Contents of this chapter
This chapter describes the operation principle and the construction of the wind turbine
converter.
Operation principle
The ACS880-87LC is a four-quadrant, cabinet-mounted liquid-cooled converter intended
for full power conversion turbines with an induction generator or a permanent magnet
generator. The converter is connected between the generator stator and the grid. The
converter can be installed up in the nacelle or down on the ground level.
The converter consists of back-to-back connected cubicles that contain the grid-side converter
modules, generator-side converter modules, LCL filter, terminals or grid busbars for grid
cables and terminals for generator cables, internal control circuits, external control cable
terminals, auxiliary circuits and external auxiliary power supply terminals.
