2013 update on the revision plan for IEEE C50.13 and harmonization with IEC 60034 standards for large cylindrical rotor synchronous machines

This report is a progress report by the Generator Subcommittee of the Electrical Machinery Committee of the IEEE Power and Energy Society, Working Group No. 8 (“IEEE C50.13 Review & Compare”). The working group is comparing the 2005 revision of the IEEE C50.13 standard for large round rotor synchronous generators with recent revisions of comparable International Electrotechnical Commission (IEC) 60034 standards. In this paper the working group reports progress made since starting in 2007, summarizes completed results, and outlines plans for next steps. Included are highlights of an incrementally improved C50.13 that is to be submitted for balloting in 2013 and highlights of future improvements that will be pursued after 2013. Also included is a synopsis of suggestions provided to the IEC for harmonization of IEC 60034 with IEEE C50.13. Finally, the paper includes an overview of a 2012 PES panel session to discuss grid code impacts on electric machine design and performance.
