Assessment of oscillation<br />
• Scan all transmitt<strong>in</strong>g power<br />
under normal state.<br />
• If oscillation power > 10MW<br />
and duration > 5 oscillat<strong>in</strong>g<br />
cycles, the event is registered.<br />
• Statistics shows: oscillation<br />
with poor damp<strong>in</strong>g will have<br />
more events.<br />
• The assessment successfully<br />
predicts dangerous oscillation<br />
event before its real<br />
occurrence.<br />
