NSD570 remote protection interface

In order to protect the power system from faults and damage, the remote protection system must transmit command signals in the shortest possible time to selectively remove the faulty portion.
The NSD570 is designed to transmit protection commands over a variety of communication media, such as analog and digital channels for copper, fiber, optical and microwave wireless links, and Ethernet/IP-based communication networks.

Product Details

The commands can be exchanged with protection devices using contact-type input and output hard wiring or "GOOSE" information based on substation networks via IEC 61850. The modular design of the NSD570 offers the greatest possible flexibility and is suitable for all application needs.

Characteristics

— Analog, digital/optical, Ethernet/IP communication connections

— Analog communication route up to 4 independent commands

— Data communication route up to 8 independent commands

— Permission, blocking, and direct trip can be set for each command

— Signal processing for the shortest transmission time

— Fast, reliable and safe

— Continuous channel monitoring, alarm will be available when the channel is unavailable or of poor quality (eg end-to-end delay is too large)

— Integrated event logger and trip count

— User graphical interface for easy operation and maintenance, fully programmable

— Remote monitoring and configuration, including SNMP alerts for NMS communications

— Integrated HMI network element management system, which can monitor and parameterize NSD570 whole network through embedded business channel (EOC)

— Flexible structure: one switch line interface (2-/4- analog line, digital G.703 or V.11/X.21/X.24, 10/100 Mbps Ethernet) One protection interface (up to each system) 4 protection interfaces)

— Optional integrated E1/T1 interface for SDH/SONET multiplexer or optical interface for direct fiber connection and IEEE C37.94 optical to digital multiplexer (short and long-haul SFP versions)

— Transfer up to 8 "GOOSE" messages (multiple substations that can be automatically configured according to IEC 61850 Ed. 2 according to IEC 61850-8-1)

— Optional integrated LAN/Ethernet interface for network-based remote management

— The front panel LED provides status indication, or optional integrated LCD for status display

— 1+1 configuration to protect the communication path failure (no need to repeat the protection interface, the switching time is less than 1ms)

— Cost saving solution for multi-terminal line protection

— Single or redundant power supply
