PKUS SR24 Teleprotection Equipment with Control and monitoring panel

APPLICATION

Functionality

• Teleprotection command transmission via 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,

- Switching on and off of command transmission or/and reception with switches,
- Display on the LEDs for transmitted and received commands,

• Up to 24 transmitted and up to 24 received commands,

• User configurable data rate for command transfer (min. 64 kbps, max. 1984 kbps; up to 8 commands at 64 kbps),

• Less than 10 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,

• operation via one or two line interfaces,

• seamless channel redundancy with 0 milliseconds time for switching from main to redundant channel,

• 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,

• Addressing facility preventing unwanted operation due to accidental channel crossovers in telecom network,

• Compatible with PKUS SKO Teleprotection equipment on channel level,

• 4 relay contacts for each received command,

• Switches for on and off transmission of each command reception of each command (completely for the received command and individually for each of its 4 contact),

• Non-volatile display on the LEDs for transmitted and received commands, alarms and signaling,

• Integrated nonvolatile and not editable event recorder for transmitted and received command, switch positions, alarms, internal and external signaling 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 SR24,

• All events can be saved to not editable file or COMTRADE file,

• IEC 60870-5-101 and IEC 60870-5-104 for SCADA,

• Windows® compatible User Interface Program HMIPanel configuration (on-line and off-line downloadable files) changing the configuration is password protected testing and commissioning,

• The principles of the operation of the PKUS SR24 are patented.

ADVANTAGES

• Transmission time, dependability and security comply with or exceed the requirements of IEC 60834-1 “Teleprotection equipment of power systems. Performance and testing. Part 1. Command systems”,

• PKUS SR24 complies with or exceeds the requirements of Russian and international EMC standards,

• Improving the reliability by eliminating command inputs and outputs, and signal cables between Teleprotection equipment and Control and monitoring panel,

• Continuous monitoring of the connection between Teleprotection equipment and Control and monitoring panel,

• Improving the reliability of the Control and monitoring panels by reducing the number of signal cables and their terminal connections,

• Standard solutions using PKUS SR24 lead to reduced development time the decrease in the number of mistakes in projects lower CAPEX and OPEX,

• Compact overall dimensions of PKUS SR24 allow to avoid problems with the placement of Teleprotection Equipment and Control and monitoring panels at substations.
