Consultations

The Authority has reviewed the obligations in the Code for non-faulted generating assets to remain connected during transmission faults, to supply enough reactive power to reduce voltage dip, and to provide enough short-circuit current to allow protection relays to clear faults correctly. As a result of the review's findings, the Authority proposes that fault ride through standards for all generating plant be added to the Code. Separate standards in the form of ride through envelopes are proposed for the North and South Islands.

This is a second consultation taking into account submissions received on a consultation carried out in February 2011.
