5.3: Feedback Compensation
Similarly, problems associated with nonlinearities and noise are often accentuated by series compensation, yet may actually be reduced by feedback compensation. The approach to finding the type of feedback compensation that should be used in a given application is to consider the negative of the loop trans mission for the system of Figure 5.20.
Series compensation goes the distance
In places like South America series compensation is proving a very cost-effective way of increasing capacity and maintaining stability in long distance transmission corridors - avoiding the expense of new lines.
