Recently, the configurational flexibility of the TJ-II has been broadened by the commissioning of a new mode of operation that allows magnetic configurations to be varied dynamically during the discharge flat-top. In order to achieve this, new hardware and software features have been added to the TJ-II Control System.

Installation of the TJ-II flywheel generator

The generation of the magnetic field during a TJ-II discharge requires a total amount of power of almost 50 MW. This power is supplied by the national grid and a 140 MW flywheel generator (100 MJ, 15 kV, 100 Hz). As the TJ-II loads require a direct current, a set of thyristor converters, transformers and circuit breakers are used for each coil system. The power requirements range from 5 kA (100 V) to 32 kA (1000 V). The heating systems (ECRH and NBI) load the power supply with additional 15 MW. [1] [2] [3] [4]

The TJ-II flywheel generator

Recently, the configurational flexibility of the TJ-II has been broadened by the commissioning of a new mode of operation that allows magnetic configurations to be varied dynamically during the discharge flat-top. In order to achieve this, new hardware and software features have been added to the TJ-II Control System. [5]
