Automatic control panel for generator sets - MP12-SCR
The MP12-SCR module controls the automatic start and synchronization of the generating set to work in parallel with the other gensets upon receiving an starting signal.This starting signal is usually driven by the load transfer control module CON-2012 , that controls the mains supply and gives the start-up signal if it fails.
The MP12-SCR uses a fast start and synchronization method called "electrical axis". On receiving the starting-up signal, all the gensets begin the starting cycle with the power circuit breakers closed.
Thus, using a controlled excitation current, the alternators synchronization is produced simultaneously to the starting process of diesel engines, which provides the maximum speed.
However, the user may program the module operation for the "classical method" of synchronization and parallel operation: All the sets start with opened circuit breakers, the first available set will be connected to bars and the others will in turn automatically synchronise and be connected in parallel with the first one put into service.
Once all the sets are started and synchronized, the "available service in bars" signal is given to the load transfer control equipment in order it could connect the load to the gensets.
Each generating set in parallel includes its own MP12-SCR control panel, with all the benefits explained in this catalog for the AUT-MP12 module, and those provided by the gensets operating in parallel. For example, the "genset measurements" display shows the electrical data of the genset.
