Recently, the State Intellectual Property Office announced the patent “Oil Drilling Machine DC Microgrid Systemâ€. The applicant was Sinopec Zhongyuan Petroleum Engineering Co., Ltd. drilling three companies.
The invention relates to a direct-current micro-grid system of an oil drilling rig, belonging to the field of oil drilling rig equipment. Including power system, transmission system and DC microgrid system, DC microgrid system includes peaking device, micro power and control device, peaking device including peaking motor and flywheel energy storage device, among which micro power supply is through rectifier, DC bus and The converter is connected to the flywheel energy storage device. The micro power supplies are respectively passed through the winch energy recovery device rectifiers, boost rectifiers, and paralleled by a DC bus to the connection line between the flywheel energy storage device and the peaking motor.
The invention patent realizes the functions of flexible power output and peaking operation for different load and pulse load characteristics, reduces engine capacity and improves economy. At the same time, the DC micro-grid system has the ability to adapt to the short-time high-power output function. In the case of severe stuck-drilling, the complete electric drive with high torque, low speed and wide speed range is achieved.
