HIGH VOLTAGE SERIES REACTORS FOR LOAD FLOW CONTROL

HIGH VOLTAGE SERIES REACTORS FOR LOAD FLOW CONTROL

The installation of a series reactor in line 1 increases X1. Using the condition for the line phasors j X1 I1 = j X2 I2, it is obvious that the current I1 is also decreased by the ratio of the reactances – the "load flow control" shifts more power to the (e.g. stronger) line 2. 3 CHARACTERISTICS OF HIGH VOLTAGE SERIES REACTORS
