Grid support
In the grid support function, the grid is supported by feeding reactive current to it. The
reactive current reference is defined as a function of the grid voltage. Six different voltage
levels can be defined. Examples of setting the grid support parameters are shown in the
diagrams below. For further information, see
ACS800-67(LC) doubly-fed induction
generator control program firmware manual [3AUA0000071689 (English)].
