ABB NISA-03 NTAC-02 NTCS04 PCU-03 Pulse Encoder Interface Module

Description

NTAC-02
The step by step part of multiplex transmission technology
The global power system has a great influence on these new communication technologies
Whether the operation can adapt to the strict remote protection system
The performance requirements of are very worrying. especially
Yes, if the communication is dependent on the third party and the communication circuit is not
The business completely controlled by the power system is particularly critical
Note.

In view of the above reasons, when using Ethernet/IP
When the network transmits protection signals
One solution to monitor WAN (wide area
Network) availability and quality of communication circuits, and
Unable to ensure reliable transmission of commands to remote terminals
Alarm to the protection device at the same time.
New generation of innovative solutions for distance protection
Available as a leading long distance NTAC-02 protection solution
ABB has developed a
A series of new interfaces are used to realize the communication through Ethernet
Network/IP network transmission protection signal and remote
Management ｜ 2. Innovative solutions include the following two

– NSD570 Ethernet WAN interface G3LE
– NSD570 LAN management interface G3LM
NSD570 Ethernet WAN interface G3LE
– New line interface supports Ethernet/IP network
Transmit up to 8 simultaneous/independent protection commands

Reliability performance under extreme network conditions
According to IEC 60834-1 standard, digital communication system
Minimum safety requirements for transmission trip command in the system
(called P u c or probability of maloperation) is
Puc < 1E-08。 As per NSD570
The new protocol of

Channel monitoring function continuously monitors quality and availability
Packet switching networks are vulnerable to attacks by various factors
Features have a negative impact on transmission time.
