[0002] With the continuous development of the national economy, the power consumption is increasing, and our electrical equipment has higher and higher requirements for the grid voltage. Although the country invests a lot of money in grid transformation every year, in my country's urban and rural power grids, most lines have too large power supply radius, small wire diameter, large load time fluctuations, etc. When the power consumption is too large, it will cause the grid voltage to be too low, and the electrical equipment will be in a low-voltage operation state, causing serious hazards such as motor burnout, dim lights, increased line losses, reduced output of power transmission and transformation equipment, voltage collapse, and even large-scale power outages. When the line load is relatively reduced, it often leads to high voltage. Therefore, solving the problem of large voltage fluctuations and unqualified voltage at the end of the power supply line has always been an important issue of concern to the power supply department.
[0003] Conventional autotransformer voltage regulators can also achieve the effect of increasing the terminal voltage, but their disadvantages are also obvious. They have large losses, large size, and heavy weight. In applications, they are often used in conjunction with simple control methods such as contactors or compound switches to control the taps. Due to the limitations of mechanical switches, their lifespan and response speed are greatly reduced. Moreover, traditional terminal voltage stabilization devices often only focus on voltage stability regulation and lack real-time positioning functions, which brings many inconveniences to troubleshooting and device management.

[0028] This device tracks the voltage changes at the end of the line in real time. The controller 1 quickly and automatically controls the buck-boost unit 7 according to its built-in end voltage stabilization control strategy to perform buck-boost actions according to the real-time voltage level at the end of the power supply line, thereby stabilizing the voltage at the end of the line within the qualified range specified by national standards.
[0029] Controller 1, line voltage and current detection module 2, network communication module 3, GPS positioning module 4, human-computer interaction unit 5, high-power thyristor module 6 and buck-boost unit 7 are connected in series in the power supply line.

The controller 1 uses a 32-bit ARM MCU as the core processor.
[0030] The GPS positioning module 4 determines the current position of the device by receiving specific signals transmitted by multiple satellites. These signals include information such as satellite positions and timestamps. After receiving the signals, the chip in the GPS positioning module 4 calculates the longitude, latitude and altitude of the device through triangulation. After calculating the position information, the GPS positioning module 4 converts these data into a highly readable format and outputs them to the controller 1 and displays them on the human-computer interaction unit 5.

Each satellite will transmit its own position and time information. Through cross-verification of signals from multiple satellites, a more accurate positioning result can be obtained; data output: the calculated position information is output to the device through the serial port of the control circuit.
