[0002] In the power system, the stability of generator frequency is one of the key factors to ensure the quality of power supply and safe operation of the system. When the generator frequency deviates from its rated value and exceeds the specified range, if it is not adjusted in time, it may cause damage to power equipment, degradation of power supply quality and even system collapse. Therefore, the automatic adjustment mechanism of generator frequency, especially the primary frequency regulation technology, is particularly important.

[0003] The existing primary frequency modulation technology first converts the speed deviation between the turbine speed signal collected on the DEH system side and the rated speed into a valve opening increment through the primary frequency modulation function of "slip-flow" to adjust the load value of the power grid unit; then, on the CCS system side, the speed deviation is converted into a load setting value increment using the primary frequency modulation function of "slip-power", and the load value of the power grid unit is finely adjusted according to the current load setting value increment, so that the generator frequency is restored to the specified range.

[0004] However, in practical applications, due to the differences in the operating characteristics of power grid units under different load segments, the same primary frequency regulation function cannot achieve the ideal frequency regulation effect under all load segments, especially under the operating conditions of small frequency difference disturbances and large frequency difference disturbances, resulting in the response time, action time and regulation accuracy of the primary frequency regulation failing to meet the specified requirements.

[0026] 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 aid 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. It should be noted that the embodiments of the present disclosure and the features therein may be combined with each other without conflict.

[0027] The following describes the optimization method, device and electronic device of primary frequency modulation according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0028] The present disclosure provides an optimization method device and electronic equipment for primary frequency regulation, the main purpose of which is to solve the technical problem that the same primary frequency regulation function cannot achieve an ideal frequency regulation effect under all load sections due to differences in operating characteristics of power grid units under different load sections, especially under the working conditions of small frequency difference disturbance and large frequency difference disturbance, resulting in the response time, action time and regulation accuracy of the primary frequency regulation failing to meet the requirements.

[0029] like Figure 1 As shown, an embodiment of the present disclosure provides a method for optimizing a primary frequency modulation, the method comprising:

[0030] Step 101: Obtain the unit load of the generator set.

[0031] Among them, the unit load can be the workload undertaken by the generator set during operation, usually expressed in power or torque, reflecting the working status and efficiency of the generator set in actual operation; the size of the unit load directly affects the speed and frequency of the generator.

[0032] For the embodiments of the present disclosure, the execution entity may be a distributed control system (DCS).

[0033] like Figure 2 As shown, before obtaining the unit load of the generator set, the distributed control system can first obtain multiple generator frequencies of the generator set, such as Figure 2 The generator frequency input 201 includes the generator frequency 1, the generator frequency 2 and the generator frequency 3, and performs analog quantity optimization processing on multiple generator frequencies, such as the generator frequency 1, the generator frequency 2 and the generator frequency 3 ( Figure 2 Marked as 202), the optimized generator frequency is obtained.

[0034] The analog quantity optimization processing can be to select the median, average, maximum or minimum value as the optimal value from multiple generator frequencies, such as generator frequency 1, generator frequency 2 and generator frequency 3, so as to prevent the control system from making wrong actions when a single signal is abnormal (such as failure, noise interference, etc.). By selecting the optimal value of the three signals, the influence of abnormal signals on the control system can be minimized.

[0035] Specifically, the three frequency input signals can be optimized and selected according to the MODE parameter, and the optimal frequency signal selected according to the input rate RATE value is used as the output result ( Figure 2 The MODE parameter can be used to specify the selection of the median, average, maximum or minimum signal, or the optimal signal calculated according to a certain algorithm, etc. The MODE parameter can be flexibly adjusted according to the actual situation and needs to adapt to different operating conditions and fault conditions.

[0036] For the embodiments of the present disclosure, the optimized generator frequency can be compared with the rated frequency range. If the generator frequency exceeds the rated frequency range, the unit load of the generator set is obtained, and the unit load is used to adjust the power generation power of the generator set so that the generator frequency is restored to the rated frequency range.

[0037] The rated frequency range may be the value of the generator frequency at which the generator can operate continuously under specified normal use and performance conditions.

[0038] Specifically, when the generator frequency is lower than the rated frequency range, that is, the current power generation is insufficient to meet the current power load, the control system can calculate a positive load setting value increment, requiring the unit to increase the load to make up for the power shortage in the power grid, thereby restoring the generator frequency to the rated frequency range. On the contrary, when the generator frequency is higher than the rated frequency range, that is, the power generation exceeds the current power load, the control system can calculate a negative load setting value increment, requiring the unit to reduce the load to reduce the excess power in the power grid, thereby restoring the generator frequency to the rated frequency range.

[0039] Step 102: Determine a corresponding frequency modulation function according to the load size of the unit.

[0040] The frequency regulation function may be different frequency regulation functions designed according to different ranges of the unit load of the generator set, and each frequency regulation function may be used to define how the generator set should adjust its output power according to the change of the generator frequency within the unit load range.

[0041] For the embodiments of the present disclosure, Figure 3 As shown, the load judgment module 301 can be used to monitor and judge the load size of the unit load in real time; the unit load can be judged as the first unit load, the second unit load, the third unit load or the fourth unit load according to the load size, wherein the first unit load is less than the second unit load, the second unit load is less than the third unit load, and the third unit load is less than the fourth unit load. Exemplarily, the load range of the first unit load can be 0-150MW, the load range of the second unit load can be 150-300MW, the load range of the third unit load can be 300-450MW, and the load range of the fourth unit load can be 450-600MW.

[0042] Among them, the first frequency modulation function (i.e. Figure 3-3 02) Corresponding to the load of the first unit, the corresponding relationship can be: -150~-40; -12~-40; -2.1~-4.4; -2~0; 2~0; 2.1~4.4; 12~40; 150~40;

[0043] The second frequency modulation function (i.e. Figure 3-3 03) Corresponding to the load of the second unit, the corresponding relationship can be: -150~-24; -12~-24; -2.1~-4.4; -2~0; 2~0; 2.1~4.4; 12~24; 150~24;

[0044] The third frequency modulation function (i.e. Figure 3-304) Corresponding to the load of the third unit, the corresponding relationship can be: -150~-18; -12~-18; -2.1~-4.4; -2~0; 2~0; 2.1~4.4; 12~18; 150~18;

[0045] The fourth frequency modulation function (i.e. Figure 3-3 05) Corresponding to the load of the fourth unit, the corresponding relationship can be: -150~-8; -12~-8; -2.1~-4.4; -2~0; 2~0; 2.1~4.4; 12~8; 150~8.

[0046] For the embodiments of the present disclosure, Figure 3 As shown, the corresponding frequency modulation function is determined according to the load size of the unit load, which may specifically include:

[0047] When the load of the unit is determined to be the first unit load (i.e. 0-150MW) according to the load size, the first load selector ( Figure 3-3 09) determining the corresponding frequency modulation function as the first frequency modulation function;

[0048] When the load of the unit is determined to be the load of the second unit (i.e. 150-300MW) according to the load size, the second load selector ( Figure 3-3 08) determining the corresponding frequency modulation function as a second frequency modulation function;

[0049] When the load of the unit is determined to be the load of the third unit (i.e. 300-450MW) according to the load size, the third load selector ( Figure 3-3 07) determining the corresponding frequency modulation function as a third frequency modulation function;

[0050] When the load of the unit is determined to be the load of the fourth unit (i.e. 450-600MW) according to the load size, the fourth load selector ( Figure 3-3 06) Determine the corresponding frequency modulation function as the fourth frequency modulation function.

[0051] Among them, Figure 3 As shown, the load selection can be used to output X2 when the input signal SEL is "1" and to output X1 when the input signal SEL is "0".

[0052] For the disclosed embodiment, the primary frequency regulation function of different frequency regulation functions is selected according to the load size of the generator set, so that the output power adjustment strategy of the generator set can be optimized according to different load conditions, so as to achieve the ideal frequency regulation effect under different working conditions, especially under the working conditions of small frequency difference disturbance and large frequency difference disturbance, so that the response time, action time and adjustment accuracy of the primary frequency regulation can meet the specified requirements, thereby improving the stability and efficiency of the power system.

[0053] Step 103: Use the frequency modulation function to adjust the power generated by the generator set so that the generator frequency returns to within the rated frequency range.

[0054] In the embodiment of the present disclosure, in the process of using the frequency modulation function to adjust the power generated by the generator set, in order to achieve rapid response to the generator frequency change (fast action) and slow recovery to the original state (slow return) to avoid excessive impact on the power system, the frequency modulation function can be used to adjust the power generated by the generator set. Figure 4 The rate setting module 403 can determine the power adjustment rate of the generated power according to the actual situation of the generator set, the grid demand and the scheduling requirements to ensure that the frequency regulation effect meets the expectations; in response to the power adjustment rate, the frequency regulation function is used to adjust the generated power of the generator set.

[0055] Among them, the power adjustment rate includes a fast rate and a slow recovery rate. The fast rate can be used to control the adjustment speed of the power generation power of the generator set. The generator set quickly adjusts its output power when the generator frequency changes to quickly respond to the frequency deviation, which helps to reduce the duration of the frequency deviation and thus reduce the impact on the stability of the power grid; the slow recovery rate can be used to control the recovery speed of the power generation power of the generator set. The generator set slowly recovers to its original state after the generator frequency is adjusted to avoid the impact of excessive recovery speed on the power grid, which helps to maintain the stable operation of the power grid.

[0056] Before using the rate setting module 403 to determine the power adjustment rate of the generated power, Figure 4 After the condition judgment module 402 in the generator set judges that the generator set is connected to the grid and the frequency regulation function is put into operation, the rate setting module 403 is started to ensure that the frequency regulation action is not triggered by mistake in the generator set.

[0057] If the conditional judgment module 402 detects that the generator set is in a disconnected state (i.e., disconnected from the power grid) or the primary frequency regulation function is not enabled, the conditional judgment module 402 can cut off the currently set fast action rate and slow return rate to avoid damage to the generator set or the power grid under adverse conditions.

[0058] During the signal recovery period, the slow recovery rate of the signal to recover to the normal value can be achieved by switching the fast rate to the slow recovery rate through the switching module 401 .

[0059] For the embodiment of the present disclosure, after the power generation power of the generator set is adjusted by using the frequency modulation function, the power generation power of the generator set can also be adjusted by using the frequency modulation function. Figure 3The high and low limit module 3010 in the power control module performs power limit on the power generation after power adjustment to keep the power generation power within the target power range, wherein the target power range may be in the range of -40 to 40, so as to prevent the generator set from overloading or generating unstable output, while ensuring the stable operation of the power system.

[0060] In summary, according to a primary frequency modulation optimization method disclosed in the present invention, the unit load of the generator set can be obtained; the corresponding frequency modulation function can be determined according to the load size of the unit load; and the power generation power of the generator set can be adjusted by using the frequency modulation function to restore the generator frequency to the rated frequency range. For the embodiment of the present disclosure, by setting the corresponding frequency modulation function according to the load size of different unit loads, the power generation power of the generator set is adjusted in real time by using the frequency modulation function, so that the ideal frequency modulation effect can be achieved under different working conditions, especially under the working conditions of small frequency difference disturbance and large frequency difference disturbance, so that the response time, action time and adjustment accuracy of the primary frequency modulation can meet the specified requirements.
