ECE462: Power Systems Laboratory

Course Info: A series of 9 laboratory experiments (6 require one week each and three require three weeks each to complete. The experiments cover DSP based control of DC PMDC and synchronous motors. A Simulink model (*.mdl) of a DC switchmode power converter will be built. After verifying the stimulation results with Simulink model, the model will be modified to control the output of the power converter in realtime. A DCmotor will be connected to the output of the power converter. With this arrangement, a variable voltage can be applied to the terminals of the DCmotor to observe openloop speed control of a DC motor; two, calculate the motor backemf constant kE as well as a the electrical parameters (Ra and La) of the motor using the blocked rotor test. In addition the mechanical characteristics B and J will be determined. The torque speed characteristics will be verified. Students implement a closeloop speed control of a DCmotor drive for which the parameters were calculated. Once the parameters are tuned, the model of the DCmotor will be replaced with the real motor. The tuned controllers will be implemented in realtime on DS1104 to perform the closeloop speed control of the DCmotor. The magnetizing inductance (Lm>>Lls) will be calculated by running the induction motor at synchronous speed, at rated voltage and rated frequency. The rotor circuit parameters i.e. Llr and R' will be calculated by blockedrotor test while injecting slip frequency at the stator terminals. Finally, the torque speed characteristics of a three phase induction motor are measured and students observe the induction motor in generation mode (super synchronous speed) and motoring mode (sub synchronous speed)
