PKUS SKO Teleprotection Equipment

APPLICATION

FUNCTIONALITY

• Teleprotection command transmission via 
• o telecom networks (SDH/PDH, MPLS, etc.) with C37.94 and E1 interfaces
• direct optical fibers (the distance of up to 240 km, the distance may be increased using optical amplifiers)
• CWDM/DWDM systems
• radio links. 

• Up to 16 transmitted and up to 16 received commands,
• User configurable data rate for command transfer (min. 64 kbps, max. 1984 kbps; up to 8 commands at 64 kbps),
• 4.5 ms transmission time at 64 kbps (Dependability of 10-4 and Security of 10-30 in worst case),
• Dual line interface (on request): two electrical E1 (HDB3, G.704) or two optical E1 (CMI, G.704) / C37.94,
• Optical interfaces with SFP transceivers,
• Point-to-point and point-to-multipoint applications via direct optical fibers and communication networks,
• Up to 6 independent duplex links in point-to-multipoint applications via communication networks with cross connection on time slot level of E1,
• Normal and Inverse T-operation for a protection of power lines with T-offs,
• Seamless 1+1 path (primary and secondary paths) protection with switchover time of 0 ms,
• Cyclic (configurable) and Manual (activated by User Interface Program PKUSConvereter) Loop test,
• Addressing facility preventing unwanted operation due to accidental channel crossovers in telecom network,
• Compatible with PKUS SR24 Teleprotection equipment with Control and monitoring panel on channel level,
• Integrated nonvolatile and not editable event recorder for transmitted and received command, alarms and user manipulations with 1 ms time stamps from internal Real Time Clock,
• Optional synchronization of Real Time Clock from IRIG-B input,
• Upload, text and graphical display of all events recoded in PKUS SKO,
• All events can be saved to not editable file or COMTRADE file,
• IEC 60870-5-101, IEC 60870-5-104 and SNMP for SCADA,
• Windows® compatible User Interface Program PKUS Converter
• configuration (on-line and off-line downloadable files)
• changing the configuration is password protected
• testing and commissioning.
