PRS-7012 Visualized operation and maintenance main station system
Product Description
Scope of Application
Technical Features/Advantages
The uniform data platform and technology of main operation and maintenance station based on cluster technology can provide a network-based centralized and clustered data platform access interface. Each application module can be deployed on a single machine or in a distributed way according to service requirements, and the engineering implementation is also simpler. In the meantime, the division of modules is reasonable, and the structure is simple and clear, which is more conducive to system expansion and maintenance while improving the reliability of product integration.
The remote inspection technology can be employed to receive station inspection report and provide visualized presentation of inspection results, which supports remote trigger inspection. In this way, the efficiency of inspection work is improved, and transition of inspection method from station-based to remote inspection can be realized.
The power grid fault analysis technique can be used to carry out overall analysis and display of all protection actions in the event of power grid faults, including action briefing and power grid fault analysis report.
The remote diagnosis technique can be adopted to receive intelligent diagnosis report from station in real time, and professional intelligent diagnosis and analysis results and suggestions can be provided.
It supports online calling and retrieval of model files and general files in the plant and station, which greatly reduces the configuration workload in main station.
