This guide contains instructions for modeling synchronous machines in direct- and quadrature-axis equivalent circuits, along with the basic transient and subtransient reactance/time-const
Foreword This guide is the introduction to the IEEE C62.92 series of five guides on neutral grounding in electrical utility systems. In this series of guides, individual considerations and practices are given to the grounding of synchronous generator systems,...
The requirements in this standard apply to all types of 60-hertz salient-pole synchronous generators and generator motors rated 5000 kVA (kilovolt amperes) and above to be used for hydraulic turbine or hydraulic pump turbine applications. Definitions, characteristics, and test...
This guide contains instructions for conducting generally applicable and accepted tests to determine the performance characteristics of synchronous machines. Although the tests described are applicable in general to synchronous generators, synchronous motors (larger than...
This standard contains general requirements and definitions applicable to all types of 60-Hz synchronous machines, except fractional horsepower motors. Specific requirements for salient-pole synchronous generators will be found in ANSI C50.12, cylindrical-rotor...
The requirements in this standard apply to all types of 50 Hz and 60 Hz salient-pole synchronous generators and generator/motors rated 5 MVA and above to be used for hydraulic turbine or hydraulic pump/turbine applications. Salient-pole generators and...
The requirements in this standard apply to 60 Hz open-ventilated air-cooled cylindrical rotor synchronous generators rated 10,000 kVA and above. All requirements and deÞnitions, except as speciÞcally covered in this standard, shall be in accordance with ANSI C50.10-1977 and C50...
This guide has been prepared to aid in the application of relays and relaying schemes for protection against stator ground faults on high-impedance grounded generators. The guide is not intended for the selection of generator or ground connection schemes. Differential relaying will...
The requirements in this standard apply to all 50 Hz and 60 Hz, two-pole and four-pole, cylindrical-rotor synchronous generators driven by steam turbines and/or by combustion gas turbines. The drive may be direct or through a gearbox or other device that permits different speeds for...
This document describes guidelines for online monitoring of large synchronous generators with ratings of 10 MVA and above. The scope includes generators with salient-pole rotors as well as generators with cylindrical rotors. This standard also provides basic information...
The procedures for installation described in this guide apply to all types of synchronous generators and generator/motors rated 5 MVA and above to be coupled to hydraulic turbines or hydraulic pump/turbines having vertical shafts. Purpose Large hydraulic turbine-driven...
This Standard specifies the terms and definitions related to the use of synchronous belt and synchronous pulley for mechanical power transmission and where positive indexing or synchronization is required. NOTE The International Standard corresponding to this Standard and the symbol...
The general parameters for this guide apply to 50 Hz or 60 Hz synchronous generators driven by reciprocating engines, steam turbines, combustion turbines, and hydro turbines. The guide generally applies to the stator and rotor of generators with rated outputs of 1 MVA and above...
This signal generator generates a highly stable, continuous wave (CW), and modulated signal. The unit generates amplitude modulation (AM), frequency modulation (FM), phase modulation (ØM), and pulse modulation (PM) signals with internal or external signals for modulation on demand as...
Application This guide covers general recommendations for the operation, loading, and maintenance of synchronous hydro-generators and generator/motors. It does not apply to synchronous machines having cylindrical rotors. In this guide, the term hydro-generator is...
This standard defines elements and commonly used components in excitation control systems and contains definitions for excitation systems as applied to synchronous machines. These definitions should be useful in the following areas: - Writing excitation systems specifications - Evaluating...
This document specifies the terms and definitions related to the use of synchronous belt drives for mechanical power transmission and where positive indexing or synchronization is required.
