The stability of a system, when subjected to a disturbance, is assessable by which of the following methods? 1. Swing curve 2. Equal-area criterion 3. Power-angle diagram 4. Power-circle diagram

The stability of a system, when subjected to a disturbance, is assessable by which of the following methods? 1. Swing curve 2. Equal-area criterion 3. Power-angle diagram 4. Power-circle diagram Correct Answer 1, 2 and 3 only

The stability of a system when subjected to a disturbance can be estimated by using the solution of

  1. Swing curve
  2. Equal area criterion
  3. Power angle diagram


On the other hand, a power circle diagram is used to find the rating of compensator but it won’t assess the stability of the system.

Hence statements 1, 2, 3 are correct and statements-4 is false
