| Abstract |
A high dynamic control system for the Alspa VDM 7000 medium voltage drive was implemented,
which provides fast torque response times of a few milliseconds despite the typically low switching
frequency of GTO thyristors that is necessary to achieve high efficiency. The drive system consists of
a three-level voltage source converter with active front-end and a synchronous motor. The drive has
most recently been applied for a main strip mill. It provides a maximum of 8.3 MW mechanical
power with a rated motor voltage of 3 kV.
Besides motor torque as the main control objective, the control system has to comply with a number
of additional objectives and constraints like DC link voltage regulation and balancing, current and
torque harmonics, motor flux and excitation. |
