Application examples

Features and Benefits

IT based solution for protection and control offer cost effective measures to counteract large area system disturbances.

Effective fault location is mandatory for faster finding and fixing of problems.

Integrated numerical protection & control allows automated power restoration and load shedding.

On-line condition monitoring reduces maintenance costs and enables.

Substation Automation offers a cost effective infrastructure for implementing on-line condition monitoring of assets.

Voltage instability prediction is a new approach for early indication voltage collapses and enables to work plants and systems harder.

Integrated asset management improves overall utility performance and productivity.

General Principles of Substation Automation

The general principles of the substation operation have not changed, since their developing days. Therefore the control and protection tasks remain the same.

The objective of modern substation automation (SA) is to solve these tasks in a more efficient and economical way by using state of the art information technologies (IT) and to provide more functionality to work plant and systems harder.
