DESIGN AND DEVELOPMENT OF A TRAPEZOIDAL PERMANENT MAGNET SYNCHRONOUS MACHINĘ EMULATOR

Franęois LESSARD ABSTRACT

The development of technology leads inevitably to higher systems’ complexity faced by engineers. Over time, tools are often developed in parallel with the main systems to ensure their sustainability. The work presented in this document provides a new tool for testing motor drives.

In generał, this project refers to active loads, which are complex dynamie loads emulated electronically with a static converter. Specifically, this document proposes and implements a system whose purpose is to reereate the behaviour of a trapezoidal permanent magnets synchronous machinę. The ultimate goal is to connect a motor drive to the three terminal of the motor emulator, as it would with a real motor. The emulator's response then obtained, when subjected to disturbances of the motor drive, is ideally identical to the one of a real motor. The motor emulator led to a significant versatility of a test bench because the electrical and mechanical parameters of the application can be easily modified.

The work is divided into two main parts: the static converter and real-rime. Overall, these two entities form a PHIL (Power Hardware-in-the-loop) real-time simulation. The static converter enables the exchange of real power between the drive motor and the real-time simulation. The latter gives the application the intelligence needed to internet with the motor drive in a way which the desired behaviour is reereated. The main partner of this project, Opal-RT, ensures this development.
