IEC TR 61000-3-14-2011是一份技术报告，提供了可作为确定干扰装置与低压（LV）公共电力系统连接要求基础的原则指南。就IEC 61000本部分而言，干扰装置是指产生干扰的装置（可能是负载或发电机）:谐波和/或间谐波、电压闪烁和/或快速电压变化和/或电压不平衡。主要目标是为系统运营商或业主提供工程实践指导，这将有助于为所有连接的客户安装提供足够的服务质量。 在处理装置时，本报告不打算取代排放限值的设备标准。本报告阐述了系统吸收干扰的能力分配。它没有说明如何减轻干扰，也没有说明如何增加系统的容量。

IEC TR 61000-3-14:2011 is a Technical Report which provides guidance on principles that can be used as the basis for determining the requirements for the connection of disturbing installations to low voltage (LV) public power systems. For the purposes of this part of IEC 61000, a disturbing installation means an installation (which may be a load or a generator) that produces disturbances: harmonics and/or interharmonics, voltage flicker and/or rapid voltage changes, and/or voltage unbalance. The primary objective is to provide guidance to system operators or owners for engineering practices, which will facilitate the provision of adequate service quality for all connected customer installations. In addressing installations, this report is not intended to replace equipment standards for emission limits. This report addresses the allocation of the capacity of the system to absorb disturbances. It does not address how to mitigate disturbances, nor does it address how the capacity of the system can be increased.
