Constructing an unmanned Remote Monitoring system, which willPV power stationAll information is uploaded via fiber optic to the centralized control center of IoT Smart Energy Co., Ltd. Each site must be equipped with sufficientData Acquisitiondevices, and the data provided to the remote control system includes but is not limited to:Integrated Automation SystemInverter, box transformer measurement and controlelectricity meterWaiting for device information to achieve data aggregation. The collection device supports Modbus RTU/TCP, CDTIEC101/102/103/104、 DLT645 and other communication Protocol, as well as providing RS485, Ethernet and other related communication interfaces. The station Data Acquisition forwarding device should be configured separatelyCommunication management device， TheZhihuforwarding device provides wireless communication such as 4G/5G and WIFI, as well as Ethernet and RS485 interfaces, which can provide data interfaces for remote centralized control systems. It supports docking with remote centralized control side collection devices or databases through Modbus TCP, IEC104, and other methods such as calling theProtocolhistorical database API interface to achieve data uploading or writing to theReal-timehistorical database. 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, and insist on "security zoning, network dedicated, horizontal isolationVertical authentication”The principle is to ensure the safety of the power monitoring system and pass the 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)
