Application Scenarios:
In a massive hydropower station,the stability of the entire regional power grid hinges on the performance of the generators.A key component in ensuring this stability is the static exciter system,which controls the generator’s field current and,in turn,its output voltage.At the heart of this exciter system is a series of Thyristor modules.The engineering team selected the ABB S-093S/3BHB030475R0009 for its proven reliability and precise switching characteristics.The module’s ability to accurately phase-control the high AC current to the generator’s field winding ensures that the output voltage remains constant,even under fluctuating load conditions.This not only protects the generator from over-excitation but also prevents power quality issues that could affect the entire grid.
