Module 2 : Equipment and Stability Constraints in System Operation
Lecture 6 : Transmission Line constraints
 
   Recap
   In this lecture you have learnt the following
Power transfer capability of a ac line is restricted by thermal and voltage constraints
   
Short lines are limited by thermal constraints
   

Long lines are limited by voltage constraints. Stability constraints are also important for long ac lines and are studied in the next lecture

   
  Congratulations, you have finished Lecture 6. To view the next lecture select it from the left hand side menu of the page.
