Overview
Brief Description
This unit will build on the material covered in the level 2 programme unit 'Machines, Drives and Power Electronics' to cover the selection, configuration and control of electrical machines and their associated power converters for a range of applications. Energy recovery from the load to the power network will also be included.
The unit will cover the following:
- Reasons for using an electrical drive system, with examples across a range of applications. Drive system design for torque or speed control or control of other mechanical or electrical system variables.
- Drive specification and selection, based on the torque-speed characteristic of the load and the torque-speed envelope of the motor, including field weakening. Driving and braking torque requirements of accelerating and decelerating loads.
- Induction machines: comparison of energy use with direct-on-line operation, variable voltage control, scalar voltage/frequency control and variable resistance control; machine and drive system analysis; effect of terminal harmonics.
- Synchronous machines: steady-state analysis of wound field and permanent magnet brushless machines, two-axis theory (d-q) to introduce closed-loop vector control and advanced control philosophies.
- Elements of a typical electrical drive system and their configuration including: the power electronic interface; current and voltage control methods; 4-quadrant operation; energy recovery; dump resistor sizing; sensing; protection; switchgear and the controller platform.
