CSA序言这是CAN/CSA-C61000-3-13《电磁兼容性（EMC）-第3-13部分:限值-不平衡装置与中压、高压和超高压电力系统连接的发射限值评估》的第一版，这是对标题相同的IEC（国际电工委员会）技术报告61000-3-13（第一版，2008-02）的采用，未经修改。1范围IEC 61000的这一部分提供了原则指南，可作为确定不平衡装置（i。 e、 中压、高压和超高压公共电力系统的三相装置（低压装置在其他IEC文件中有介绍）。在本报告中，不平衡装置指在系统上产生电压不平衡的三相装置（可能是负载或发电机）。由于单相装置的连接由系统运营商或业主控制，因此未具体说明单相装置的连接。然而，在考虑单个管道的连接时，可对一般原则进行调整- 安装阶段。主要目标是为系统运营商或业主提供工程实践方面的指导，这将有助于为所有相关客户提供足够的服务质量。在解决安装问题时，本文件无意取代排放限值的设备标准。该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。由于本报告中概述的指南必然基于某些简化假设，因此无法保证该方法始终为所有不平衡负载情况提供最佳解决方案。 当全部或部分应用给定的评估程序时，就工程而言，建议的方法应具有灵活性和判断力。系统操作员或所有者负责规定可能导致系统不平衡的装置连接要求。干扰安装应理解为客户的完整安装（即包括平衡和不平衡部件）。

CSA PrefaceThis is the first edition of CAN/CSA-C61000-3-13, Electromagnetic compatibility (EMC) - Part 3-13: Limits - Assessment of emission limits for the connection of unbalanced installations to MV, HV and EHV power systems, which is an adoption without modification of the identically titled IEC (International Electrotechnical Commission) Technical Report 61000-3-13 (first edition, 2008-02).1 ScopeThis part of IEC 61000 provides guidance on principles which can be used as the basis for determining the requirements for the connection of unbalanced installations (i.e. three-phase installations causing voltage unbalance) to MV, HV and EHV public power systems (LV installations are covered in other IEC documents). For the purposes of this report, an unbalanced installation means a three-phase installation (which may be a load or a generator) that produces voltage unbalance on the system. The connection of single-phase installations is not specifically addressed, as the connection of such installations is under the control of the system operator or owner. The general principles however may be adapted when considering the connection of single-phase installations. The primary objective is to provide guidance to system operators or owners on engineering practices, which will facilitate the provision of adequate service quality for all connected customers. In addressing installations, this document is not intended to replace equipment standards for emission limits.The 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.Since the guidelines outlined in this report are necessarily based on certain simplifying assumptions, there is no guarantee that this approach will always provide the optimum solution for all unbalanced load situations. The recommended approach should be used with flexibility and judgment as far as engineering is concerned, when applying the given assessment procedures in full or in part.The system operator or owner is responsible for specifying requirements for the connection of installations which may cause unbalance on the system. The disturbing installation is to be understood as the complete customer's installation (i.e. including balanced and unbalanced parts).
