旋转电机第3部分:汽轮机或燃气轮机驱动的同步发电机和同步补偿器的特殊要求

[中文适用范围]： 本部分IEC 60034适用于额定输出为10 MVA及以上的由蒸汽轮机或燃烧燃气轮机驱动的大型三相同步发电机。还包括连接至电网用于交换无功功率的同容量范围的同步无功补偿器。本文件补充了IEC 60034-1中给出的旋转电机的基本要求。空气、氢气或液体冷却的同步发电机或补偿器的通用要求与具体要求一起规定。本文件还给出了使用氢气冷却发电机时应采取的预防措施，包括：由同步发电机驱动的旋转励磁机；运行发电机所需的辅助设备；氢气可能积聚的建筑物部分。这些要求也适用于由蒸汽轮机和燃烧燃气轮机共同驱动作为单轴联合循环机组一部分的同步发电机。这些要求不适用于由水轮机或风力涡轮机驱动的同步发电机。注：使用氢气时采取的预防措施适用于所有使用氢气作为冷却剂的情况。 [外文原描述]： IEC 60034-3:2020 applies to large three-phase synchronous generators, having rated outputs of 10 MVA and above driven by steam turbines or combustion gas turbines. Also included are synchronous Mvar compensators of the same output range connected to a grid for the purpose of exchanging reactive power. This document supplements basic requirements for rotating machines given in IEC 60034-1. This seventh edition cancels and replaces the sixth edition published in 2007. This edition includes the following significant technical changes with respect to the previous edition: - title modified; - scope extended to synchronous compensators; - rotor overcurrent requirements added; - impact of stator harmonics on rotor unbalanced load capability introduced; - synchronisation requirements added; - adjustments of temperatures or temperature rise revised for gas turbine applications; - requirements for auxiliaries updated.
