CONTENTS
5.9 Series filter losse
Replace the entry as follows (to correct the misprint):
5.9 Series filter losses
3.1.1
auxiliary losses
Replace the existing definition by the following new definition and new note:
electric power required to feed the converter station auxiliary loads
NOTE 1 to entry: The auxiliary losses depend on the number of converter units used and whether the station is in
no-load operation or carrying load, in which case the auxiliary losses depend on the load level.

3.1.2
no-load operation losses
Replace the term and its definition as follows:

IEC 61803:1999/AMD2:2016 – 3 –
© IEC 2016
3.1.2
equipment no-load operation losses
losses produced in an item of equipment with the converter station energised but with the
converters blocked and all station service loads and auxiliary equipment connected as
required for immediate pick-up of load to specified minimum power

3.1.4
operating losses
Replace the existing term by the following new term:
3.1.4
equipment operating losses
3.1.5
rated load
Replace the existing definition by the following new definition and note:
load related to operation at nominal values of d.c. current, d.c. voltage, a.c. voltage and
converter firing angle
Note 1 to entry: The a.c. system shall be assumed to be at nominal frequency and its 3-phase voltages are
nominal and balanced. The position of the tap-changer of the converter transformer and the number of a.c. filters
and shunt reactive elements connected shall be consistent with operation at rated load, coincident with nominal
conditions.
3.1.6
total station losses
Replace the existing term and its definition by the following new term, definition and notes:
3.1.6
total station operating losses
sum of all equipment operating losses (3.1.4) and corresponding auxiliary losses (3.1.1) at a
particular load level
Note 1 to entry: It is recognised that some purchasers evaluate “total station no-load operation losses” (definition
3.1.8) and total station load losses individually instead of the evaluating “total station operating losses” (definition
3.1.6).
Note 2 to entry: "Operating losses” minus “no-load operation losses” may be considered as being quantitatively
equivalent to “load losses” as in conventional a.c. substation practice.
Note 3 to entry: An illustrative example to derive “load losses”, “equivalent load losses” and corresponding “loss
evaluation” is given in Annex D.

3.1.7
station essential auxiliary load
Delete, in the definition added by Amendment 1, the Note.
