Introduction
WB-ZJ90DB driing rig integrated control system is AC rig123.net' target='_blank'>VFD control system with maximum hook load 6750KN. The systemconsists of redundancy system structure based on computer control, digital vector VFD control, digital DC drive control system and net-technique system. DW is controlled by loadbalance of four motors with high precision. It is the first deepest rigelectrical system in China. The project has passed the inspection of CNPC, and the performance of the control system have met the requiprements of design and technics.
