What is PD IEC/TR 62001-2 – High-voltage direct current systems about?
PD IEC/TR 62001-2 is an international standard and a part of the PD IEC/TR 62001 series that discusses the performance for guidance to the specification and design evaluation of AC filters for High-voltage direct current (HVDC) systems. HVDC allows power transmission between AC transmission systems that are not synchronized.
PD IEC/TR 62001-2 provides guidance on the performance aspects and verification of performance of harmonic filters. PD IEC/TR 62001-2 covers AC side filtering for the frequency range of interest in terms of harmonic distortion and audible frequency disturbances. It excludes filters designed to be effective in the PLC and radio interference spectra. PD IEC/TR 62001-2 concerns the "conventional" AC filter technology and line-commutated high voltage direct current (HVDC) converters.
Who is PD IEC/TR 62001-2 – High-voltage direct current systems for?
PD IEC/TR 62001-2 on high-voltage direct current systems applies to:
- Manufacturer of transmission systems
- Electrical engineer
Why should you use PD IEC/TR 62001-2 – High-voltage direct current systems?
The performance part deals with current based interference criteria, design issues and special applications, field measurements and verification. PD IEC/TR 62001-2 provides you with the harmonic performance test that covers as many configurations as practically possible such as:
- The whole operating range of the converters including the overload range and operation at reduced HVDC voltage
- Various loadings of the AC system which should also result in various short circuit levels and AC system impedances
- Operation with normal AC filtering, with reduced filtering, and with the whole range of filters (or combinations of different filter banks) which might be connected at a given power level, and
- All DC side configurations (as a DC side resonance can affect AC side distortion).
As a user of PD IEC/TR 62001-2, you can ensure the performance of High-voltage direct current systems.
What’s changed since the last update?
PD IEC/TR 62001-2:2016 supersedes PD IEC/TR 62001:2009 which will be withdrawn on publication of all parts of this series. It includes:
- Expanded and supplemented Clause 19, and Annex B and new Clause 3 on current-based interference criteria
- New annexes on induced noise calculation with Dubanton equations
- Addition of a TIF requirement in a technical specification
- Specification of IT limits dependent on network impedance and the impact of AC network harmonic impedance; and
- Specification of the voltage level on the filter design necessary to fulfil an IT criterion.
