POWER FACTOR IMPROVEMENT USING STATIC VAR COMPENSATOR
Dr. Umer Tabrez Shami
Normally power systems are subjected to small disturbances resulting from minor load
changes to change in mechanical inputs to a power system. After an abnormal condition,
when a system converges to some new values it is said to be dynamically stable system.
Many techniques are utilized nowadays to rectify these contingencies. Restrictions on
the construction of new system have forced the design engineers to look for some unconventional
solutions to increase the power system stability and efficiency. Since the
construction of new power system are both expensive and time-consuming, solution to
the problem has been found in Flexible AC Transmission System (FACTS) devices.
This project describes the implementation of SVC on Single Phase to provide improved
Voltage stability, controlled power factor, and efficient Reactive Power feeding. Main
purpose of the project is to provide reactive power to the system to improve power factor
and time for which capacitor and inductor are added in the system has to be made Variable. This
has been achieved by using TRIAC and Relays. We monitor the power factor
through Microcontroller and when it is below certain limits than capacitor (inductor) is
added for lagging load (leading load) by switching the TRIAC through relay.
