STUDY OF THE SYNCHRONIZATION OF AN ALTERNATOR WITH THE ELECTRICAL GRID

Educational objectives
• Understand the operation of a synchronous alternator.
• Understand the rules of synchronization with the electricity grid.
• Use a synchronoscope.
• Study the wiring diagram between a speed controller and an asynchronous motor.
• Creation of the configuration of a speed controller with software.
• Study the no-load and with-load behaviour of a 3-phase asynchronous motor 1500W.
• Study the no-load and with-load behaviour of an alternator.
• Read and plot the electrical and mechanical characteristics of the motor bench.

Comprises
