The laboratory work consists of 3.5 days experiment. This lab work has to be performed in groups of  8 students in the laboratory of Electrical Power Processin in TUDelft.

In total there are 3 experiments;

• Setup and DC Machine
• Induction machine
• Synchronous machine

After performing these experiments the students should hand in a paper.

Setup and DC Machine

This is the first experiment and is an instruction to setup the experiments and working with DC Machines.

The Study goals are;

• Be familiar with the setup (machines, drivs) used in the laboratory work.
• Be able to realize an operating point of a DC machine with a bidirectional thyristor bridge converter, sometimes called a dual converter (the Siemens DC controller)
• Be able to realize an operating point of an induction machine with three-phase inverter
• Know the no-load characteristics of a DC machine.

Induction Machine

This is the second experiment and deals with Induction machines.

The Study goals of this experiment are;

• Be able to determine the parameters of the equivalent circuit of an induction machine.
• Use these parameters to make a graph of the torque/speed characteristic.
• Use these parameters to make a graph of the Heyloand circle (the trajectory of the current phasor in the complex plane as a function of the speed or the slip).

Synchronous Machine

This is the third and the last experiment and is about Synchronous machines. Synchronous machines are mostly used as a generators. They can be used in island operation, for example on board of a ship or an aircraft, or connected to the grid, for  example in a power station or a combined heat and power unit. In this experiment, both will be tested.

The Study goals of this experiment are;

• Be familiar with synchronous machines
• Be able to synchronize a synchronous machine with the grid
• Be able to realize different operating points(generator and motor operation, leading and lagging power factor) in island operation as well as grid connected
• Be able to explain what they see in the experiments using phasor diagrams.
