CK6062 series ring type industrial Ethernet switches used in power dispatching automation system

According to the technical requirements of power dispatching automation system, using open and distributed systems, this system is divided into two parts: The lower-level system and the upper-level system. Lower system complete protection, measurement, control tasks; The upper-level system to complete the monitoring and management tasks. Key equipment (host, data acquisition systems, dispatcher workstations, networks, etc.) systems can be configured with redundant, hot standby mode of operation to ensure the system is running with high reliability and safety checks, system software has a good openness, database provides interactive tools constitute a perfect environment to support a variety of tools for interactive access. System with friendly interface and simple operation. In the system, taking into account the strong support system maintenance tools, and provides remote diagnostic tools, users can get online system maintenance to ensure system maintainability. The system has good scalability, and lay a solid foundation for future system expansion.

System description:

In this scenario, use two front (collection) processor, 2 systems (data) servers SCADA system hot standby; the two dispatcher workstations; a microcomputer composed of EMS energy management workstation; 1 microcomputer composition DTS dispatcher workstation; 1 engineer maintenance station; a laser printer. SCADA can achieve real-time communication with the plant station RTU's. Set the gateway server and the company's management network networking and remote diagnostics. The program uses Shenzhen Comark CK6062 consisting of redundant Ethernet, industrial-grade optical fiber structure, front (collection) processor, system server, dispatcher workstations, engineering stations, EMSstations, DTS workstations working under the redundant network. When one network fails, CK6062 starts redundancy to ensure communications can be done by another network.

As the use of WebAccess SCADA monitoring system, two high-performance pre-processor as a field collection / site monitoring / remote network monitoring, can replace the system host workstation.

Network Structure:

( Figure 1 )
