IEEE C50.13-1977 pdf free.American National Standard Requirements for Cylindrical-RotoSynchronous Generators.
The requirements in this standard apply to 60 hertz cylindrical-rotor synchronous generators, except those covered inC50.14-1977.
All requirements and definitions, except as specifically covered in this standard, shall be in accordance with AmericanNational Standard C50.10-77.
A cylindrical-rotor synchronous generator is classified by one of the stator and one of the rotor types.
The usual service conditions upon which the requirements for cylindrical-rotor synchronous generators are based aregiven in ANSI C50.10-1977.In addition to these usual service conditions, the following requirements shall be met.
Generators shall operate successfully at rated kilovolt-amperes (kVA), frequency, and power factor at any voltage notmore than five percent above or below rated voltage, but not necessarily in accordance with the standards ofperformance established for operation at rated voltage.
Capabilities at hydrogen pressures other than rated pressure shall be available from the manufacturer.The capabilitiesat hydrogen pressures other than rated shall be determined such that the hottest spot temperature of the winding whichis limiting at the specified capability shall be essentially the same as that at rating.The output rating shall be expressed in kilovolt-amperes available at the terminals at a specified speed, frequency.voltage, and power factor.
The output rating of hydrogen-cooled generators shall be at the maximum hydrogen pressure imposed on the generatorenclosure. The output rating,specified temperatures, and observable temperature rises shall be based only on ratedhydrogen pressure.The preferred maximum hydrogen pressures are:1)For indirectly cooled generators: 30 psig (pounds per square inch gage)2)For directly cooled generators: 30,45,60, or 75 psig
2)For directly cooled generators: 30,45,60, or 75 psig.
The capability of a synchronous generator is the highest acceptable continuous loading (kVA) through the full rangeof power factor at a specified condition.
The observable temperature rise of each of the various parts of the machine above the temperature of the cooling air,referred to as the cold air temperature, shall not exceed the values given in Table 1 when the machine is operated atoutput rating conditions. The temperature rises in Table 1 are based on a maximum cold air temperature of 40 °C.
For open machines and for parts of enclosed machines that are cooled by open ventilation passages, that is, collectorrings, the cold air temperature is the average temperature of the external air as it enters the ventilating openings of themachine.
For totally enclosed machines, the cold air temperature is the average temperature of the air leaving the cooler orcoolers. The cold air temperature at rating,when the coolers are supplied with water of the rated amount andtemperature, is usually specified as 40C.IEEE C50.13 pdf download.
