Photovoltaic Power Station Centralized Control Remote Monitoring System Platform - Integrated Automation System, Inverter, Box-type Transformer Measurement and Control, Electric Energy Meter, Modbus RTU/TCP, CDT, IEC 101/102/103/104, DLT645 Communication Management Device, Horizontal Isolation, Vertical Authentication, AGC/AVC
Build an unmanned remote monitoring system to upload all information of the photovoltaic power station to the centralized control center of the Output IoT Smart Energy Co., Ltd. through optical fiber. Each site needs to be equipped with sufficient data acquisition devices to provide data to the remote control system, including but not limited to: integrated automation system, inverters, box transformer measurement and control, energy meters and other equipment information, to achieve data collection. The collection device supports communication protocols such as Modbus RTU/TCP, CDT, IEC101/102/103/104, DLT645, and provides related communication interfaces such as RS485 and Ethernet. The station data collection and forwarding equipment should be equipped with a separate communication management device. The data collection and forwarding equipment provides wireless communication such as 4G/5G, WIFI, as well as Ethernet, RS485 and other interfaces, which can provide data interfaces for remote control systems. It supports docking with remote control side collection devices or databases through protocols such as Modbus TCP, IEC104 or calling real-time historical database API interfaces to achieve data uploading or writing to real-time historical databases. Equipped with remote start stop control for inverters, supporting remote adjustment of active and reactive power.
All communication network equipment involved must be selected from domestic devices, and the operating system must use domestic operating systems such as UNIX. The system must be patched for vulnerabilities and reinforced, and a reinforcement report must be provided. Configure electromagnetic protection cabinets and construct redundant communication channels. The security protection work of the power monitoring system should implement the national information security level protection system, adhere to the relevant requirements of national information security level protection, adhere to the principles of "security zoning, network dedicated, horizontal isolation, and vertical authentication", ensure the security of the power monitoring system, and pass the security evaluation of relevant qualified units. The power grid dispatch data network, comprehensive management network, communication system equipment, and installation deployment must be carried out in accordance with the relevant requirements of the local power grid.
AGC、AVC、 Some configuration requirements for data network communication equipment shall be approved by the power grid company for system access（plan)
