Abstract

In industrial installations with several drives, total peak power will often be equal to the sum of all individual peak powers. This article demonstrates that through proper interaction between drives, peak power can be very much limited, sometimes by a factor two. This is done by controlling the power of one or more drives connected to high-inertia loads as a function of the power required for control of highly dynamic loads. The feasibility is demonstrated on a hybrid servo press installation, where an existing flywheel is used as a buffer for a newly installed servo drive. Practical implementation issues are discussed and measurements from a prototype installation are presented.
