Abstract


In view of the problems encountered in practical application of work-over rig original power "Change from oil to electricity", we propose a scheme for control system of electric work-over rig based on AC/DC hybrid micro-grid. Then take Boost circuit of Bidirectional Buck-Boost DC/DC as an example to design IDA controller. Finally, using the above research results, we design the electric work-over rig control system, and describe control method about energy balance control in this system.
