Summary: | A new kind of multifunctional energy-saving heave compensation winch(HCW) for ultra-depth floating drilling, which has functions of lifting, heave compensation and energy-recycle, is presented based on direct drive volume control(DDVC) and hydraulic transformer(HT) energy-recycle technology. The simulation model for HCW is built by using AMESim software, and the structure for the main controller of HCW is designed, which is consist of a main controller, a HT controller and a direct drive pump source(DDPS) controller. The flowrate calculation method and flowrate distribution algorithm of the main controller are studied, and a flow calculator and a flow distributor are designed. The simulation is conducted by using the established simulation model. The simulation results shows that the HCW has a good compensation performance, and its compensation accuracy meets the design requirements. So it is proved that the design scheme of HCW is feasible, the simulation model established is correct, and the designed controller based on flowrate control is effective. |
