Description

Technical Field

[0002] In remote mountainous areas, border areas, high-altitude plateaus, and overseas islands and reefs, the complex terrain and changeable climate restrict the construction and operation of ground communication networks, and the microgrid groups in these areas have gaps and blind spots in information communication. The integrated space-ground communication network, which is supported by satellite Internet, has become a new solution for communication services for remote microgrid groups with its advantages of "low cost, large bandwidth, and low latency". At the same time, the use of satellite communication technology can overcome terrain obstacles and provide stable and wide-area communication services for remote microgrid groups, effectively reducing communication costs and eliminating communication blind spots. Therefore, the integrated space-ground communication network has become an important guarantee for data collection and monitoring, scheduling and control, intelligence and automation of microgrid groups.

[0003] At the same time, there are various noise influences on the large scale of the integrated space-ground communication network. Among them, the most significant influence on the communication of remote microgrid groups is the atmospheric noise caused by the influence of the atmosphere, the rainfall noise due to weather phenomena such as rain and fog, the cosmic noise from the hot gas in outer space and the matter in outer space, and the internal noise generated inside the receiver. Among them, the internal noise can be effectively reduced through shielding measures and temperature control. Considering the Ku and Ka communication frequency bands commonly used in the integrated space-ground communication network, the influence of atmospheric noise and rainfall noise is the most prominent. Under the influence of noise, the control signal transmission of the microgrid group in the integrated space-ground communication network is interfered, resulting in the common control methods having adverse consequences such as reduced control accuracy and reduced system robustness.

[0034] S2, ground sensors collect electrical information of the microgrid group and transmit the electrical information to the ground controller through the integrated space-ground communication network. The electrical information of the microgrid group is usually obtained by various ground sensors in the microgrid group, such as the frequency and active power of each unit. The microgrid group will set up a ground control terminal, and the control terminal will transmit the information to the ground controller through the integrated space-ground communication network (including satellite). The ground controller is usually far away from the microgrid group for remote monitoring.

[0035] S3, the ground controller compares the electrical information with the preset information and obtains the electrical error , thereby obtaining the signal distortion caused by noise interference and the error caused by signal distortion, providing basic data for subsequent adaptive control.

[0036] S4: The ground controller obtains the first correction parameter according to the electrical error value. and the second correction parameter , and Both parameters change with time t. They are time variables, not fixed values, so they can be expressed as functions of changes in time t.

[0037] S5, the ground controller sets the first correction parameter and the second correction parameter And electrical error The input and output signal model is used to obtain an updated output signal, thereby adaptively feedback adjusting the output signal to reduce signal distortion caused by noise interference.

[0038] S6, the ground controller sends the updated output signal to the microgrid group through the integrated space-ground communication network. Specifically, the ground controller sends the output signal to the control terminal of the microgrid group through the integrated space-ground communication network (including satellite), and the updated output signal is sent, so that the microgrid group can be remotely and accurately controlled, and the satellite is used to realize the accurate and rapid interactive transmission of information between the ground controller and the microgrid group. It can be understood that after receiving the updated output signal, the control terminal of the microgrid group adjusts and controls each unit of the microgrid group, and after the adjustment and control are completed, the electrical information will be collected again and fed back to the ground controller, and then return to step S2 to determine the adjustment effect.

The specific steps include collecting electrical information of the microgrid group, calculating electrical errors, and obtaining correction parameters according to the error value, thereby updating the output signal. This adaptive adjustment mechanism improves the robustness and control accuracy of the system in a noisy environment. By comparing the electrical information with the preset information, obtaining the electrical error, and adjusting the control parameters according to the error value, it can effectively cope with changes in environmental noise, improve the robustness of the system, and reduce the reduction of control accuracy and the decline of system performance. It can collect and process the electrical information of the microgrid group in real time, and make adjustments based on real-time errors to ensure the accuracy and timeliness of the output signal of the ground controller, thereby improving the operating efficiency and stability of the microgrid group.

The ground sensors are used to collect electrical information of the microgrid group. The ground control terminal receives the information collected by the ground sensors and transmits the electrical information to the ground controller through the integrated space-ground communication network.
