Smart Grid Emergency - Load Restoration

The Load Restoration application minimizes the duration of an outage following a disturbance by automatically restoring power to the available portions of the system while maintaining fault isolation without exceeding the capacities of alternate power sources and routes.

Restoration qualification feature evaluates the ability to restore loads by monitoring and comparing the following parameters:

• System frequency
• Available spinning reserve
• Starting voltages
• Operating voltages
• User-defined logic
• Alternate source detection
• System configuration status
• Interlock & switching sequence logics

Operator notification and acknowledgement provides the means that allow the dispatcher to restart the loads. Armed with Switching Management, loads can be restarted step-by-step or in one action. Where the restarting is determined to be invalid or unsafe, ETAP automatically inhibits the restart and provides the system operator with an indication that the load cannot be started.
