This document applies to all line-commutated high-voltage direct current (HVDC) converter stations used for power exchange (power transmission or back-to-back installation) in utility systems. This document presumes the use of 12-pulse thyristor converters but can, with due care, also be used for 6-pulse thyristor converters.

Aug 31, 2020Losses of a converter station can be easily estimated from calculation of two main equipments, valve and transformer, because proportion of two equipments accounts for more than 80% of the total values in the HVDC converter station.

Turnkey rail frequency converter station located at the Datteln railway hub and capable of supply-ing upto 412 MW to the German railways. • World’s most powerful rail converter station with four identical converter blocks with a rated power of 103 MW • Design, engineering, installation and commis -

The vibration on-line monitoring system of power transformer is an important part of power equipment on-line monitoring technology whose model should meet the requirements of IEC 61850.Based on an

The total losses of the HVDC converter station should be arrived at as the sum of the losses of each piece of equipment. It is important to note that the actual losses in each piece of equipment will depend on the ambient conditions under which it operates, as well as on the operating conditions or duty cycles to which it is applied.

The harmonic-current problems addresses the international community in the IEC 1000-3-2 document (the successor of the IEC 555-2), which establishes requirements that limit harmonic-current injection into the public supply system. The IEC 1000-3-2 addresses equipment with nominal line-to-neutral voltages of 220 V and higher.

This Technical Brochure examines the full extent of possible technical concerns in the area of harmonics and filtering of the installation of HVDC converter stations in close proximity. It provides guidance on the pre-specification studies to screen the possibility of harmonic interactions and to determine specific system data and technical requirements, such as network harmonic impedance

The short circuit impedance of converter transformer is taken as 24% for both ends of transmission line;the rated capacity of converter transformer at rectifier station is 542.11 MVA and that at

IEC 60270 and IEEE C57.113 IEC 60270 and IEEE C57.113 include more details compared with other standards concerning PD tests, and both give overall specifications on PD measurement circuits and PD test methods. However, it is the detailed specifications on methods of interference suppression and PD pattern recognition that they lack.

The IEC 60870-5 standards address the basic goals of telecontrol systems and their particular environmental conditions. IEC 60870-5 does not define one particular protocol profile; but rather like EPRI/UCA, it specifies a number of frame formats and services that may be provided at different layers.
