IEC/IEEE 62271-37-013:20 21适用于三相交流高压发电机断路器，以下称为发电机断路器，设计用于室内或室外安装，并在电压高于1 kV至38 kV的系统上以50 Hz和60 Hz的频率运行。 本文档作为IEC/IEEE双标识标准发布。 IEEE标准C37.013？-1997（R2008）修订并转换为2015年发布的IEC/IEEE双标识国际标准IEC/IEEE 62271-37-013的第一版。 这第二版取消并取代了2015年出版的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: 增加了满足发电机断路器系统其他部件要求的内容；增加了发电机断路器在多台发电机连接一台升压变压器的发电厂中的应用要求； 增加了开式发电机断路器试验和应用的要求； 增加了发电机断路器在具有双馈感应电机的发电厂、抽水蓄能发电厂、风电场的应用要求； 条款编号已与IEC 62271-1:20 17中的编号一致； 对参考机械特性的主题进行了修订，以提高清晰度； 附录M和附录N中使用名为“GenCB TRV计算器”的工具讨论了电容器对异相和负载电流开关的预期TRV的修改作用。该工具提供KE2、RRRV0、KRRRV-的值U、KRRRV-I、td0、Ktd-U、Ktd-I，以及由发电机断路器的电容器修改的预期TRV的参数值。 本文件包含Excel电子表格形式的附件（“GenCB TRV计算器”）。这些文件旨在作为补充，并不构成文档的组成部分。

IEC/IEEE 62271-37-013:2021 is applicable to three-phase AC high-voltage generator circuit-breakers, hereafter called generator circuit-breakers, designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 kV and up to 38 kV.
This document is published as an IEC/IEEE Dual Logo standard.
The IEEE Std C37.013？-1997 (R2008) was revised and converted into the first edition of the IEC/IEEE Dual Logo International Standard IEC/IEEE 62271-37-013 published in 2015.
This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

1. content has been added to address the requirements of the other components of the generator circuit breaker system;
2. requirements for the application of generator circuit-breakers in power plants with multiple generators connected to one step-up transformer have been added;
3. requirements for testing and application of Tee-OFF generator circuit-breakers have been added;
4. requirements for application of generator circuit-breakers in power plants with doubly-fed induction machines, pumped-storage power plants, and wind farms have been added;
5. the clause numbering has been aligned with the numbering in IEC 62271-1:2017;
6. the topic of reference mechanical characteristics has been revised to improve clarity;
7. the modifying effects of capacitors on the prospective TRVs for out-of-phase and load current switching has been addressed in Annex M and in Annex N with use of the tool named "GenCB TRV calculator". This tool provides the values of KE2, RRRV0, KRRRV-U, KRRRV-I, td0, Ktd-U, Ktd-I, as well as the values of the parameters of the prospective TRV modified by the capacitors of the generator circuit-breaker.
