Omfang

IEC 62501:2024 applies to self-commutated converter valves, for use in a three-phase bridge voltage sourced converter (VSC) for high voltage DC power transmission or as part of a back-to-back link, and to dynamic braking valves. It is restricted to electrical type and production tests. This document can be used as a guide for testing of high-voltage VSC valves used in energy storage systems (ESS). The tests specified in this document are based on air insulated valves. The test requirements and acceptance criteria can be used for guidance to specify the electrical type and production tests of other types of valves. This edition includes the following significant technical changes with respect to the previous edition:a) Conditions for use of evidence in lieu are inserted as a new Table 1;b) Test parameters for valve support DC voltage test, 7.3.2, and MVU DC voltage test, 8.4.1, updated;c) AC-DC voltage test between valve terminals, Clause 9, is restructured and alternative tests, by individual AC and DC voltage tests, added in 9.4.2;d) Partial discharge test in routine test program is removed;e) More information on valve component fault tolerance, Annex B, is added;f) Valve losses determination is added as Annex C.
