标准摘要
[中文适用范围]: 本技术规范IEC TS 62578描述了所有技术类型和拓扑结构的有源馈电转换器(AIC)的运行条件和典型特性,这些转换器可连接在交流侧的电气电源网络(线路)和恒定电流或电压类型的直流侧之间,并能在两个方向(发电或再生)转换有功和无功功率。 有源馈电转换器的应用通常与可变速度电力驱动系统(PDS)的直流侧、不间断电源系统(UPS)、有源滤波器、光伏系统、风力涡轮机系统、电池供电的电源管理系统等的直流侧一起使用,涵盖所有电压和功率等级。 有源馈电转换器通常连接在交流侧的电气电源网络和电流或电压直流侧之间,目的是通过合成正弦交流电流来避免发射低频谐波(例如低于1 kHz)。其中一些还可以补偿给定供电侧电压的现有谐波畸变。它们还能够通过双向(发电或再生)移动有功和无功功率来控制电源网络部分的功率因数,这可以节约系统能源、稳定供电电压或实现可再生能源或电能存储设备与电网的耦合。 本规范提供基于2 kHz至9 kHz线路阻抗最新结果和直接连接到电源的电容器的耐受能力得出的AIC在电源网络中发射值的实用和解析方法。由此得出低于150 kHz的发射值设计建议。 以下范围不包括:AIC应用的设计、开发或进一步功能要求;由于安装中的寄生元件或糟糕的电子产品设计导致的AIC与其他设备相互作用的概率或影响及其缓解措施;由于缺乏其三相阻抗测量信息而排除的“架空线”电源网络。 [外文原描述]: IEC TS 62578:2015 describes the operation conditions and typical characteristics of active infeed converters (AIC) of all technologies and topologies which can be connected between the electrical power supply network (lines) a.c. side and a constant current or voltage type d.c. side and which can convert electrical power (active and reactive) in both directions (generative or regenerative). The following is excluded from the scope: - Requirements for the design, development or further functionality of active infeed applications. - Probability of interactions or influences of the AIC with other equipment caused by parasitic elements in an installation or caused by poor electronic design as well as their mitigations. - "Overhead line" power supply networks because of lack of information (measurements) of their three phase impedances. This edition includes the following significant technical changes with respect to the previous edition: a) IEC TS 62578, in its revised version includes observed values out of practical applications for emission values below 150 kHz. b) Therefore the document has been extended compared to the first edition, several detailed analysis results are given in the extended Annexes. c) Design recommendations have been derived from the international working group by an assessment of the power supply impedances between 2 kHz and 9 kHz, a comprehensive analysis of the withstand capability of power capacitors against harmonic currents injected by AIC, immunity tests of equipment and considerations about shifted resonances in the power supply network with increased population of undamped filter capacitors.
