Replacement of excitation system on TPP Zagreb, block C

After more than 40 years of successful operation, KONCAR -INEM old analog excitation system has been replaced with digital one.

On the end of last year installation and commissioning took place of new static excitation system type SEI 11E, for synchronous 150 MVA turbogenerator, for final customer HEP – Proizvodnja d.o.o. Static excitation system type SEI 11E comprises of digital voltage regulator in two channel configuration with withdrawable thyristor bridges in 1 + 1 configuration.

By using new technical and design solutions, we achieved 100% redundancy of the system. In the case of system malfunction, the stopping of generator for repairs is not required  because the same may be made while on grid.
