodiment. Figure 1 As shown, the method may include the following steps.
[0073] S101. When the operating load of a generator set is in an unstable state, obtain the current water temperature of circulating water in a first circulating water pump of the generator set.
[0074] For example, the non-stable state may refer to the generator set being in a load-up state or a load-down state. For example, the generator set may increase or decrease load in response to an AGC instruction.
[0075] For example, the current water temperature of the circulating water in the first circulating water pump of the generator set may be acquired through a sensor, which may be a temperature sensor.
[0076] S102: Obtain the current load and target load of the generator set.
[0077] For example, the current load may be the current operating load of the generator set; the target load may be the load value to which the generator set needs to be adjusted, and the target load may be the load value indicated by the AGC instruction.
[0078] S103: adjusting the operating frequency of the first circulating water pump according to the current water temperature, the current load and the target load.
[0079] In some embodiments, the above S103 may include: increasing the operating frequency of the first circulating water pump by 1 Hz according to the current water temperature, the current load and the target load; or reducing the operating frequency of the first circulating water pump by 1 Hz according to the current water temperature, the current load and the target load.
[0080] When the operating load of the generator set is in an unstable state, the adjustment of the operating frequency of the circulating water pump will have a greater impact on the operating load, so the single adjustment amount is set to a smaller value; and for the frequency adjustment of the circulating water pump, its minimum adjustment unit is 1Hz, so the adjustment value of the operating frequency can be set to 1Hz. In this way, setting the single adjustment amount to a smaller value will not have a significant impact on the overall operation of the generator set, thereby maintaining the stability of the overall operation; and because the single adjustment amount is small, the operating frequency can be adjusted multiple times, thereby achieving precise control of the operating frequency of the circulating water pump and improving the power generation efficiency of the generator set.
[0081] It should be noted that the operating frequency of the circulating water pump is negatively correlated with the back pressure value of the condenser of the generator set; the lower the operating frequency of the circulating water pump, the higher the back pressure of the condenser, and the higher the working efficiency of the generator set; the higher the operating frequency of the circulating water pump, the lower the back pressure of the condenser, and the lower the working efficiency of the generator set.
[0082] Through the above technical solution, when the operating load of the generator set is in a non-steady state, the operating frequency of the circulating water pump can be tracked and adjusted based on the current water temperature of the circulating water pump, the current load of the generator set and the target load, thereby stabilizing the operating condition of the generator set and achieving precise adjustment of the operating frequency of the circulating water pump, thereby stabilizing the operating condition of the generator set and improving the power generation efficiency of the generator set.
[0083] Figure 2 is based on Figure 1 FIG. 1 is a flow chart of a method for controlling a generator set as shown in an exemplary embodiment of the present invention. Figure 2 As shown, the above S103 may include the following steps.
[0084] S1031. Determine a first load corresponding to the current water temperature.
[0085] For example, the first load corresponding to the current water temperature can be determined by a preset corresponding relationship. The preset corresponding relationship can be a corresponding relationship between different water temperatures and different load values; the higher the water temperature, the smaller the load value. For example, the first load corresponding to 15°C is 28.1MW, and the first load corresponding to 10°C is 30MW. In this way, the corresponding load value can be quickly determined based on the corresponding relationship to improve work efficiency.
[0086] It should be noted that the load value of the first load corresponding to the current water temperature may be different when the generator set is in a load-up state and a load-down state. For example, when it is determined that the generator set is in a load-up state, the first target load corresponding to the current water temperature may be determined through a first preset corresponding relationship, and the first target load may be used as the first load. Alternatively, when it is determined that the generator set is in a load-down state, the second target load corresponding to the current water temperature may be determined through a second preset corresponding relationship, and the second target load may be used as the first load.
[0087] For example, the first preset correspondence may refer to the correspondence between different water temperatures and different load values when the generator set is in a load-up state; the second preset correspondence may refer to the correspondence between different water temperatures and different load values when the generator set is in a load-down state. The second target load may be less than the first target load, for example, the second target load may be 0.8 times the first target load. In this way, different correspondences may be set for different operating states of the generator set to improve the accuracy of determining the first load.
[0088] S1032: Determine a second load according to the current load and the target load.
[0089] For example, the difference between the current load and the target load may be used as the second load.
[0090] The current load, that is, the current operating load, refers to the operating load value corresponding to the generator set at the current moment, and is a parameter that can be directly obtained.
[0091] The first load refers to the ideal load value obtained based on the preset corresponding relationship, which is determined from a plurality of preset load values with different numerical values and corresponds to the current water temperature. The plurality of preset load values with different numerical values are ideal load values obtained through experiments based on different water temperatures of the generator set. Since the preset corresponding relationship, i.e., the corresponding relationship between different water temperatures and different load values, is obtained in advance through experiments, the first load can be an ideal load value corresponding to the current water temperature that is quickly determined based on the current water temperature and the preset corresponding relationship.
[0092] The target load refers to the load value that the generator set needs to be adjusted to; during operation, the generator set will receive an AGC instruction, which is a peak-shaving instruction, which is used to instruct the generator set to increase or decrease the current load (i.e., the current operating load) to a certain set value (i.e., the target load). For example, if the AGC instruction instructs the generator set to increase the load, the target load is the load value that the generator set needs to increase to.
[0093] S1033. Adjust the operating frequency of the first circulating water pump according to the first load and the second load.
[0094] In some embodiments, the above S1033 may include: if it is determined that the second load is greater than or equal to the first load, adjusting the operating frequency of the first circulating water pump.
[0095] For example, when it is determined that the second load is greater than or equal to the first load, the operating frequency of the first circulating water pump can be reduced by 1 Hz. In this way, the back pressure of the condenser can be increased, thereby improving the working efficiency of the generator set.
[0096] Figure 3 is based on Figure 2 FIG. 1 is a flow chart of a method for controlling a generator set as shown in an exemplary embodiment of the present invention. Figure 3 As shown, the method may further include the following steps.
[0097] S104: When the operating parameters of the first circulating water pump meet the preset starting conditions, start the second circulating water pump of the generator set, wherein the second circulating water pump is a standby circulating water pump.
[0098] In some embodiments, the operating parameters may include an operating frequency and a coal consumption value; the preset start-up conditions may include: the operating frequency of the first circulating water pump is within a first preset frequency range; or, the coal consumption value of the first circulating water pump is greater than or equal to a first preset coal consumption threshold.
[0099] For example, the first preset frequency range may be within the range of 40-60 Hz, for example, 40 Hz, 45 Hz, 50 Hz or 60 Hz, etc.; the first preset coal consumption threshold may be set by the user and is not limited here.
[0100] In other embodiments, the coal consumption value of the first circulating water pump can be determined by: periodically obtaining a back pressure value corresponding to the first circulating water pump; and determining the coal consumption value based on the back pressure value and a preset coal consumption coefficient.
[0101] For example, the voltage and current of the first circulating water pump may be obtained, and the corresponding back pressure value may be determined according to the voltage and current. The preset coal consumption coefficient may be a constant determined according to the historical operation of the generator set, for example, may be 2.36.
[0102] In some embodiments, the second circulating water pump may include multiple ones; and starting the second circulating water pump of the generator set includes: starting the multiple second circulating water pumps in sequence according to a preset starting sequence. For example, the preset starting sequence can be set by a user and is not limited here.
[0103] Figure 4 is based on Figure 3 FIG. 1 is a flow chart of a method for controlling a generator set as shown in an exemplary embodiment of the present invention. Figure 4 As shown, the method may further include the following steps.
[0104] S105: When the operating parameters of the second circulating water pump meet the preset stop conditions, stop the second circulating water pump.
[0105] In some embodiments, the operating parameters may include an operating frequency and a coal consumption value; the preset stop condition may include: the operating frequency of the second circulating water pump is within a second preset frequency range; or, the coal consumption value of the second circulating water pump is greater than or equal to a second preset coal consumption threshold.
[0106] For example, the second preset frequency range may be within the range of 25-40 Hz, such as 25 Hz, 30 Hz, 53 Hz or 40 Hz, etc.; the second preset coal consumption threshold may be set by the user and is not limited here.
[0107] Figure 5 FIG. 1 is a flow chart showing another method for controlling a generator set according to an exemplary embodiment. Figure 5As shown, the method may include the following steps.
[0108] S501. When the operating load of the generator set is in an unstable state, obtain the current water temperature of the circulating water in the first circulating water pump of the generator set.
[0109] S502: Obtain the current load and target load of the generator set.
[0110] S503: Determine a first load corresponding to the current water temperature.
[0111] S504: Determine a second load according to the current load and the target load.
[0112] S505: When it is determined that the second load is greater than or equal to the first load, adjust the operating frequency of the first circulating water pump.

[0114] Among them, the second circulating water pump is a backup circulating water pump.
