A Comparison Between the IEEE1566 Standard for Large Adjustable Speed Drives and Comparable IEC Standards

With the emergence of the new IEEE 1566 Standard for Large Adjustable Speed Drives, and the need for providing these large drives into the Global Market place, a comparison of several world standards would be of value to Electrical Engineers. With manufacturers supplying these drives on a global basis, it would be helpful to have a comparison guide for the engineer to refer to quickly. IEEE Std 1566 was written by users, consultants and manufacturers to provide a common performance standard for large adjustable speed AC drives. The standard is a stand alone document which lists the performance requirements of all aspects of an adjustable speed drive system. It includes data sheets for the purchaser and the user plus some tutorial information. It is expected that the use of the standard will lead to less confusion and work in selection of drives, plus eventually a more durable drive system This paper will cover the IEEE 1566 and comparable IEC standards as these standards would relate to the selection of large adjustable speed drives.
