Benefits
AST 1150system enables to use the existing substation equipment
(telecontrol systems, emergency registration system, emergency
control automatics, relay protection devices and other) without
rework and replacement of component parts. The system interfaces
with existing systems of other vendors via standard data
communications protocols IEC60870-5-101, IEC60870-5-104, Modbus
RTU.
The equipment used in the AST 1150 system provides high
fail-safety, which is proved by its stable work in harsh
environments, including remote unattended sites. Redundant CPUs and
SCADAInfinity servers are available. Manufacturing of all stages of
the system is organized in compliance with the requirements of ISO
9001 standard.
Digital sensors are arranges in separate suspended boxes with
installed heating elements for outdoor use, providing protection
level up to IP65. It reduces the length of measuring chains from
current transformers, which, in turn, increases accuracy of
conducted metering
Operator can access on-line system information from any remote
device via the Internet. The system is protected against
unauthorized access by security and user right authentication
modules of SCADAInfinity.
Remote software configuration of controllers, relay protection
and automatic equipment terminals is available for operations
department, which enables to significantly reduce the time spent on
reconfiguration of substation automation and telemetry
equipment.
AST 1150 system is designed to ensure scalability in hardware
and functionality to adapt to growing customer requirements.
