本指南涵盖了具有圆柱形转子的涡轮驱动同步发电机（称为涡轮发电机）的操作、加载和维护的一般建议。它不适用于带有凸极转子的发电机。 本指南涵盖的发电机应具有10 MVA及以上的额定输出。NEMA MG 1.1通常涵盖了低于该额定值的圆柱转子、两极和四极发电机。本指南不打算取代制造商说明书或制造商与给定机器买方之间的任何合同协议中包含的具体或一般说明。 由于发电机设计的快速发展，以及各个发电机设计师的独创性，现有机器中加入了许多变化。因此，在本指南中不可能指定特定值或固定方法。本指南所能完成的最大任务就是提供被接受的 尝试价值观和方法，并在可能遇到危险的地方发出警告。用户应记住，本指南旨在涵盖汽轮发电机。本指南无意以任何方式适用于原动机。

This guide covers general recommendations for the operation, loading, and maintenance of turbine-driven synchronous generators, termed turbine generators, having cylindrical rotors. It does not apply to generators having salient pole rotors. The generators covered by this guide are to have rated outputs of 10 MVA and above. Cylindrical-rotor, two-pole and four-pole generators below this rating are generally covered by NEMA MG 1.1 This guide is not intended to supplant specific or general instructions contained in the manufacturer's instruction book or in any contractual agreement between a manufacturer and a purchaser of a given machine. Because of the rapid development in generator design and because of the ingenuity of individual generator designers, many variations are incorporated in existing machines. Therefore, it is not possible in this guide to assign specific values or fixed methods. The most that this guide can accomplish is to offer accepted and tried values and methods and give warning where hazards might be encountered. The user should keep in mind that this guide is written to cover the turbine generator. This guide is not intended to apply in any manner to the prime mover.
