Power distribution master station 1, distribution substation 2, backbone layer communication network 3, and access layer communication network 4.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in the figure, a power distribution automation system disclosed by the utility model includes a power distribution master station 1, a power distribution substation 2, and a power distribution terminal. 2, the distribution substation 2 is connected to the power distribution terminal through the access layer communication network 4, the power distribution terminal includes several FTUs, TTUs or DTUs, the FTUs are connected to the switch on the column, and the TTUs are connected to the power distribution The transformer is connected, and the DTU is connected with the ring network cabinet.

The power distribution terminal includes FTU (Feeder Terminal Unit), TTU (distribution Transformer supervisory Terminal Unit, distribution transformer monitoring terminal) and DTU (Distribution Terminal Unit). Monitoring, complete telemetry, remote control, remote signaling, fault detection functions, provide distribution system operation status and various parameters, that is, information required for monitoring and control, including switch status, power parameters, phase-to-phase fault, ground fault and fault parameters, and Execute the commands issued by the power distribution master station 1, adjust and control the power distribution equipment, and realize the functions of fault location, fault isolation and fast power supply restoration in non-faulty areas.

DTU is installed in the switch station or power distribution place, and has the functions of remote control, remote signaling, telemetry and fault current detection, and is used to convert the data of the ring main unit into IP data or convert the IP data into serial port data for transmission through the wireless communication network .

FTU is an intelligent terminal device installed in the power distribution room or feeder. It can communicate with the remote distribution substation 2, send the operation data of the power distribution equipment to the distribution substation 2, and can also accept the control commands of the distribution substation 2 to control and adjust the power distribution equipment. FTU and RTU have the following differences: FTU is small in size and large in number, and can be placed on the outdoor feeder. High environmental requirements; FTU collects a small amount of data, requires a low communication rate, and requires high reliability; while RTU collects a large amount of data, has a high communication rate, requires high reliability, and has a dedicated channel.

The above are only specific embodiments of the present utility model, but the design concept of the present utility model is not limited thereto. Any insubstantial modification of the utility model using this concept should be an act of violating the protection scope of the utility model.
