PLC remote centralized monitoring (Intranet penetration)
With the promotion and application of informatization, intellectualization and digitalization in various industries, the data in plants at all levels shall be transmitted to the group's operation management center for unified monitoring and management. PLC data in plants and stations shall be connected to the external network through the Linqi intelligent communication gateway. In the central control room of centralized monitoring, no server or fixed IP is needed to realize on-site PLC data acquisition and control. The SCADA software can directly read the remote site PLC data and form a virtual LAN between the site PLC network and the network cable of the centralized monitoring room through wired, 4G and WIFI. The communication networking application is shown in the figure below.

Internet of Things data on the cloud
In each physical dispersed area, intelligent gateways are installed to realize data collection of intelligent devices in the dispersed area, and the data can be converted into protocols on the Intranet and connected to SCADA system. Meanwhile, the data can be sent to the enterprise's own cloud platform, or such as Alibaba Cloud Internet of Things platform and mobile OneNet platform, which can easily realize the data cloud. Onsite wiring is only required, without on-site debugging. Cloud debugging can be used to realize real-time messages, real-time data, and various serial network tests.

Forward isolation device data transmission
As the new generation of State Grid strengthens the transformation of new energy absorption, more and more new energy distributed power stations are connected to the State Grid. Distributed power stations generally need to be digitized and intelligent, and accept the check and control of owners and intelligent operation and maintenance parties at any time, as well as the dynamic commands of power dispatching and dynamic reports of power quality monitoring from remote master stations. This involves different network systems. The owner end is generally the open Internet, and the photovoltaic operation and maintenance is also generally the private line external network or VPN encrypted external network. The internal production control and power dispatching of the power station belong to the production control of the State grid and have different security levels, so they need to be physically isolated between different security zones.

Photovoltaic power station data access group operation and maintenance center
Photovoltaic grid-connected principle: first meet the local load, the rest of the grid. Local generation, local consumption, avoiding transmission losses (5%). Power station power consumption calculation and power consumption calculation are the key to grid-connected design: power generation curve and local load demand curve should be matched as far as possible, so as to minimize the fluctuation of grid-connected input and reduce the pressure on the absorption capacity of the grid.
