Protection Information Management System
Application Scenarios
Applicable to 10 kV distribution switchgear stations, 35 kV and above substations, as well as new energy power plants, petrochemical, rail transit and other industries requiring protection information management systems. The substation completes fault information collection, processing, storage, and transmission to the remote master station system, while the master station performs fault information processing, analysis, publishing, and display functions.
System Composition
    Consists of two parts: protection information master station and substation. The master station system is based on a domestic operating system, supports domestic hardware, and consists of front-end servers, data servers, workstations, etc. The substation system consists of hosts, workstations, and related network communication equipment, with host hardware implemented via embedded devices or servers.
