[0039] Example 1:
[0040] Figure 2 shows a three-phase system composed of three single-phase reactors. The grid-side windings in each phase are two sets of coils H 12 , H 13 The group is a parallel structure, each phase of the control winding has K 14 , K15 Two coils, a group of coils with the same name between the phases are connected end to end to form a series branch. The two branches are connected in parallel, and the two parallel terminals a and b are respectively connected to the output terminals of the rectifier and filter device. Grid side winding H after three-phase Y connection 12 , H 13 One end is respectively connected to a three-phase transmission line, the other end is connected to a small reactor, and the other end of the small reactor is grounded. The rectifier and filter device 2 is externally connected to an AC power source, the output ends of the rectifier and filter device are connected to ends a and b of the control winding, and the thyristor group in the rec...
