Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a microgrid controller. Background Technology

[0002] With the increasing consumption of fossil fuels and growing environmental awareness, renewable energy has received widespread attention. As renewable energy technologies rapidly develop, the scale of grid-connected renewable energy is expanding. Microgrids, as a form of energy utilization, combine distributed power sources, energy storage, and loads into an independent power supply system. This reduces the adverse impact of renewable energy grid connection on the power grid. Microgrids are autonomous systems capable of self-control, protection, and management; they can operate in parallel with the main grid or in isolation. The microgrid controller is the core control device of the microgrid system, requiring multiple external cables to connect it to the loads.

[0003] However, the length of the connecting wires inside the existing microgrid controller is not easy to adjust when connecting to loads, which is not conducive to the routing and standardization of the connecting wires. This can easily lead to messy wiring at the controller interface, which is detrimental to the safety of controller use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a microgrid controller to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a microgrid controller, including a controller internally equipped with various microgrid control elements. One end of the controller has a connecting line that is connected to the microgrid control elements. A contact pressure ring connected to the microgrid control elements is provided between the connecting line and the microgrid control elements. The contact pressure ring is signal-connected to a line stability control module. The line stability control module is signal-connected to a guide roller that drives the connecting line. Both ends of the guide roller are rotatably connected to guide grooves for the connecting line. A clamping plate for clamping and securing the connecting line is fixedly installed inside the guide groove. One end of the guide groove is rotatably connected to a cable tray for arranging the connecting line. Both ends of the cable tray are engaged with clamping blocks located inside the guide groove. One end of the cable tray is provided with an anti-slip strip that rubs against and secures the controller. A manually operated pull groove is provided in the middle of one end of the cable tray.

[0006] Preferably, one end of the controller has a groove for conducting the connecting wires, and the other end of the controller is fixedly mounted with a display screen connected to the microgrid control element. The contact pressure ring includes a pressure sensor fixedly mounted on the bottom of the microgrid control element and a pressure ring that is pressed against the connecting wires. The pressure sensor detects the pressure on the pressure ring.

[0007] The above technical solution involves transmitting signals between the power grid and microgrid control components via a connecting line, enabling the microgrid control components to process and monitor information from the power grid, facilitating stable control of the microgrid. Simultaneously, a pressure sensor detects the pressure between the connecting line and the microgrid control components in real time, and the stability of the connection between the connecting line and the microgrid control components is determined based on the detected pressure. The connecting line can then be adjusted according to the stability of the connection.

The drive motor can rotate in both directions and can drive the connecting line to move inside or outside the controller. The tension of the connecting line and the control element in the controller can be adjusted to ensure the stability of the connection between the connecting line and the control element.
