[0051] The stability and quality of load regulation transition of hydro-turbine generator sets are directly related to the safety of the power grid and the coordination of power sources. In order to ensure the stability of the power grid frequency and the balance of power, the power grid dispatching department issues target load regulation instructions to the hydropower plant computer monitoring system through the automatic power generation control system.

[0052] At present, the speed governor of the hydro-turbine generator set needs to be adjusted under different water heads, so the accuracy of water level measurement is required to be high. At present, the water head parameters are obtained by manually reading the water level scale, which is inefficient and has large errors. In addition, in the scheme of using water level sensors to detect the water level of hydropower stations, since the sensors cannot obtain information from the measurement site, the back-end operating system cannot directly obtain information from the measurement site and cannot display the on-site situation. Correspondingly, the back-end cannot remotely control the water level sensors at the measurement site, and the convenience of water level measurement cannot be guaranteed.

[0062] In this embodiment, Figure 1 The example of including four speed regulators is used for explanation. In fact, this embodiment does not limit the specific number of speed regulators. In this embodiment, a logical operation module is built into the camera device to obtain initial water level data according to the water level image collected by the camera device. The logical operation module can refer to the existing processor 60 that extracts key information based on the picture, which is the existing processor 60. In this embodiment, the water inlet front module 20 is used to convert the initial water inlet water level data obtained by the water inlet camera device 10 into water inlet water level data in a transmission format, so as to facilitate data transmission to the back end. Correspondingly, the tailwater front module 40 can refer to the description of the above-mentioned water inlet front module 20. In this embodiment, the rear module 50 is used to receive the above-mentioned water inlet water level data and tailwater water level data, and convert the water level data in the transmission format into the initial water inlet water level data and initial tailwater water level data that are easy to identify by the processor 60, and transmit them to the speed regulator 70 after the logical operation of the processor 60. This embodiment does not limit the specific connection method between each module and device, as long as a stable communication connection is guaranteed, thereby ensuring stable data transmission. It should be noted that, in this embodiment, the water inlet camera device 10, the water inlet front module 20, the tailwater camera device 30 and the tailwater front module 40 are respectively arranged in the water level measurement areas of the water inlet and the tailwater, while the processor 60 and the rear module 50 can be arranged in the rear end factory building.

[0063] It should be further noted that the specific number of cameras for collecting water level images of the water inlet in the water inlet camera device 10 is not limited in this embodiment, and accordingly, the specific number of cameras for collecting water level images of the tailwater inlet in the tailwater camera device 30 is also not limited in this embodiment. For example, each camera device may include 1 camera, or each camera device may also include 2 cameras, or each camera device may also include 3 or more cameras.

[0064] Furthermore, in order to improve the accuracy of water level measurement and reduce the complexity of the initial water level data obtained by the camera device according to the collected water level image, it is possible to refer to Figure 2 , Figure 2The structural schematic diagram of a water inlet water gauge provided at the water inlet water level monitoring point provided by the embodiment of the utility model. The above-mentioned hydro-generator speed governor 70 regulating system may also include a water inlet water gauge 80 provided at the water inlet water level monitoring point, and a tailwater water gauge provided at the tailwater water level monitoring point.

By setting the water inlet water gauge 80 at the water inlet water level monitoring point and the tailwater water gauge at the tailwater water level monitoring point, on the one hand, the water inlet camera device 10 or the tailwater camera device 30 can directly obtain the image of the water level measured by the water gauge, and then identify the water level information of the monitoring point, thereby reducing the recognition complexity. On the other hand, by setting the water gauge at the water level monitoring point, it is convenient for the operator to obtain the water level information of the water level monitoring point on site, and the water level information of the water level monitoring point obtained on site according to the water gauge is verified with the water level data of the water level monitoring point obtained by the camera device through collection and analysis, thereby improving the accuracy of the camera device obtaining the water level data of the monitoring point according to the water level image collected at the monitoring point. In this embodiment, the above-mentioned water level monitoring points include the positions respectively set at the water inlet and the tailwater, where the water level information needs to be obtained.

At the same time, the above-mentioned water inlet front module 20 and tailwater front module 40 need to convert the digital signals of the water inlet water level data and the tailwater water level data into optical signals respectively, and the water inlet rear unit 51 and the tailwater rear unit 52 need to convert the optical signals of the water inlet water level data and the tailwater water level data back into digital signals respectively, for the processor 60 to perform logical processing.

[0074] Furthermore, in order to improve the convenience and accuracy of the water inlet camera device 10 and the tailrace camera device 30 in collecting water level images of monitoring points at night, the water inlet camera device 10 and the tailrace camera device 30 can be set to be infrared camera devices.

[0075] In the present embodiment, by using the water inlet camera device 10 and the tailwater camera device 30 as infrared camera devices, the accuracy and convenience of the camera devices in collecting water level images at night can be improved.

[0076] Further, in order to improve the flexibility of adjusting the position of the camera device, reference may be made to Figure 4 , Figure 4 The schematic diagram of the structure of a water inlet camera device 10 provided by an embodiment of the utility model.

In addition, the embodiment of the utility model uses the water inlet pre-processing unit 21 to average the multiple water inlet water level data acquired by the multiple water inlet cameras 11, and uses the water inlet pre-conversion unit 22 to transmit the average processed initial water inlet water level average data to the rear module 50, and uses the tailwater pre-processing unit 41 to average the multiple tailwater water level data acquired by the multiple tailwater cameras 31, and uses the tailwater pre-conversion unit 42 to transmit the average processed initial tailwater water level average data to the rear module 50, in the transmission When transmitting water level data, only the average of multiple water level data currently obtained is transmitted, and there is no need to send all water level data obtained by multiple cameras to the processor 60, which reduces the cost of data transmission and avoids the disorder caused by transmitting multiple water level data at the same time, thereby improving the accuracy of adjustment of the speed regulator 70; by setting each water inlet camera 11 to correspond to a water inlet and each tailwater camera 31 to correspond to a tailwater water gauge, while improving the accuracy of water level data acquisition, the number of camera settings can be reduced to ensure the system operation cost.
