Abstract

The invention relates to a rotor coupling double-generator parallel motor generator set assembly and protection control system. The system comprises a comprehensive protection system device; the system comprises a single-machine starting logic control module, a single-machine stopping logic control module and a single-machine excitation/field suppression logic control module. The single-machine starting logic control module controls the rotor coupling double-machine parallel motor generator set to execute single-machine starting; the single-machine outage logic control module controls the rotor coupling double-machine parallel motor generator set to execute single-machine outage; and the single-machine excitation/de-excitation logic control module controls the rotor coupling double-machine parallel motor generator set to execute excitation or de-excitation. The system control function is achieved through logic control of the comprehensive system device, the reliability of system operation is improved, the equipment investment is saved, faults can be effectively recognized, and the troubleshooting efficiency is improved.
