[v2] Application Test Rig DFIG-based Wind Energy Conversion System in RCP configuration

The figure below depicts a test rig of a Wind Energy Conversion System (WECS) for Rapid Control Prototyping that includes all the main components of the EC-2KW kit, whose features and specifications are covered in Chapter 2 of this guide.

A dynamometer (or AC servo drive) (#1) acting as a wind turbine emulator drives a Wind Rotor Induction Machine (WRIM or DFIG) (#2) which in turn is controlled through a back-to-back power converter (#3).
Electrical (currents, voltages) and mechanical (angular position, speed) signals necessary for controlling the system are measured and conditioned by a Signal Conditioning Module (#4).

The conditioned signals are processed by a Real-Time Simulator (RTS) (#5) programmed with the control algorithm under test.
Said control algorithm is uploaded to the RTS through a so-called host computer (#6) that runs both RTS’s software (#7) and the modeling and control software environment (#8) in which the control algorithm is developed.

Additionally, as also shown in the figure below, the RTS can generate a wind profile characteristic that controls the operation of the dynamometer so that the {test rig/set-up/wind emulator} can replicate the operation of a WECS in Maximum Power Point Tracking Mode (MPPT)
The dynamometer is operated either through a torqueor speed reference command transmitted by the RTS through an asynchronous communication interface (#9).
The communication interface can also be employed to read and configure any other parameter important for the control of the DFIG-based WECS emulator.
