[0063] See also Figure 2 and Figure 3 : Collect the real-time operation data 13 and operation data 12 of the target thermal power unit 1, and update them to the thermal power unit database; at the same time, obtain the grid frequency detection data corresponding to the grid to which the target thermal power unit is connected, and update them to the grid database;

[0070] See also Figure 1 and Figure 4 :When the grid frequency monitoring data exceeds the grid frequency floating threshold, the grid frequency amplitude difference is obtained, based on the grid fixed frequency value, the load compensation amount, the load compensation amount reference value and the optimal load compensation amount are obtained according to the grid frequency amplitude difference, and the primary frequency regulation compensation factor is obtained according to the 12 sets of operating data of the target thermal power unit and the optimal load compensation amount, and then the grid load frequency is regulated according to the primary frequency regulation compensation factor.

[0071] See also Figure 5 and Figure 1 : The frequency of the power grid is determined by the power generation and the power load. When the power generation is equal to the power load, the power grid frequency is stable; when the power generation is greater than the power load, the power grid frequency increases; when the power generation is less than the power load, the power grid frequency decreases;

Secondly, by adding a processing backup module 26, the processed data can be stored in time, which can effectively prevent data loss. Through the intelligent frequency modulation simulation method, the adverse effects of frequency modulation on the quality of the generator set can be avoided, and the safe and stable operation of the power grid can be guaranteed. Secondly, in the simulation process, the processed data can be compared with the required data, and the error value between the data can be seen more clearly and intuitively.

[0079] Second embodiment:

[0080] See also Figure 1 , Figure 6 and Figure 7 , and also includes a relay station 4;

[0081] The relay station 4 includes a transceiver bandpass filter 41 and a first power supply 42. The transceiver bandpass filter 41 is electrically connected to a first antenna 43 and a judgment module 44 through a wire. The judgment module 44 is electrically connected to an interference module 45 through a wire. The acquisition module 8 is electrically connected to a first database 47 through a wire. The first database 47 is electrically connected to a storage module A48 through a wire. The outer side of the relay station 4 is also electrically connected to a frequency selection module 46.

[0082] See also Figure 6 : The acquisition module 8 inputs the collected data into the first database 47. At this time, the original data will be quickly stored by the storage module A48, and then the collected data will enter the interior of the relay station 4 and be remotely sent through the first antenna 43;

[0083] In addition, in order to ensure the stability of the frequency band of data transmission during use, the user needs to select a frequency suitable for the current environment in the frequency selection module 46, and the selected frequency is processed by the transceiver bandpass filter 41;

[0084] At this time, if other interference frequencies are generated on site, the judgment module 44 will compare the required frequency with the interference frequency, and the interference module 45 will perform interference processing on the interference frequency.

[0085] The transceiver bandpass filter 41 , the judgment module 44 and the interference module 45 are electrically connected in series, and the acquisition module 8 , the first database 47 and the relay station 4 are electrically connected in series.

[0086] The switch 5 includes a data classification module 51, a second power supply 54 and a second antenna 55. The data classification module 51 is electrically connected to the data integration module 52 via a wire, the data integration module 52 is electrically connected to the second database 53 via a wire, and the second antenna 55 is electrically connected to the remote data transmitter 56 via a wire.

[0087] The data classification module 51 , the data integration module 52 and the second database 53 are electrically connected in series.

[0088] See also Figure 7 The remote data signal transmitted by the above-mentioned relay station 4 is received by the second antenna 55 in the switch 5. The data classification module 51 inside the switch 5 classifies and processes the data of many thermal power unit bodies 1, and then integrates the data through the data integration module 52 and sends it to the second database 53. Then the processed data is transmitted to the central processing station 7 through the remote data transmitting terminal 56.

[0089] This embodiment: Compared with the traditional design, this case is designed with a relay station 4 and a switch 5. Such a design is equivalent to adding two separate base stations in the data transmission process. At the same time, the relay station 4 can independently save and process the most original and authentic data collected on site, so it is convenient for users to collect original data. At the same time, an independent interference module 45 is designed to form a wireless connection with only one frequency band on site. When other interfering frequency bands appear, interference processing will be performed to ensure the stability and security of the remote link.

[0090] Third embodiment:

[0091] See also Figure 2 and Figure 8The ballast module 6 includes a main power supply terminal 61, the main power supply terminal 61 is electrically connected to a voltage detection module 62 through a wire, the voltage detection module 62 is electrically connected to a voltage monitoring module 63 through a wire, and the voltage monitoring module 63 is electrically connected to a circuit breaker 64, a ballast 65 and a voltage indicator light 66 through a wire;

[0092] The ballast 65 and the virtual simulation module 3 are electrically connected in series, and a loop is formed between the main power supply terminal 61 , the voltage detection module 62 , the voltage monitoring module 63 and the circuit breaker 64 .

[0093] See also Figure 8 : The ballast module 6 is installed between the virtual simulation module 3 and the main power supply terminal 61, so the power supply of the entire virtual simulation module 3 is realized through the main power supply terminal 61. Therefore, when the main power supply terminal 61 enters the voltage detection module 62 first, the voltage detection module 62 detects the voltage of the main power supply terminal 61 in real time, and then enters the voltage monitoring module 63 after detection. It can be seen that the voltage monitoring module 63 is distributed in a stepped manner, and the voltage decreases from left to right. If the voltage of the main power supply terminal 61 at this time is very large and reaches the threshold, the circuit breaker 64 will be started to cut off the main power supply terminal 61;

[0094] If the voltage is not within the threshold value, the ballast 65 will stabilize the voltage at a suitable voltage value, and then the current will enter the virtual analog module 3.

[0095] This embodiment: Corresponding to the traditional direct connection design, this case adds a ballast module 6 and sets an independent voltage monitoring module 63. Because surges may occur at the main power supply terminal 61, excessive voltage impacting the virtual simulation module 3 may cause simulation failure. Therefore, when the threshold is reached, the main power supply terminal 61 will be directly cut off. Surge voltage data that does not reach the threshold will be processed by the ballast 65 to ensure that the virtual simulation module 3 can be in a stable working environment for a long time, avoiding damage to the virtual simulation module 3 due to surge voltage impact.

[0096] Please refer to Figures 1 to 8 The working principle of the intelligent frequency regulation optimization control system based on thermal power units provided by the present invention is as follows:

[0097] Step S1: collect the real-time operation data 13 and operation data 12 of the target thermal power unit 1, and update them to the thermal power unit database; at the same time, obtain the grid frequency detection data corresponding to the grid to which the target thermal power unit is connected, and update them to the grid database;

[0098] The second switching module 23 transmits the data from the acquisition end to the first adder 27, and then enters the second adder 24, and the load instruction also enters the first adder 27 through the dynamic corrector 22, and the frequency difference signal enters the second adder 24 through the second switching module 23, and finally the integrated and processed primary frequency modulation data is imported into the virtual simulation module 3 through the PID regulator 25, and the processed data will be stored in the processing backup module 26;

[0099] Step S2: The selection module 33 enters various types of thermal power units, and then the internal CPU 32 will identify and store them. At this time, the processed data entered by the processing module 2 and the required data are entered into the comparison module 34 for comparison processing, and the error value and other system materials are compared. The data after accurate comparison will enter the simulation display screen 31 for simulation. If the deviation error of the data is large, the data will return to the processing module 2 for reprocessing;

[0100] Step S3: The user needs to select a frequency suitable for the current environment in the frequency selection module 46, and the selected frequency is processed by the transceiver bandpass filter 41;

[0101] At this time, if other interference frequencies are generated on site, the judgment module 44 will compare the required frequency with the interference frequency, and the interference module 45 will perform interference processing on the interference frequency;

[0102] The remote data signal transmitted by the relay station 4 is received by the second antenna 55 in the switch 5. The data classification module 51 inside the switch 5 classifies and processes the data of many thermal power unit bodies 1, and then integrates the data through the data integration module 52 and sends it to the second database 53. The processed data is then transmitted to the central processing station 7 through the remote data transmitting terminal 56.

[0103] Step S4: the main power terminal 61 will first enter the voltage detection module 62, and the voltage detection module 62 will detect the voltage of the main power terminal 61 in real time, and then enter the voltage monitoring module 63 after detection. It can be seen that the voltage monitoring module 63 is distributed in a step-by-step manner, and the voltage decreases from left to right. If the voltage of the main power terminal 61 at this time is very large and reaches the threshold, the circuit breaker 64 will be started to cut off the main power terminal 61;

[0104] If the voltage is not at the threshold, the ballast 65 will stabilize the voltage at a suitable voltage value, and then the current will enter the virtual simulation module 3;

[0105] Step S5: Obtain a primary frequency regulation compensation factor according to the target thermal power unit's operating data set 12 and the optimal load compensation amount, then perform grid load frequency regulation according to the primary frequency regulation compensation factor, and finally achieve frequency regulation compensation for the thermal power unit.
