What is PD IEC/TS 63014-1 – HVDC power transmission about?
PD IEC/TS 63014-1 is an international standard that discusses using line-commutated converters for high voltage direct current (HVDC) power transmission. HVDC is more environmentally friendly than AC, providing more energy per square metre over greater distances more efficiently than AC systems, as well as lower losses and fewer space requirements.
PD IEC/TS 63014-1 is intended to provide an overall and consistent set of guidelines to facilitate the specification of equipment for the DC-side of a high-voltage direct current (HVDC) system using line-commutated converters.
For point-to-point HVDC transmission systems, PD IEC/TS 63014-1 covers all DC-side equipment located between the converter valves and the DC overhead line or cable termination, excluding the converter valves themselves.
For back-to-back HVDC systems, PD IEC/TS 63014-1 covers all DC-side equipment excluding the converter valves themselves. Throughout this publication, the terms 'direct voltage' and 'DC voltage' are used interchangeably, as are 'direct current' and 'DC'.
Although product standards exist for some DC-side equipment types, many such items of equipment have only standards written for AC applications and, in such cases, the purpose of PD IEC/TS 63014-1 is to provide guidance as to how to specify the additional requirements (particularly about testing) for such equipment to cover their use in DC conditions.
Note: PD IEC/TS 63014-1 includes requirements for DC disconnectors and certain types of specialised DC switching devices (such as the Metallic Return Transfer Switch (MRTS)), it excludes any type of DC circuit-breaker designed to interrupt fault currents.
Who is PD IEC/TS 63014-1 - HVDC power transmission for?
PD IEC/TS 63014-1 on HVDC power transmission applies to:
- Manufacturer of HVDC stations
- Electrical engineers
- Quality testing personnel
Why should you use PD IEC/TS 63014-1 - HVDC power transmission?
HVDC allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. Line-commutated converters (LCCs) are the conventional, mature and well-established technology used to convert electric power from AC to DC or vice versa.
PD IEC/TS 63014-1 provides you with the term line-commutated which helps you to indicate the conversion process relies on a stable line voltage, with clear zero-crossings of the AC system to which the converter is connected to have a flow commutation from one switching element to another. DC-side equipment is a collection of high-voltage equipment which is located on the DC side of the HVDC converter in a converter station.
PD IEC/TS 63014-1 provides you with comprehensive information useful throughout the process of line-commutated converters for high voltage direct current (HVDC) power transmission.
