Beskrivning

PTG1305-405 Mobile Motor / Generator Unit is a standard laboratory for power transmission normally consists of one or two generators, which are connected to one or more transmission links which finally reach transformers, distribution units and loads.

For example, here can be seen turbine/generators in parallel on the same busbar, a synchronous machine used as a synchronous compensator in the middle of a line, a single generator unit and a heavy group of generators.

Energy transfer, load shedding, static and dynamic stability at disturbances as well as sophisticated protection schemes can be studied under realistic forms. Not to forget compensation possibilities.

Power and current paths in grid networks are complicated. The TERCO system will give understanding for this problem.

Wide range of flexibility is achieved by the mobile generator station / synchronous alternator (compensator) PTG1305.

Two sets of PTG1305-405 can operate as described or work in parallel. Modes of Operation

PTG1305-405 can also be used to compensate for system power characteristics (active and reactive) via turbine speed and generator magnetisation.
