| Recap |
| In
this lecture you have learnt the following |

|
AC systems face an inherent angular stability problem: Synchronous machines lose synchronism with each other when subjected to large disturbances |
| |
|
 |
System operators avoid the angular stability problem by operating the system conservatively |
| |
|

|
Operating conservatively implies that power flow in long ac transmission is severely curtailed due to angular stability constraints. HVDC transmission is an option for transmitting bulk power over large distances |
