HVDC Converters are an assembly of valves which have the propertyof conducting in the forward direction and blocking in the reverse directions. The term 'valve'carried over from the mercury are valve days, is applied even now for thyristor valves which are made up of series and parallel connection of many thyristor cells or devices.

Triggering and monitoring system for thyristor valves for HVDC applications Abstract: Thyristor valves for HVDC applications comprise of a number of thyristors in series.
Each thyristor has a local electronics unit, which is optically interfaced with the Cited by: 5. Abstract: The worldwide trend in the evolution of high voltage thyristor valves is reviewed, using HVDC applications as an example. The key technologies involved are identified.
It is shown that the move towards direct light triggered thyristors (LTT) is but the most recent step in a continuous effort to simplify high voltage thyristor valve technology and make it inherently more reliable.
The ac/dc substation control equipment, pole control equipment, protection equipment, and auxiliary secondary equipment of high-voltage direct-current (HVDC) transmission systems are the focus of this guide. Based on analyzing the existing HVDC transmission projects, specifications for structure, configuration, performance and test of HVDC control and protection equipment, which could be.

These tests cover only the principal tests on the valves and do not include tests of auxiliary equipment associated with the values. cordance with IEC Standard Publication and IEEE Std. A test valve with LTT was installed by ASEA in the Konti-Skan link in as a replacement for a mercury arc valve .
If triggering of the thyristors is the only desired feature it is possible to eliminate all electronics at the thyristor. a commercial HVDC plant, besides the extensive test programme at the manufacturing plant. The approach of field testing is in line with ABB's philosophy, following test valves at Sylmar (USA), Vester Hassing (Denmark) and Stenkullen (Sweden) converter stations.
