PRS-7000 SCADA
Product Description
Scope of Application
Technical Features/Advantages
Powerful functions: integrated five-protection, one-key sequence control, VQC, intelligent fault alarm, and intelligent association.
System security: self-dependent and controllable core software and hardware, advanced and reliable.
Great compatibility: service-based access to underlying resources, standard platform services, and modular upper-layer applications.
Secure isolation: the system supports secure isolation between applications and applications/platforms, and strengthens the security of power monitoring system.
Tamper-proof database and one-key safe recovery: it can ensure the storage security of operation and monitoring data.
Hierarchical and optimal dispatching based on underlying resources: this can effectively guarantee rapid response of real-time monitoring services.
Flexible load balancing: this function can improve the service processing capability of system and ensure high reliability of service.
Integrated graphic-mode library: it supports one-key automatic imaging of monitoring screen, which can effectively eliminate omissions caused by manual drawing and improve the imaging efficiency of monitoring screen.
Dynamic expansion of communication protocols: it enables communication access of various monitoring devices in substations in different periods and different scenarios.
Powerful script calculation function: it supports custom configuration of various calculation signal expressions and complex control blocking logic.
