What is PD CLC/TS 50654‑1 about?
PD CLC/TS 50654‑1 is the first part of the PD CLC/TS 50654 series of documents on HVDC grid systems and connected converter stations. PD CLC/TS 50654‑1 is an international standard on HVDC grid systems and connected converter stations that aim to improve the efficiency of transmitting enormous amounts of electricity over long distances.
PD CLC/TS 50654‑1 describe specific functional requirements for HVDC Grid Systems. The terminology “HVDC Grid Systems” is used here describing HVDC systems for power transmission having more than two converter stations connected to a common DC circuit.
PD CLC/TS 50654‑1 is applicable to high voltage systems, i.e., having typically nominal DC voltages higher than 50 kV with respect to earth are considered in PD CLC/TS 50654‑1.
Note: While the physical principles of DC networks are voltage-independent, the technical options for designing equipment get much wider with lower DC voltage levels, e.g., in the case of converters or switchgear.
Who is PD CLC/TS 50654‑1 for?
PD CLC/TS 50654‑1 on HVDC grid systems and connected converter stations is useful for:
- HVDC grid systems manufacturers
- HVDC grid systems designers
- Entities involved in the installation of HVDC grid systems
- Testing laboratories/ test providers for HVDC grid systems
Why should you use PD CLC/TS 50654‑1?
HVDC Grid Systems are a new field of technology. There are very few systems with a small number of converter stations in operation, some more are in execution or in detailed planning.
PD CLC/TS 50654‑1 provides you with guidelines for functional specification of HVDC grid systems and connected converter stations.
The guidelines, characteristics, installation requirements provided by PD CLC/TS 50654‑1 helps you to improve the efficiency of HVDC power transmissions between convertor stations and to expand the energy networks.
