Description / Abstract:
This standard applies to ac adjustable-speed drive (ASD) systems
rated above 375 kW and above 750 V output voltage as used in
petrochemical and similar applications. It covers the performance
requirements for an ASD system including, but not limited to, input
transformer or reactor as required, power electronics, control
interfaces, cooling system, switchgear, and motor. Requirements for
power quality, engineering analysis, start-up assistance, training,
and spare parts are also included. Certain items such as the motor,
switchgear, or transformer may be excluded from the scope of vendor
supply if specified in the data sheets; the system vendor shall
specify any special requirements for the excluded equipment.
Purpose
The purpose of this standard is to assist users in defining the
required performance of a drive system in clear terms. It is not
intended to specify a particular technology that must be followed.
It is to be used with the data sheets provided in Annex A and Annex
B.
