For a secure power system operation, voltage stability is of great concern. For any system
the main reason for deterioration of the voltage profile and reduced is the reactive load.. Compensators
are used to maintain the voltage stability and reduce the voltage drop. The compensation is provided
using the switching devices such as circuit breakers or semiconductor devices. The synchronous gate
pulse generation models also help in keeping the power system well in control and synchronism.
Closed loop control is also shown for Thyristor Switched Capacitor. Stable voltage with dynamic load
changes is obtained using FACTS controllers (TSC).
