INVT GD800 inverter helps the drilling industry promote "carbon neutrality"

In the shale gas drilling rig project of a drilling company in the north, the winch motor is 400KW, the turntable motor is 300KW, and the voltage is 600V. The two motors are powered by the drive to the winch and the turntable respectively, and the control room adjusts the motor speed according to the specific drilling depth and drilling process to meet the needs of the drilling process. The zero-speed "hovering" function of the winch motor makes on-site operation easier and the work process safer. The turntable's zero-speed torque output retention function makes the torque release process easy and can easily cope with stalled rotor conditions.

Compared with the stand-alone equipment, the rectifier capacity equipment is small, the braking unit equipment is less, the equipment for equipment installation is small, and the economy of system application and later protection is better.

The system uses two sets of GD800 rectifier modules to supply power to four GD800 inverters through the DC bus, which not only considers the rectification margin, but also reasonably reduces the total installed capacity. The inverters are all selected speed vector control mode, with high control accuracy and speed echo block, and the operation is more stable and reliable.

Goodrive800 engineering transmission products are specially planned for the high-end application market, and the international mainstream modular planning concept is selected, which can be used in occasions that require high overload capacity, high reliability and continuous operation;

The selection of INVT plan has the following excellent features:

The power density is large, and the volume is reduced by more than 30% compared with the previous equipment, reducing the indoor floor space;

Shared braking unit, high equipment utilization, both economical and efficient;

The rectifier power is more than 99%, and the inverter power is more than 98.5%;

Installation and operation in front of the cabinet to facilitate the user's later equipment protection;

The system is a cabinet, with less external cross-lines, and the moving and disassembly are faster;

High power factor, up to 0.95 or more;

The system is low noise and pollution-free, making it more green and environmentally friendly.

Compared with the use of traditional diesel engine drive, the use of motor drive has many advantages, including small environmental pollution, small impact on the noise of surrounding residents, small protection workload, etc., when the winch is decelerated and lowered, the electric energy can also be fed back to the DC bus through the inverter, and then used for other equipment such as turntable and mud pump, which greatly improves the power of electric energy.

According to statistics, in the case of diesel engine drive, the daily oil consumption is about 2.5 tons, according to 7,500 yuan per ton, the daily cost is about 18,700 yuan. In the case of motor drive, the daily power consumption is about 14,000 kWh, and the daily cost is about 15,400 yuan according to 1.1 yuan/kWh. In the case of electricity, it can save at least about 3,300 yuan per day, and the energy saving effect is remarkable.

After on-site application, INVT GD800 inverter has a good echo effect and a significant power-saving effect, which is a good helper in the drilling industry, and will have a wide range of application prospects in turntables, top drives, winches and mud pumps.
