Synchronous generator driven by a variable speed drive
SGLab thermal power plant consists of a synchronous generator driven by a controllable variable speed motor emulating the behaviour of a steam turbine.
Measuring equipment is able to capture generator dynamics (machine swing curve) and generator load angle after opening and quickly reclosing transmission lines and different loads, and after short circuit faults. Auxiliary system is able to simulate different short circuit faults and the short circuit current is limited through reactors.
