T/JSIA 0002-2023 Data Access Specification for Power Meteorological Public Service Platform

Scope

Main Technical Content: Data Update Frequency: The update frequency of data depends on the access object, collection device, and business application requirements. Archival data is updated as needed when changes occur, while metering data is updated according to the device collection frequency or business application requirements. Example: Typhoon real-time path data is updated hourly, and severe convection forecast data is updated every 5 minutes. 7. Data Access Methods 7.1 Collection Terminal Access Method: Data collected by collection terminals should be transmitted to the platform via dedicated communication channels. 7.2 Data Integration Access Method: 7.2.1 Government Meteorological Department Data Access: Data from government meteorological departments is integrated into the platform via the government intranet through a transit database and transmitted via VPN dedicated lines. 7.2.2 Power Company Intranet System Data Access: Data from power company intranet systems is extracted to a transit database via data retrieval interfaces deployed on the intranet and transmitted to the platform via isolation devices. The interface program should comply with GB/T 36345-2018 and GB/T 38672-2020 standards. 7.2.3 Meteorological Data Service Provider Data Access: Meteorological data service providers access the platform via standard data interfaces in an internet environment. Users without the ability to access the platform's standard interfaces must develop customized data interfaces and convert data to standard models via a unified model conversion agent to enable data access. 8. Data Transmission Models 8.1 Collection Terminal Transmission Model: Modbus RTU, Modbus TCP, and IEC 61850 communication protocols are used for data transmission between metering devices and data gateways. CDT, IEC 60870-5-101, IEC 60870-5-102, IEC 60870-5-103, and IEC 60870-5-104 protocols are used for data transmission between data gateways and the platform. D
