Design of active series compensator for real power flow rerouting in transmission system

摘要

In this paper, the real power flow control in a transmission line is done by using active series compensation technique. The active compensator varies the power angle in the line using a power electronic device. The power angle is varied by injecting voltage to the line that is in phase shift with line voltage. This varies the real power flow in transmission line. Using this technique, the rerouting of power flow can be achieved to satisfy the inequality constraints. By controlling the injected voltage magnitude and the phase angle, accurate power flow control can be achieved. In this paper, an embedded system based active series compensator is developed and the power flow control in a two bus system is achieved effectively.
