Fig. 8.37 Waveforms in the TCSC operating with closed-loop control. Disturbance occurs at t 1:8 s: (a)
voltage V S ofthe source; (b) voltage V L at the TCSC inductor; (c) current I L through the TCSC inductor; (d)
voltage V C at the TCSC capacitor; and (e) current I C through the TCSC capacitor.
response are the initial operating point for the firing angle a, the amount of change
required, and the amount of net series compensation involved between operating points.
8.6 Static Compensator (STATCOM)
The STATCOM belongs to a family of power electronics controllers that base their
operation on the VSC principle. These converter topologies have been presented in
