DFIG Motor Kit Software Model

The software model is composed of two sections: the Simulink model and the TestDrive user interface. The Simulink model is used to design all the components that need to be simulated. All exercises included in this document are contained within one single Simulink model with the corresponding TestDrive User Interface. This user interface is used to interact with the system in real time.

Simulink Model

The screenshot of the Simulink model below shows an overview of the set of subsystems corresponding to each exercise detailed in the next chapter.

Test Drive User Interface

The TestDrive interface is composed of one main screen that offers of series of panels (OP8660, Ex1_ IGBT, Ex2_SyncGen, Scopes, and Scopes2), each one corresponding to an exercise. The main screen displayed depends on which panel is selected. When you first start TestDrive, the center screen is blank and you must select which panel to display.

The figure shown below is the basic panel.

OP8660 Panel

The OP8660 panel is divided into three sections.

A	Panel selection buttons
B	OP8660 interface representation. Provides an interactive display of the OP8660
C	The lower interface provides a series of tabs to adjust configurations

Control Panel Section (A)

Displays the panels associated with the test bench:

OP8660	This is the main screen, displayed by default on startup.
Ex1_IGBT	This screen corresponds to Exercise 1.
Ex2_SyncGen	This screen corresponds to Exercise 2.
Scopes/Scopes2	Both Scopes screens display oscilloscope results in the lower portion of the main screen.

OP8660 Section Contents (B)

The contents of section B do not change (regardless of the tab displayed in the lower section):

6 Pulse inverter Outputs	Inverter output connectors send control pulses to the motor.
Encoder Inputs	Encoder input connectors read motor speed and position using differential ABZ encoder signals.
Analog Inputs	Analog input monitoring connectors for each channel (16).
Analog Outputs	Analog output monitoring connectors for each channel (16).
Digital Inputs	Digital input monitoring connectors for each channel (8).
Digital Outputs	Digital input monitoring connectors for each channel (8).
High Current Measurements	Probe connectors (max. 15A AC). Red and green LEDs indicate channel activity.
High Voltage Measurements	Probe connectors (max. 600 V). Red and green LEDs indicate channel activity.

Configuration Section Tabs (C)

Interfaces to modify specific configurations and values through these five tabs:

Inverter Control	For each of the two inverters, provides slides to increase or decrease the duty cycle from 0 to 1 on each of the inverter’s 3 phases, a knob and a slider to increase or decrease the PWM carrier frequency from 0 to 20,000.
Scopes	Oscilloscope display for each inverter.
Dyno Control	Scales to increase or decrease the dynamometer RPM Set Point and Maximum Torque and a button to Start/Stop.
Calibration Data	Gain and offset adjustment for the calibration of the current and voltage measurements.
Data Logging	Trigger/button to save measurements into a file and a file number.

EX1_IGBT Panel

The EX1_IGBT panel button displays the panel used for Exercise 1. (Exercise 1 details are presented in a separate document, for training purposes).

EX2_SyNcGEN Panel

The EX2_SyncGen panel button displays the panel used for Exercise 2.
