One feature directly emulates structures that use the ID, IDREF
, and attribute types from the XML document type definitions.
Therefore, based on the references for active and reactive powers Pref and Qref, the reference currents iqref and idref
in d-q domain can be calculated using (4), where Vsq is the system voltage in q-domain and the reference currents are calculated using (5).
He includes only one page about ID and IDREF
, the principal constructs in SGML for making hypertext links.
