規格概要
IEC TR 63282:2024, which is a technical report, collects information and report experience for the standardization of voltage levels and related aspects (power quality, EMC, measurement, etc.) for LVDC systems (systems with nominal voltage up to and including 1 500 V DC).
Rationale for the proposed voltage values is given. Variation of parameters for the voltage (power quality) for their boundaries are defined. Nevertheless, some of the technical items are not exhaustively explained in this document and some gaps are identified for future work.
Attention is paid to the definition of DC voltage.
Systems in which a unipolar voltage is interrupted periodically for certain purposes, e.g. pulse voltage, are not considered.
Traction systems are excluded from this document.
This document gives technical inputs to TCs in charge of the standardization of different issues and coordinated by SyC LVDC.
This second edition cancels and replaces the first edition published in 2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Optimized terms and definitions in Clause 3: DC system nominal voltage is modified. Oscillation is added. Active distribution system, passive distribution system are deleted.
b) Modified the definition of voltage bands: In Clause 5, the definition of voltage limits in voltage bands is added, from U1 to U6. The definition of voltage bands, from B4 to B7, is modified.
c) Distinguished the difference between oscillation and power quality phenomenon: In Clause 3, the definition of oscillation is added based on IEV 103-05-04. In 6.3, relationship between oscillation and power quality is clarified. Annex B gives a LDC oscillation typical example which has really happened in a MV&LVDC system in China.
d) Modified the recommended voltage for distribution DC network: The factors considered in voltage values
