9 Wiring Module for Wound-Rotor Induction Motor (DFIG) 8506-A5 The Wiring Module for Wound-Rotor Induction Motor consists of a connection module. It provides connection access to the Three-Phase Wound-Rotor Induction Motor from the workstation through a flexible connecting cable. The module has ten 4-mm color-coded safety jacks for the power windings and six 2-mm jacks for the search coils. Jacks of different sizes prevent accidental connections between power windings and search coils. 212 x 287 x 496 mm (8.3 x 11.3 x 19.5 in) 4.1 kg (9.0 lb) Variable Power Supply The Power Supply module is the primary component of the system. All associated equipment is powered by this power supply. A flexible, 5-wire power cord, terminated with a 5- prong, twist-lock plug and line cap, feeds the module. A mechanical interlock on the line cap prevents the removal of an energized Power Supply from its locked position in the workstation. The Power Supply requires a 3-phase, wye-connected, 5- wire service installation. An appropriate wall outlet is shipped with each Power Supply so that site power can be properly terminated to receive the power cord. In addition to the 3-phase legs and the neutral, a separate copper ground provides proper grounding for the Power Supply chassis and workstation cabinets, thus ensuring added safety for students using the equipment. The Power Supply provides fixed and variable ac and dc voltage sources all terminated with 4 mm safety jacks. They can be used simultaneously, up to a total load current equal to the rating of the fixed 3-phase output. Independent circuit breakers, reset at the front panel, protect the Power Supply input and outputs. Indicator lamps monitor the presence of input voltage in each phase. When a phase leg of the site power service is out, the lamp goes off to reflect this condition. A voltmeter, connected through a selector switch, monitors the outputs. The Variable Power Supply is available in different variants depending on ac power network voltages and frequencies. Because of this, the actual module may vary from the one shown in the picture.

The Four-Quadrant Dynamometer consists of a squirrel-cage induction motor with an encoder feedback. The motor is driven by a closed-loop vector drive which is coupled to a touchscreen Human-Machine Interface (HMI). This interface enables the user to select the mode of operation (speed or torque) and to set either the speed (r/min) and direction or the output torque (N m or lb ft) of the machine. The interface displays the main parameters of operation in real-time (voltage, current, torque, speed, and frequency). Electrical connections between the vector drive and the motor are made through jumpers on the front panel. This makes the separation of both components simple and allows the motor or the vector drive to be used independently in other experimentations. The vector drive is well protected against abuse. 10 Festo Didactic

11 The vector drive stops if a problem occurs, with the LCD showing the current alarm along with its description. The user is then able to reset the alarm and resume normal operation. The model can also be interfaced with a computer for monitoring and control.

The Power Electronics Devices are used to filter and convert electrical power flowing in electric circuits. They come as half-size EMS modules equipped with a steel front panel. Internal electrical components are identified on the module front panel by silkscreened symbols. This module consists of 7 insulated-gate bipolar transistors (IGBT) mounted in a half-size EMS module. Six IGBTs are used to implement choppers and inverters. These IGBTs are protected against a variety of severe operating conditions, such as short-circuits, overvoltage, overcurrent, and overheat. The seventh IGBT and an external dumping resistor allow smooth dissipation of excess energy at the DC bus. The dumping circuit can be activated through the use of a toggle switch on the front panel. The module switching control section allows 0/5 V pulse signals from either the Data Acquisition and Control Interface, Model 9063, the Chopper/Inverter Control Unit, Model 9029, or any compatible 0/5 V control unit, to be applied to the gating circuits of the IGBTs. The signals are input in the IGBT Chopper/Inverter module through a 9 pin connector. Six miniature banana jacks are used as test points to monitor the pulse signals using an oscilloscope. Festo Didactic 11

12 These jacks can also be used to inject 0/5 V pulse signals from an alternate control unit, as well as to inhibit each gating circuit. The IGBT Chopper/Inverter module also includes a synchronization output to trigger an oscilloscope when observing the switching control signals as well as a switching control disable input that allows all six IGBTs in the chopper/inverter section to be switched off.
