Description

Technical Field

[0001] The present invention relates to the technical field of energy networks, and in particular to a regulating device and a method for using a distributed energy network. Background Art

[0002] Distributed energy systems are relative to traditional centralized energy systems. Traditional centralized energy systems use large-capacity equipment and centralized production, then transmit various energy sources to a large number of users over a large area through specialized transmission facilities such as large power grids and large thermal networks. Distributed energy is an energy supply method installed at the user end, which is combined with user loads to form a "point-to-point" energy supply and demand relationship. Among these energy sources, including solar energy and wind energy, microgrids can also integrate with surrounding distributed generation systems to form a broader distributed energy network across campuses and microgrids, further improving energy matching. At this time, by controlling the distributed energy network, energy utilization can be made more efficient and economical.

[0003] When a microgrid's power supply line fails on the main grid side, causing a sudden power outage, it will cause instantaneous charge transfer, causing the adjacent microgrid to collapse and even redistributing the power flow of the entire network. In addition, some electrical points in the distributed energy network, such as simple distributed power generation systems such as rooftop photovoltaics, will change randomly due to factors such as weather. During the operation of a single energy storage unit, it is difficult to automatically disconnect the power between devices, and manual separation operations are required for the equipment that has short-circuited, affecting the safety of the equipment during operation.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original adjustment structure. Summary of the Invention

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a regulating device for a distributed energy network, comprising an energy storage box, an equipment box door hingedly connected to the outside of the energy storage box, and a signal transmitter connected to the wires directly above the energy storage box, a power connection bracket nested on the right side of the energy storage box, and a power plug fixed to the outside of the power connection bracket with bolts, the internal wires of the energy storage box are connected to a rectifier, and the wires directly below the rectifier are connected to the converter, and further comprising: a transformer box, a transformer cable nested on the outside of the transformer cable, and a rod insulator wound around the outside of the transformer cable, The top of the rod-shaped insulator is bolted to a high-voltage electric support; the winding group is installed on the outside of the power connection support, and the outside of the power connection support is nested and connected with a rectangular slide, and the telescopic cylinder is installed inside the energy storage box; the shielding box is bolted to the left and right sides of the transformer box, and the outside of the shielding box is nested and connected with a power connection connector, and the inside of the power connection connector is welded and fixed with a power connection column, the internal wires of the transformer box are connected to the detection unit module, and the internal wires of the transformer box are connected to the voltage panel, and the outer wires of the voltage panel are connected to the common connection box.

[0007] Preferably, the energy storage box and the high-voltage electric support are connected to the rod-shaped insulator through a transformer cable, and the high-voltage electric support and the rod-shaped insulator are perpendicular to each other. The high-voltage electric support transmits sufficient current, which facilitates grid processing of the current.

[0008] Preferably, the power connection bracket and the power connection plug form a sliding structure through a rectangular slide groove and a telescopic cylinder, and the power connection plug and the power connection connector are parallel to each other, and the power connection bracket and the rectangular slide groove are connected by a slider.

[0009] Preferably, the power plug and the power connector form a locking structure through the power post, and the diameter of the power plug is smaller than the diameter of the power connector, and the current is detected and processed through the power plug and the power connector.

[0010] Preferably, the power connector and the power bracket are connected through a winding group, and the longitudinal section of the power bracket is a "C"-shaped structure, and the power bracket is made of polystyrene. The power connector is positioned by the power bracket to avoid equipment short circuit affecting equipment operation.

[0011] Preferably, the detection unit module is electrically connected to the voltage panel and the common connection box respectively, and the detection unit module and the power connector are parallel to each other, and the number of power connectors is 2 groups. The detection unit module is used to control the device to avoid equipment short circuit affecting other devices.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The distributed energy network regulation device is provided with an electrical connection connector and an electrical connection bracket. When a detection unit detects abnormal voltage and current of the tie line, after a fourth preset time delay, the second microgrid disconnects the electrical connection connector in the second microgrid and performs positioning processing on the outer side of the electrical connection connector through the electrical connection bracket. During use, different types of current are controlled to avoid damage to equipment within the energy network caused by excessive changes in the current amplitude of a certain new energy power generation equipment.

[0014] The regulating device of the distributed energy network is provided with a telescopic cylinder and a shielding box. The telescopic cylinder is used to position the outer side of the connecting bracket. During use, the connecting bracket drives the connecting connector to slide horizontally, so that the connecting connector and the connecting plug are positioned to prevent the connecting plug from affecting the safety of equipment operation during the connection and power-off process. The shielding box is used to shield the connection of the equipment connector to ensure the safety of the equipment itself during operation and prevent rainwater from outside from flowing into the inside of the connecting connector and the connecting plug.
