Compensation Techniques

The compensation techniques are the methods that are employed in the electrical control systems to enhance the performance of the system. The performance are generally affected by the factors like lag in the compensating devices, slow response of the system of the components like sensors used in the control system. The basic compensation technique involves lag compensation, lead compensation or the combination of the both.

Critical Clearing Angle example
Pe=0.8 p.u. q = 0.074 p.u. connected to infinite bus of 1.0 p.u.
A Three phase fault on any of the transmission feeder lines;
Determine the critical clearing angle.
What is the critical clearing angle - The critical clearing angle is the angle through which a generator
rotor must be displaced from its equilibrium position following a disturbance (such as a fault) to just
maintain stability in a power system. In other words, it is the maximum angle by which the rotor of a
synchronous machine can be swung following a disturbance and still allow the system to reach a
