What is PD CLC/TS 50654‑2 about?
PD CLC/TS 50654‑2 is the second part of the PD CLC/TS 50654 series of documents on HVDC grid systems and connected converter stations. PD CLC/TS 50654‑2 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 50654‑2 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 50654‑2 focuses on requirements, that are specific for HVDC Grid Systems, some requirements are considered applicable to all HVDC systems in general, i.e., including point-to-point HVDC systems
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 50654‑2 for?
PD CLC/TS 50654‑2 on HVDC grid systems and connected converter stations is useful for:
- HVDC Grid Systems installers
- HVDC Grid Systems designers
- Testing laboratories/ test providers for HVDC Grid Systems
Why should you use PD CLC/TS 50654‑2?
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 50654‑2 provides you with parameter lists for functional specification of HVDC grid systems and connected converter stations.
The guidelines, characteristics, installation requirements provided by PD CLC/TS 50654‑2 helps you to improve the efficiency of HVDC power transmissions between convertor stations and enables you to expand the energy networks.
