IEC TR 62544:2011 pdfダウンロード High-voltage direct current (HVDC) systems – Application of active filters
1 Scope
This technical report gives general guidance on the subject of active filters for use in highvoltage direct current (HVDC) power transmission. It describes systems where active devices are used primarily to achieve a reduction in harmonics in the d.c. or a.c. systems. This excludes the use of automatically retuned components.
The various types of circuit that can be used for active filters are described in the report, along with their principal operational characteristics and typical applications. The overall aim is to provide guidance for purchasers to assist with the task of specifying active filters as part of HVDC converters.
Passive filters are specifically excluded from this report.

3 Terms and definitions
For the purposes of this technical report, the terms and definitions given in IEC 60633 and IEC 62001 :2009 for passive a.c. filters, as well as the following apply.
NOTE Only terms which are specific to active filters for HVDC are defined in this clause. Those terms that are either identical to or obvious extensions of IEC 60633 or IEC 62001 :2009 terminology have not been defined.
3.1 Active and passive filters
3.1 .1
active filter
a filter whose response to harmonics is either wholly or partially governed by a controlled onverter
3.1 .2
passive filter
a filter whose response to harmonics is governed by the impedance of its components 3.2 Active filter topologies
3.2.1
shunt active filter
an active filter connected high-voltage (HV) to low-voltage (LV) or HV to ground such that it experiences the full a.c. or d.c. voltage of the HVDC system or its a.c. connection (see Figure 1 )
3.2.2
series active filter
an active filter connected between the HVDC converter and the a.c. or d.c. supplies such that it must withstand the full HVDC system current, either a.c. or d.c. (see Figure 2)
3.2.3
shunt and series active filter
an active filter containing both series and shunt elements as defined above
