★ Remote motive/group control and coordination terminal:

☞ 4-core 2.0G, 6-channel Gigabit Ethernet port, optional 8-channel RS485/232 interface collection and forwarding

☞ Optional encryption machine, forward isolation, reverse isolation remote motor and group control and coordination terminal to respond to data scheduling instructions, control inverter or data acquisition device, reactive power compensation equipment (including: SVG, reactor, capacitor)

★ Composition of PV dispatching data network:

➢ The group control device interacts with the uplink file of distributed energy resources and securely accesses the forwarding server in the area. Through the E file format, the relevant measurement data of the distributed power generation is sent to the dispatching group control server through the reverse isolation device. After the server parses the measurement data file sent by the secure access area, the relevant data is saved to the common database of the prefecture and county controlled by the local survey, group survey, and group control. These data are used as a reference for the group survey and control program to formulate remote dispatch strategies

➢ When the dispatching server receives the remote adjustment instruction file issued by the AGC server, the program analyzes the remote adjustment instruction file, and formulates the remote adjustment target value of the corresponding distributed power source according to the remote adjustment strategy of dispatching distributed power points and refers to the measurement data sent to the group control group control on the distributed power generation, and generates the remote adjustment instruction file

These remote command files are delivered to the forwarding server in the secure access area through the forward isolation device. The forwarding server in the secure access area receives the remote adjustment command file and parses it. According to the requirements of the instruction document, the remote dispatch command is issued to the distributed power plant station, and the distributed energy plant station receives the command and starts the remote dispatch operation

➢ Dispatching data networks of different scales, generally composed of 2M services and 100M services. The selection of encryption devices with different bandwidths has a great relationship with the cost, and 10M and 100M encryption devices can be selected. Switches and routers also have 10M/100M bandwidth options

➢ Each group of data network equipment is equipped with 1 router, 2 power-specific longitudinal encryption devices, and 2 switches. The router is responsible for data service transmission, two vertical encryption devices are divided into real-time information areas and non-real-time information areas, and one vertical encryption device is equipped with one switch for business processing

The complete set of dispatching data network equipment configuration of the main power network is generally 2 routers, 4 power-specific longitudinal encryption devices, 4 switches, and dual-plane networking
