并联连接的有源矫正设备（ACD

[中文适用范围]： IEC 63497:2026（产品标准）旨在规定额定系统电压不超过1000V交流电或1500V直流电的并联型有源校正装置（ACD）的电磁兼容（EMC）、性能及安全要求。此类装置可为软线连接或永久固定安装，且可为移动式、固定式或永久安装设备。ACD包含静态无功发生器（SVG）和有源谐波滤波器（AHF）。并联型ACD的主要功能包括以下一项或多项：—有源谐波滤波；—无功功率补偿；—不平衡负载补偿。本文件未涵盖的并联型ACD附加功能可能包括：—闪变补偿；—间谐波滤波。对于将无源滤波器与ACD集成的混合型设备，本文件仅适用于其中的有源部分。本文件不适用于：—其他设备（如变频器、不间断电源、动态电压恢复器等）中的有源抑制功能部分；—切换式电力电容器；—切换式电抗器；—无源谐波滤波器；—能量存储变换器；—串联型有源校正装置。 [外文原描述]： IEC 63497:2026, which is a product standard, is intended to specify the EMC, performance and safety requirements of shunt-connected active correction devices (ACD) with rated system voltages not exceeding 1 000 V AC or 1 500 V DC. These devices can be either cord or permanently connected. They can be movable, stationary, or fixed devices. An ACD includes both a static VAR generator (SVG) and an active harmonic filter (AHF). The primary function of a shunt connected ACD is to do one or more of the following: - active harmonic filtering; - reactive power compensation; - unbalanced load compensation. Additional functions of a shunt-connected ACD, not addressed by this document, can be the following: - flicker compensation; - interharmonic component filtering. In case of hybrid devices, combining a passive harmonic filter and an ACD, this document covers only the active part. This document does not cover - active mitigation functions part of another device (variable speed drive, uninterruptible power supply, dynamic voltage restorer, etc.), - switched power capacitors, - switched inductors, - passive harmonic filters, - energy storage converters, and - series-connected active correction devices.
