Advanced Substation Automation System (SAS) For Modern Power Substations

CTR offers a substation automation system based on advanced client-server architecture, designed for monitoring, control, and automation of modern power substations. It works with different network topologies and communication protocols, including IEC 61850.

The system is built on the zenon platform from COPA-DATA, and CTR is a registered partner of the COPA-DATA Partner Community. CTR’s own software, CTR CDZENON, is developed on this platform, giving utilities and industries a reliable, expandable system for supervising their substations.

Substation Automation System

What Is a Substation Automation System?

A substation automation system (SAS) is a set of servers, software, communication networks, and field devices that allow an operator to monitor and control a substation from one location. It collects data from transformers, circuit breakers and feeders. Then show this information to operators and send commands back to the field.

Without automation, staff reads meters and operates switches on site. This is slow and requires people to present. With an SAS the operators have a full picture of the substation in real time. They receive alarms immediately and can take local or remote action.

The basic data flow is:

Field devices → Communication network → SAS servers → Operator stations / control centre

How Does the CTR Substation Automation System Work?

The CTR system is built on a client-server architecture. Substation devices collect and store data from the servers. Operator clients then connect to the servers to monitor status, alarms and trends, and issue commands.

Key working points:

  • Servers exchange and store data accurately.
  • A main server and a backup server run together. If the main server fails for any reason.Then the system automatically switches to the redundant server.
  • Any changes to the configuration are automatically transferred to all servers.So every server always runs the same setup.
  • The system monitors its own network connectivity. Also alerts operators when a link is lost.
  • Local and remote diagnostic tools help engineers find problems without visiting the site.
  • Operators can also connect through a web server.

How to Choose a Substation Automation System

Choosing an SAS should not be based only on price. It must match your substation layout, devices, and operating practice.

Important selection parameters include:

Parameter Why It Matters
Number of bays and devices Defines system size and server capacity
Communication protocols (IEC 61850 and others) Decides compatibility with existing relays and meters
Network topology Affects reliability and cabling design
Redundancy requirement Decides whether you need main and standby servers
New or retrofit project Changes the engineering and shutdown plan
Future expansion Determines how much capacity to allow
Remote access needs Defines web server and remote configuration setup
Language and site requirements Language and site requirements
